淘宝的宝贝描述页是ajax异步载入的，所以直接idhttp读一下是弄不到它的源码的。用下面的方法就可以。

代码如下：

unit Unit1;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, ComCtrls, StdCtrls,SHDocVw, ExtCtrls, OleCtrls;

type
  TForm1 = class(TForm)
    Edit1: TEdit;
    Label1: TLabel;
    TabControl1: TTabControl;
    GO: TButton;
    Button1: TButton;
    Button2: TButton;
    Panel1: TPanel;
    RichEdit1: TRichEdit;
    Panel2: TPanel;
    WebBrowser1: TWebBrowser;
    Label2: TLabel;
    procedure GOClick(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure FormShow(Sender: TObject);
    procedure TabControl1Change(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  *******
    { Private declarations }
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}
{$APPTYPE CONSOLE}
uses mshtml;

function GetHtml(const WebBrowser:TWebBrowser): string;
var
  Doc: IHTMLDocument2;
begin
  Doc := WebBrowser.Document as IHTMLDocument2;
  if Assigned(Doc) and Assigned(Doc.body) then
    Result := Doc.body.OuterHtml; //也可以用innerHTML取得其HTML文本
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  //读商品描述页html
  form1.RichEdit1.Text:=GetHtml(form1.WebBrowser1);
  form1.TabControl1.TabIndex:=0;
  form1.Panel1.BringToFront;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  Application.Terminate;
end;

procedure TForm1.FormShow(Sender: TObject);
begin
  //显示控制
  form1.TabControl1.TabIndex:=0;
  form1.Panel1.BringToFront;
  form1.Button1.Enabled:=false;
  WebBrowser1.Silent := True; //禁脚本错误

end;

procedure TForm1.GOClick(Sender: TObject);
begin

  form1.TabControl1.TabIndex:=1;
  form1.Panel2.BringToFront;
  form1.WebBrowser1.Navigate(trim(form1.Edit1.Text));
  form1.Button1.Enabled:=true;
end;

procedure TForm1.TabControl1Change(Sender: TObject);
begin
  case TabControl1.TabIndex of
    0:begin
      form1.Panel1.BringToFront;
    end;
    1:begin
      form1.Panel2.BringToFront;
    end;
  end;
end;

end.
