jQuery：无法将Json对象添加到Ajax请求

Question

Overview:我正在制作一个Web工具，使用图表（Highcharts）在数字平台上显示不同制片厂出售的电影总数。 这些图表是动态的，因此用户可以使用过滤器列表来更改结果。

Filter 1 - Studios:使用此过滤器，用户可以选择希望查看其销售量的不同工作室。

Filter 2 - Period:这是他想要查看销售情况的持续时间。 正是这个过滤器给我带来了问题。

基本上，周期的选择不会随AJAX请求一起发送，因此对图表没有影响。 周期的默认值（使用momentjs库设置）也与AJAX请求一起使用。 它是期间中的更改，不会被添加到请求中。

本身没有错误消息。

编码：

$(document).ready(function(){

var btnStudiosDiv = $('#btnStudios');

var getStudios = function () 
// Get all studio's from buttons with .active class               
var studios = $('button.active', btnStudiosDiv).map(function () {
    return $(this).val();
}).get();

// If no studio's found, get studio's from any button.
if (!studios || studios.length <= 0) {
    studios = $('button', btnStudiosDiv).map(function () {
        return $(this).val();
    }).get();
}

return studios;
};



var periodFrom = (moment().format('WW')-11)
var periodTo = moment().format('WW')
var output = {};

var show = function (studios) {
output['Studios'] = studios,

var per = {Period: {"From":["W" + periodFrom],"To":["W" + periodTo]}};
$.extend(output, per);
$('.list').html(JSON.stringify(output)); //Display Json Object on the Webpage

$.ajax({  //Ajax call to send the Json string to the server

        type: "POST", 
        data: {"jsontring": JSON.stringify(output)},
        url: "http://localhost:8080/salesvolume" ,
        contentType: "application/json",
        dataType: "json",
        cache: false,
        beforeSend: function() {
        $('#container').html("<img class = 'ajload' src='loading.gif' />");
         },

        success: function(data){
                                alert(  )   ;
                                $('#container').highcharts(data);
                                },
        error: function() {
                            alert("Something is not OK :(") 
                                },

        }); 





};

var timer; //To create a time delay of 2 Secs for every selection
$(".btn").click(function () {


$(this).toggleClass('active');
// Fetch studios
var studios = getStudios();


// Remove previous timeOut if it hasn't executed yet.

if(timer)
    clearTimeout(timer);

// Wait 2 sec
timer = setTimeout(function () {
    // Fill list with the studios
    show(studios);
},2000);


});

// Show the json on page load
show(getStudios());

$('.ui-weekpickerTo .ui-datepicker-calendar tr').on('mouseleave', function() { $(this).find('td a').removeClass('ui-state-hover'); });


});





});     

如果有人可以指出我要去哪里，那将真的很有帮助。

Note:该工具上还添加了多个其他过滤器，但是为简单起见1刚刚提到了两个重要的过滤器。

Answer 1

我认为数据应该是这样的

$.ajax({
        type: "POST", 
        **data: "{\"jsontring\":" + JSON.stringify(output) + "}",**
        url: "http://localhost:8080/salesvolume" ,
        contentType: "application/json",
        dataType: "json",
        cache: false,
        beforeSend: function() {
        $('#container').html("<img class = 'ajload' src='loading.gif' />");
         },

        success: function(data){
                                alert(  )   ;
                                $('#container').highcharts(data);
                                },
        error: function() {
                            alert("Something is not OK :(") 
                                },

        });
