看页面源码 BOLD 部分，是网页上的一个 BUTTON(arid=700040002 artype="Control" ardbn="Btn_Edit" )。当这个页面满载时，我想在 delphi 中按下按钮。

这应该这样做：

procedure ClickElementByContent(Document : IDispatch; TagFilter : WideString; Content: WideString);

var Doc   : IHTMLDocument3;
    El    : IHTMLElement;
    Elements : IHTMLElementCollection;
    Index    : Integer;

begin
 Doc := Document as IHTMLDocument3;
 if Assigned(Doc) then
  begin
   Elements := Doc.getElementsByTagName(TagFilter);
   for Index := 0 to Pred(Elements.length) do
    begin
     El := Elements.item(EmptyParam, Index) as IHTMLElement;
     if ContainsText(El.innerText, Content) then
      begin
       El.Click;
       Break;
      end;
    end;
  end;
end;

如何使用：

procedure clickthebutton;
begin
 ClickElementByContent(Webbrowser1.Document, 'DIV', 'DEAL');
end;

procedure TTrackITOrderForm.Btn_DealClick(Sender: TObject);
var
Document : IHTMLDocument2 ;
ButtonDiv , temp : IHTMLElement ;
ElementCount , I : Integer ;
begin
Document := wb1.Document as IHTMLDocument2 ;
ElementCount := Document.all.length ;
for i := i to ElementCount-1 do
begin
temp := Document.all.item(i,'') as IHTMLElement ;
lst1.Items.Add(temp.id+'-->'+temp.innerText)  ;
if (temp.tagName = 'DIV') and (temp.innerText = '处理') then
begin
ShowMessage(temp.innerText);
ButtonDiv := temp ;
Break ;
end;
end;
if ButtonDiv <> nil then
ButtonDiv.click ;
end;
