微信小程序开发--组件(3)

一、radio

group 
class="radio-group" 
bindchange="radioChange">
  class="radio" wx:for="{{items}}">
    "{{item.value}}" checked="{{item.checked}}" color='pink'/>{{item.value}}
  

 

Page({
  data: {
    items: [
      {name: 'USA', value: '美国'},
      {name: 'CHN', value: '中国', checked: 'true'},
      {name: 'BRA', value: '巴西'},
      {name: 'JPN', value: '日本'},
      {name: 'ENG', value: '英国'},
      {name: 'TUR', value: '法国'},
    ]
  },
  radioChange: function(e) {
    console.log('radio发生change事件，携带value值为：', e.detail.value)
  }
})

二、picker

从底部弹起的滚动选择器。

 

class="section">
  class="section__title">普通选择器
  "bindPickerChange" value="{{index}}" range="{{array}}">
    class="picker">
      当前选择：{{array[index]}}
    
  

class="section">
  class="section__title">多列选择器
  "multiSelector" bindchange="bindMultiPickerChange" bindcolumnchange="bindMultiPickerColumnChange" value="{{multiIndex}}" range="{{multiArray}}">
    class="picker">
      当前选择：{{multiArray[0][multiIndex[0]]}}，{{multiArray[1][multiIndex[1]]}}，{{multiArray[2][multiIndex[2]]}}
    
  

class="section">
  class="section__title">时间选择器
  "time" value="{{time}}" start="09:01" end="21:01" bindchange="bindTimeChange">
    class="picker">
      当前选择: {{time}}
    
  


class="section">
  class="section__title">日期选择器
  "date" value="{{date}}" start="2015-09-01" end="2017-09-01" bindchange="bindDateChange">
    class="picker">
      当前选择: {{date}}
    
  

class="section">
  class="section__title">省市区选择器
  "region" bindchange="bindRegionChange" value="{{region}}" custom-item="{{customItem}}">
    class="picker">
      当前选择：{{region[0]}}，{{region[1]}}，{{region[2]}}
