J.O*_*son 4 javascript asp.net ajax jquery
我已经有这个问题已经有一段时间了,并尝试了各种解决方案,使用各种标签编辑Webconfig.
我在我的网页上使用Updatepanels,计时器和AJAX.(可能是AJAX会引发错误吗？)
我真的不知道如何定义问题,因为我真的不知道在哪里追踪它.
我已经在主页面上放置了一个onload(不知道那是不是正确的)下面是一些标记代码和我认为我的Javascript代码会抛出错误.

JAVASCRIPT代码:
if (window.addEventListener) window.addEventListener("load", load(), true);
else window.onload = load();
function load() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}
function EndRequestHandler(sender, args) {
// NOT IMPORTANT
}
我刚刚解决了这个问题.我认为.我知道该函数是在构建DOM之前运行的.
所以我就这样做了
$(document).ready(function () {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
});
一个问题尚未成为主流.当我点击Imagebutton btnAdd时控制台说:
Uncaught ReferenceError: btnAddQuestion_Click is not defined
onclick
这会将我引导到我写入此ImageButton的代码行.
Internet Explorer根本不喜欢这个.但是其他浏览器就像没有任何东西一样继续进行,即使错误消息出现在Dev-Console中也是如此.
Button功能适用于.唯一的问题是错误.
编辑:现在解决了.我正在使用"OnClientClick".在ImageButtons上.我将其更改为OnClick,这解决了这个问题.我不知道两个人之间的区别,但只要它有效,我很高兴.
