@wines/select

@wines/select

Select 下拉框

用于弹出一个下拉菜单给用户选择操作。

使用指南

在 page.json 中引入组件

{
  "navigationBarTitleText": "Select",
  "usingComponents": {
    "wux-cell": "@wines/cell",
    "wux-cell-group": "@wines/cell-group",
    "wux-select": "@wines/select"
  }
}

示例

该组件主要依靠 JavaScript 主动调用，所以一般只需在 wxml 中添加一个组件，并设置 id 为 #wux-select 或其他，之后在 page.js 中调用 $wuxSelect(context, id) 获取匹配到的第一个组件实例对象。

<wux-select id="wux-select1" />
<wux-select id="wux-select2" />
<wux-select id="wux-select3" />
<view class="page">
	<view class="page__hd">
		<view class="page__title">Select</view>
		<view class="page__desc">下拉框</view>
	</view>
	<view class="page__bd">
		<wux-cell-group>
			<wux-cell
			 title="Single"
			 is-link
			 extra="{{ displayValue1 }}"
			 bind:click="onClick1"
			/>
			<wux-cell
			 title="Multiple"
			 is-link
			 extra="{{ displayValue2 }}"
			 bind:click="onClick2"
			/>
			<wux-cell
			 title="Multiple & max = 3"
			 is-link
			 extra="{{ displayValue3 }}"
			 bind:click="onClick3"
			/>
		</wux-cell-group>
	</view>
</view>
