How do you disable the submit button after a single click to prevent multiple submissions in Angularjs?

ng-show when array length is zero

by

If you’re filtering in your ng-repeat, you must apply the same filter for you ng-show. If you don’t, the ng-show will always refer to the full array : <div ng-show=”!(tags| filter:nameText).length”>No Tag Found</div> Working fiddle : http://jsfiddle.net/HB7LU/3149/
