javascript alert title

How to change javascript alert title from 'Javascript Alert - 127.0.0.1:54007' to any custom title? please answer me fast

Hi Sonali,

You could overwrite the default implementation of the javascript alert function, see:

http://stackoverflow.com/questions/1729501/javascript-overriding-alert

You could create a custom UI alert dialog using jQuery, see for example:

http://andrewensley.com/2012/07/override-alert-with-jquery-ui-dialog/

The other solution would be to fix it in the Chromium engine. We would need to implement CefJSDialogHandler::OnJSDialog callback:

///
  // Called to run a JavaScript dialog. The |default_prompt_text| value will be
  // specified for prompt dialogs only. Set |suppress_message| to true and
  // return false to suppress the message (suppressing messages is preferable
  // to immediately executing the callback as this is used to detect presumably
  // malicious behavior like spamming alert messages in onbeforeunload). Set
  // |suppress_message| to false and return false to use the default
  // implementation (the default implementation will show one modal dialog at a
  // time and suppress any additional dialog requests until the displayed dialog
  // is dismissed). Return true if the application will use a custom dialog or
  // if the callback has been executed immediately. Custom dialogs may be either
  // modal or modeless. If a custom dialog is used the application must execute
  // |callback| once the custom dialog is dismissed.
  ///
  /*--cef(optional_param=accept_lang,optional_param=message_text,
          optional_param=default_prompt_text)--*/
  virtual bool OnJSDialog(CefRefPtr<CefBrowser> browser,
                          const CefString& origin_url,
                          const CefString& accept_lang,
                          JSDialogType dialog_type,
                          const CefString& message_text,
                          const CefString& default_prompt_text,
                          CefRefPtr<CefJSDialogCallback> callback,
                          bool& suppress_message) {
    return false;
  }

Please create an issue in the tracker if you need that.

It would be nice if this were fixed in the Chromium engine.

Thank you Czarek for the links to the other two solutions,.

Please create an issue then.

I discourage usage of javascript alerts or other javascript dialogs as there are display issues on Windows XP. See this issue in the Chromium Embedded Framework that needs to be fixed:

"CEF3: JavaScript dialogs are shown incorrectly in Windows XP"

https://code.google.com/p/chromiumembedded/issues/detail?id=760

I see now that this issue is tagged as "NextRelease", so it is going to be fixed in the next CEF release.

Hi Czarek,

The confirm() and prompt() cannot be easily replaced, because of the synchronous way they work:

if(confirm('Do Something?')){
   // do stuff
}

These functions block UI thread until user clicks OK/Cancel in the dialog. Such behavior cannot be replaced with javascript.

For now you could disable these functions for example:

window.confirm = function(s) { return false; }
window.prompt = function(s) { return ""; }

Star Issue 73 and you will be notified when titles for javascript dialogs get fixed.
