Ajax 调用(传值)一般处理程序(.ashx)

问题:在一般处理程序(.ashx)中累加[index=‘b‘]的值
难点:前台获取JSON值后台解析
解决:
//#region 把index=b的值存在JSON对象中
function AjaxGetSum() {
  var arr = [];
  $("input[index=‘b‘]").each(function () {
    var arrObject = {};
    var tempVal = $(this).val();
    if (!$.gstr.isEmpty(tempVal)) { //本公司自己封装的js $.gstr.isEmpty(st) 判断st是否为空,返回true/false
      arrObject["inValue"] = tempVal;
      arr.push(arrObject);
    }
  });
  var JsonString = JSON.stringify(arr); //转换成JSON类型的字符串
  $.post("HandlerSum.ashx", { jsonVar: JsonString }, function (data) {
    alert(data);
  })
}
//#endregion
