How to get request url in a jQuery $.get/ajax request
提问by Christopher
I have the following code:
我有以下代码：
$.get('http://www.example.org', {a:1,b:2,c:3}, function(xml) {}, 'xml');
Is there a way to fetch the url used to make the request after the request has been made (in the callback or otherwise)?
有没有办法在发出请求后（在回调中或以其他方式）获取用于发出请求的 url？
I want the output:
我想要输出：
http://www.example.org?a=1&b=2&c=3

I can't get it to work on $.get()because it has no completeevent.
我无法让它工作，$.get()因为它没有complete事件。
I suggest to use $.ajax()like this,
我建议这样使用$.ajax()，
$.ajax({
url: 'http://www.example.org',
data: {'a':1,'b':2,'c':3},
dataType: 'xml',
complete : function(){
alert(this.url)
},
success: function(xml){
}
});

Since jQuery.get is just a shorthand for jQuery.ajax, another way would be to use the latter one's contextoption, as stated in the documentation:
由于 jQuery.get 只是 jQuery.ajax 的简写，另一种方法是使用后者的context选项，如文档中所述：
The
thisreference within all callbacks is the object in the context option passed to$.ajaxin the settings; if context is not specified, this is a reference to the Ajax settings themselves.
this所有回调中的引用是传递给$.ajax设置中的上下文选项中的对象；如果未指定上下文，则这是对 Ajax 设置本身的引用。
So you would use
所以你会使用
$.ajax('http://www.example.org', {
dataType: 'xml',
data: {'a':1,'b':2,'c':3},
context: {
url: 'http://www.example.org'
}
}).done(function(xml) {alert(this.url});
