如何用回调编写jQuery函数？ [英] How to write a jQuery function with a callback?

问题描述

我有以下功能：

function loadProjects(pID) {

    $.ajax({
        url: myURL,
        success: function (dataJS) {XXXXXXXXXXXXXXXX}
    });
}

我将此函数称为loadProjects（1）;

I call this function like so loadProjects(1);

问题是我希望能够在成功后定义一个callBack函数，并且我想在我执行loadProjects时包含它（1，回调：{此处包含的任何js被调用成功后回来}）

Issue is I want to be able to define a callBack function after success, and I'd like to include it when I do loadProjects(1, callback:{whatever js is included here gets called back after success})

我如何让函数接受回调？
如何将回调传递给该函数？

How can I have a function accept a callback? How can I pass a callback to that function?

谢谢

推荐答案

function loadProjects(pID, callbackFunction)
{
    $.ajax({
        url: myURL,
        success: function (dataJS)
        {
            if(typeof callbackFunction == 'function')
            {
                callbackFunction.call(this, dataJS);
            }
        }
    });
}

用法：

loadProjects(pID, function(dataJS)
{
    // do stuff with your dataJS, bear in mind you can call the parameter any name.
});
