德尔福铬 - 当网页按钮是通过用户点击启动在Delphi应用程序的命令(Delphi Chromiu

我用了Delphi应用程序铬成分。

我想以下行为：

当用户点击网页中的特定按钮，Delphi的应用程序（“容器”）必须执行命令（启动外部可执行文件...）。

可能吗 ？

既然你居然问了DOM事件侦听click事件，请检查下面的例子听谷歌搜索按钮单击事件（ID为元素gbqfba ）：

uses
  ShellAPI, cefvcl, ceflib;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Chromium1.Load('www.google.com');
end;

procedure OnClickEvent(const AEvent: ICefDomEvent);
begin
  ShellExecute(Form1.Handle, nil, 'notepad.exe', nil, nil, SW_SHOWNORMAL);
end;

procedure OnExploreDOM(const ADocument: ICefDomDocument);
var
  DOMNode: ICefDomNode;
begin
  DOMNode := ADocument.GetElementById('gbqfba');
  if Assigned(DOMNode) then
    DOMNode.AddEventListenerProc('click', True, OnClickEvent);
end;

procedure TForm1.Chromium1LoadEnd(Sender: TObject; const browser: ICefBrowser;
  const frame: ICefFrame; httpStatusCode: Integer; out Result: Boolean);
begin
  if Assigned(frame) then
  begin
    // here you should check the frame.Url to verify if you're on the right URL
    // before you try to search for the element and attach the event if found
    frame.VisitDomProc(OnExploreDOM);
  end;
end;
