<script>
window.onload=function(){
var oBtn=document.getElementById('btn1');
var oTxt=document.getElementById('txt1');
oBtn.onclick=function(){
var oNewWin=window.open('about:blank','_blank');
oNewWin.document.write(oTxt.value);
};
};
</script>

<body>
<textarea id="txt1" rows="10" cols="40">
</textarea><br/>
<input type="button" id="btn1" value="运行"/>
<!--<input type="button" value="打开窗口" onclick="window.open('../优酷整站实例-css/源码及素材/youku/youguili.html')"/>
<input type="button" value="write" onclick="document.write('abc')"/>
document.write结合事件来用，会先把页面上的内容清空了，再把write里面的内容写到页面-->
</body>
</html>
