&lt;meta http-equiv=&quot;Content-Type&quot; content=&quot;text/html; charset=gb2312&quot;&gt;

&lt;/head&gt;

&lt;body bgcolor=&quot;#FFFFFF&quot; text=&quot;#000000&quot;&gt;

&lt;/body&gt;

&lt;/html&gt;

</textarea><br>

<input type="button" onclick="txt=document.all.n1.value;hh()" value="转换"> <script>

txt="";txt2="";txt3="";num=0

function hh(){

document.all.n1.value=Math.floor(num/txt.length*100)+"%"

txt3=txt.charAt(num)

if(txt3 == " "){txt3="&nbsp;"};if(txt3 == "&"){txt3="&amp;"};if(txt3 == "\""){txt3="&quot;"};if(txt3 == "<"){txt3="&lt;"};if(txt3 == ">"){txt3="&gt;"}

txt2=txt2+txt3

num++;if(num != txt.length){setTimeout("hh()",1)};else{document.all.n1.value=txt2}

}

</script>
