Checking Jquery ajax load success
提问by Mark
I've been using thisto load another page, and just using their example :
我一直在用它来加载另一个页面，只是使用他们的例子：
$("#links").load("/Main_Page #jq-p-Getting-Started li");
However I want to run a function when the load is successful, and a different one if it fails, unfortunately the description on the callback says:
但是我想在加载成功时运行一个函数，如果失败则运行一个不同的函数，不幸的是回调的描述说：
The function called when the ajax request is complete (not necessarily success).
ajax请求完成时调用的函数（不一定成功）。
How do I make sure the load was successful?
如何确保加载成功？
Thanks.
谢谢。

You might try using the more detailed $.ajax() method call. This will give you more fine-grained control over the AJAX call (but it also requires a bit more work than a simple .load().) It will allow you to call different functions based on whether your call returns success or error.
您可以尝试使用更详细的 $.ajax() 方法调用。这将使您对 AJAX 调用进行更细粒度的控制（但它也需要比简单的 .load() 做更多的工作。）它将允许您根据调用返回成功还是错误来调用不同的函数。
Check out: http://docs.jquery.com/Ajax/jQuery.ajax#optionsfor documentation on this function. If you click the "Options" tab on that page, you will get a full listing of the parameters that you can pass to the $.ajax() function.
查看：http: //docs.jquery.com/Ajax/jQuery.ajax#options有关此功能的文档。如果单击该页面上的“选项”选项卡，您将获得可以传递给 $.ajax() 函数的参数的完整列表。

Check the textStatusof the response.
检查响应的textStatus。
$("#links").load("/Main_Page #jq-p-Getting-Started li",
function (responseText, textStatus, XMLHttpRequest) {
if (textStatus == "success") {
// all good!
}
if (textStatus == "error") {
// oh noes!
}
}

The second argument to your callback is the string status value for the request, which will be one of "beforeSend", "success", "complete", and "error".
第二个参数到您的回调是请求字符串状态值，这将是一个"beforeSend"，"success"，"complete"，和"error"。

I use this function and it worked for me:
我使用这个功能，它对我有用：
$.ajax({
url: "demo_test.txt",
success: function(result){
location:reload();
}
});
