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>...
<!--
var i=0;
var ie=(document.all)?1:0;
var ns=(document.layers)?1:0;
// 预览
function preview()
...{
if(document.pad.text.value.length>0)
...{
pr=window.open("","Preview","scrollbars=1,menubar=1,status=1,width=480 height=320,left=10,top=10");
pr.document.write(document.pad.text.value);
}
else alert('没有代码可预览!')
}
// 保存
function savetxt() ...{
if(document.pad.text.value.length>0)
...{
var newwin=window.open('about:blank','','top=10000');
newwin.document.write(document.pad.text.value);
newwin.document.execCommand('saveas','','hx66.html')
newwin.window.close();
}
else alert('没有代码可保存!')
}
