我花了一些时间制作这款跨浏览器，适用于IE8、9、10、Opera 9+、Firefox 23、Safari(PC)和Safari(MAC)

示例:http://jsfiddle.net/greatbigmassive/ZyeHe/

基本代码-通过“onkeypress”附加到您的窗体和传递窗口调用此函数。事件”。

function stopEnterSubmitting(e) {
    if (e.keyCode == 13) {
        var src = e.srcElement || e.target;
        if (src.tagName.toLowerCase() != "textarea") {
            if (e.preventDefault) {
                e.preventDefault();
            } else {
                e.returnValue = false;
            }
        }
    }
}

如果这些答案都不适合你，试试这个。在实际提交表单的按钮之前添加一个提交按钮，对事件什么都不做。

HTML

<!-- The following button is meant to do nothing. This button will catch the "enter" key press and stop it's propagation. -->
<button type="submit" id="EnterKeyIntercepter" style="cursor: auto; outline: transparent;"></button>

JavaScript

$('#EnterKeyIntercepter').click((event) => {
    event.preventDefault(); //The buck stops here.
    /*If you don't know what this if statement does, just delete it.*/
    if (process.env.NODE_ENV !== 'production') {
        console.log("The enter key was pressed and captured by the mighty Enter Key Inceptor (⌐■_■)");
    }
});

这个链接提供了一个在Chrome、FF和IE9以及IE7和ie8的模拟器(IE9的开发者工具(F12)中为我工作过的解决方案。

[2012修订版，没有内联处理程序，保留textarea进入处理]

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;
}

现在你可以在表单上定义一个按键处理程序: <形式[…onkeypress="return checkEnter(event)">

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

请查看这篇文章如何防止按ENTER键提交web表单?

$(“.pc_prevent_submit”)时函数(){ 美元(窗口).keydown(函数(事件){ 如果事件。keyCode == 13) { event.preventDefault (); 返回错误; ｝ })； })； < script src = " https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js " > < /脚本> <form class= " pc_prevent_submit " action= " " method= " post " > <input type= " text " name= " username " > <input type= " password " name= " userpassword " > <input type= " submit " value= " submit " > > < /形式

I Have come across this myself because I have multiple submit buttons with different 'name' values, so that when submitted they do different things on the same php file. The enter / return button breaks this as those values aren't submitted. So I was thinking, does the enter / return button activate the first submit button in the form? That way you could have a 'vanilla' submit button that is either hidden or has a 'name' value that returns the executing php file back to the page with the form in it. Or else a default (hidden) 'name' value that the keypress activates, and the submit buttons overwrite with their own 'name' values. Just a thought.
