问题描述
我试图让使用jQuery 1.5.1与MVC3一个JSON响应和JavaScript是默默地崩溃了。调试服务器端code我绝对传递一个填充的列表来响应。
在问候评论一些进一步的信息。
在Firebug返回的响应是这样的:
[{LocationId:ASXX0413,LOCATIONNAME:阿尔巴尼,澳大利亚}]
和萤火虫也认识到它作为一个JSON对象。
我的javascript:
weatherEvents:功能(){ jQuery的(A#getweather)。点击(函数(事件){ 。事件preventDefault;
变种查询= jQuery的(#Farm_Weather)VAL(); 如果(查询===){
返回;
} jQuery.getJSON(/农场/天气,{位置:查询},功能(数据){
变种项= []; jQuery.each(数据,功能(键,VAL){
items.push(<立GT;+ val.LocationId +:+ val.LocationName +< /李>);
}); jQuery的(< UL />中,{
阶级:天气位置列表
HTML:items.join()
})appendTo(div.weatherdiv);
});
});
}
我的服务器端code:
[HTTPGET]
公共JsonResult天气(字符串位置)
{
字符串requestUrl =的String.Format(
http://xoap.weather.com/search/search?where={0},
HttpUtility.UrlEn code(location.Trim())); XmlDocument的xmlDoc中=新的XmlDocument();
XmlNodeList中节点列表= NULL; //将到Weather.com一个电话,搜索此位置
xmlDoc.Load(requestUrl);
节点列表= xmlDoc.SelectNodes(/搜索/ LOC); //把我们的节点列表,并得到一个新的匿名类型。
VAR jsonWeather = nodeList.Cast<&XmlElement的GT;()
。选择(X =>新建
{
LocationId = x.GetAttribute(ID),
LOCATIONNAME = x.InnerText
}); 返回JSON(jsonWeather.ToList(),JsonRequestBehavior.AllowGet);
}
答案事实证明它很简单......
有一个已知的错误使用jQuery 1.5.1和附带MVC的jquery.validate插件。
进一步信息可以在这里找到和更新的插件可以在这里找到 。
I'm trying to get a jSON response using jQuery 1.5.1 with mvc3 and the javascript is silently crashing out. Debugging the server side code i'm definitely passing a populated list to the response.
Some further information in regards to the comments.
The response returned in firebug is thus:
[{"LocationId":"ASXX0413","LocationName":"Albany, Australia"}]
and firebug also recognises it as a jSON object.
My Javascript:
weatherEvents: function () {
jQuery("a#getweather").click(function (event) {
event.preventDefault;
var query = jQuery("#Farm_Weather").val();
if (query === "") {
return;
}
jQuery.getJSON("/Farm/Weather", { location: query }, function (data) {
var items = [];
jQuery.each(data, function (key, val) {
items.push("<li>" + val.LocationId + " : " + val.LocationName + "</li>");
});
jQuery("<ul/>", {
"class": "weather-location-list",
html: items.join("")
}).appendTo("div.weatherdiv");
});
});
}
My server side code:
[HttpGet]
public JsonResult Weather(string location)
{
string requestUrl = string.Format(
"http://xoap.weather.com/search/search?where={0}",
HttpUtility.UrlEncode(location.Trim()));
XmlDocument xmlDoc = new XmlDocument();
XmlNodeList nodeList = null;
// Place a call to Weather.com and search for this location
xmlDoc.Load(requestUrl);
nodeList = xmlDoc.SelectNodes("/search/loc");
// Cast our nodelist and get a new anonymous type.
var jsonWeather = nodeList.Cast<XmlElement>()
.Select(x => new
{
LocationId = x.GetAttribute("id"),
LocationName = x.InnerText
});
return Json(jsonWeather.ToList(), JsonRequestBehavior.AllowGet);
}
The answer it turns out it quite simple.....
There is a known bug with jQuery 1.5.1 and the jquery.validate plugin shipped with mvc.
further info can be found here and the updated plugin can be found here.
