使用HTMLDocument的操纵​​HTML并显示在web浏览器控制 [英] Using HTMLDocument to manipulate HTML and show it in WebBrowser-control

问题描述

我试图操纵在WPF web浏览器控制一个请求的文档。我已经设法它来调用加载文件的JavaScript，但我不能够改变显示HTML的code。在控件本身。

I am trying to manipulate a requested document in the WPF WebBrowser-control. I already managed it to invoke JavaScript on loaded document, but I am not able to change the shown HTML-code in the control itself.

我的（非常简化）$ C $在OnNavigating处理程序C相类似这样的：

My (very simplified) code in the OnNavigating-Handler looks like this:

mshtml.HTMLDocument doc = (mshtml.HTMLDocument)View.browser.Document;
HTMLTableClass table = doc.getElementById("someTable") as HTMLTableClass;

if (table != null)
{    
    table.appendChild((IHTMLDOMNode)(doc.createElement("<tr>") as IHTMLElement));
}
doc.close();

该-element不会被追加到在控件中显示的文档。
任何提示都非常AP preciated！

The -element doesn't get appended to displayed document in the control. Any hints are very appreciated!

推荐答案

我终于得到它。其唯一可能通过增加行和细胞，我想避免在首位改变表的内容。我的方法是直接更改-tag，其中没有工作的内容​​。

I finally got it. Its only possible to change the content of the table by adding rows and cells which i wanted to avoid in first place. My approach was to directly change the content of the -tag, which didnt work.

mshtml.IHTMLTableRow row = table.IHTMLTable_insertRow(-1) as mshtml.IHTMLTableRow;
mshtml.IHTMLElement c = (mshtml.IHTMLElement)row.insertCell(0);
c.innerText = "some";
mshtml.IHTMLElement c1 = (mshtml.IHTMLElement)row.insertCell(1);
c1.innerText = "text";
