為了省事很多時候希望可以按斷行符號鍵來提交表單，要控制這些行為，可以藉助JS來達到要求。
代碼如下：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ include file="../../common/include_tag.jsp"%><%@ include file="../../common/page_var.jsp"%><!DOCTYPE HTML><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title><%=pageTitle%>-使用者登入</title><%@ include file="../../common/page_head.jsp"%><link rel="stylesheet" type="text/css" href="<s:url value='/css/common_green.css'/>" /><script type="text/javascript" src="<s:url value='/js/jquery.min.js'/>"></script><script type="text/javascript" src="<s:url value='/js/common.js'/>"></script><style type="text/css">.logo{ padding-top: 20px; padding-left: 20px; padding-right: 20px; padding-bottom: 20px; font-size: 28px;}.top{ padding-bottom: 100px;}.login{ line-height: 32px;}.content { width: 350px; margin: 15px auto auto; padding: 50px 50px; border: 2px solid #ccc; border-radius: 10px; box-shadow: 0 0 30px #ccc;}.bottom{ padding-top: 100px;}.button{ margin-top: 10px; margin-left: 105px;}.update { margin: 0 auto; padding: 0; width: 98%;}.update td { margin: 0; height: 30px; padding: 5px;}.update .name { text-align: right;}.title_div { width: 350px;}body { background: url("< s : url value = '/images/gray_bg.png'/ >") 0 0 repeat-y #F6F6F6;}</style><script type="text/javascript"> $(function() { pilicat.title2div('title2div'); pilicat.keysubmit('form1', 'submit', true); });</script></head><body> <div class="logo">首都機場空地自動化協同決策系統</div> <div class="rounded table"> <div class="top"></div> <div class="content"> <form id="form1" action="<s:url value='/u/ulogin'/>" method="post"> <div align="center"><span style="color: red;">${captcha}</span></div> <table class="table table-bordered table-striped" style="width: 310px; padding-left: 50px;"> <tbody> <tr class="login"> <td><span>賬 號: </span></td> <td><input type="text" id="userName" name="userName" class="input rounded" value="" placeholder="帳號" /></td> </tr> <tr class="login"> <td><span>密 碼: </span></td> <td><input type="password" id="passWd" name="passWd" class="input rounded" value="" placeholder="密碼" /></td> </tr> <tr class="login"> <td><span>驗證碼: </span></td> <td><input type="text" id="captcha" name="captcha" size="5" maxlength="5" class="input rounded" value="" placeholder="驗證碼" /> <img id="captcha" style="cursor: pointer; cursor: hand; margin-top: -5px; margin-right: -10px;" align="middle" onclick="this.src='<s:url value='/u/captcha.htm'/>?'+Math.random();" src="<s:url value='/u/captcha.htm'/>"> </td> </tr> <tr class="login"> <td colspan="2"> <a id="submit" class="submit" href="javascript:;" onclick="submitForm();">登入</a> </td> </tr> </tbody> </table> </form> </div> <div class="bottom"></div> </div> <%@ include file="../../common/bottom.jsp"%></body></html>
解決方案：
把form表單放在一個div裡面 ，然後對這個div監聽事件$("#id").keydown(function (){});
#*#監聽斷行符號事件
document.onkeydown=function() {if(event.keyCode==13) {//這裡提交你的表單$('#ff_login').submit();}}
#*#頁面編寫js指令碼進行監聽。。。
#*#js監聽enter事件#*#
把form表單放在一個div裡面 ，然後對這個div監聽事件$("#id").keydown(function (){});
#*#擷取焦點 監聽enter#*#
監聽整個body的keypress事件，如果是斷行符號鍵，激發submit按鈕的click事件，當然你的click事件中會有相關的資料驗證之類的，如果驗證不過，不會提交。
