這篇文章主要介紹了AngularJS ng-repeat指令及Ajax的應(yīng)用,結(jié)合實例形式分析了ng-repeat指令的功能及ajax請求交互相關(guān)操作技巧,需要的朋友可以參考下

本文實例講述了AngularJS ng-repeat指令及Ajax的應(yīng)用。分享給大家供大家參考，具體如下：

ng-repeat 指令用于循環(huán)輸出指定次數(shù)的 HTML 元素。集合必須是數(shù)組或?qū)ο蟆?/span>

定義：

<element ng-repeat="expression"></element>

說明：experssion表達(dá)式定義了如何循環(huán)集合。常用的如：x in records

下面通過一個例子,來說明ng-repeat如何繪制一個表格：

<div ng-app='mainApp' ng-controller='studentController'>
  <table border="0">
    <tr>
      <td>姓</td>
      <td><input type="text" ng-model='student.firstName'></td>
    </tr>
    <tr>
      <td>名</td>
      <td><input type="text" ng-model='student.lastName'></td>
    </tr>
    <tr>
      <td>名字</td>
      <td>{{student.fullName()}}</td>
    </tr>
    <tr>
      <td>科目</td>
      <td>
        <table>
          <tr>
            <th>名字</th>
            <th>標(biāo)記</th>
          </tr>
          <tr ng-repeat='sub in student.subjects'>
            <td>{{sub.name}}</td>
            <td>{{sub.marks}}</td>
          </tr>
        </table>
      </td>
    </tr>
  </table>
</div>

表可以使用CSS樣式設(shè)置樣式。

<style>
  table, th , td {
    border: 1px solid grey;
    border-collapse: collapse;
    padding: 5px;
  }
  table tr:nth-child(odd) {
    background-color: #f2f2f2;
  }
  table tr:nth-child(even) {
    background-color: #ffffff;
  }
</style>

利用angularjs的ng-repeat指令繪制表格:

<script>
  var mainApp=angular.module('mainApp',[]); //定義一個名為mainApp的模塊
  mainApp.controller('studentController',function($scope){
    $scope.student={
      firstName:'聶',
      lastName:'鵬飛',
      subjects:[
      {name:'物理',marks:73},
          {name:'化學(xué)',marks:90},
          {name:'數(shù)學(xué)',marks:68},
          {name:'英文',marks:85},
          {name:'生物',marks:77},
      ],
      fullName:function(){
        var studentObject;
        studentObject = $scope.student;
        return studentObject.firstName+' '+studentObject.lastName;
      }
    };
  });
</script>

效果：

上面例子表格中展示的數(shù)據(jù)也可以通過ajax請求從服務(wù)器中獲取，然后利用ng-repeat指令插入到頁面中，具體實現(xiàn)見下面代碼:

<html>
<head>
<title>Angular JS Controller</title>
<script src="angularjs/angular-1.3.0/angular.min.js"></script>
<style>
  table, th , td {
    border: 1px solid grey;
    border-collapse: collapse;
    padding: 5px;
  }
  table tr:nth-child(odd) {
    background-color: #f2f2f2;
  }
  table tr:nth-child(even) {
    background-color: #ffffff;
  }
</style>
</head>
<body>
  <h2>AngularJS 表格應(yīng)用示例</h2>
  <div ng-app='mainApp' ng-controller='studentController'>
    <table border="0">
      <tr>
        <td>姓</td>
        <td><input type="text" ng-model='student.firstName'></td>
      </tr>
      <tr>
        <td>名</td>
        <td><input type="text" ng-model='student.lastName'></td>
      </tr>
      <tr>
        <td>名字</td>
        <td>{{student.fullName()}}</td>
      </tr>
      <tr>
        <td>科目</td>
        <td>
          <table>
            <tr>
              <th>名字</th>
              <th>標(biāo)記</th>
            </tr>
            <tr ng-repeat='sub in student.subjects'>
              <td>{{sub.name}}</td>
              <td>{{sub.marks}}</td>
            </tr>
          </table>
        </td>
      </tr>
    </table>
  </div>
  <script>
    var mainApp=angular.module('mainApp',[]);
    mainApp.controller('studentController',function($scope,$http){
      $scope.student={
        firstName:'聶',
        lastName:'鵬飛',
        fullName:function(){
          var studentObject;
          studentObject = $scope.student;
          return studentObject.firstName+' '+studentObject.lastName;
        },
      };
      var url="data.txt";
      $http.post(url).success(function(response){
        $scope.student.subjects=response;
      })
    });
  </script>
</body>
</html>

說明：需要放在服務(wù)器環(huán)境中運(yùn)行
