在IE8上JS实现combobox支持拼音检索功能
时间：2022-04-20 08:59:43|栏目：JavaScript代码|点击： 次
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：
test
|--js
|--index.html
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。
