单击 iFrame 内的元素
我的内置浏览器下载了一个页面。
在此页面的“body”下，有一个“iframe”标签。
在此 iframe 内部，还有另一个代码（div 标签、表格等）。
但我不知道如何访问它们。
webBrowser1.Document.GetElementById("myiFrame").innerHTML // gives out empty result as if there is nothing there.
webBrowser1.Document.GetElementById("myiFrame").FirstChild.innerHTML // gives an error as if there is no first child.
webBrowser1.Document.GetElementById("mylink") // error as if it doesn't exist
webBrowser1.Document.GetElementsByTagName("a")[2] // error as if it doesn't eist
我已经没有选择了。
我需要单击该框架深处的一个东西：
body -> div -> div -> div -> form -> div -> div -> div -> div -> div -> div -> div -> div -> table -> tbody -> tr -> td -> a
My built-in browser downloaded a page.
On this page under "body", there is an "iframe" tag.
Inside of this iframe, there is another code (div tags, table etc).
But I don't know how to access them.
webBrowser1.Document.GetElementById("myiFrame").innerHTML // gives out empty result as if there is nothing there.
webBrowser1.Document.GetElementById("myiFrame").FirstChild.innerHTML // gives an error as if there is no first child.
webBrowser1.Document.GetElementById("mylink") // error as if it doesn't exist
webBrowser1.Document.GetElementsByTagName("a")[2] // error as if it doesn't eist
I ran out of options.
I need to click a thing that is deep inside of this frame:
body -> div -> div -> div -> form -> div -> div -> div -> div -> div -> div -> div -> div -> table -> tbody -> tr -> td -> a

做
Document.InvokeScript([无论您要单击什么]工作吗？
您确定已全部下载吗？Webbrowser.ReadyState 会为每一帧触发 Ready。
Does
Document.InvokeScript([whatever it is you want to click]Work?
Are you sure that its all downloaded? Webbrowser.ReadyState triggers Ready for every frame.
您应该加载 iframe 中出现的页面，而不是加载父页面并浏览它。您可以获取 iframe 的 src 属性并导航到该页面。这样你就可以轻松访问你需要访问的节点。
Instead of loading the parent page and going through it, you should load the page which appears within iframe. You can get src attribute of iframe and navigate to the page. This way you can easily access nodes you need to access.
