Angular实现的进度条功能示例

本文实例讲述了Angular实现的进度条功能。分享给大家供大家参考,具体如下:

项目里需要一个进度条,所以就在网上查找资料学习,看到了网友“雪狼”的代码分享,写的很高明,很精练,很厉害,原文中的代码如下:

HTML部分:

<div ng-class="{progress: true, 'progress-striped': vm.striped}">

<div ng-class="['progress-bar', vm.style]" ng-style="{width: vm.value + '%'}">

<div ng-if="vm.showLabel">{{vm.value}}%</div>

</div>

</div>

<h3>选项</h3>

<label>进度:<input type="number" class="form-control" ng-model="vm.value"/></label>

<button class="btn btn-primary" ng-click="vm.value=0">0%</button>

<button class="btn btn-primary" ng-click="vm.value=20">20%</button>

<button class="btn btn-primary" ng-click="vm.value=60">60%</button>

<button class="btn btn-primary" ng-click="vm.value=100">100%</button>

<hr/>

<label>斑马纹<input type="checkbox" ng-model="vm.striped"/></label>

<label>文字<input type="checkbox" ng-model="vm.showLabel"/></label>

<hr/>

<label>风格:

<select ng-model="vm.style" class="form-control">

<option value="progress-bar-success">progress-bar-success</option>

<option value="progress-bar-info">progress-bar-info</option>

<option value="progress-bar-danger">progress-bar-danger</option>

<option value="progress-bar-warning">progress-bar-warning</option>

</select>

</label>

JS部分:

'use strict';

angular.module('ngShowcaseApp').controller('ctrl.show.progress', function ($scope) {

var vm = $scope.vm = {};

vm.value = 50;

vm.style = 'progress-bar-info';

vm.showLabel = true;

});

这里结合自己的项目需要,自己改编了个简单的进度条,可以加在项目里面,进度条的开始和结束由自己决定。

1. js代码

var myApp = angular.module('myApp', []);

myApp.controller('main', ['$scope', '$interval', function($scope, $interval){

var vm = $scope.vm = {};

vm.value = 0;

vm.style = 'progress-bar-danger';

vm.showLabel = true;

vm.striped = true;

$scope.selectValue = function (){

console.log(vm.style);

};

var index = 0;

var timeId = 500;

$scope.count = function(){

var start = $interval(function(){

vm.value = ++index;

if (index > 99) {

$interval.cancel(start);

}

if (index == 60) {

index = 99;

}

}, timeId);

};

}]);

2. html代码

<div ng-class="{progress: true, 'progress-striped': vm.striped}" class="col-md-4">

<div ng-class="['progress-bar', vm.style]" ng-style="{width: vm.value + '%'}">

<div ng-if="vm.showLabel">{{vm.value}}%</div>

</div>

</div>

<button class="btn btn-success" ng-click="count()">开始进度</button>
