1、如何在dcef3当中执行js代码
procedure TForm1.btnWriteZMClick(Sender: TObject);
var
js: string;
begin
js := 'document.getElementById(''login_button'').click();'; //获得ID为"login_button"并点击
crm.Browser.MainFrame.ExecuteJavaScript(js, 'about:blank', 0); //执行js
end;
2、如何给输入框赋值
procedure TForm1.btnWriteZMClick(Sender: TObject);
var
js: string;
begin
js := 'document.getElementById(''u'').value=''123123'''; //获得ID为"u"的输入框并赋值
crm.Browser.MainFrame.ExecuteJavaScript(js, 'about:blank', 0); //执行js
end;
3、如何获得js执行的返回值
procedure TForm1.btn1Click(Sender: TObject);
var
js: string;
begin
js := 'var uPage=document.getElementById(''errorMessage_lol'').innerText; alert(uPage);'; //获取errorMessage_lol文本值,并通过alert提交给crmJsdialog事件
crm.Browser.MainFrame.ExecuteJavaScript(js, 'about:blank', 0);
end;
//获取内容
procedure TForm1.crmJsdialog(Sender: TObject; const browser: ICefBrowser; const originUrl, acceptLang: ustring; dialogType: TCefJsDialogType; const messageText, defaultPromptText: ustring; callback: ICefJsDialogCallback; out suppressMessage, Result: Boolean);
begin
Memo1.Lines.Clear;
Memo1.Lines.Add(messageText); //这里获得alert弹框发送的内容
Result := False; //这里返回true标识不弹出对话框
end;
