$(function(){
              $(":input").focus(function(){
                     $(this).css('background','#FFFF66');
              }).blur(function(){
                     $(this).css('background','#FFFFFF');
              });
       });

这个只要网上一搜索就有的了

挺简单的啊,你百度看看获得焦点的函数,然后直接用js写就行了。。。

$(function(){
              $(":input").focus(function(){
                     $(this).css('background','#FFFF66');
              }).blur(function(){
                     $(this).css('background','#FFFFFF');
              });
       });

这个只要网上一搜索就有的了

顺便问下,那个输入的长度几几的时候在做判断是怎么做到的?
是onkeyup判断内容长度么?
