easyui datagird 列宽自适应

代码如下：

 onLoadSuccess: function (data) {
                 var rows = data.rows; //得到行数据
                 var columnMaxCharacter = new Array(); //该列最大字符数
                 //遍历所有行数据,获得该列数据的最大字符数
                 var propertys = Object.getOwnPropertyNames(rows[0]);
                 for (var i = 0; i < rows.length; i++) {
                     for (var j = 0; j < propertys.length; j++) {
                         var s = eval('rows[' + i + '].' + propertys[j]);
                         //s = s.replace('<center>', ''); //屏蔽html标签
                         //s = s.replace('</center>', '');
                         if ((typeof columnMaxCharacter[propertys[j]]) == 'undefined') {
                             columnMaxCharacter[propertys[j]] = 0;
                         }
                         if ( s != null) {
                             if (s.length > columnMaxCharacter[propertys[j]]) {
                                 columnMaxCharacter[propertys[j]] = s.length;
                             }
                         }
                     }
                 }

                 //设置列宽度和字体
                 for (var j = 0; j < rows.length; j++) {
                     //得到该列的字体
                     //    alert($("td[field='"+cls[j]+"'] div").get(0).currentStyle);
                     // var fontSize=$("td[field='"+cls[j]+"'] div").get(0).currentStyle.fontSize;//获得字体大小
                     //  fontSize= fontSize.replace("px","");//去掉px方便运算
                     var fontSize = 12;
                     var w = fontSize * (columnMaxCharacter[propertys[j]] + 1); //求出宽度
                     //设定该列的宽度
                     $("td[field='" + propertys[j] + "'] div").width(w);
                 }

             }
