JQuery.validate在ie8下不支持解决方案

一、在ie8下回有问题的代码

1、JQuery.validate验证框架是通过页面form表单提交验证标签中输入是否符合自己的规则的

html代码

其中 name属性和下面js中的rules中的属性一致

2、js绑定validate事件代码如下

<span style="color: #008080;"> 1</span> $(<span style="color: #0000ff;">function</span><span style="color: #000000;">() {
</span><span style="color: #008080;"> 2</span> <span style="color: #000000;">           initCardTypeFrmValidate()
</span><span style="color: #008080;"> 3</span> <span style="color: #000000;">           })
</span><span style="color: #008080;"> 4</span> 
<span style="color: #008080;"> 5</span> <span style="color: #0000ff;">function</span><span style="color: #000000;"> initCardTypeFrmValidate() {
</span><span style="color: #008080;"> 6</span> 
<span style="color: #008080;"> 7</span>     $('#cardTypeFrm'<span style="color: #000000;">).validate({

</span><span style="color: #008080;"> 9</span>         onfocusout : <span style="color: #0000ff;">false</span><span style="color: #000000;">,
</span><span style="color: #008080;">10</span> <span style="color: #000000;">        rules : {

</span><span style="color: #008080;">13</span> <span style="color: #000000;">        },
</span><span style="color: #008080;">14</span>

</span><span style="color: #008080;">18</span> <span style="color: #000000;">        },
</span><span style="color: #008080;">19</span>         errorElement : "p"
<span style="color: #008080;">20</span> <span style="color: #000000;">    });
</span><span style="color: #008080;">21</span> }

js代码

onkeyup : false,表示键盘输入不验证，默认true
onfocusout : false,表示输入框失去焦点不验证，默认true

二、解决方案是，禁止页面的表单提交，实行js中绑定表单提交表单

1、html代码不变
