在AngularJS中用于返回
true
如果引用是数组, 并且
false
如果不是数组。
语法如下：
angular.isArray(value)返回值：如果该值是一个数组, 则返回TRUE, 否则将返回FALSE。
范例1：
< html >
< head >
< title >angular.isArray()</ title >
< script src =
"https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js" >
</ script >
</ head >
< body ng-app = "app" style = "text-align:Center" >
< h1 style = "color:green" >lsbin</ h1 >
< h2 >angular.isArray()</ h2 >
< div ng-controller = "geek" >
< b >Sorting Algos:</ b >
< div ng-repeat = "i in sort" >{{i.name}}</ div >
< br >< br >
isArray: {{isArray}}
</ div >
< script >
var app = angular.module("app", []);
app.controller('geek', ['$scope', function ($scope) {
$scope.sort = [];
var values = [
{ name: 'Merge sort' }, { name: 'Quick sort' }, { name: 'Bubble sort' }
];
if (angular.isArray(values)) {
$scope.isArray = true;
angular.forEach(values, function (value, key) {
$scope.sort.push(value)
})
}
}]);
</ script >
</ body >
</ html >输出如下：
范例2：
<!DOCTYPE html>
< html >
< head >
< title >angular.isArray()</ title >
< script src =
"https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js" >
</ script >
</ head >
< body ng-app = "app" style = "text-align:Center" >
< h1 style = "color:green" >lsbin</ h1 >
< h2 >angular.isArray()</ h2 >
< div ng-controller = "geek" >
< b >Input: </ b >{{name}}
< br >< br >
< b >isArray:</ b > {{isArray}}
</ div >
< script >
var app = angular.module("app", []);
app.controller('geek', ['$scope', function ($scope) {
var values = 'lsbin';
$scope.name = values;
$scope.isArray = angular.isArray(values)
}]);
</ script >
</ body >
</ html >输出如下：
