AngularJS APIs are used for comparing, iterating and converting objects.Basic AngularJS API includes
- angular.isString()
- angular.lowercase()
- angular.uppercase()
- angular.isNumber()
1. angular.isString()
It is used to check whether an object is a string or not.It returns true if the object is string otherwise false.
Example:
<!DOCTYPE html>
< html >
< head >
< script src =
</ 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 >
|
Output:
2. angular.lowercase()
It is used to convert all the characters of the string into lowercase characters.
Example:
<!DOCTYPE html>
< html >
< head >
< script src =
</ 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 >
|
Output:
3. angular.uppercase()
It is used to convert all the characters of the string into uppercase characters.
Example:
<!DOCTYPE html>
< html >
< head >
< script src =
</ 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 >
|
Output:
4. angular.isNumber()
It is used to check whether an object is a number or not. It returns true if object is a number otherwise false.
Example:
<!DOCTYPE html>
< html >
< head >
< script src =
</ 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";
$scope.apiRes = angular.isNumber($scope.object);
});
</ script >
</ body >
</ html >
