Ext中复选框显示不出来

Question

如图：代码如下：<script type="text/javascript">
Ext.onReady(function(){
var sm = new Ext.grid.CheckboxSelectionModel({handleMouseDown:Ext.emptyFn});//复选框
//列模型
var cm = new Ext.grid.ColumnModel([
                                   new Ext.grid.RowNumberer(),//自动生成行号
                                   sm,
                                   {header:"编号",dataIndex:"id",sortable:true},
                                   {header:"姓名",dataIndex:"name"},
                                   {header:"性别",dataIndex:"sex",renderer:function(value){
                                   if(value=='male'){
                                   return "<span style='color:red;font-weight:bold'>红男</span><img src='image/user_male.png'/>";
                                   } 
                                   else
                                   {
                                   return "<span style='color:green;font-weight:bold'>绿女</span><img src='image/user_fmale.png'/>";
                                   }
                                   }},
                                   {id:"descn",header:"描述",dataIndex:"descn"},
                                   {header:"日期",dataIndex:"date",type:'date',renderer:Ext.util.Format.dateRenderer('Y年m月d日')}]);
var data=[['1','啊','male','descn1','1970-01-15T02:58:04'],
          ['2','啵','fmale','descn2','1970-01-15T02:58:04'],
          ['3','簎','fmale','descn3','1970-01-15T02:58:04'],
          ['4','德','male','descn4','2011-03-15T02:58:04'],
          ['5','咯','male','descn5','2011-05-15T02:58:04']];


var ds = new Ext.data.Store({
proxy:new Ext.data.MemoryProxy(data),
reader:new Ext.data.ArrayReader({},[{name:'id'},
                                    {name:'name'},
                                    {name:'sex'},
                                    {name:'descn'},
                                    {name:'date',type:'date',dateFormat:'Y-m-dTh:i:s'}]),
sortInfo:{field:'name',direction:'ASC'}
});
ds.load();//加载数据
var grid = new Ext.grid.GridPanel({
el:'grid',
ds:ds,
cm:cm,
sm:sm
//autoExpandColumn:'descn'
});
Ext.get('remove').on('click',function(){
ds.remove(ds.getAt(1));
grid.view.refresh();
});
grid.render();//渲染
});

//alert(Ext.get('remove'));

</script>
代码有点长，不过，挑重点的看就行！主要就是复选框没有显示出来，不知道啥原因！

Answer 1

var data=[['1','啊','male','descn1','1970-01-15T02:58:04'],
依稀记得store的data格式好像是[{},{},{}...]
难道是别的写法？

Answer 2

var myData={"list":[    
    {"id":"1","title":"1","code":"222","address":"333","uname":"444","time":"2010年10月29日 17:15"},  
    {"id":"2","title":"2","code":"333","address":"444","uname":"555","time":"2010年10月29日 17:15"}
            ]} 
            
    var ds = new Ext.data.Store({
    reader: new Ext.data.JsonReader({root: 'list'},
     [{name:'id'},{name:'title'},{name:'code'},{name:'address'},{name:'uname'},{name:'time'}])
});
    ds.loadData(myData);
我一般用制定root的方式读json
你用数组， reader:new Ext.data.ArrayReader({这里是不是要加上一个data},随便看了下，懒得试了。

Answer 3

  var sm = new Ext.grid.CheckboxSelectionModel();

Answer 4

grid的数据 能看到吗？ 只是没有复选框？

Answer 5

可能是你缺少 或者改变了 ext默认的 样式吧只要在grid中 引入 sm 肯定是可以显示的

Answer 6

而且我还有一个问题就是ext在分页的时候，只是文字信息，没有图片，不知道是不是也跟这个样式有关系？

Answer 7

你意思 上一页 下一页 和刷新的图片 都没有？  要不然就是样式 要不然就是ext资源的图片路径没引用对路径

Answer 8

刚刚去下了个ext2.0，把那个resource目录全部放到工程下面，就全部可以了，谢谢zn85600301的回复。
