取名好难啊啊啊啊啊_ 2013-04-23 07:42:53

废话不多说直接上代码：
HTML:
<div data-role="fieldcontain">
<fieldset data-role="controlgroup" data-type="horizontal" data-mini="true">
<legend>请选择所在省市</legend>
<label for="province">请选择省份</label>
<select name="province" id="province" onchange="findCity(this);">
<option value="">请选择省份</option>
</select>
<label for="city">请选择城市</label>
<select name="city" id="city">
<option value="">请选择城市</option>
</select>
</fieldset>
</div>
js
//页面加载时，查询出所有省份
$.ajax({
type:"post",
url:"<%=request.getContextPath() %>/mpcustom/findprovince.mobile",
success:function(html){
var select = $("#province");
var allProArr = html.split(";");
for ( var i = 0; i < allProArr.length; i++) {
var siglePro = allProArr[i].split(",");
$("<option value='"+siglePro[0]+"'>" + siglePro[1] + "</option>").appendTo(select);
}
}
});
//页面加载时，若是已注册用户，则选好省市
var provId = "${custom.province}";
var cityId = "${custom.city}";
var select_pro = $("#province");
var select_city = $("#city");
//alert(provId) ;
select_pro.val(provId);
select_pro.selectmenu("refresh",true);
select_city.val(cityId);
select_city.selectmenu("refresh");

省市都赋值不上。去掉alert的注释，在火狐上则能显示出省。还请大神出马！！！
