I'm trying to enhance an element with the following ng-class attributes:
<div ng-class="a ? 'class1' : 'class2'"></div>ng-class="class3: b !== c".
How can I merge these ng-class statements effectively?
I've attempted <div ng-class="{a ? 'class1' : 'class2, class3: b !== c"></div><div ng-class="(a ? 'class1' : 'class2') + ' ' + (class3: b !== c)"></div>I personally prefer using a specific syntax for ng-class in order to clearly indicate which classes are being added, rather than relying on the ternary operator:
<div ng-class="{'class1' : a, 'class2' : !a, 'class3': b !== c }"></div>
Alternatively, if you prefer using the ternary operator, you can do so like this:
<div ng-class="(a ? 'class1' : 'class2') + ' ' + (b !== c ? 'class3': '' )></div>
The reason your solutions may not have worked is likely because you attempted to mix the two different syntax styles (with and without curly brackets).
It is possible to achieve this without using a ternary operator by utilizing the following code snippet.
<div ng-class="{'class1' : a, 'class2' : !a, 'class3': b !== c }"></div>
var app = angular.module('exApp', []);
app.controller('ctrl', function($scope){
$scope.a = 1;
$scope.c = 10;
$scope.b = 89;
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.3/angular.min.js"></script>
<style>
.class1{
font-size:18px;
}
.class2{
color:orange;
}
.class3{
color:blue;
}
</style>
<body ng-app="exApp" ng-controller="ctrl">
<p ng-class="a ? 'class1' : 'class2'">Hi..Used Ternary Operator</p>
<p ng-class="{'class3': b !== c, 'class1' : !a, 'class2':a, }">Hi!...Without Ternary Operator</p>
</body>ng-class=" {className1: checkIftrue, className2: otherCondition}"
