运行一下这个，看看select的属性。<html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title></title> </head> <body> <select id=test> </select> <SCRIPT LANGUAGE="JavaScript"> <!-- for (a in test) { if (a == "title") document.write("<FONT SIZE='6' COLOR='red'>") document.write(a+"\t"); if (a == "title") document.write("</FONT>") } //--> </SCRIPT> </body> </html>
好可爱的emu，顺便教你一招 a.fontcolor("red").fontsize(6)ps.有属性不一定等于有效，所以DHTML中不敢写<select id=test> </select> <SCRIPT LANGUAGE="JavaScript"> <!-- for (a in test){ if (a == "title") a=a.fontcolor("red").fontsize(6) document.write(a+"\t"); } //--> </SCRIPT>
好玩儿，书里好像没有讲的。这个title真的出不来了吗？

哈哈，看到它是怎么做的啦，原来创建了font对象来的var a = "adfsdf"; a=a.fontsize(6).fontcolor("red") alert(a)
it works when SELECT is disabled, :-), try<select name="NAME" size="1" disabled title="This text should appear in a tooltip popup."> <option>Option1 </option> <option>Option2 </option> <option>Option3 </option> </select>see PRB: Internet Explorer Does Not Display Title Attribute Using the Select Tag (Q221608) http://support.microsoft.com/default.aspx?scid=kb;EN-US;q221608
看到了Microsoft has confirmed this to be a bug in the Microsoft products 唉，真的是一个bug来的
