uniapp 扩展picker-view实现条件查询

发布于:2024-11-28 ⋅ 阅读:(16) ⋅ 点赞:(0)

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
在这里插入图片描述
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
