发送确认请求前显示确认消息

发送确认请求前显示确认消息

解决方案是使用

beforeSend

ajax属性。

beforeSend是发送之前的请求前回调函数.beforeSend函数中返回false将取消请求。

beforeSend:function(){     return confirm("Are you sure?");},

AJAX

$.ajax({      url: "UBRDashboard.aspx/GetDllValue",      dataType: "json",      type: "POST",      contentType: 'application/json; charset=utf-8',      data: JSON.stringify({ ddlOduModel: ddlOduModel, ddlAntModel: ddlAntModel, ddlOMTModel: ddlOMTModel, ddlSapID: ddlSapID, ddlVendorName: ddlVendorName, strReqID: r.d, ddlSapDescVal: ddlSapDescVal, SITE_ADD: SITE_ADD, LATITUDE: LATITUDE, LONGITUDE: LONGITUDE, ddlEQP_SEQ: ddlEQP_SEQ, txtlinkID: txtlinkID, RJ_QUANTITY: RJ_QUANTITY, USER_NAME: USER_NAME, CREATED_DATE: CREATED_DATE, LOCATIONTYPE: LOCATIONTYPE, TOWERTYPE: TOWERTYPE }),      async: true,      processdata: false,      cache: false,      beforeSend:function(){         return confirm("Are you sure?");      },      success: function (r) {        if (r.d == "OK") {        alert('Record Saved successfully');        window.location.href = "UBRDashboard.aspx";      },      error: function (xhr) {  alert('Error while selecting list..!!');  window.location.href = "ErrorPage.aspx";      }});
