问题描述
当我按下文本框上的回车键时如何防止表单自动提交？
解决方案< script type = text / jscript language = javascript > function submitButton（）{ if（window.event.keyCode == 0）{ return false; } else { return true; } } < / script >
你的按钮应该是这样的：
< form id =form1runat =serveronsubmit =return submitButton（）>如果这是正确的，则标记为答案。
< script type = text / javascript > function disableSubmitOnEnter（event）{ if（！event） event = window.event var keycode; if（event.which） keycode = event.which else var keycode = event.keyCode if（keycode == 13） return假; else返回true; } < / script >
< input type =textonkeydown =return disableSubmitOnEnter（事件）; />
