问题描述

我有一个返回值的函数，我在点击事件后执行了该函数，例如

I have a function that return value and i executed the function after click event for example

$("some_div").click( my_function());

答案是如何获得函数的返回值。

The answer is how to get the returned value of the function.

推荐答案

你必须将函数传递给点击，而不是返回值。在事件处理程序中，您可以调用您的函数并按您认为合适的方式处理返回值：

You have to pass a function to click, not its return value. In the event handler you can call your function and deal with the return value as you see fit:

$("some_div").click(function() {
    var result = my_function();
    // do whatever you want with `result`
});

事件处理程序不会立即调用，但会在稍后（单击元素时）调用。因此， .click 返回一个值是没有意义的。

The event handler is not called immediately, but some time later (when the element is clicked). Therefore it does not make sense for .click to return a value.
