ajax给全局变量设置值，请先关掉异步上传效果

Posted 2021-03-23 koaler

$.ajax({
          type: ‘POST‘,
          url: "/downloadExcelInfo",
          timeout: 0,
          async: false,
          contentType: "application/x-www-form-urlencoded;charset=utf-8",
          data: {
              storename:storename,
              idstr:idstr,
              goodsnames:goodsnames,
              pictures:pictures,
              column1:column1,
              filename:filename
          },
          success:function(result){
              ssss = result;
              $("input[name=‘hahaha‘]").attr("value",result);
              alert(ssss);
          },
          error:function(error) {

          }
      });

    ssss = result; //给全局变量赋值的时候，要先设置 async: false, 否知赋值是暂时的，不会有效果的。
