delphi 中webbrowser 屏蔽脚本错误提示
delphi 用 webbrowser 登录 百度新闻等网站是会报错 脚本错误，但是对浏览网站没有什么影响，
我尝试用 webbrowser.silent:=true； 屏蔽提示框，但是这样有一个弊端，就是很有可能将其他的可用提示框屏蔽掉，例如 路由器网关的登陆界面。
网上搜了一下有人说只屏蔽 脚本报错会很烦但是没有说明办法，又没偶大神会通过代码只屏蔽脚本错误而不屏蔽其他提示框？？ webbrowser delphi 脚本 提示框
[解决办法]
以下代码可以屏蔽js提示.
备注: JS提示的屏蔽会带来其他问题, 比如屏蔽询问JS通行的窗口会导致界面使用问题

unit Unit11;

  Dialogs, StdCtrls, OleCtrls, SHDocVw{, ActiveX, ShellAPI};

  TForm11 = class(TForm)
    wb1: TWebBrowser;
    edtURL: TEdit;
    procedure edtURLKeyDown(Sender: TObject; var Key: Word; Shift: TShiftState);
    procedure wb1NewWindow2(ASender: TObject; var ppDisp: IDispatch;
      var Cancel: WordBool);
    procedure wb1NavigateComplete2(ASender: TObject; const pDisp: IDispatch;
      var URL: OleVariant);
