I could just in a 2-way binded value, but then I wouldn't be able to use a ng-change in the parent directive on the child element. I could also use ng-click, but this wouldn't work with a non-clicking change (such as a text area instead of a checkbox). So I'm wondering if there's a way to allow a custom directives to have a ng-model/ng-change

Is there any way to force angular to process these updates app.js After a time-out of 5secs, the value 1 is changed to 999. This is reflected in html but not in $scope.val angular.module('inputExample', []) .controller('ExampleController', ['$scope', '$timeout'

Dynamically creating multiple dropdown and auto setting each dropdown in angularjs

由 谁说我不能喝 提交于 2019-12-13 05:03:12
问题 I was able to dynamically creating multiple drop-down lists base on the same set of data in angularJS. However, I am having an issue trying to dynamically set the default value of each of the drop-down lists. For example, in my first drop-down list, I would like the first subject ("Writing") to be selected by default. Then I would like the second drop-down list to have the second subject ("Reading") to be selected and the third drop-down list to have the third subject ("Math") to be selected
