用Javascript转换源代码
例子:<html><head><title>无标题文档</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"></head><body bgcolor="#FFFFFF" text="#000000"></body></html>
<script>txt="";txt2="";txt3="";num=0function hh(){document.all.n1.value=Math.floor(num/txt.length*100)+"%"txt3=txt.charAt(num)if(txt3 == " "){txt3=" "};if(txt3 == "&"){txt3="&"};if(txt3 == "\""){txt3="""};if(txt3 == "<"){txt3="<"};if(txt3 == ">"){txt3=">"}txt2=txt2+txt3num++;if(num != txt.length){setTimeout("hh()",1)};else{document.all.n1.value=txt2}}</script> 源代码如下：
<textarea style="width:500;height:200" name="n1">
例子:
&lt;html&gt;
&lt;head&gt;
&lt;title&gt;无标题文档&lt;/title&gt;
&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" 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>
