javascript:void(0) 调用时，WebBrowser 控件未完成加载 [英] WebBrowser control does not complete loading when javascript:void(0) called

问题描述

我有一个使用 WebBrowser 控件的 C# 应用程序.

在一个页面上，用户可以点击一个按钮来处理一些信息并导航到一个新页面.问题是当用户点击这个按钮时 WebBrowser 似乎停止了.

我处理了代码中的 Navigating、Navigated 和 DocumentCompleted 事件，我看到了 Navigating 事件，但是然后没有别的.

这是被点击的按钮的 HTML:

<div class="clearfix right"><span id="nextbutton"class="button-link button-link btn-reg btn-blue-reg"><span class="hasHover"><a id="btnPay"href="javascript:void(0);"class="buttons">Next:Pay and Print</a></span></span>

点击其他页面上的按钮没有问题.

我假设它与 HTML 的 href="javascript:void(0);" 部分有关，但不知道为什么.在 IE 或 Firefox 等浏览器中，当单击此按钮时，会出现类似于进度条的内容，并说正在处理"几秒钟，然后加载下一页.

编辑:我应该提到导航处理程序触发两次，然后页面冻结.

解决方案

这显然是由 IE7+ 的脚本 URL 缓解" 功能，可以通过禁用 FEATURE_SCRIPTURL_MITIGATION 为您的应用程序修复.

I have an application in C# which uses a WebBrowser control.

On one page the user can click a button to process some information and navigate to a new page. The issue is that when the user clicks this button the WebBrowser just seems to stop.

I handle the Navigating, Navigated and DocumentCompleted events in my code and I see the Navigating event but then nothing else.

This is the HTML for the button being clicked:

<div class="right button-wrapper">
    <div class="clearfix right">
        <span id="nextbutton" 
              class="button-link button-link btn-reg btn-blue-reg">
            <span class="hasHover"><a id="btnPay" 
                href="javascript:void(0);" class="buttons">Next:Pay and Print</a>
            </span>
         </span>
    </div>
</div>

Buttons on other pages can be clicked with no issues.

I am assuming it has something to do with the href="javascript:void(0);" portion of the HTML but do not know why. In a browser such as IE or Firefox when this button is clicked something like a progress bar appears and say "Processing" for a few seconds and then the next page loads.

EDIT:I should mention that the Navigating handler fires twice and then the page freezes.

解决方案

This is apparently caused by IE7+'s "Script URL Mitigation" feature and can be fixed for your application by disabling FEATURE_SCRIPTURL_MITIGATION.
