Javascript doPostback在IE 11中失败+；Windows 8.1

我在Windows 8.1预览版的IE 11中看到一个空白页。检查该页后，我认为以下代码可能是罪魁祸首，因为在这些行之后没有进一步的行显示调试器窗口，所以代码在这一行之后中断

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

IE 11

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

您很可能被IIS上的浏览器检测问题绊倒了。在过去的IE10中写过这个，你遇到的问题确实与他的描述相符

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

当时可用的修补程序声明：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

默认情况下，ASP.NET对用户代理字符串使用嗅探技术来检测浏览器。浏览器定义文件涵盖一定范围的浏览器版本。但是，随着版本号的增加，ASP.NET可能无法通过使用用户代理字符串识别浏览器的新版本。在这种情况下，ASP.NET可能会将这些版本作为未知浏览器处理。例如，ASP.NET无法识别具有以下用户代理字符串的Windows Internet Explorer 10：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

但是，由于用户代理的新格式，此修补程序似乎不适用于IE11。有一个名为App_Browsers的NuGet包可能包含修复程序，但在此之前，您必须编写自己的规则

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>


提供有关如何编写浏览器检测文件的详细信息；您将在C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\Browsers中找到现有文件

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

根据，预览中IE11的用户代理为：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

    Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

标准IE正则表达式不承认这一点（因此您看到的问题），但是以下内容应该可以替代：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

    Trident\/7.0; rv:(?'version'(?'major'\d+)(\.(?'minor'\d+)?)(?'letters'\w*))(?'extra'[^)]*)

我没有在实时环境中测试过它，但它确实正确地解析了主版本和次版本，这是解决原始问题的关键-尝试将其作为另一个匹配项添加到文件
ie.browser

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>


请注意-这可能值得关注并为此做出贡献。
我们在C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\Browsers中创建了一个新的“ie11.browser”文件，现在ASP.NET工作正常。创建文件后，我们运行“aspnet_regbrowsers-i”并重新启动IIS。
<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

我们只是复制了IE6-9的功能。我们不知道这是否准确，但ASP.NET现在正在使用运行在Windows 8.1上的Explorer 11
我们的ie11.browser文件如下所示：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>

我也遇到过类似的问题，希望与大家分享我的发现和解决方法。
直截了当地说：
.NET framework 4.0无法正确识别Internet Explorer 11浏览器。可以在一个简单的网站和一个显示请求中浏览器信息的页面上进行验证，方法是调用：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

Request.Browser.Browser

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

Request.Browser.Version

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

没有任何补丁的结果是：
Mozilla 0.0
应用后，浏览器详细信息中提到的修补程序将变为：
IE 11.0
但是，这种方法在没有自定义.browser文件的网站上正常工作。我发现，如果您的站点中的system app_browsers文件夹中只有一个空文件，那么浏览器和版本会再次出错，即Mozilla 0.0（尽管.NET 4.0的修补程序已经安装）。
深入研究这个问题，我设法解决了这个不必要的行为，将Sistemas infoe在上一篇文章中提供的代码包含在.browser文件中，并将其放入网站的app_browsers文件夹中。
我想澄清的是，该问题仅在.NET 4.0中出现，而在.NET 4.5中，浏览器及其版本的检测是正确的

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

我希望这有帮助

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

致以最良好的祝愿，
Mihail
我使用了Sistemas infoe上面提到的ie11.browser文件，将其放在App_browser文件夹中，并在Windows 2003 II6上运行

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

对于预编译的代码，请确保从bin文件夹中删除_browserCapabilitiesCompiler.compiler，以使其能够识别新文件

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

这里给出了不起作用的解决方案
此外，将此文件放在C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\Browsers中，并使用aspnet\u regbrowsers.exe注册它-我无法工作

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

差点忘了提。如果这个解决方案不起作用，下一步我会尝试这个。
Microsoft修补程序“2600088”肯定不起作用，因此您必须采用.browser文件路径

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

使用最新版本的IE11，您需要对上面发布的ie.browser文件RegEx进行一个小的修改。确保在分号和空格之间的UA字符串中允许更多字符。如果你的正则表达式技能很糟糕（很像我的），那就是一个周期，然后是一个明星

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

旧的：

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

如果返回11，则JS错误应该消失。瞧

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

更新：
2013年10月发布了第二个MS修补程序。我现在可以删除.browser文件，只需使用补丁。到目前为止运作良好请参见
我发现最简单的修复方法是安装.Net 4.5.1，我甚至不需要更改应用程序使用的版本
 不同的ISP会将其服务器锁定到特定版本，而忽略有价值的修复。
<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

英国的FASTHOSTS已经锁定了他们的.NET3.5服务器，并且没有应用IE修复程序，让程序员根据需要引入浏览器文件

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

通常的策略是用ISP的呼喊“这确保了程序员有一个稳定的环境”来锁定服务器

<script type="text/javascript">
//<![CDATA[
var theForm = document.forms['aspnetForm'];
if (!theForm) {
theForm = document.aspnetForm;
}
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
    theForm.__EVENTTARGET.value = eventTarget;
    theForm.__EVENTARGUMENT.value = eventArgument;
    theForm.submit();
}
}
//]]>
</script>

以下是从Scott Hanselman网站/详细解决方案中闪现出来的，当时IE10即将爆炸并在最近进行了调整。例如，没有它
