极客无极限 一行HTML5代码引发的创意大爆炸
- - CSS库国外开发者Jose Jesus Perez Aguinaga写了一行HTML5代码的文本编辑器. 这件事在分享到Code Wall、Hacker News之后,引起了众多开发者的注意,纷纷发表了自己的创意. 这是最初的HTML5代码,它可以运行在最新的Chrome和Firefox中,只需在浏览器地址栏输入如下代码:.
但是功能十分有限,甚至没有保存功能,样式也非常简陋。 于是,网友Montas修改了他的代码,使用textarea标签代替html标签,可以添加自己喜欢的样式:data:text/html, <
html
contenteditable>
网友jecxjo希望能有存储功能:data:text/html, <
textarea
style
=
"font-size: 1.5em; width: 100%; height: 100%; border: none; outline: none"
autofocus />
但上面的代码是以文件形式存储,samsonjs觉得不够方便,而且需要点击按钮,于是添加了自动保存功能:data:text/html,<
button
onClick
=
"SaveTextArea()"
>Save</
button
> <
script
language
=
"javascript"
type
=
"text/javascript"
> function SaveTextArea() { window.location = "data:application/octet-stream," + escape(txtBody.value); } </
script
> <
textarea
id
=
"txtBody"
style
=
"font-size: 1.5em; width: 100%; height: 100%; boarder: none; outline: none"
autofocus> </
textarea
>
现在可是云时代!仅仅这样怎能让开发者止步?minikomi使用了第三方API打造了一个在线编辑器:data:text/html,<
html
lang
=
"en"
><
head
><
style
> html,body { height: 100% } #note { width: 100%; height: 100% } </
style
> <
script
> var note, html, timeout; window.addEventListener('load', function() { note = document.getElementById('note'); html = document.getElementsByTagName('html')[0]; html.addEventListener('keyup', function(ev) { if (timeout) clearTimeout(timeout); timeout = setTimeout(saveNote, 100); }); restoreNote(); note.focus(); }); function saveNote() { localStorage.note = note.innerText; timeout = null; } function restoreNote() { note.innerText = localStorage.note || ''; } </
script
> </
head
><
body
><
h1
>Notepad (type below, notes persist)</
h1
> <
p
id
=
"note"
contenteditable
=
""
></
p
> </
body
></
html
>
data:text/html, <style type="text/css"> #e { position:absolute; top:0; right:0; bottom:0; left:0; font-size:16px; } </style> <div id="e"></div> <script src="http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js"></script> <script src="http://code.jquery.com/jquery-1.9.0.min.js"></script> <script> var myKey="SecretKeyz"; $(document).ready(function(){ var e; var url = "http://api.openkeyval.org/"+myKey; $.ajax({ url: url, dataType: "jsonp", success: function(data){ e = ace.edit("e"); e.setTheme("ace/theme/tomorrow_night_eighties"); e.getSession().setMode("ace/mode/markdown"); e.setValue(data); } }); $("#e").on("keydown", function (b) { if (b.ctrlKey && 83 == b.which) { b.preventDefault(); var data = myKey+"="+encodeURIComponent(e.getValue()); $.ajax({ data: data, url: "http://api.openkeyval.org/store/", dataType: "jsonp", success: function(data){ alert("Saved."); } }); } }); }); </script>没有代码高亮功能的编辑器终究不适合程序员,Rails开发者jakeonrails又定制了Ruby代码高亮功能:
效果如下图: 实际上,如果minikomi的代码已经支持多种语言高亮,如Python,只需要把“markdown”换成“python”,效果如下: 你以为到此为止了?中国开发者assassindesign觉得只是文本编辑器就太无聊了,又提供了涂鸦版本:data:text/html, <style type=
"text/css"
>
#e{position:absolute;top:0;right:0;bottom:0;left:0;}</style><div id="e"></div><script src=" http://d1n0x3qji82z53.cloudfront.net/src-min-noconflict/ace.js" type="text/javascript" charset="utf-8"></script><script>var e=ace.edit("e");e.setTheme("ace/theme/monokai");e.getSession().setMode("ace/mode/ruby");</script>
还等什么呢?赶快试试看吧! 极客的创意的无穷的,你们是否有更好的创意,欢迎跟帖!data:text/html, <
