/*js部分，myPicker是设备号input的ID*/
$('#myPicker').change(function () {
/*选择设备号后,根据当前设备号设置不同的摄像头选项,具体判断逻辑根据具体的项目而定*/
var val = $("#myPicker").val();
if (val === "*******352") {
$("#box").empty();
$("#box").html("<input type='text' id='camera' value='前置摄像头'/>");
$("#camera").picker({
title: "请选择摄像头",
cols: [
{
textAlign: 'center',
values: ['前置摄像头']
}

3.分析city-picker.js源码，增加参数：list-数据源，reload-是否重新加载，initVal-初始化的值，initCode-初始化的value。
- 增加参数
defaults = $.fn.cityPicker.prototype.defaults = {
showDistrict: true, //是否显示区
list:[], //数据源
reload:false, //是否重新加载
initVal:"", //初始化的值
initCode:"" //初始化的value
};
2.增加方法给数据源赋值
//将raw的值干掉
var raw = [];
//增加方法给raw赋值
var setList = function(data){
raw = data;
}
//city-picker调研的时候给raw赋值
$.fn.cityPicker = function(params) {
params = $.extend({}, defaults, params);
return this.each(function() {
var self = this;
//根据参数给raw赋值
if(params.list != null && params.list.length>0){
setList(params.list);
}
//后续代码就不截了
.
.
.
3.发现jquery-weui的city-picker是在JQuery weui picker的基础上开发的，修改调用方式
if(params.reload){
$("#city-picker").empty();
$("#city-picker").html("<input type='text' placeholder='请选择地区' class='city-picker'>");
if(params.initVal != null && params.initVal != ""){
$(".city-picker").val(params.initVal);
$(".city-picker").attr("data-values",params.initCode);
}
$(".city-picker").picker(p);
}else{
$(this).picker(p);
}
