jQueryUI实现email输入提示实例_jquery

var emails=["163.com","yahoo.com","yahoo.cn","126.com","sina.com"];
$( function () {
//为输入框绑定事件
$( "#email" ).keyup( function(){
emailiInp();
});
});
function emailiInp(){
var arrs= new Array()
inpVal=$( "#email" ).val();
//根据输入的值，动态的创建下拉列表
$.each(emails, function (index,info){
if (inpVal.indexOf("@" )==-1)
{
//没有输入@
arrs[index]=inpVal+ "@" +info;
} else {
//输入@
arrs[index]=inpVal.substring(0,inpVal.indexOf( "@" ))+"@" +info;
}
})
$( "#email" ).autocomplete({
//绑定下拉列表内容
source: arrs
});
}

最后再来个文本框：
