如何使用ajax发布html代码json数组

Question

如果当 myJson 数组有 1 个对象时我没有任何问题，但 myJson 数组包含的对象多于 1 个对象，我会遇到无法执行后操作的问题。

        var items = [];
        $('.grid-stack-item.ui-draggable').each(function () {
            var $this = $(this);

            items.push({
                ID: $this.attr('data-ItemId'),
                x: $this.attr('data-gs-x'),
                y: $this.attr('data-gs-y'),
                Width: $this.attr('data-gs-width'),
                Height: $this.attr('data-gs-height'),
                UserDashboardId: $this.attr('data-dashboardid'),
                content: $('.grid-stack-item-content', $this).html()
            });
        }); 


        myJson = JSON.stringify(items)
        console.log(myJson);
        $.ajax({
            type: 'POST',
            url: '/Dashboard/SendItem/?json=' + myJson,
            success: function (message) {

            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert("jqXHR:" + jqXHR.status + " errorThrown: " + errorThrown);
            }
        });

试试这个

 var items = [];
        $('.grid-stack-item.ui-draggable').each(function () {
            var $this = $(this);

            items.push({
                ID: $this.attr('data-ItemId'),
                x: $this.attr('data-gs-x'),
                y: $this.attr('data-gs-y'),
                Width: $this.attr('data-gs-width'),
                Height: $this.attr('data-gs-height'),
                UserDashboardId: $this.attr('data-dashboardid'),
                content: $('.grid-stack-item-content', $this).html()
            });
        }); 


        myJson = JSON.stringify(items)
        console.log(myJson);
        $.ajax({
            type: 'POST',
            url: '/Dashboard/SendItem/',
            dataType: "json",
            data: myJson 
            contentType: "application/json",
            success: function (message) {

            },
            error: function (jqXHR, textStatus, errorThrown) {
                alert("jqXHR:" + jqXHR.status + " errorThrown: " + errorThrown);
            }
        });
