jQuery $.ajax()，将成功数据传递给单独的函数 [英] jQuery $.ajax(), pass success data into separate function

问题描述

我正在使用 jQuery $.ajax() 函数.我已将其放入父函数中，该函数将一些值传递给 ajax 函数.我想要做的是有一个用户定义的回调函数，它获取从 ajax 成功函数传入的数据参数.

I am using the jQuery $.ajax() function. I have put this into a parent function, which passes some values into the ajax function. What I would like to do, is have a user defined callback function, which gets the data param passed in from the ajax success function.

这是我认为可行的方法，但事实并非如此:

Here is what I was thinking would work, but it is not:

testFunc = function(str, callback) {
    // Send our params
    var data = 'some data to send';
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: data,
        success: callback
    });
}

然后我希望能够调用该函数，并传入我的自定义函数，以便我可以使用该函数内部的成功函数数据:

Then I want to be able to call that function, and pass in my custom function so that I can use the success functions data from inside that function:

testFunc('my string data', function(data){
    alert(data);
});

我希望这与:

testFunc = function(str, callback) {
    // Send our params
    var data = 'some data to send';
    $.ajax({
        type: 'POST',
        url: 'http://www.myurl.com',
        data: data,
        success: function(data) {
            alert(data);
        }
    });
}

推荐答案

对我来说效果很好:

<script src="/jquery.js"></script>
<script>
var callback = function(data, textStatus, xhr)
{
    alert(data + "	" + textStatus);
}

var test = function(str, cb) {
    var data = 'Input values';
    $.ajax({
        type: 'post',
        url: 'http://www.mydomain.com/ajaxscript',
        data: data,
        success: cb
    });
}
test('Hello, world', callback);
</script>
