导航网页的槽的目的,使用嵌入式Web浏览器 [英] Navigating trough objects of a web page, using an embedded web browser
问题描述
我有一个Windows窗体应用程序使用 web浏览器
控件来显示嵌入网页。该文件是(成功),使用加载:
I have a Windows Forms application that uses a WebBrowser
control to display an embedded web page. The file is (successfully) loaded using:
webHelp.DocumentStream=
Assembly.GetExecutingAssembly()
.GetManifestResourceStream("MyAssembly.help.html");
为了这个工作(即文件/显示加载)我设置了 webHelp.AllowNavigation = FALSE;
。我不完全理解为什么,但如果它设置为true,则不会显示该页面。
In order for this to work (i.e. the file to be loaded/displayed) I set the webHelp.AllowNavigation = false;
. I don't fully understand why, but if it's set to true, the page is not displayed.
在我的HTML文件(参见下文),我希望能够浏览低谷的不同部分。但是,当我点击一个链接时,浏览器控件不进入目标元素。该网页作品在独立的Internet Explorer 10细,所以它必须有一些做的控制,更具体地说是 AllowNavigation
属性。 MSDN没有多大帮助。
In my HTML document (see bellow) I want to be able to navigate trough different sections. But when I click on a link, the browser control does not go to the targeted element. The web page works fine in the stand-alone Internet Explorer 10, so it must have something to do with the control, more specifically the AllowNavigation
property. MSDN didn't help much.
我怎样才能做到这一点的导航行为?有没有加载HTML文件,而不 AllowNavigation
属性设置为false的另一种方式?
How can I achieve this navigation behavior? Is there another way of loading the HTML file without setting the AllowNavigation
property to false?
这是我简单的HTML文件:
This is my simple HTML file:
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>Using this tool</title>
</head>
<body>

<p id="selectOption">Selecting a conversion action</p>
<p>*action selection*</p>
<a href="#contents" class="goToTop">Go To Top!</a>
</div>
</body>
</html>
编辑:经过额外的测试,我发现了问题的根源。设置为网址
属性的值,运行应用程序,事后清算这个值后,问题出现了。嵌入式页面没有加载任何更多的,除非 AllowNavigation
属性设置为假
。有两个解决方案,在我的答案描述如下
After additional tests I found the root of the problem. The problem appeared after setting a value for the URL
property, running the application and afterwards clearing this value. The embedded page is not loaded any more, unless the AllowNavigation
property is set to false
. There are two solutions, described in my answer bellow.
推荐答案
编辑:找出原因后问题(见编辑的问题)我现在可以提出三种解决方案:
After finding the cause of the problem (see the edit to the question) I can now propose three solutions:
1。 web浏览器
控制替换:结果
只需删除现有的 web浏览器
控件并添加新的一个。该解决方案不要求 AllowNavigation
财产的任何修改。不要修改网址
属性。
1. WebBrowser
control replacement:
Simply delete the existing WebBrowser
control and add a new one. This solution does not require any modification of the AllowNavigation
property. DO NOT modify the URL
property.
2。当删除和添加一个新的 web浏览器
控制不是一个选项:结果
由于 AllowNavigation
财产影响负荷和网页显示,没有理由为它留给假
之后。设置早在所示
事件属性解决导航问题,而不需要其他的改变(例如,在HTML文件或注册表):
2. When deleting and adding a new WebBrowser
control is not an option:
Since the AllowNavigation
property was influencing the loading and displaying of the web page, there was no reason for it to be left to false
afterwards. Setting back the property in the Shown
event solved the navigation problem, without requiring other alterations (e.g. in the HTML file or the Registry):
private void helpForm_Shown(object sender, EventArgs e)
{
webHelp.AllowNavigation = true;
}
3。正在重置的文件
结果
它接缝的文件
属性获取(自动)如果初始化网址
属性是设置和重置一次。添加 webHelp.Document.OpenNew(真);
然后再加载资源流解决,而不需要对这个问题重新添加 web浏览器
键,无需修改 AllowNavigation
属性。
3. Reseting the Document
It seams that the Document
property gets (automatically) initialized if URL
property is at one time set and reset. Adding webHelp.Document.OpenNew(true);
before loading the resource stream solves the problem without the need for re-adding the WebBrowser
and without modifying the AllowNavigation
property.
