我正在开发一个国家级联下拉列表...我根据 countryId 返回了 JSON 结果，但我不知道如何将其填充/填充到新的下拉列表框中...
这是我正在使用的，
function getstate(countryId) {
$.ajax({
type: "POST",
url: "Reg_Form.aspx/Getstates",
data: "{'countryId':" + (countryId) + "}",
contentType: "application/json; charset=utf-8",
global: false,
async: false,
dataType: "json",
success: function(jsonObj) {
alert(jsonObj.d);
}
});
return false;
}
alert 给出了这个，
{"Table" : [{"stateid" : "2","statename" : "Tamilnadu"},
{"stateid" : "3","statename" : "Karnataka"},
{"stateid" : "4","statename" : "Andaman and Nicobar"},
{"stateid" : "5","statename" : "Andhra Pradesh"},
{"stateid" : "6","statename" : "Arunachal Pradesh"}]}
我的 aspx 页面有这个，
<td>
<asp:DropDownList ID="DLCountry" runat="server" CssClass="dropDownListSkin"
onchange="return getstate(this.value);">
</asp:DropDownList>
</td>
<td>
<asp:DropDownList ID="DLState" runat="server" CssClass="dropDownListSkin">
</asp:DropDownList>
</td>
关于如何填写 DLState 下拉列表的任何建议...
编辑:
当我通过 firebug 检查时，我收到了我的 AJAX 帖子的响应，
{"d":"{\"Table\" : [{\"stateid\" : \"2\",\"statename\" : \"Tamilnadu\"},{\"stateid\" : \"3\",\"statename\" : \"Karnataka\"},{\"stateid\" : \"4\",\"statename\" : \"Andaman and Nicobar\"},{\"stateid\" : \"5\",\"statename\" : \"Andhra Pradesh\"},{\"stateid\" : \"6\",\"statename\" : \"Arunachal Pradesh\"},{\"stateid\" : \"7\",\"statename\" : \"Assam\"},{\"stateid\" : \"8\",\"statename\" : \"Bihar\"},{\"stateid\" : \"9\",\"statename\" : \"Dadra and N.

最佳答案
var listItems= "";
var jsonData = jsonObj.d;
for (var i = 0; i < jsonData.Table.length; i++){
listItems+= "<option value='" + jsonData.Table[i].stateid + "'>" + jsonData.Table[i].statename + "</option>";
}
$("#<%=DLState.ClientID%>").html(listItems);
示例
<html>
<head></head>
<body>
<select id="DLState">
</select>
</body>
</html>
/*javascript*/
var jsonList = {"Table" : [{"stateid" : "2","statename" : "Tamilnadu"},
{"stateid" : "3","statename" : "Karnataka"},
{"stateid" : "4","statename" : "Andaman and Nicobar"},
{"stateid" : "5","statename" : "Andhra Pradesh"},
{"stateid" : "6","statename" : "Arunachal Pradesh"}]}
$(document).ready(function(){
var listItems= "";
for (var i = 0; i < jsonList.Table.length; i++){
listItems+= "<option value='" + jsonList.Table[i].stateid + "'>" + jsonList.Table[i].statename + "</option>";
}
$("#DLState").html(listItems);
});
