I have used the above code to display a page named Default.aspx in a modal popup but unfortunately it gives me following error

enter image description here

Am I doing something wrong Or its not possible to display a page in modal popup in SharePoint Online?

The same code works perfectly on SharePoint 2013 on premise.

Can anyone help?

Thanks.

Use below script in CEWP

<a onclick="modalcall()" href="#">New Request</a>
<script type="text/javascript">function modalcall() { 
    SP.UI.ModalDialog.showModalDialog({ 
    url: "NewForm.aspx", 
    title: "New Form", 
    allowMaximize: true, 
    showClose: true, 
    dialogReturnValueCallback: refreshCallback
    }); 
}; 
function refreshCallback(dialogResult, returnValue) { 
SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK);}</script>

the content cannot be displayed in a frame sharepoint

You have two options, use a html page if it's possible, or add <WebPartPages:AllowFraming ID="AllowFraming" runat="server" /> to your aspx page.
