script tag create with innerHTML of a div doesn't work
<p>here goes the js code </p>

<pre><code>var wrap = document.createElement("div");
wrap.innerHTML = '&lt;script type="text/javascript" src="'+scriptUrl+'"&gt;&lt;/script&gt;';
var wrapscript = wrap.childNodes[0];
document.body.appendChild(wrapscript)
</code></pre>

<p>the body did insert the script element,but the js resource was't load,even no http request...</p>

<p>who can tell me why~~  </p>

<p>the problem goes with Zeptojs's $ method</p>

<pre><code>$('&lt;script type="text/javascript" src="'+scriptUrl+'"&gt;&lt;/script&gt;').appendTo($("bdoy"))
</code></pre>

<p>it works like the code above,and cause the bug</p>
