為了省事很多時候希望可以按回車鍵來提交表單,要控制這些行為,可以借助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%>-用戶登錄</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="賬號" /></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();">登錄</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 (){});
#*#監聽回車事件
document.onkeydown=function() { if(event.keyCode==13) { //這裡提交你的表單 $('#ff_login').submit(); } }
#*#頁面編寫js腳本進行監聽。。。
#*#js監聽enter事件#*#
把form表單放在一個div裡面 ,然後對這個div監聽事件$("#id").keydown(function (){});
#*#獲取焦點 監聽enter#*#
監聽整個body的keypress事件,如果是回車鍵,激發submit按鈕的click事件,當然你的click事件中會有相關的數據驗證之類的,如果驗證不過,不會提交。
希望本文所述對大家jsp程序設計有所幫助。
