javascript - 如何在 jQuery 中解析表单数据以使用 JSON？

Question

 var checkedValues = $('.required:checked').map(function () {
                return this.value;
            }).get();

            var arr = new Array(10);
            alert(checkedValues);
            alert("number of values in it " +checkedValues.length);
            if (checkedValues.length > 1) {

                alert("I am inside if ");
                 arr = checkedValues.split(',');

                alert("I am done with the split ");
            }
            else {
                arr = checkedValues;
                alert("No split needed ");
            }





               $.getJSON('@Url.Action("testcata", "home")' +  + '?Type=' + "@(Session["typ"])" + "&city=" + "@(Session["cit"])" + "&chkd=" + checkedValues,


            function (data) {

                           //code
                        })

In controller :
 public ActionResult testcata(string Type, int? city, int[] chkd)
    {
      //code
    }

我试图获取已选中的复选框的值并将它们存储在数组中，然后通过 json 函数发送到 Controller 。未显示警报(“我已完成拆分”)。请帮助我。

看看.serializeArray() :

var checkedValues = $('.required:checked').serializeArray();

它返回一个准备好 JSON 的数组，如下所示:

[
  {
    name: "a",
    value: "1"
  },
  {
    name: "b",
    value: "2"
  },
  {
    name: "c",
    value: "3"
  },
  {
    name: "d",
    value: "4"
  },
  {
    name: "e",
    value: "5"
  }
]
