在IE8上JS实现combobox支持拼音检索功能

(编辑：jimmy 日期: 2024/11/21 浏览：3 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="/UploadFiles/2021-04-02/autoComplete.js">


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。

高通与谷歌联手！首款骁龙PC优化Chrome浏览器发布
高通和谷歌日前宣布，推出首次面向搭载骁龙的Windows PC的优化版Chrome浏览器。
在对骁龙X Elite参考设计的初步测试中，全新的Chrome浏览器在Speedometer 2.1基准测试中实现了显著的性能提升。
预计在2024年年中之前，搭载骁龙X Elite计算平台的PC将面世。该浏览器的提前问世，有助于骁龙PC问世就获得满血表现。
谷歌高级副总裁Hiroshi Lockheimer表示，此次与高通的合作将有助于确保Chrome用户在当前ARM兼容的PC上获得最佳的浏览体验。
