1. Skulpt是一个完全依靠浏览器端模拟实现Python运行的工具

2. 不需要预处理、插件或服务器端支持,只需编写python并重新载入即可。

3. 由于代码完全是在浏览器中运行的,所以不必担心“服务器崩溃”问题。

demo:

<html>
<head>

<script src="dist/skulpt.min.js" type="text/javascript"></script>
<script src="dist/skulpt-stdlib.js" type="text/javascript"></script>

</head>

<body>

<script type="text/javascript">

function outf(text) {
    var mypre = document.getElementById("output");
    mypre.innerHTML = mypre.innerHTML + text;
}
function builtinRead(x) {
    if (Sk.builtinFiles === undefined || Sk.builtinFiles["files"][x] === undefined)
            throw "File not found: '" + x + "'";
    return Sk.builtinFiles["files"][x];
}
function runit() {
   var prog = document.getElementById("yourcode").value;
   var mypre = document.getElementById("output");
   mypre.innerHTML = '';
   Sk.pre = "output";
    Sk.configure({ output: outf, read: builtinRead, __future__: Sk.python3});

   (Sk.TurtleGraphics || (Sk.TurtleGraphics = {})).target = 'mycanvas';
   var myPromise = Sk.misceval.asyncToPromise(function() {
       return Sk.importMainWithBody("<stdin>", false, prog, true);
   });

   myPromise.then(function(mod) {
       console.log('success');
   },
       function(err) {
       console.log(err.toString());
   });
}
</script>

<h3>Try This</h3>
<form>
<textarea id="yourcode" cols="80" rows="10">
import turtle
print('hello')
t = turtle.Turtle()
t.color('red')
t.forward(75)
</textarea><br />
<button type="button" onclick="runit()">Run</button>
</form>
<pre id="output" ></pre>
<div id="mycanvas"></div>

</body>

</html>

  

但是,有的问题,不能识别eval函数,不知道为什么?
