效果截图：
说明：引入bootstrap.min.css样式库和angular.min.js的静态资源库，实现列表内容的增加和删除操作。
AngularJS代码：
<script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
<script>
angular.module('myapp',[])
.controller('myctrl',function($scope){
$scope.item = '';
$scope.items = [];
//增加列表项方法
$scope.add = function(){
$scope.items.push($scope.item);
}
})
</script>
HTML代码：
<!DOCTYPE html>
<html lang="en" ng-app="myapp">
