点击复制 ajax,jQuery：在ajax调用成功后返回数据[复制]

Hakam FostokFrancesco提出了一个问题：jQuery: Return data after ajax call success [duplicate]，或许与您遇到的问题类似。

回答者Guffa给出了该问题的处理方式：

The only way to return the data from the function would be to make a synchronous call instead of an asynchronous call, but that would freeze up the browser while it's waiting for the response.

You can pass in a callback function that handles the result:

function testAjax(handleData) {

$.ajax({

url:"getvalue.php",

success:function(data) {

handleData(data);

}

});

}

Call it like this:

testAjax(function(output){

// here you use the output

});

// Note: the call won't wait for the result,

// so it will continue with the code here while waiting.
