我得到这个错误！ [函数外的'return'语句] [英] I get this error! [ 'return' statement outside of function ]

问题描述

我正在为一个客户端创建一个表单验证器，并在Internet Explorer(Explorer)7/8 ...中遇到了这个 only 奇怪的错误.

I was creating a form validator for a client and ran into this weird error only in Internet Explorer (Explorer) 7/8....

在函数第1行，字符1之外的'return'

'return' outside of function, line 1, char 1

当然，第1行没有任何代码.这是一条简单的注释语句.而且没有任何扭曲的方式.所以我知道这只是一个调试错误的方向.

Of course, there was no code whatsoever on line 1. It was a simple commented statement. And there was nothing wring with it in any way. So I knew it was just a debug misdirection.

我一直在拔头发，以了解这里可能出什么问题...

I have been pulling my hair out to understand what could be wrong here...

我已经排除了显而易见的情况:循环中的return语句，单个函数中的return语句太多，以及实际上在合法函数定义之外的所有return.

I have already ruled out the obvious: return statements in a loop, too many return statements in a single function, and any returns actually outside of a legitimate function definition.

这是什么原因?

推荐答案

问题是我正在使用return语句覆盖表单的默认行为，并将其分配给属性 but 它没有放在匿名函数中！

The problem was that I was using a return statement to override the default behavior for my form and it was assigned to a property, but it was not placed inside an anonymous function!

我有一个这样设置的表单元素:

I had a form element that was set up like this:

<form name="formname" onSubmit="javascript:validateForm(this);" action="javascript:return false;" method="post" enctype="multipart/form-data">

我需要更改的只是action属性:

All I needed to change was the action property to this:

… action="javascript:function(){return false};"

它现在可以完美地工作了！

It now works flawlessly!
