Where is onBeforeClose?

Dear forum,

Sorry for my first thread if it is a piece of cake but I couldnt find any article about it.

Normally in the previous version (v4.10.10), there used to be “onBeforeClose” event for popups;

But in the newest release (v5.21.2), we don’t have it.

There is a note announces that it’s been removed but without mentioning neither the reason nor the alternatives.

Could you please help, how can we interupt the event of a popup onClose?

Thanks in advance,


You can solve that using a custom button. In v5 you can even assign a keyboard keyCode to activate the button:

var popup = mobiscroll.popup('#mypopup', {
  buttons: [
      text: 'Save',
      keyCode: 'enter',
      handler: function () {
        if (...) {  // check validity

Let me know if this helps!

Hi Hunor, I appreciate your response.

I only want to catch when the user clicks somewhere outside of the popup in order to avoid auto-popup close unintentionally. I want to show a confirm message if they really want to close the popup or not.

Any idea?
Thanks in advance.
