我想将页面上的一些数据发送到servlet

所以我写了下面的jquery来做这件事

我使用所有数据来构建一个json字符串,并直接将其发送到servlet

但我不知道如何从servlet中的ajax获取整个数据

$("#save").click
(
    function()
    {
        $.ajax
        (
            {
                url:'/WebApplication1/Controller',
                data:'{"name":"abc","address":"cde"}',
                type:'post',
                cache:false,
                success:function(data){alert(data);},
                error:function(){alert('error');}
            }
        );
    }
);

如果从chrome看到请求标头的Form Data段

你会看到整个json字符串是关键.

我在提交此表格时遇到困难：

<form action="/someurl" method="post">
    <input type="hidden" name="token" value="7mLw36HxPTlt4gapxLUKWOpe1GsqA0I5"> 
    <input type="checkbox" class="mychoice" name="name" value="apple"> Apple
    <input type="checkbox" class="mychoice" name="name" value="orange"> Orange      
    <input type="checkbox" class="mychoice" name="name" value="pear"> Pear
  </form>

还有 jquery 位：

$('.mychoice').click( function() {
    $.ajax({
        url: '/someurl',
        type: 'post',
        dataType: 'json',
        success: function(data) {
                 //  ... do something with the data...
                 }
    });
});

但是当我单击复选框时什么也没有发生。我怎样才能解决这个问题？

更新：值得一提的是，该表单位于引导模式中。
