SP.UI.ModalDialog.showModalDialog() do not work under SharePoint 2013
Introduction
Have you ever tried using the SP.UI.ModalDialog.showModalDialog(options) in SharePoint 2013. I did and I discovered some strange behavior.
After migrating my code from the SharePoint 2010 to SharePoint 2013, the calls to the showModalDialog failed with a message that the method cannot be found (javascript). I checked it in the IE Developer Tools and somehow it wasn’t surprising at all; it said that the required js-file isn’t loaded.
But why? I guess it must be the new SOD-Model (Script on Demand) that got introduced in the SharePoint 2013.
SharePoint 2010 Example
function ShowServerInformation() {
var options = {
url: '/_layouts/Management/GeneralInformation.aspx',
tite: 'Management Information',
allowMaximize: false,
showClose: true,
width: 430,
height: 230
};
SP.UI.ModalDialog.showModalDialog(options);
return false;
}
It’s very easy to fix this problem.
- 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>
- Add to the url variable "?IsDlg=1"`
- Replace the command SP.UI.ModalDialog.showModalDialog() with the new command SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
After making the changes your solution will work nicely.
SharePoint 2013 Example
function ShowServerInformation(featureId) {
var options = {
url: '/_layouts/Management/GeneralInformation.aspx?IsDlg=1',
tite: 'Management Information',
allowMaximize: false,
showClose: true,
width: 430,
height: 230
}
SP.SOD.execute('sp.ui.dialog.js', 'SP.UI.ModalDialog.showModalDialog', options);
return false;
}
Notice: Initially I tried the “executeOrDelayUntilScriptLoaded”-function but it was of no help. It only “swallowed” my function call and never executed it, because the js-file, I specified, was never loaded.
