前台部分代码：

<div id='error'></div><!--错误提示信息--> 
 
<input type='text' id='username' name='username' readonly='Readonly'/><!--readonly为只读--> 
 
<input type='password' id='password' name='password'> 
<input type='text' id='company' name='company'> 
<input type='text' id='mobile' name='mobile'> 
<input type='text' id='email' name='email'> 
<button type='button' onclick='edit();'></button> 
 
<script> 
    function edit(){ 
        var password = $('#password').val(); 
        var company = $('#company').val(); 
 
        if(password == ''){ 
             $('error').show(); 
             $('error').html("密码不能为空!"); 
             return.false;
