Microsoft Edge Issue: Object doesn't support property or method 'showModalDialog' error

Hi,

Can somebody help me in resolving this issue. I am getting the below error upon clicking on a button in a page when checked in Microsoft Edge browser.

Error:Object doesn't support property or method 'showModalDialog'.

I have even tried placing the below meta tag but it did not worked.

<meta http-equiv="X-UA-Compatible" content="IE=edge">

'showModalDialog' is working when checking in IE9 and IE 11 modes.

Kindly help me in this.

Thank you.
