用JSON响应失意 [英] Frustrated with Json Response
问题描述
因此,这里是我的问题。我使用jQuery的$就以一系列的值传递回一个Web方法。 Web方法所采用的值,创建一个对象,然后将其发送回作为JSON来调用页面。一旦我得到的回应回到我无法访问响应并显示它的值。
任何人能解释什么,我需要做的,使这项工作?
jQuery的脚本:
$(文件)。就绪(函数(){
$(#创建)。点击(函数(){
变种名称= $('#姓名)VAL()。
VAR公司= $('#公司)VAL()。
。VAR位置= $('#位置)VAL();
VAR PHONENUMBER = $('#PHONENUMBER)VAL()。
。VAR国家= $('#国)VAL(); $阿贾克斯({
键入:POST,
网址:WebService.asmx / MakeEmployee
数据:{名称:'+姓名+
',公司本着:'+公司+
',位置:+位置+
',电话号码:'+ PHONENUMBER +
'国家:'+国家+
'},
的contentType:应用/ JSON的;字符集= UTF-8,
数据类型:JSON
成功:函数(MSG){
AjaxSucceeded(msg.d);
}
});
}); 功能AjaxSucceeded(数据){
// VAR项目= jQuery.parseJSON(数据)//这不会为我工作。
$(#反应)。HTML(
< UL><立GT;+ data.Name +
< /李><立GT;+ data.Company +
< /李><立GT;+ data.Address +
< /李><立GT;+ data.Phone +
< /李><立GT;+ data.Country +
&所述; / UL>中
);
};
});
Web方法:
[的WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)
公共字符串MakeEmployee(字符串名称,字符串的公司,
字符串位置,字符串phoneNumber的,串国家)
{
员工E =新员工(姓名,公司,地点,phoneNumber的,国家);
返回新的JavaScriptSerializer()序列化(E)。
}
和响应说我找回:
{D:\\名称\\:\\鲍勃\\,
\\公司\\:\\谷歌\\,
\\地址\\:\\家\\,
\\电话\\:\\123 \\,
\\国家\\:\\美国\\}
这是什么,我认为我应该得到回:
{名:鲍勃,
公司:谷歌,
地址:家,
手机:123,
国:USA}
我得到一次页面错误再次渲染是这样的:
•未定义
•未定义
•未定义
•未定义
•未定义
您回应就已经被解析为JSON,因此它已经是一个对象......没有必要再分析它只是用它直接,就像这样:
函数AjaxSucceeded(数据){
$(#反应)。HTML(
< UL><立GT;+ data.Name +
< /李><立GT;+ data.Company +
< /李><立GT;+ data.Address +
< /李><立GT;+ data.Phone +
< /李><立GT;+ data.Country +
&所述; / UL>中
);
}
的 {D:...}
包装是由ASP.Net增加,这是正常的行为。之后,您的问题没有正确的返回元素,你需要返回的对象的不是的字符串从ASP.Net,$ P $ 的pferably这样的:
[的WebMethod,ScriptMethod(ResponseFormat = ResponseFormat.Json)
公务员MakeEmployee(字符串名称,字符串的公司,
字符串位置,字符串phoneNumber的,串国家){
返回新员工(姓名,公司,地点,phoneNumber的,国家);
}
...其中员工
有你想要的JavaScript端的属性。让ASP.Net在这里处理序列,而不是直接做它,你会得到一个更清洁响应的整体。
So here is my problem. I'm using Jquery's $.ajax to pass back a series of values to a web method. The web method takes the values, creates an object and then sends it back as json to the calling page. Once I get the response back I am unable to access the response and display it's values.
Can anyone explain what I need to do to make this work?
The jquery script:
$(document).ready(function() {
$("#create").click(function() {
var name = $('#name').val();
var company = $('#company').val();
var location = $('#location').val();
var phonenumber = $('#phonenumber').val();
var country = $('#country').val();
$.ajax({
type: "POST",
url: "WebService.asmx/MakeEmployee",
data: "{name:'" + name +
"',company:'" + company +
"',location:'" + location +
"',phonenumber:'" + phonenumber +
"',country:'" + country +
"'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
AjaxSucceeded(msg.d);
}
});
});
function AjaxSucceeded(data) {
//var item = jQuery.parseJSON(data) // this doesn't work for me.
$("#response").html(
"<ul><li> " + data.Name +
"</li><li> " + data.Company +
"</li><li> " + data.Address +
"</li><li> " + data.Phone +
"</li><li> " + data.Country +
"</ul> "
);
};
});
The web method:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string MakeEmployee(string name, string company,
string location, string phoneNumber, string country)
{
Employee e = new Employee(name, company, location, phoneNumber, country);
return new JavaScriptSerializer().Serialize(e);
}
And the response that I'm getting back:
{"d":"\"Name\":\"bob\",
\"Company\":\"google\",
\"Address\":\"home\",
\"Phone\":\"123\",
\"Country\":\"usa\"}"}
This is what I think I should be getting back:
{"Name":"bob",
"Company":"google",
"Address":"home",
"Phone":"123",
"Country":"usa"}
The error I get once the pages renders again is this:
•undefined
•undefined
•undefined
•undefined
•undefined
Your response will already be parsed as JSON, so it's already an object...no need to parse it again just use it directly, like this:
function AjaxSucceeded(data) {
$("#response").html(
"<ul><li> " + data.Name +
"</li><li> " + data.Company +
"</li><li> " + data.Address +
"</li><li> " + data.Phone +
"</li><li> " + data.Country +
"</ul> "
);
}
The { d: ... }
wrapper is added by ASP.Net, that's normal behavior. After that your issue is the element not returned correctly, you need to return an object not a string from ASP.Net, preferably this:
[WebMethod, ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public Employee MakeEmployee(string name, string company,
string location, string phoneNumber, string country) {
return new Employee(name, company, location, phoneNumber, country);
}
...where Employee
has the properties you want on the JavaScript side. Let ASP.Net handle the serialization here instead of doing it directly, you'll get a cleaner response overall.
