回复讨论(解决方案)

这是有个插件的，我前段时间还帮别人搞了个，只是里面有些修改的，是别人做的。

例子：http://s.dingso.com/ds.jsp?q1=设计玩具&q2=&q3_1=&q3_2=&q3_3=&q4=&Sortt=2&Periodd=3&startat=0

google　一个这个：autocomplete　就知道了

就是发ajax返回结果集后操作页面显示

// script by blueDestiny
// email : blueDestiny [at] 126 . com

// Object: jsAuto
// browser: ie, mf.
// example:

// step1 :
// create autocomplete container, return object and bind event to the object, and
///create a new jsAuto instance:
//
// var autocomplete = new jsAuto("autocomplete","divautocomplete")
// handle event:
// autocomplete.handleEvent(value, returnObjectID)
//

// step2 :
// add autocompete item:
// autocomplete.item(string)
// string must be a string var, you can split the string by ","
// autocomplete.item("blueDestiny,never-online,csdn,blueidea")
