WebBrowser和OLECMDID_SELECTALL [英] WebBrowser and OLECMDID_SELECTALL

问题描述

当我使用以下网址打开Goog​​le网页时：

When I open the Google web page using:

WebBrowser1.Navigate('http://www.google.com.au/advanced_search?hl=en');

它会随着光标在编辑框中打开。

因此，当我使用：

it opens with the cursor in the edit box.
So when I use:

WebBrowser1.ExecWB(OLECMDID_SELECTALL,OLECMDEXECOPT_PROMPTUSER,vaIn, vaOut);

它只复制光标所在的位置。不是整个网页，这是我想要复制的。
我的代码是：

it only copies where the cursor is. Not the whole web page, which is what I want to copy. my code is:

procedure Pause()
begin
//code to pause until page loads.
end;

procedure TForm2.Button22Click(Sender: TObject);
var s:String;
    vaIn, vaOut: OleVariant;
begin
    s:='http://www.google.com.au/advanced_search?hl=en';
    WebBrowser1.Navigate(s);
    while WebBrowser1.ReadyState <> READYSTATE_COMPLETE do
      begin
          Pause(1000);
      end;
//------->I need to put code here so the SELECTALL line of code works.<----------
//------->So the cursor isn't in to editbox but as if it has clicked  <---------- 
//------->the webpage                                                 <----------
    WebBrowser1.ExecWB(OLECMDID_SELECTALL,OLECMDEXECOPT_PROMPTUSER,vaIn, vaOut);
end;

如何选择整个网页？

推荐答案

尝试在选择所有内容之前集中身体：

Try focusing the body before selecting all:

((WebBrowser1.Document as IHTMLDocument2).body as IHTMLElement2).focus();
WebBrowser1.ExecWB(OLECMDID_SELECTALL, OLECMDEXECOPT_PROMPTUSER, vaIn, vaOut);

这样说更好的方法是使用 document.body.innerText 来抓取文本，而不是模拟像你这样的选择/复制。

With that said a better approach would be to use document.body.innerText to grab the text, instead of simulating a select/copy like you do.
