[ revision 2012, no inline handler, preserve textarea enter handling]

([2012年修订版 ，没有内联处理程序，保留textarea输入处理内容])

function checkEnter(e){
 e = e || event;
 var txtArea = /textarea/i.test((e.target || e.srcElement).tagName);
 return txtArea || (e.keyCode || e.which || e.charCode || 0) !== 13;
}

Now you can define a keypress handler on the form:

(现在，您可以在表单上定义按键处理程序：)

<form [...] onkeypress="return checkEnter(event)">

( <form [...] onkeypress =“ return checkEnter（event）”> )

document.querySelector('form').onkeypress = checkEnter;
