防止在按Enter键时提交表单
我们如何防止在按Enter键的同时提交表单.
how can we prevent a form from being submitted while pressing enter key.
实际上，我有一个文本框，在该文本框上输入一个值并单击Enter时，textbox2将变得集中.
Actually I have a text box and on entering a value on that textbox and clicking enter the textbox2 will get focused.
默认情况下，单击输入按钮将提交表单.因此我无法解决问题.我在提交按钮的onclick事件上写了return false，然后它起作用了. 因此，我想知道如何在按Enter键时阻止表单提交.
By default on clicking the enter button the form will get submitted. So I can not get the out put. I wrote return false on onclick event of the submit button then it works. So I would like to know how can we prevent a form submission while pressing enter.
在不查找实际代码的情况下，这是我要怎么做的基本原理:
Without looking up the actual code, here's the basic theory behind how I'd do it:
在文档上定义一个事件处理程序，以按下一个键来调用函数.
Define an event handler on the document for a key being pressed to call a function.
如果触发事件的键是回车键，则为return false，否则为return true.
If the key that triggered the event is the enter/return key, return false, otherwise return true.
看来您已经找到了答案(以及执行此操作的一些代码)，所以现在我的答案有些不必要了.
Looks like you already found the answer (as well as some code to do it), so my answer is somewhat unnecessary now.
