最近在ie8碰到一个js问题，需要实现(ie8)使用拼音或者拼音首字母来检索select中的内容，原来的combobox只能支持汉字输入检索，现在需要进行改进，现在我将一步一步的实现方法记录下来，功能简单，也可能有bug和不足，供学习参考。(本文只是提供思路学习和备份，实际情况需要在ie8或者ie兼容模式上使用，所以没有考虑到别的浏览器)
目录结构：

在index页面中添加
index.html
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title></title> <script type="text/javascript" src="js/autoComplete.js" ></script> <script type="text/javascript"> </script> </head> <body> <input type="text" id="txtDisplay" /> <select id="city"> <option value="1">北京</option> <option value="2">上海</option> <option value="3">广州</option> <option value="4">深圳</option> <option value="5">重庆</option> <option value="6">天津</option> <option value="7">沈阳</option> <option value="8">南京</option> <option value="9">武汉</option> <option value="10">长春</option> <option value="11">成都</option> <option value="12">大连</option> <option value="13">杭州</option> <option value="14">青岛</option> <option value="15">a济南</option> <option value="16">厦门</option> <option value="17">福州</option> <option value="18">西安</option> <option value="19">长沙</option> <option value="20">哈尔滨</option> </select> </body> </html>
效果：开始将select 的下拉列表框隐藏，当点击input文本框的时候显示到input框的下面，选择完成后再将select隐藏。
js实现：
如果一个页面有多个地方需要实现这样的功能，这个时候就要使用面向对象的思维，尽可能代码重用，我们需要自定义一个ap这样的集合。
autoComplete.js
function Map() { /** 存放键的数组(遍历用到) */ this.keys = new Array(); /** 存放数据 */ this.data = new Object(); /** * 放入一个键值对 * @param {String} key * @param {Object} value */ this.put = function(key, value) { if(this.data[key] == null){ this.keys.push(key); } this.data[key] = value; }; /** * 获取某键对应的值 * @param {String} key * @return {Object} value */ this.get = function(key) { return this.data[key]; }; /** * 删除一个键值对 * @param {String} key */ this.remove = function(key) { this.keys.remove(key); this.data[key] = null; }; /** * 遍历Map,执行处理函数 * * @param {Function} 回调函数 function(key,value,index){..} */ this.each = function(fn){ if(typeof fn != 'function'){ return; } var len = this.keys.length; for(var i=0;i<len;i++){ var k = this.keys[i]; fn(k,this.data[k],i); } }; /** * 获取键值数组(类似Java的entrySet()) * @return 键值对象{key,value}的数组 */ this.entrys = function() { var len = this.keys.length; var entrys = new Array(len); for (var i = 0; i < len; i++) { entrys[i] = { key : this.keys[i], value : this.data[i] }; } return entrys; }; /** * 判断Map是否为空 */ this.isEmpty = function() { return this.keys.length == 0; }; /** * 获取键值对数量 */ this.size = function(){ return this.keys.length; }; /** * 重写toString */ this.toString = function(){ var s = "{"; for(var i=0;i<this.keys.length;i++,s+=','){ var k = this.keys[i]; s += k+"="+this.data[k]; } s+="}"; return s; }; } Array.prototype.remove = function(s) { for (var i = 0; i < this.length; i++) { if (s == this[i]) this.splice(i, 1); } }现在我们要写一个程序加载入口文件，用来将input和select的对象传入，然后进行事件绑定等等一系列的操作。
