Asp.NET窗体卸载之前·····

Question

window.onbeforeunload = function() {
// UpdateLookTimes(1);
var userId = "<%=Community.web.NewPlay.Helper.PlayHelper.UserId %>";
var currentStudyTime = document.getElementById("txt_IntMin").value;
var videoLen = jwplayer("container").getDuration();
var videoStep = 1;
var curriculumId = '<%=CourseID %>';
var d = new Date();
if (videoLen - currentStudyTime < 200) {
alert("恭喜您完成本门课学习!");
}
var url = "/NewPlay/RecordStudyPropress.ashx?Date=" + d + "&userId=" + userId + "&currentStudyTime=" + currentStudyTime + "&allTime=" + videoLen + "&setup=" + videoStep + "&curriculumId=" + curriculumId + "&" + status;
$.get(url, function (data) { });

    };


            我在RecordStudyPropress.ashx里下了断点但是关闭窗体是并没有跳转进来···只有在手动在浏览器中调试时才会跳进本地的RecordStudyPropress.ashx中来，有什么方法保证在窗体卸载前一定执行RecordStudyPropress.ashx中的处理程序

Answer 1

onbeforeunload不要调用alert，confirm那种弹窗代码，除了ie支持，其他浏览器不支持

你要执行ashx，ajax必须改为同步的，$.get默认是异步的，改为$.ajax来调用

 $.ajax({url:url,async:false})
