获取页面的checkbox，并给参数赋值

需求：

需要发送的请求：

选中，发送name值，参数为true，不选中，发送name值，参数为false

方法如下：

$('#courseware_permissions_save_button').click(function(){
       //
       var boxes = $('.courseware_permission_checkbox');
       var myData = {};
        for(var i=0,j=boxes.length;i<j;i++) {
            var box = boxes[i];
            if(box.checked)
                myData[box.value] = 'true';
            else
                myData[box.value] = 'false';
        }

        jQuery.ajax( {
            url : "/direct/site/${param.siteId}/setPerms",
            type : 'POST',
            data : myData,
            async : false,
            dataType: 'text',
            success : function(data) {
                if(data) window.location.href='${pageContext.request.contextPath}/cw/index.do';
            },
            error : function(xmlHttpRequest,status,error) {
               alert("ERROR");
            }
        });
       //return false;
   });
