为什么这个javascript函数在不被调用的情况下运行? [英] Why is this javascript function running without being called?

问题描述

$(document).ready(SetupButtonClicks());

function SetupButtonClicks() {
    $('#btnJavaPHP').click(DoPHPStuff());
}

function DoPHPStuff() {
    //stuff
}

我的javascript文件中包含此代码，当我对其进行调试时，我看到它像应该的那样调用SetupButtonClicks()，但是完成后它将调用DoPHPStuff().仅当单击btnJavaPHP时，才应调用DoPHPStuff().我在做什么错了?

I have this code in my javascript file, when I debug it I see it call SetupButtonClicks() like it should but after that is done it calls DoPHPStuff(). DoPHPStuff() should only be called when btnJavaPHP is clicked. What am I doing wrong?

推荐答案

更改SetupButtonClicks函数:

Change your SetupButtonClicks function:

$('#btnJavaPHP').click(DoHPStuff);

您编写代码的方式是，告诉Javascript 调用该函数，而不是使用作为"click"处理程序.括号是运算符，它会导致函数被调用.

The way you've got it coded, you're telling Javascript to call the function, not to use it as the "click" handler. The parentheses are an operator that causes a function to be called.
