Extjs的grid的单元格中加载超链接和按钮

效果：

户型图列显示的图片实际上就是一个超链接。

添加一个Button分2个步骤：
1.在列头中定义超链接列或者Button列的HTML代码，也就是Render

2.添加该Button的事件处理函数。其中，gridPanel应作为参数传入该函数。

应该在gridPanel初始化时定义:
(1)cellClick的listener：cellClick
(2)cellClick事件的处理函数：onCellClick

列头定义的代码如下：

    var cm = new Ext.grid.ColumnModel([
		sm,
      new Ext.grid.RowNumberer(), //自动添加行号

         {
         header: "房间编号",
         dataIndex: "RoomNumber",
         //可以进行排序 
         sortable: true

     }, {
         header: "户型结构",
         dataIndex: "huxingjiegou",
         //可以进行排序
         isHidden: true,
         sortable: true

     }, {
         header: "面积(M²)",
         dataIndex: "area",
         //可以进行排序
         sortable: true

     }, {
         header: "单价(元/M²)",
         dataIndex: "singlePrice",
         //可以进行排序
         sortable: true
         //           editor: new Ext.grid.GridEditor(new Ext.form.NumberField({
         //            allowBlank: false
         //        }))

     }, {
         header: "总价(元)",
         dataIndex: "totalPrice",
         //可以进行排序
         sortable: true

     }, {
         header: "面积(M²)",
         dataIndex: "mianjiCC",
         //可以进行排序
         sortable: true

     }, {
         header: "单价(元/M²)",
         dataIndex: "priceCCS",
         //可以进行排序
         sortable: true
         //           editor: new Ext.grid.GridEditor(new Ext.form.NumberField({
         //            allowBlank: false
         //        }))

     }, {
         header: "总价(元)",
         dataIndex: "totalPriceCCS",
         //可以进行排序
         sortable: true

     }, {
         header: "面积(M²)",
         dataIndex: "mianjiCK",
         //可以进行排序
         sortable: true

     }, {
         //         header: "单价(元/M²)",
         header: "总价(元/M²)",
         dataIndex: "priceCK",
         //可以进行排序
         sortable: true
         //           editor: new Ext.grid.GridEditor(new Ext.form.NumberField({
         //            allowBlank: false
         //        }))

     },


      {
          header: "",
          dataIndex: "totalPriceALL",
          //可以进行排序
          sortable: true

      },
  {
      header: "户型图",
      tooltip: "户型图",

      width: 120,
      locked: true,
      menuDisabled: true,
      sortable: false,
      dataIndex: "huxingPic",
      renderer: function (data, metadata, record, rowIndex, columnIndex, store) {
          var picture = store.getAt(rowIndex).get('huxingPic');

          return '<a href="' + picture + '">' + '<img src="' + picture + '"width=60 hight=50> </a>';

      }
  },
     {
         header: "订购",

         renderer: function (value, meta, record) {

             var formatStr = "<button  onclick='javscript:return false;' class='order_bit'>订购</button>"; 
             var resultStr = String.format(formatStr);
             return "<div class='controlBtn'>" + resultStr + "</div>";
         } .createDelegate(this),
         css: "text-align:center;",
         //  width: 30,   
         sortable: false
     }

        ]);

注意超链接为'<a href="' + picture + '">'，而按钮为return "<div class='controlBtn'>"

按钮处理事件的代码如下：

//按钮点击事件
    grid.on('cellclick', function (grid, rowIndex, columnIndex, e) {
        var btn = e.getTarget('.controlBtn');
        var get = e.getTarget('.get');

        if (get) {
            var t = e.getTarget();
            record = grid.getStore().getAt(rowIndex);
            var control = t.className;
            row = grid.getSelectionModel().getSelected(); //得到选择所有行
            rowIndexId = rowIndex;
            this.GetRoomDetails(record, rowIndexId, projectName, loudongName); //传行一行记录直接加载
        }
        if (btn) {

            var t = e.getTarget();
            record = grid.getStore().getAt(rowIndex);
            var control = t.className;
            row = grid.getSelectionModel().getSelected(); //得到选择所有行
            switch (control) {

                 case 'sale_already':
                    {
                        var state = "已售";
                        //       this.SetSaleState(record,state)
                        this.GetOrderManagement(record, state, rowIndexId, projectName, loudongName)
                    }
                    break;
                case 'order_bit':
                    {
                        var state = "大定";
                        //       this.SetSaleState(record,state)  
                        this.GetOrderManagement(record, state, rowIndexId, projectName, loudongName)
                    }
                    break;
                   }
        }
    },
this);
};
