1. Eine js-Datei ist erforderlich: jquery.mailAutoComplete-3.1.js
(function($){
$.fn.mailAutoComplete = function(options){
var defaults = {
boxClass: "mailListBox", //外部box样式
listClass: "mailListDefault", //默认的列表样式
focusClass: "mailListFocus", //列表选样式中
markCalss: "mailListHlignt", //高亮样式
zIndex: 1,
autoClass: true, //是否使用插件自带class样式
mailArr: ["qq.com","gmail.com","126.com","163.com","hotmail.com","yahoo.com","yahoo.com.cn","live.com","sohu.com","sina.com"], //邮件数组
textHint: false, //文字提示的自动显示与隐藏
hintText: "",
focusColor: "#333",
blurColor: "#999"
};
var settings = $.extend({}, defaults, options || {});
//页面装载CSS样式
if(settings.autoClass && $("#mailListAppendCss").size() === 0){
$('').appendTo($("head"));
}
var cb = settings.boxClass, cl = settings.listClass, cf = settings.focusClass, cm = settings.markCalss; //插件的class变量
var z = settings.zIndex, newArr = mailArr = settings.mailArr, hint = settings.textHint, text = settings.hintText, fc = settings.focusColor, bc = settings.blurColor;
//创建邮件内部列表内容
$.createHtml = function(str, arr, cur){
var mailHtml = "";
if($.isArray(arr)){
$.each(arr, function(i, n){
if(i === cur){

'+str+'@'+arr[i]+'
';

};
//一些全局变量
var index = -1, s;
$(this).each(function(){
var that = $(this), i = $(".justForJs").size();
if(i > 0){ //只绑定一个文本框
return;
}
var w = that.outerWidth(), h = that.outerHeight(); //获取当前对象(即文本框)的宽高
//样式的初始化
that.wrap('

.before('

var x = $("#mailListBox_" i), liveValue; //Listbox-Objekt
that.focus(function(){

/ /Wenn die Taste oben oder unten ist
if(e.keyCode === 38){

}
//Mouse over list item event
/ /Mouse over
$(".mailHover").live("mouseover", function(){

liveValue = $("#mailList_" index).text();
x.children("." cf).removeClass(cf).addClass(cl); this).addClass(cf).removeClass(cl);
x.bind("mousedown", function(){
that.val( liveValue);
});
})(jQuery) ist natürlich unerlässlich, Hier ist Auslassen
