基于jquery的可查询多级select控件（可记录历史选择）
一、功能和使用
公司有功能需求，还要一条代码引入的控件，网上找完全符合的控件比较难，寻找所花的时间还不如自己写一个，所以找个空闲时间自己写了一个
控件功能：1、可手动输入查询，也可点击下拉框查询，
2、输入时实时定位到下拉框，enter补全
3、可多级查询（目前是写到二级）
4、localStorage存储历史记录
控件使用：引入相应的js和css文件，需要控件的html中加一个div
<div id="multiple_select" class="multiple-select-container"></div>
js里引入控件
$("#multiple_select").multiSelect({
type:'2',//可选择几级数据
data:data.list,
noneSelectedText: '请选择',
field:['provence','city','name'] //option字段，【一级字段，二级字段，显示字段】
});
