如何给
<select name="ddlProvince" id="ddlProvince">
</select>
赋值

Answer 1

1、先判断返回的json数据的格式。

2、然后用jquery将值取出并拼接成字符串。

3、插入到html对象中。

下面是具体的实现过程：

<select id="select"></select>
<script type="text/javascript">
html= "";
str = {"prolist":['安徽','北京']};//josn对象.
$.each(str.prolist,function(a,b){//直接取出json的prolist做each循环.
html += "<option>"+b+"</option>";//拼接字符串.
});
$("#select").html(html);//将拼接好的字符串插入到id为select的 select对象中.
</script>

Answer 2

var arr = jsonObj.provlist; // jsonObj 是你的json对象
$.each(arr, function(i, txt){
$("#ddlProvince").append("<option value='"+txt+"'>"+txt+"</option>");
});
