Angularjs encounters an abrupt stop in the expression during an ng-keypress event

In my code, I am utilizing the ng-keypress directive to monitor whether the ENTER key has been pressed.

...
...
<input type="text" ng-model="mymodal"
    ng-keypress="($event.charCode==13)?myFunction():return"/>

...
...

However, upon opening the page in Chrome, an error is encountered:

Error: [$parse:ueoe] Unexpected end of expression: ($event

<input type="text" ng-model="mymodal" ng-keypress="($event.charCode==13)?myFunction():return" class="ng-pristine ng-untouched ng-valid">

If ng-keypress is removed or replaced with an empty string "", the issue does not persist.

Answer №1

If your goal is to only activate your function when the Enter key is pressed, you can achieve this using the code snippet below:

ng-keypress="$event.charCode === 13 && myFunction()"
