如何告诉IE忽略以前收到的格式错误的HTML并呈现不同的HTML？ [英] How to tell IE to ignore previously received malformed HTML and render different HTML?

问题描述

我们有一个运行.Net 4.0的MVC.Net 2应用程序。在某些情况下，我们的视图中的嵌入代码可能会出错，向浏览器发送格式错误的HTML。

We have an MVC.Net 2 application running with .Net 4.0. There are cases where embedded code in our views may err, sending malformed HTML to the browser.

如何告诉Internet Explorer关闭所有打开的属性和元素，以便它可以正确呈现错误消息？

How can I tell Internet Explorer to close any open attributes and elements so it can properly render an error message?

要捕获并记录嵌入代码中的错误，我将视图的HTML和嵌入代码包含在try-catch的try块中结构，只需要在记录错误后向用户显示一条简单的消息。

To catch and log errors in the embedded code, I'm enclosing the view's HTML and embedded code in the try block of a try-catch structure and just want a simple message displayed to the user after logging the error.

示例：

<%
try {
%>
<div id="div1">
    <label class="<%=embedded.code.that.may.err%>">mylabel</label>
    <div id="div2" class="data-style">
        <%=more.embedded.code.that.may.err%>
    </div>
</div>
<%
}
catch(Exception ex) {
    (new LogManager()).Save(ex);
%>
<div style="color:red;font-weight:bold;font-size:large;">
    Sorry, there was an error.
</div>
<%
}
%>

推荐答案

不要。让您的容易出错的代码运行并将结果放入字符串变量中。把它放在try-catch块中。然后，没有错误你可以写出整个#div1块，包括你已经评估的字符串，知道不会有错误。

Don't. Have your error prone code run and put the result into string variables. Put that in the try-catch block. Then, it there's no error you can write out the entire #div1 block including your already evaluated strings knowing that there won't be an error.
