js循环给checkbox赋值？

Question

想根据取到的数组的值，选取checkbox控制其选中

 for(var i=0;i<codeArr.length;i++){

   var tem = codeArr[i];

            alert(tem);

           **$("input:checkbox[value='"+tem+"']").attr("checked","checked");**

        }

现在的效果是实际上只有与数组第一个元素匹配的checkbox被选中

试了下，没问题啊？<input type="checkbox" value="0"/><input type="checkbox" value="1"/><input type="checkbox" value="2"/><input type="checkbox" value="3"/><input type="checkbox" value="4"/><input type="checkbox" value="5"/><script>&nbsp; &nbsp; var codeArr = [0,3,5];&nbsp; &nbsp; for(var i=0;i<codeArr.length;i++){&nbsp; &nbsp; &nbsp; &nbsp; var tem = codeArr[i];&nbsp; &nbsp; &nbsp; &nbsp; $("input:checkbox[value='"+tem+"']").attr("checked","checked");&nbsp; &nbsp; }</script>
