Ng-hide和last：child CSS

Question

I have;

<div class="exampleDiv">
    <element1></element1>
    <element2></element2>
    <element3></element3>
</div>

then some CSS using the last:child selector (only margin-right:0 FYI). However I use a conditional ng-hide on elements 1-3 and so if element3 is hidden, the last:child CSS is not moved to element2 as technically it is rendered in the DOM then hidden.

So I was wondering is there a way to use ng-hide and have something like a 'last-visible-element' selector. So that as ng-hide does its work, the last element the user can see has this CSS applied to it?

Thanks for any help in advance!

Answer 1

is remove() what you look for since it does remove element from the dom tree:

 var myApp = angular.module("myApp", []); myApp.controller("myController", function($scope) { $scope.removeElement = function() { var elmn = angular.element( document.querySelector( '.test :last-child' ) ); elmn.remove(); }; }); 

 .test { display: flex; justify-content: space-between; } .test div { border: solid; min-width: 5em; } .test :last-child { color: red; } .test :last-child:before { content:"actual last-child "; color:green; } 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div ng-app="myApp"> <p>each time you click, last element is removed</p> <div ng-controller="myController" class="test"> <input type="button" value="Remove Div " ng-click="removeElement()"> <div>1</div> <div>2</div> <div>3</div> <div>4</div> <div>last-child</div> </div> </div>

Answer 2

you may try adding dynamic class based on some condition , something like :-

css / style

.show {
    display: inline;
}
.hide {
    display: none;
}

script

<div class="exampleDiv">
   <element1 ng-class="{'show' : item.isVisible == true, 'hide' : item.isVisible == false}"></element1>
   <element2 ng-class="{'show' : item.isVisible == true, 'hide' : item.isVisible == false}"></element2>
   <element3 ng-class="{'show' : item.isVisible == true, 'hide' : item.isVisible == false}"></element3>
</div>
