本文实例讲述了AngularJS实现的生成随机数与猜数字大小功能。分享给大家供大家参考,具体如下:

<!DOCTYPE html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>www.jb51.net Angular猜数</title>
 <style>
  *{
   margin: 0;
   padding: 0;
   font-size: 30px;
  }
  input{
   width: 500px;
   height: 50px;
   font-size: 30px;
  }
  button{
   width: 80px;
   height: 50px;
   border: 0;
   text-align: center;
   line-height: 50px;
   background: darkblue;
   color: #fff;
   margin-left: 5px;
  }
 </style>
 <script src="angular/angular.js"></script>
 <script>
  var myapp=angular.module("myapp",[]);
  myapp.controller("myCtrl",function ($scope) {
    $scope.check=function () {
     console.log($scope.random);
     $scope.differ=$scope.guess-$scope.random;
     $scope.num++;
    };
    $scope.reset=function () {
     $scope.differ=null;
     $scope.guess=null;
     $scope.num=0;
     $scope.random=Math.ceil(Math.random()*10);
    };
    $scope.reset();
  })
 </script>
</head>
<body ng-app="myapp" ng-controller="myCtrl">
<h2>请输入一个1-10的整数</h2>
<input type="text" ng-model="guess"><button ng-click="check()">检查</button><button ng-click="reset()">重置</button>
<p ng-if="differ>0">猜大了</p>
<p ng-if="differ<0">猜小了</p>
<p ng-if="differ==0">猜对了</p>
<p>一共猜了<span ng-bind="num"></span>次</p>
</body>
</html>

运行效果:
