delphi 中调用javascript的问题

Question

我想在delphi里调用下面的脚本
window.showModalDialog("http://kkk.com.cn/exchange/rtCheckNYSuc.asp?userName=zhj&userPwd=123456&JGMC=宁波市研究院&instrID=ZC87872586&checkNo=ZH034-80825065&upTime=2008-11-26 16:12:38", "", "dialogWidth:0px; dialogHeight:0px; dialogLeft:0px; dialogTop:0px; status:no; directories:yes;scrollbars:no;Resizable=no;");
并获取返回值。

給一個測試的DEMO，拋磚引玉unit Unit1;
interfaceuses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, OleCtrls, SHDocVw;type
  TForm1 = class(TForm)
    WebBrowser1: TWebBrowser;
    Button1: TButton;
    Button2: TButton;
    Button3: TButton;
    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure Button3Click(Sender: TObject);
  end;var
  Form1: TForm1;implementation{$R *.dfm}procedure TForm1.FormCreate(Sender: TObject);
var
  HtmlPath: string;
begin
  WebBrowser1.Left := -WebBrowser1.Width; {隐藏 WebBrowser1}
  HtmlPath := ExtractFilePath(ParamStr(0)) + 'Test.htm';
  WebBrowser1.Navigate(HtmlPath);
end;procedure TForm1.Button1Click(Sender: TObject);
var
  str: Variant;
begin
  str := WebBrowser1.OleObject.document.parentWindow.JsStr2('12345');
  ShowMessage(str);
end;procedure TForm1.Button2Click(Sender: TObject);
var
  num: Variant;
begin
  num := WebBrowser1.OleObject.document.parentWindow.JsNum2(4);
  ShowMessage(num);
end;procedure TForm1.Button3Click(Sender: TObject);
begin
  WebBrowser1.OleObject.document.parentWindow.JsMsg('ABC');  {也可以这样:}
  WebBrowser1.OleObject.document.parentWindow.execScript('JsMsg("ABCDEFG")', 'JavaScript');
end;end.

Answer 2

应该就是一个URL传参吧
可以直接用idhttp进行传参，用ResponseText返回结果
