js使用video标签当切换视频时会显示上一个视频的,第1张

js使用video标签当切换视频时会显示上一个视频是video标签没有改。如果直接把标签替换掉的话，第一次是可以播放，但再切换别的src还是会显示第一个播放的视频的src。所以，正确方法是连同video标签一起换了。

代码如下：

<!doctype html>

<html lang="en">

<head>

<meta charset="UTF-8">

<title>tab标签切换效果</title>

<style>

*{ margin:0padding:0list-style: none}

body {font:12px/1.5 Tahoma}

#outer {width:450pxmargin:150px auto}

#tab {overflow:hiddenzoom:1background:#000border:1px solid #000}

#tab li {float:leftcolor:#fffheight:30px cursor:pointer line-height:30pxpadding:0 20px}

#tab li.current {color:#000background:#ccc}

#content {border:1px solid #000border-top-width:0}

#content ul {line-height:25pxdisplay:none margin:0 30pxpadding:10px 0}

</style>

</head>

<body>

<!-- html代码begin -->

<div id="outer">

<ul id="tab">

<li class="current">tab标签</li>

<li>qq在线客服代码</li>

<li>css3</li>

</ul>

<div id="content">

<ul style="display:block">

<a href="">tab标签</a>

</ul>

<ul>

<a href="">服代码</a>

</ul>

<ul>

<a href="">css</a>

</ul>

</div>

</div>

<!-- html代码end -->

<script src="jquery.min.js"></script>

<script>

angularjs中tab标签切换的实现方法如下：

1、定义div容器：

<div ng-app="TabsApp">

<div id="tabs" ng-controller="TabsCtrl">

<ul>

<li ng-repeat="tab in tabs"

ng-class="{active:isActiveTab(tab.url)}"

ng-click="onClickTab(tab)">{{tab.title}}</li>

</ul>

<div id="mainView">

<div ng-include="currentTab"></div>

</div>

</div>

<script type="text/ng-template" id="one.tpl.html">

<div id="viewOne">

<h1>View One</h1>

<p>Praesent id metus massa, ut blandit odio. Proin quis tortor orci. Etiam at risus et justo dignissim congue. Donec congue lacinia dui, a porttitor lectus condimentum laoreet. Nunc.</p>

</div>

</script>

<script type="text/ng-template" id="two.tpl.html">

<div id="viewTwo">

<h1>View Two</h1>

<p>Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu.</p>

</div>

</script>

<script type="text/ng-template" id="three.tpl.html">

<div id="viewThree">

<h1>View Three</h1>

<p>In pellentesque faucibus vestibulum. Nulla at nulla justo, eget luctus tortor. Nulla facilisi. Duis aliquet egestas purus in blandit. Curabitur vulputate, ligula lacinia scelerisque tempor, lacus lacus ornare ante, ac egestas est urna sit amet arcu. Class aptent taciti sociosqu.</p>

</div>

</script>

</div>

2、angularjs实现方法：

angular.module('TabsApp', [])

.controller('TabsCtrl', ['$scope', function ($scope) {

$scope.tabs = [{

title: 'One',

url: 'one.tpl.html'

}, {

title: 'Two',

url: 'two.tpl.html'

}, {

title: 'Three',

url: 'three.tpl.html'

}]

$scope.currentTab = 'one.tpl.html'

$scope.onClickTab = function (tab) {

$scope.currentTab = tab.url

}

$scope.isActiveTab = function(tabUrl) {

return tabUrl == $scope.currentTab

}

}])
