AngularJS中的angular.equals()函数用于比较两个对象或两个值,无论它们是否相同。如果两个值相同,则返回TRUE,否则将返回FALSE。
用法:
angular.equals(val1, val2)
其中val1和val2是要比较的值或对象。返回值:返回TRUE或FALSE
范例1:
<html>
<head>
<script src=
"//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js">
</script>
<title>angular.equals()</title>
</head>
<body ng-app="app" style="text-align:Center">
<h1 style="color:green">GeeksforGeeks</h1>
<h2>angular.equals()</h2>
<div ng-controller="geek">
Input A:<input type="number" ng-model="val1" ng-change="check()" />
<br /><br>
Input B:<input type="number" ng-model="val2" ng-change="check()" />
<br /><br>
{{msg}}
</div>
<script>
var app = angular.module("app", []);
app.controller('geek', ['$scope', function ($scope) {
$scope.val1 = 0;
$scope.val2 = 0;
$scope.check = function () {
if (angular.equals($scope.val1, $scope.val2))
$scope.msg = "Input values are equal.";
else
$scope.msg = "Input values are not equal.";
}
}]);
</script>
</body>
</html>
