当我使用以下方法打开Google网页时:
WebBrowser1.Navigate('http://www.google.com.au/advanced_search?hl=en');
随即在编辑框中显示光标。
所以当我使用:
WebBrowser1.ExecWB(OLECMDID_SELECTALL,OLECMDEXECOPT_PROMPTUSER,vaIn, vaOut);
它仅复制光标所在的位置。不是整个网页,这是我要复制的内容。
我的代码是:
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?
最佳答案
在全部选择之前,尝试将身体聚焦:
((WebBrowser1.Document as IHTMLDocument2).body as IHTMLElement2).focus();
WebBrowser1.ExecWB(OLECMDID_SELECTALL, OLECMDEXECOPT_PROMPTUSER, vaIn, vaOut);
话虽如此,一种更好的方法是使用
document.body.innerText
捕获文本,而不是像您那样模拟选择/复制。
