AngularJS API实例
AngularJS API实例，AngularJS API用于比较、迭代和转换对象。基本AngularJS API包括
- angular.isString()
- angular.lowercase()
- angular.uppercase()
- angular.isNumber()
1. angular.isString()
用于检查对象是否为字符串，如果对象为字符串则返回true，否则返回false。
例子：
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">
</script>
</head>
<body>
<div ng-app="gfg" ng-controller="gfgCntrl">
<p>{{ object }}</p>
<p>{{ apiRes }}</p>
</div>
<script>
var app = angular.module('gfg', []);
app.controller('gfgCntrl', function($scope) {
$scope.object = "GeeksForGeeks";
$scope.apiRes = angular.isString($scope.object);
});
</script>
</body>
</html>输出：
2. angular.lowercase()
用于将字符串转小写
例子：
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">
</script>
</head>
<body>
<div ng-app="gfg" ng-controller="gfgCntrl">
<p>{{ object }}</p>
<p>{{ apiRes }}</p>
</div>
<script>
var app = angular.module('gfg', []);
app.controller('gfgCntrl', function($scope) {
$scope.object = "GeeksForGeeks";
$scope.apiRes = angular.lowercase($scope.object);
});
</script>
</body>
</html>输出：
3. angular.uppercase()
用于将字符串转大写。
例子：
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">
</script>
</head>
<body>
<div ng-app="gfg" ng-controller="gfgCntrl">
<p>{{ object }}</p>
<p>{{ apiRes }}</p>
</div>
<script>
var app = angular.module('gfg', []);
app.controller('gfgCntrl', function($scope) {
$scope.object = "GeeksForGeeks";
$scope.apiRes = angular.uppercase($scope.object);
});
</script>
</body>
</html>输出：
4. angular.isNumber()
用于检查对象是否为数字。如果 object 是数字，则返回 true，否则返回 false。
例子：
<!-- Write HTML code here -->
<!DOCTYPE html>
<html>
<head>
<script src=
"https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js">

<body>
<div ng-app="gfg" ng-controller="gfgCntrl">
<p>{{ object }}</p>
<p>{{ apiRes }}</p>
</div>
<script>
var app = angular.module('gfg', []);
app.controller('gfgCntrl', function($scope) {
$scope.object = "GeeksForGeeks";
$scope.apiRes = angular.isNumber($scope.object);
});
</script>
</body>
</html>输出：
