使用js对form表单base64加密

 姓名：<input type="text" id="name"  ><br/>
 密码：<input type="password" id="password" ><br/>
<button onclick="submitData()">提交</button>

<script>
    function submitData(){
        
        var obj = new Object();
        obj.name = $(‘#name‘).val();
        obj.password= $(‘#password‘).val();
        
        //转换为json之后加密
        var str = $.base64.encode(JSON.stringify(obj));


        $.post("你的url地址", 
        { 
            data: str 
        },
           function(data){
             console.log(data);
           });
    }
