EasyUI--datagrid中编辑器(editor)的类型为combobox的值得绑定

1.绑定固定的值

<span style="font-family:Microsoft YaHei;"> $(function () {  
            /**管道级别*/  
            var pipingLevel = [{"value":"1","text":"A级"},{"value":"2","text":"B级"},{"value":"3","text":"C级"}];//json格式  
            function levelformmat(value){  
                if(value==0){  
                    return ;  
                }  
                for(var i =0;i<pipingLevel.length;i++){  
                    if(pipingLevel[i].value==value){  
                        return pipingLevel[i].text;  
                    }  
                }  
            }  
             $("#datagrid").datagrid({  
                singleSelect: true,  
                fitColumns: false,  
                border: false,  
                columns: [[  
                    {field: 'number', title: '编号', width: 66, editor: "text"},  
                    {field: 'pipingNo', title: '管道编号', width: 90, editor: "text"},  
                    {field: 'pipingName', title: '管道名称(登记单元)', width: 170, editor: "text"},  
                    {field: 'pipingLevel', title: '管道级别', width: 100, editor:{  
                         type: '<strong>combobox</strong>',  
                         options: {  
                            data: pipingLevel,  
                            valueField: "value",  
                            textField: "text",  
                            editable: false,  
                            panelHeight:70,  
                            required: true  
                        }  
                     }},  
                ]],  
</span>  
});

2.从远程获取数据，而后绑定到combobox中

columns: [[  
       {field: 'number', title: '编号', width: 100, editor:'text'},  
       {field: 'pipingNo', title: '管道编号', width: 100, editor: "text"},  
       {field: 'pipingName', title: '管道名称(登记单元)', width: 300, editor: "text"},    
       {field: 'DesignUnit', title: '设计单位', width: 300,editor:{  
             type:'combobox',  
             options:{  
                url: 'pressurePipingUnit/unit2',<span style="white-space:pre">        </span>//重远程加载数据  
               panelHeight: '200',  
               valueField:'unitId',<span style="white-space:pre">        </span>//保存到数据库的值  
               textField:'unitName',<span style="white-space:pre">   </span>//绑定到下拉列表框中显示的值  
            }  
       }},  
]],
