easyui datagrid 动态拼接columns以及赋值

需求背景如下:

后台java代码动态拼接datagrid的columns,然后赋值,实现过程如下:

后台java代码拼接过程,只是举个例子,可以根据具体业务拼接:

java代码:

     
     Map<String, Object> map = new HashMap<String,Object>();
     StringBuffer cols = new StringBuffer(); cols.append("[["); cols.append("{field:\"field0\",title:\"field0title\",width:80}").append(","); cols.append("{field:\"field1\",title:\"field1title\",width:80}"); cols.append("]]"); StringBuffer data = new StringBuffer(); data.append("["); data.append("{\"field0\":\"1\"").append(",").append("\"field1\":\"2\"").append("}").append(","); data.append("{\"field0\":\"11\"").append(",").append("\"field1\":\"22\"").append("}"); data.append("]"); map.put("columns", cols.toString()); map.put("data", data.toString());

把map输出到前台页面,之后前台页面在ajax请求成功后的回调函数里写:

        var colObject = eval("(" + res.columns + ")");
        var dataObject = eval("(" + res.data + ")");
        $("#grid").datagrid({
            columns:colObject,
            data:dataObject
        });

效果如下:
