过滤器是否保留列表排序？(Does filter preserve list ordering?)

 你的按钮...... 
 
<button name="Login" type="button"  onclick="submitform();">Register</button>
 
 您不需要任何带有jQuery的内联JavaScript。 而你肯定不需要jQuery Validate插件的onclick处理程序。 
 
 将您的type更改为submit并删除内联点击处理程序... 
 
<button name="Login" type="submit">Register</button>
 
 
 你也不能把一个return false放到你的DOM就绪处理程序中...... 
 
$(document).ready(function () {

    $('#formreg').validate({
        // your rules
    });

    // return false;  // <- REMOVE THIS LINE

});
 
 
 工作演示： http ： //jsfiddle.net/M9Y6L/1/ 

Your button...
 
<button name="Login" type="button"  onclick="submitform();">Register</button>
 
You do not need any inline JavaScript with jQuery. And you certainly don't need an onclick handler for the jQuery Validate plugin.
 
Change your type into submit and remove the inline click handler...
 
<button name="Login" type="submit">Register</button>
 
 
You also cannot put a return false into your DOM ready handler...
 
$(document).ready(function () {

    $('#formreg').validate({
        // your rules
    });

    // return false;  // <- REMOVE THIS LINE

});
