问题描述
- 为什么onsubmit在审核地址的时候就失效了呢？
-
其他的账号密码都可以拦住，但是地址不管有没有选，只要提交就可以跳到servlet，而且只要账号密码都填了，就算onsubmit里面check函数全部设置为return false 一样可以跳<head> <base href="<%=basePath%>"> <title>用户注册</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> <script language="javascript" src="checkForm.js"></script> <script language="javascript" type="text/javascript" src="<%=basePath%>/js/My97DatePicker/WdatePicker.js"></script> <!-- 二级联动下拉框 --> <script language="JavaScript" type="text/javascript"> var city=[ ["北京","天津","上海","重庆"], ["南京市","苏州市","南通市","常州市"], ["福州市","福安市","龙岩市","南平市"], ["广州市","潮阳市","潮州市","澄海市"], ["兰州市","白银市","定西市","敦煌市"] ]; function getCity(){ var sltProvince=document.userform.province; var sltCity=document.userform.city; var provinceCity=city[sltProvince.selectedIndex - 1]; sltCity.length=1; for(var i=0;i< provinceCity.length;i++){ sltCity[i+1]=new Option(provinceCity[i],provinceCity[i]); } } </script> </head> <body> <form name="userform" action="servlet/AddUserServlet" method="post" onsubmit="return check()"> <table align="center" border="1" width="440px"> <tr> <td colspan="2" align="center" >用户注册表</td> </tr> <tr> <td align="center">用户姓名</td> <td> <input type="text" name="uname" size="" onblur="checkUname(this.value)"> <span id="unameErr"></span> </td> </tr> <tr> <td align="center">用户密码</td> <td> <input type="password" name="upwd" onblur="checkUpwd(this.value)"> <span id="upwdErr"></span> </td> </tr> <tr> <td align="center">确认密码</td> <td> <input type="password" name="upwd2" onblur="checkUpwd2(this.value)"> <span id="upwd2Err"></span> </td> </tr> <tr> <td align="center">用户性别</td> <td> <input type="radio" name="usex" value="男" checked>男 <input type="radio" name="usex" value="女">女 </td> </tr> <tr> <td align="center">出生日期</td> <td> <input name="strbirth" class="Wdate" type="text" id="d16" onfocus="WdatePicker({position:{right:100,top:50}})"/> </td> </tr> <tr> <td align="center">用户住址</td> <td> <SELECT NAME="province" onChange="getCity()" onblur="checkUaddr(this.value)"> <OPTION VALUE="">请选择所在省份</OPTION> <OPTION VALUE="直辖市">直辖市</OPTION> <OPTION VALUE="江苏省">江苏省</OPTION> <OPTION VALUE="福建省">福建省</OPTION> <OPTION VALUE="广东省">广东省</OPTION> <OPTION VALUE="甘肃省">甘肃省</OPTION> </SELECT> <SELECT NAME="city" onblur="checkUaddr(this.value)"> <OPTION VALUE="">请选择所在城市</OPTION> </SELECT> <span id="uaddrErr"></span> </td> </tr> <tr><td colspan="2" align="center"> <input type="submit" value="确定" style="width: 82px; "> <input type="reset" value="重置" style="width: 82px; "> </td></tr> </table>这是checkForm.js function check() { if(!checkUname(document.userform.uname.value)){ return false; }else if(!checkUpwd(document.userform.upwd.value)){ return false; }else if(!checkUpwd2(document.userform.upwd2.value)){ return false; }else if(!checkUaddr(document.userform.province.value)){ return false; }else if(!checkUaddr(document.userform.city.value)){ return false; }else { return true; }}

解决方案
你的checkUaddr函数没有啊。发代码的时候用</>格式化一下就好了
解决方案二：
按钮的监听事件是不是没有添加啊？
