web项目 easyui-datagrid开发实践

2022-12-04,,,,

一，引言

工作的需要，做了3年的wpf(mvvm)……，又因为项目的需求，回归到web的开发。

■  3 years ago，vue是我三年前没用过的玩意儿。

■  3 years ago，bootstrap组件没现在成熟。

■  3 years ago，font awesome的普及度没有现在高。

■  3 years ago，ui组件的选择也没有现在多。

二，项目的前端（easyui模板订制）

整个项目采用了oracle  + dapper  + castle + mvc + easyui的技术结合，本篇博客重点介绍easyui。

easyui的默认风格看久了很容易产生视觉疲劳，在这个项目中，我个性化订制风格。

订制easyui模板的工作量是挺大的，我用了一个偷懒的方法，花了几百块钱在网上买了几个easyui的皮肤（链接）然后对这些皮肤，进行优化和重构。

money比较紧的同学，可以去下载easyui的免费皮肤。

三，easyui-datagrid的基本使用：

1，加载数据

a，通过post，url的方法向后端请求数据，如图所示：

            $('#List').datagrid({

                title: "交易公司",

                loadMsg: '@CommonResource.Processing',

                toolbar: '#tb',

                width: "100%",

                height: "100%",

                //idField:"ID",

                //data: getData(),

                url: "@Url.Action("GetList")",

                methord: 'post',

                rownumbers: true,

                autoRowHeight: false,

                fit: true,

                //fitColumns: true,

                striped: true,      //奇偶行

                singleSelect: true,//单选模式

                checkOnSelect: false,

                selectOnCheck: false,

                collapsible: true,

                pagination: true,

                pageNumber: 1,

                pageSize: 10,

                pageList: [10, 20],

                queryParams: { },

                columns: [[

                    { field: 'Company_Name', title: '公司名称', width: 100, sortable: false },

                    { field: 'Abbreviation', title: '简称', width: 100, sortable: false },

                    { field: 'Business_Address', title: '经营地址', width: 100, sortable: false },

                    { field: 'Registered_Address', title: '注册地址', width: 100, sortable: false },

                    { field: 'Tel', title: '电话', width: 100, sortable: false },

                    { field: 'Fax', title: '传真', width: 100, sortable: false },

                    { field: 'Contactor', title: '联系人', width: 100, sortable: false },

                    { field: 'Payment', title: '结算方式', width: 100, sortable: false },

                    { field: 'Beneficiary_Name', title: '开户名称', width: 100, sortable: false },

                    { field: 'Beneficiary_Address', title: '开户地址', width: 100, sortable: false },

                    { field: 'Advising_Bank', title: '通知行', width: 100, sortable: false },

                    { field: 'Bank_Address', title: '银行地址', width: 100, sortable: false },

                    { field: 'Swift_Code', title: '银行代码', width: 100, sortable: false },

                    { field: 'Beneficiary_Account', title: '银行账户', width: 100, sortable: false },

                    { field: 'Company_Chop', title: '电子章', width: 100, sortable: false },

                    { field: 'Send_Url', title: '发件邮箱链接', width: 100, sortable: false },

                    { field: 'Send_Email', title: '发件人邮箱', width: 100, sortable: false },

                    { field: 'Remark', title: '备注', width: 100, sortable: false },

                    { field: 'Created_By', title: '创建人', width: 100, sortable: false },

                    { field: 'Creation_Date', title: '创建日期', width: 100, sortable: false },

                    { field: 'Modify_By', title: '修改人', width: 100, sortable: false },

                    { field: 'Modify_Date', title: '修改日期', width: 100, sortable: false },

                ]],

            });

        });

b，先定义好了datagrid的属性以及列，再通过loadData的方法设置datagrid的数据

$('#Detail').datagrid({

    loadMsg: '@CommonResource.Processing',

    toolbar: '#tb',

    width: "100%",

    height: "100%",

    //data: [],

    rownumbers: true,

    autoRowHeight: false,

    fit: true,

    fitColumns: true,

    striped: true,

    singleSelect: true,

    collapsible: false,

    pagination: false,

    queryParams: {  },

    columns: [[

        { field: 'Country_Name', title: '国家名称', width: 100, sortable: false },

        { field: 'Item_Number', title: '物料编码', width: 100, sortable: false },

    ]],

});
var returnData = JSON.parse(response.data);

$('#Detail').datagrid("loadData", returnData);

2，合并单元格

有时候用户需要如下图的效果

可以在datagrid的onLoadSuccess事件里增加如下代码：

onLoadSuccess: function (data) {

    //var opts = $('#List').datagrid('getColumnFields');

    var opts = new Array("Item_Number", "Country_Name", "Item_Desc", "Item_Desc_En", "Item_Type", "Unit", "Hs_Code", "Destination_Code", "Status", "Remark", "Create_User", "Create_Date");

    var rowsCount = data.rows.length;

    var mark = 1;

    for (var j = 1; j < rowsCount; j++)

    {

        var preCellVal = data.rows[j - 1]["Material_Id"];

        var currentCellVal = data.rows[j]["Material_Id"];

        if (preCellVal == currentCellVal) {

            mark += 1;

            for (var c = 0; c < opts.length; c++) {

                var columnName = opts[c];

                $(this).datagrid('mergeCells', {

                    field: columnName,

                    index: j + 1 - mark,

                    rowspan: mark

                });

            }

        }

        else {

            mark = 1;

        }

    }

},

3，行，列变色

针对这样的行，列变色效果：

a，行变色

$('#Detail').datagrid({

    loadMsg: '@CommonResource.Processing',

    toolbar: '#tb',

    width: "100%",

    height: "100%",

    url: "@Url.Action("GetLines")",

    methord: 'post',

    rownumbers: true,

    autoRowHeight: false,

    fit: true,

    fitColumns: true,

    striped: true,

    singleSelect: true,

    collapsible: false,

    pagination: false,

    queryParams: { hid: $("#Hid").val() },

    columns: [[

        { field: 'Material_No', title: '物料号', width: 100, sortable: false },

        { field: 'Description', title: '中文描述', width: 100, sortable: false },

        { field: 'En_Description', title: '英文描述', width: 100, sortable: false },

        { field: 'Unit', title: '单位', width: 100, sortable: false },

        { field: 'Quantity', title: '工单数量', width: 100, sortable: false },

        { field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 100, sortable: false },

        { field: 'Remark', title: '备注', width: 100, sortable: false },

    ]],

    rowStyler: function (index, row) {

        if (row.Quantity == 0) {

            return 'background-color:pink;color:blue;font-weight:bold;';

        }

    },

});

b，列变色

$('#Detail').datagrid({

    loadMsg: '@CommonResource.Processing',

    width: "100%",

    height: "100%",

    data: [],

    rownumbers: true,

    autoRowHeight: false,

    fit: true,

    fitColumns: true,

    striped: true,

    singleSelect: true,

    checkOnSelect: false,

    selectOnCheck: false,

    collapsible: false,

    pagination: false,

    queryParams: {},

    columns: [[

        { field: 'sel', checkbox: true },

        { field: 'Material_No', title: '物料号', width: 80, sortable: false },

        { field: 'Description', title: '中文描述', width: 80, sortable: false },

        { field: 'Unit', title: '单位', width: 80, sortable: false },

        { field: 'Quantity', title: '工单数量', width: 80, sortable: false },

        { field: 'Total_Actual_Send_Quantity', title: '已出货数量', width: 80, sortable: false },

        { field: 'Remain_Quantity', title: '剩余数量', width: 80, sortable: false },

        {

            field: 'Actual_Send_Quantity', title: '本次出货', width: 80, sortable: false,

            editor: { type: 'numberbox', options: { required: true, min: 0 }, },

            styler: function (value, row, index) {

                return 'background-color:#ecffff;';

            },

        },

        {

            field: 'Remark', title: '备注', width: 80, sortable: false,

            editor: { type: 'textbox', options: { validType: 'length[1,20]' }, },

            styler: function (value, row, index) {

                return 'background-color:#ecffff;';

            },

        },

    ]],

4，为datagrid添加工具条

如下效果的工具条，是通过datagrid的 toolbar 属性来指定，要留意的是toolbar的控件名称需要加上#符号。

html代码：

<div id="tb">

    <a id='condition' href='#' class='btn btn-default more'><i class='fa  fa-ellipsis-v'></i>&nbsp;&nbsp;查询条件</a>

    @Html.ToolButton(string.Format(@"<a id='btnCreate' href='#' class='btn btn-default'><i class='fa fa-plus'></i>&nbsp;&nbsp;{0}</a>", @CommonResource.Add), ActionCode.Create)

    @Html.ToolButton(string.Format(@"<a id='btnEdit' href='#' class='btn btn-default'><i class='fa fa-pencil'></i>&nbsp;&nbsp;{0}</a>", @CommonResource.Edit), ActionCode.Edit)

    @Html.ToolButton(string.Format(@"<a id='btnDelete' data-content='Delete 1' href='#' class='btn btn-primary'><i class='fa fa-trash'></i>&nbsp;&nbsp;{0}</a>", @CommonResource.Delete), ActionCode.Delete)

</div>

js代码：

5，做增，删，改操作

a,为datagrid增加一行

function addCallBack(data) {

    $('#List').datagrid('insertRow', {

        index: 0,

        row: data,

    });

    layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

}

b,为datagrid编辑一行

function editCallBack(data) {

    var selectData = $('#List').datagrid('getSelected');

    var selectIndex = $('#List').datagrid('getRowIndex', selectData);

    $('#List').datagrid('updateRow', {

        index: selectIndex,

        row: data,

    });

    layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });

}

c,为datagrid删除一行

$("#btnLineDelete").click(function () {

    var row = $('#Detail').treegrid('getSelected');

    if (row != null) {

        var rowIndex = $('#Detail').datagrid('getRowIndex', row);

        $('#Detail').datagrid('deleteRow', rowIndex);

        layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });

    }

    else {

        layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

    }

});

d,treegrid的操作方法略有区别，附上源码：

    function addCallBack(data) {

        var row = $('#List').treegrid('getSelected');

        $('#List').treegrid('append', {

            parent: data.Parent_Id,

            data: [{

                Id: data.Id,

                Name: data.Name,

                En_Name:data.En_Name,

                Code: data.Code,

                Enable: data.Enable,

                Sort: data.Sort,

            }]

        });

        layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

    }

    function editCallBack(data) {

        var row = $('#List').treegrid('getSelected');

        $('#List').treegrid('update', {

            id: row.Id,

            row: {

                Name: data.Name,

                En_Name: data.En_Name,

                Code: data.Code,

                Enable: data.Enable,

                Sort: data.Sort,

            }

        });

        layer.msg('@CommonResource.ModifySuccess', { icon: 1, time: 1000 });

    }

    $("#btnDelete").click(function () {

        var row = $('#List').treegrid('getSelected');

        if (row != null) {

            layer.confirm('@CommonResource.ConfirmDelete', {

                btn: ['@CommonResource.Sure', '@CommonResource.Cancel'],

                shadeClose: true,

            }, function () {

                if (row.ChildCount == 0 || typeof (row.ChildCount) == 'undefined') {

                    $.post("@Url.Action("Delete")/" + row.Id, function (data) {

                        if (data == "1") {

                            $("#List").treegrid('remove', row.Id);

                            layer.msg('@CommonResource.DeleteSuccess', { icon: 1, time: 1000 });

                        }

                        else {

                            layer.msg('@CommonResource.DeleteFailed', { icon: 2, time: 1000 });

                        }

                    }, "json");

                }

                else {

                    layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

                }

            }, function () {

            });

        }

        else {

            layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

        }

    });

6，编辑单元格

具体代码实现

        var taxTypeList = JSON.parse($("#taxTypeList").val());

        var manufactureList = JSON.parse($("#manufactureList").val());

        $.extend($.fn.datagrid.methods, {

            editCell: function (jq, param) {

                return jq.each(function () {

                    var opts = $(this).datagrid('options');

                    var fields = $(this).datagrid('getColumnFields', true).concat($(this).datagrid('getColumnFields'));

                    for (var i = 0; i < fields.length; i++) {

                        var col = $(this).datagrid('getColumnOption', fields[i]);

                        col.editor1 = col.editor;

                        if (fields[i] != param.field) {

                            col.editor = null;

                        }

                    }

                    $(this).datagrid('beginEdit', param.index);

                    for (var i = 0; i < fields.length; i++) {

                        var col = $(this).datagrid('getColumnOption', fields[i]);

                        col.editor = col.editor1;

                    }

                });

            }

        });

        var editIndex = -1;

        function endEditCal() {

            if (editIndex == -1) {

                return true;

            }

            if ($('#Detail').datagrid('validateRow', editIndex)) {

                $('#Detail').datagrid('endEdit', editIndex);

                editIndex = -1;

                return true;

            }

            else {

                return false;

            }

        }

        $('#Detail').datagrid({

            loadMsg: '@CommonResource.Processing',

            toolbar: '#tb',

            width: "100%",

            height: "100%",

            data: JSON.parse($("#MaterialDetailListStr").val()),

            rownumbers: true,

            autoRowHeight: false,

            fit: true,

            fitColumns: true,

            striped: true,

            singleSelect: true,

            collapsible: false,

            pagination: false,

            queryParams: {  },

            columns: [[

                {

                    field: 'Material_Use', title: '用途', width: 100, sortable: false,

                    formatter: function (value) {

                        for (var i = 0; i < manufactureList.length; i++) {

                            if (manufactureList[i].Key == value) return manufactureList[i].Value;

                        }

                        return value;

                    },

                    editor: {

                        type: 'combobox',

                        options: {

                            valueField: 'Key',

                            textField: 'Value',

                            data: manufactureList,

                            required: true,

                            panelHeight: "auto",

                            editable:false,

                        }

                    },

                },

                {

                    field: 'Tax_Type', title: '税别', width: 100, sortable: false,

                    formatter: function (value) {

                        for (var i = 0; i < taxTypeList.length; i++) {

                            if (taxTypeList[i].Key == value) return taxTypeList[i].Value;

                        }

                        return value;

                    },

                    editor: {

            else {

                layer.msg('@CommonResource.Noselectedrecord', { icon: 2, time: 1000 });

                    type: "Post",

                    data: $("form").serialize(),

                    dataType: "json",

                    success: function (data) {

                        if (data.Key == "1") {

                            parent.$("#List").datagrid('reload');

                            var index = parent.layer.getFrameIndex(window.name);

                            parent.layer.close(index);

                            parent.layer.msg('@CommonResource.AddSuccess', { icon: 1, time: 1000 });

                        }

                        else {

                            layer.msg("物料编号'" + data.Value.Item_Number + "'在数据库中已添加", { icon: 2, time: 1000 });

                        }

                    },

                    error: function (jqXHR, textStatus, errorThrown) {

                        layer.msg('@CommonResource.AddFailed', { icon: 2, time: 1000 });

                    }

                });

            }

        });

7，重置datagrid布局  $('#List').datagrid("resize");

$(function () {

    $(".more").click(function () {

        $(this).closest(".conditions").siblings().toggleClass("hide");

        $('#List').datagrid("resize");

    });

})

 四，总结

这些技巧，在帮助文档里也说的很详细，我只是把这些技术用于实践。喜欢的可以点个“推荐”，让更多的同学能从中受益。
