你想经过网络完毕做完毕实吧？现在您只须求 10 行 HTML
代码！真的！让自己带您看一看代码，格外简单。

咱俩近年来发表了AR.js。你不要求设置任何利用，用你的无绳电话机通过网络就能感受到无敌的增高现实。但让我们更进一步，看一下哪些让你也撰写出团结的增进现实感受。多亏了神奇的a-frame，最短的
AR.js 只有 10 行 HTML
代码。你可以在codepen来看在线版：

第三章 jQuery中的DOM操作，jquerydom

　　DOM(Document Object
Model)文档对象模型，每张网页都能用DOM表示出来，每一份DOM都能作为一颗DOM树。

　　jQuery继承了JavaScript对DOM对象操作的性状，使开发人士能有益地操作DOM对象。

<script>THREEx.ArToolkitContext.baseURL = ‘https://rawgit.com/jeromeetienne/ar.js/master/three.js/'</script>

率先，你必要引入a-frame，一款MozillaVR引领的花费VR 体验的利器。A-frame 包罗了 three.js。然后你只要求为 a-frame 引入
AR.js。AR.js能让 AR 中的 3d 呈现在您的手机上高速运行，哪怕是 2、3
年前的旧手机。

俺们多年来公布了AR.js。你不须要设置任何利用，用你的手机通过网络就能感受到有力的增高现实。但让大家更进一步，看一下哪些让您也撰文出团结的滋长现实感受。多亏了神奇的a-frame，最短的
AR.js只有10行HTML 代码。

对此jquery一些标题

哇哦，我帮您写代码：
<script type=”text/javascript”>
$(function(){
$(“.has_children”).click(function(){
$(this).addClass(“highlight”)
.children(“a”).show().end()
.siblings().removeClass(“highlight”)
.children(“a”).hide();
});

});

<body style=’margin : 0px; overflow: hidden;’>

看出来去其余呢？一定要加在：
$(function(){ })
的函数内。

您之所以没意义，是因为你绑定事件的时候 ，dom 节点根本不设有。
而 $(function(){ }) 这些函数的情致是，当 所有 html

增加简单的始末

XHTML

<a-box position=’0 0.5 0′ material=’opacity: 0.5;’></a-box>

1
<a-box position=’0 0.5 0′ material=’opacity: 0.5;’></a-box>

假诺大家创立了 3d
场景，大家可以起来向其中添加对象。在那行代码中，大家添加了一个简短的盒子。然后大家修改了它的材质，让它变得透明。大家也转移了它的岗位，所以它出现在
AR 标识（AR marker）的下面。

jQuery：那里是怎完结？原代码没看懂

您那段代码中jquery只是拍卖了，<span>的click事件。
当click发生时，只突显大标题，并且点击了哪个大标题，就会显示其下相应的小标题。

有关为什么一进入页面就显得大标题，可能跟你的css有关系吗。
 

jQuery中的DOM操作，jquerydom DOM(Document
Object
Model)文档对象模型，每张网页都能用DOM表示出来，每一份DOM都能看做一颗DOM树。
jQuery继承…

                            }
                        },
                        tickColor: ‘#000000’,
                        tickLength: 5,
                        tickWidth: 1,
                        dateTimeLabelFormats: {
                            day: ‘%Y-%m-%d’,
                            week: ‘%Y-%m-%d’,
                            month: ‘%Y-%m-%d’,
                            year: ‘%Y-%m-%d’
                        },
                        title: {
                            style:
                      {
                          display: ‘none’
                      }
                        }

增加 AR 摄像头

XHTML

<a-marker-camera preset=’hiro’></a-marker-camera>

1
<a-marker-camera preset=’hiro’></a-marker-camera>

在结尾一步，我们伸张一个视频头。大家预设一个 ‘hiro’（来自Hiro
marker）最后，我们让它像您手机同样移动。是否很简短？

恭喜！你完了了。你仅用了 10 行 HTML
代码完毕了增强现实，手机上也能运作高效，而且免费。

可以看一下自身做的视频教程（搬运自youtube，字幕为 youtube
自动识别内嵌字幕，有微量识别误差，不影响观望）：

这一步，国际惯例。就好像您在享有 HTML 页面中做的如出一辙，定义 body。

                });
            });

创建 3d 场景。

        });
    </script>
</head>
<body>
    <script src=”Lib/Highcharts-2.2.5/js/highcharts.js”
type=”text/javascript”></script>
    <!– <script
src=”../../js/modules/exporting.js”></script>–>
    <div id=”bg” style=”margin: 0; padding: 0;”>
        <div style=”width: 736px; margin: 0 auto; height: 27px;
line-height: 27px; font-family: Microsoft YaHei;

接下来，大家就要制造大家的 a-farme 场景。大家本来也急需进入 ARToolkit
组件。ARToolkit是一个开源库，大家透过它来落实视频头定位。

运转效果：

倘诺大家成立了 3d
场景，大家得以先河向里面添加对象。在那行代码中，我们添加了一个简易的盒子。然后我们修改了它的材料，让它变得透明。我们也改成了它的任务，所以它出现在
AR 标识（AR marker）的上方。

在最后一步，大家扩大一个视频头。大家预设一个
‘hiro’最终，大家让它像你手机一样移动。是或不是很粗略？

恭贺！你做到了。你仅用了 10
行html代码完成了增强现实，手机上也能运作高效，而且免费。
