EasyUI的DataGrid绑定Json数据源的示例代码

EasyUI给表格绑定数据是最常用的方法，小编分享一下总结出来的两种绑定表格方法，知识在于积累。

第一种：数据存放在数据集中，每一行对应多个值，利用循环把数据绑定到表格

前台代码：

<table id="dg" class="easyui-datagrid" style="width:100%;height:100%;" title="需要设置表格标题" data-options="         rownumbers:true,         singleSelect:true,         @*autoRowHeight:false,*@         pagination:true         @*pageSize:10*@">       <thead>         <tr>           <th field="colum1">列1</th>           <th field="colum2">列2</th>           <th field="colum3">列3</th>           <th field="colum4">列4</th>           <th field="colum5">列5</th>           <th field="colum6">列6</th>         </tr>       </thead>     </table>

JS代码：

(function ($) {   function pagerFilter(data) {     if ($.isArray(data)) { // is array       data = {         total: data.length,         rows: data       }     }     var target = this;     var dg = $(target);     var state = dg.data('datagrid');     var opts = dg.datagrid('options');     if (!state.allRows) {       state.allRows = (data.rows);     }     if (!opts.remoteSort && opts.sortName) {       var names = opts.sortName.split(',');       var orders = opts.sortOrder.split(',');       state.allRows.sort(function (r1, r2) {         var r = 0;         for (var i = 0; i < names.length; i++) {           var sn = names[i];           var so = orders[i];           var col = $(target).datagrid('getColumnOption', sn);           var sortFunc = col.sorter || function (a, b) {             return a == b ? 0 : (a > b ? 1 : -1);           };           r = sortFunc(r1[sn], r2[sn]) * (so == 'asc' ? 1 : -1);           if (r != 0) {             return r;           }         }         return r;       });     }     var start = (opts.pageNumber - 1) * parseInt(opts.pageSize);     var end = start + parseInt(opts.pageSize);     data.rows = state.allRows.slice(start, end);     return data;   }    var loadDataMethod = $.fn.datagrid.methods.loadData;   var deleteRowMethod = $.fn.datagrid.methods.deleteRow;   $.extend($.fn.datagrid.methods, {     clientPaging: function (jq) {       return jq.each(function () {         var dg = $(this);         var state = dg.data('datagrid');         var opts = state.options;         opts.loadFilter = pagerFilter;         var onBeforeLoad = opts.onBeforeLoad;         opts.onBeforeLoad = function (param) {           state.allRows = null;           return onBeforeLoad.call(this, param);         }         var pager = dg.datagrid('getPager');         pager.pagination({           onSelectPage: function (pageNum, pageSize) {             opts.pageNumber = pageNum;             opts.pageSize = pageSize;             pager.pagination('refresh', {               pageNumber: pageNum,               pageSize: pageSize             });             dg.datagrid('loadData', state.allRows);           }         });         $(this).datagrid('loadData', state.data);         if (opts.url) {           $(this).datagrid('reload');         }       });     },     loadData: function (jq, data) {       jq.each(function () {         $(this).data('datagrid').allRows = null;       });       return loadDataMethod.call($.fn.datagrid.methods, jq, data);     },     deleteRow: function (jq, index) {       return jq.each(function () {         var row = $(this).datagrid('getRows')[index];         deleteRowMethod.call($.fn.datagrid.methods, $(this), index);         var state = $(this).data('datagrid');         if (state.options.loadFilter == pagerFilter) {           for (var i = 0; i < state.allRows.length; i++) {             if (state.allRows[i] == row) {               state.allRows.splice(i, 1);               break;             }           }           $(this).datagrid('loadData', state.allRows);         }       });     },     getAllRows: function (jq) {       return jq.data('datagrid').allRows;     }   }) })(jQuery);
