如题，
如数值1变成文本1，
另外文本变数值又是什么函数？
var num = 1;
var str = num + "";
var num = 1;
var str = num.toString();
数值变成文本 x = "" + x;
文本变数值 x = 1 * x;
---------------------------------
数值变成文本 var x =String(123)
文本变数值 x = parseInt(x); 或 x = parseFloat(x);
HTML code:
<script type="text/javascript" src="http://localhost/mycenter/js/jquery.min.js"></script>
<script>
$("#menu2 li").each(function(){
var reid=$(this).attr("rel");
$(this).hover(function(){
$(this).append(
"<ul class=\""+reid+"\">"+
"{dede:channel type=son typeid="+reid+" row=10}"+
"<li><a href='[field:typelink/]'>[field:typename/]</a></li>"+
"{/dede:channel}"+
"</ul>"
)
});
});
