我完全糊涂了......我发誓这昨天有效......我今天早上醒来，我的所有表格都停止在我的项目中工作.

I'm completely confused ... I'd swear this was working yesterday ... I woke up this morning and all my forms stopped to work in my project.

所有表单都有一个onsubmit"到一个返回 false 的函数，因为它是一个 ajax 调用，所以表单永远不会被发送.

All the forms have a "onsubmit" to a function that returns false since it's an ajax call, so the form is never sent.

经过大量测试，我将问题简化为这段代码:

After a lot of tests, I simplified the question to this piece of code:

<html> <head> <script type="text/javascript"> function sub() { alert ("MIC!"); return false; } </script> </head> <body> <form method = "post" id = "form1" onsubmit = "return sub()"> input: <input type="text" name="input1" > <a href="#" onClick="document.getElementById('form1').submit();">button</a> </form> </body> </html>

我发誓这很完美，但今天也不行:D

I would swear that this works perfectly, but today is nor working :D

为什么我按下按钮会发送表单?

Why if I press the button the form is sent ?

我知道这是一个新手问题，但我被卡住了

I know it's a total newbie question, but I'm stuck

谢谢！

推荐答案

如果您以编程方式调用 submit()，浏览器不调用表单上的 onSubmit 事件.

Browsers do not call the onSubmit event on the form if you call submit() programmatically.
