做一个自己的网页编译器

做一个自己可以编译网页的编译器，我总结了前辈们的代码，自己修改了下

<script>...
<!--
vari=0;
varie=(document.all)?1:0;
varns=(document.layers)?1:0;
//预览
functionpreview()
...{
if(document.pad.text.value.length>0)
...{
pr=window.open("","Preview","scrollbars=1,menubar=1,status=1,width=480height=320,left=10,top=10");
pr.document.write(document.pad.text.value);
}
elsealert('没有代码可预览!')
}
//保存
functionsavetxt()...{
if(document.pad.text.value.length>0)
...{
varnewwin=window.open('about:blank','','top=10000');
newwin.document.write(document.pad.text.value);
newwin.document.execCommand('saveas','','hx66.html')
newwin.window.close();
}
elsealert('没有代码可保存!')
}
//-->
</script>
