问题
how can we prevent a form from being submitted while pressing enter key.
Actually I have a text box and on entering a value on that textbox and clicking enter the textbox2 will get focused.
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.
回答1:
Without looking up the actual code, here's the basic theory behind how I'd do it:
Define an event handler on the document for a key being pressed to call a function.
If the key that triggered the event is the enter/return key, return false, otherwise return true.
EDIT: Looks like you already found the answer (as well as some code to do it), so my answer is somewhat unnecessary now.
回答2:
Writing 'onKeyPress' of the form like " { var key; if(window.event) key = window.event.keyCode; else key = e.which; //firefox return (key != 13); } " will work.
回答3:
what i do is add onsubmit="return false;" to the <form> tag.
this will also disable the submit button however to create a working submit button use
<input type="button" value="Submit" onclick="javascript:document.form.submit();" />

This should work
<form onsubmit="return false;">
//Form elements
</form>
