因为选项值过多，需要动态查询，现有组件无法实现，将picker-view扩展了一下，支持条件查询，接口调用。
实现效果
注意：直接使用，样式可能不准，根据自己的实际情况进行样式调整
参数说明
params: 数据接口参数，必填
{
url: 接口地址,
method: 请求方式，默认'get',
data: 接口参数,
search: 额外的参数
},
options: 显示数据集
{
value: 实际值字段,
name: 显示值字段
},
placeholder: 查询条件提示文字 默认"请输入查询条件"
maxSize: 显示选项数量最大值，默认 100
事件说明
@handlerChange： 确认时间，返回完整选项行数据
@close：关闭组件
