解决方案是使用
beforeSendajax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"; }});
