JqueryEasyUI之DataGrid扩展

DataGrid通用合并扩展方法：

$.extend($.fn.datagrid.methods, {
    autoMergeCells: function (jq, fields) {
        return jq.each(function () {
            var target = $(this);
            if (!fields) {
                fields = target.datagrid("getColumnFields");
            }
            var rows = target.datagrid("getRows");
            var i = 0,
            j = 0,
            temp = {};
            for (i; i < rows.length; i++) {
                var row = rows[i];
                j = 0;
                for (j; j < fields.length; j++) {
                    var field = fields[j];
                    var tf = temp[field];
                    if (!tf) {
                        tf = temp[field] = {};
                        tf[row[field]] = [i];
                    } else {
                        var tfv = tf[row[field]];
                        if (tfv) {
                            tfv.push(i);
                        } else {
                            tfv = tf[row[field]] = [i];
                        }
                    }
                }
            }
            $.each(temp, function (field, colunm) {
                $.each(colunm, function () {
                    var group = this;

                    if (group.length > 1) {
                        var before,
                        after,
                        megerIndex = group[0];
                        for (var i = 0; i < group.length; i++) {
                            before = group[i];
                            after = group[i + 1];
                            if (after && (after - before) == 1) {
                                continue;
                            }
                            var rowspan = before - megerIndex + 1;
                            if (rowspan > 1) {
                                target.datagrid('mergeCells', {
                                    index: megerIndex,
                                    field: field,
                                    rowspan: rowspan
                                });
                            }
                            if (after && (after - before) != 1) {
                                megerIndex = after;
                            }
                        }
                    }
                });
            });
        });
    }
});

调用方法：

//加载成功后调用此方法
function onLoadSuccess(data) {
    $(this).datagrid("autoMergeCells", ['No', 'NativePlace','填写字段名称']);

}

HTML代码:

<table class="easyui-datagrid" title="Merge Cells for DataGrid" style="width:700px;height:450px"
        data-options="
            rownumbers: true,
            singleSelect: true,
            iconCls: 'icon-save',
            url: '/Home/GetEmployee',
            method: 'get',
            rownumbers:true,
            pagination:true,
            onLoadSuccess:onLoadSuccess
        ">
    <thead>
        <tr>
            <th data-options="field:'EmployeeID',width:300">员工编号</th>
            <th data-options="field:'No',width:100">登录名</th>
            <th data-options="field:'RealName',width:100,align:'right'">真实名字</th>
            <th data-options="field:'NativePlace',width:80,align:'right'">地区</th>
            <th data-options="field:'status',width:60,align:'center'">操作</th>
        </tr>
    </thead>
</table>
