问题 I am looking for some help with my code I have so far. The main objective is to be able to click on any Plus icon and have it place a cover over all other div blocks. And when a plus icon is clicked it will also show a div block to the right. As you will see when block 2 is clicked it does all that is intended. I am looking for an efficient way to do this with Angular when any plus icon is clicked. This is just a small sample I show here, in reality there would be 10 to 20 blocks to cover. If

AngularJS, difference between ng-class and class with angular expression?

阅读更多关于 AngularJS, difference between ng-class and class with angular expression?

问题 What is the difference between the following two code snippets, Code 1: <div class={{getClass()}}/> Code 2: <div ng-class=getClass()/> 回答1: With the first example before angular loads your class will literally be "{{getClass()}}". While in the second example the div won't have a class until angular runs its first digest. There might be some minor differences with when they are recalculated but Angular will keep both up to date. I've run into issues before using the first method with Animation
