Do you know how to disable that the page is posted when the enter key is pressed ?
I am using jqxwidgets in a sharepoint site, but when I add the jqxInput once that I hit enter and the jqxInput has the focus, the page is posted and opened in Edit mode.
Unfortunately, we do not have any experience with SharePoint and will not be able to help you with that.
If you would like to look at this theme could be helpful.
