SharePoint Modal Dialog does not work under SharePoint 2013

When migrating our Solutions2Share License Management Solution from SharePoint 2010 to SharePoint 2013 the SharePoint Modal Dialog did not open.

SharePoint 2010 Example:

   1: function ShowServerInformation() {
   2:         var options = {
   3:             url: '/_admin/Solutions2Share/LicenseManagement/GeneralServerInformation.aspx',
   4:             tite: 'Server Information',
   5:             allowMaximize: false,
   6:             showClose: true,
   7:             width: 430,
   8:             height: 230
   9:         };
  10:
  11:         SP.UI.ModalDialog.showModalDialog(options);
  12:         return false;
  13:     }

How to fix this problem

1. Remove the Java Script reference.
   <script src=”/_layouts/sp.js” type=”text/javascript”></script>
   <script src=”/_layouts/SP.UI.Dialog.js” type=”text/javascript”></script>
2. Add to the url variable “?IsDlg=1″`
3. Replace the command SP.UI.ModalDialog.showModalDialog() with the new command SP.SOD.execute(‘sp.ui.dialog.js’, ‘SP.UI.ModalDialog.showModalDialog’, options);

With this few changes your solution will work correctly.

SharePoint 2013 Example:

   1: function ShowServerInformation(featureId) {
   2:       var options = {
   3:           url: '/_admin/Solutions2Share/LicenseManagement/ServerInformation.aspx?featureId=' + featureId + "&IsDlg=1",
   4:           title: 'Server Information',
   5:           allowMaximize: false,
   6:           showClose: true,
   7:           width: 430,
   8:           height: 230
   9:       };
  10:
  11:       SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
  12:
  13:       return false;
  14:   }
