妙用Angularjs实现表格按指定列排序
使用AngularJS的过滤器,可以很容易的实现在表格中,点击某一列标题进行排序,实现过程如下:
html代码:
<table class="table table-border" ng-app="myapp" ng-controller="orderByCtrl"> <thead> <tr> <th>inx</th> <th ng-click="col='name';desc=!desc">name</th> <!-- 当点击列标题时,执行click事件,将排序条件反转,即,如果原来是升序则将按降序,降序亦如此 --> <th ng-click="col='gender';desc=!desc">gender</th> <th ng-click="col='age';desc=!desc">age</th> <th ng-click="col='score';desc=!desc">score</th> </tr> </thead> <tbody> <tr ng-repeat="d in data|orderBy:col:desc"> <td ng-bind="$index+1"></td> <td ng-bind="d.name"></td> <td ng-bind="d.gender"></td> <td ng-bind="d.age"></td> <td ng-bind="d.score"></td> </tr> </tbody> </table>
js代码:
var app = angular.module('myapp', []); app.controller('orderByCtrl', function($scope) { $scope.col = 'name';//默认按name列排序 $scope.desc = 0;//默认排序条件升序 $scope.data = [{ name: 'name 1', gender: 'male', age: 26, score: 70 }, { name: 'name 2', gender: 'female', age: 24, score: 84 }, { name: 'name 3', gender: 'male', age: 20, score: 76 }, { name: 'name 4', gender: 'female', age: 22, score: 64 }]; })
让运行界面好看些,使用了bootstrap.min.css样式库。为了交互性考虑,在表头增加了手指样式
th { cursor: pointer; }
