如果提取网页中的变量 - 回复 lancernig 的问题

问题来源: http://www.cnblogs.com/del/archive/2008/04/02/1131232.html#1133889

答案: WebBrowser1.OleObject.Document.ParentWindow.变量名;

譬如有这样一个页面(lancernig 举的例子), 如何提取其中的 pvs 呢:

---

测试页 ...

假定是把页面保存在 'c:\temp\test.htm', 测试代码如下:

---

unit Unit1;

interface

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

type
  TForm1 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.FormCreate(Sender: TObject);
begin
  WebBrowser1.Navigate('c:\temp\test.htm');
end;

procedure TForm1.Button1Click(Sender: TObject);
var
  s: string;
begin
  {提取 smoneys}
  s := WebBrowser1.OleObject.Document.ParentWindow.smoneys;
  ShowMessage(s);

  {提取 pvs}
  s := WebBrowser1.OleObject.Document.ParentWindow.pvs;
  ShowMessage(s);
end;

end.
