action-sheet

Usage

Module

Dom

Usage

import {Dom} from '@mand-mobile/platform-runtime/lib/module'

const $MDDom = Dom.bind(this) // scoped selector like refs
$MDDom().querySelector('xxxx').getScrollOffset()

API

documentElement

documentElement(): nodeRef

uniapp返回的是可视区域实例 查看详情

$MDDom().documentElement()

querySelector

querySelector(elNmae: string): nodeRef

export default {
  async mounted () {
    const testNodeRef = this.$MDDom().querySelector('.test')
    const rect: DOMRect = await testNodeRef.getBoundingClientRect()
  }
}

querySelectorAll

querySelectorAll(elNmae: string): nodeRef

uniapp中返回的不是真实数组，所以不能直接用length等属性，需调用getNode方法

export default {
  async mounted () {
    const firsttTestNodeRef = this.$MDDom().querySelector('.test')[0]
    const rect: DOMRect = await firsttTestNodeRef.getBoundingClientRect()
  }
}

getNode

getNode(): Promise<any[]>

web中不做处理直接返回dom节点，uniapp支持Canvas节点的获取 查看详情

const nodeRefs = $MDDom().querySelectorAll('.test')
const nodes = await nodeRefs.getNode()
 
 
console.log(nodes) // [node, node, ...]
 
const nodeRef = $MDDom().querySelector('.test')
const node = await nodeRefs.getNode()
 
console.log(node) 

getAttribute

getAttribute(prop: string): Promise<any>

uniapp中只能查询id或者nodesRef.fields方法中properties中可查询属性

export default {
  async mounted () {
    await $MDDom().querySelector('.test').getAttribute('id')
  }
}

getBoundingClientRect

getBoundingClientRect(): Promise<DOMRect>

export default {
  async mounted () {
    await $MDDom().querySelector('.test').getBoundingClientRect()
  }
}

getScrollOffset

getScrollOffset(): Promise<{scrollLeft: number, scrollTop: number }>

export default {
  async mounted () {
    await $MDDom().querySelector('.test').getScrollOffset()
  }
}

getComputedStyle

getComputedStyle(propList: Array<string>): Promise<object>

export default {
  async mounted () {
    await $MDDom().querySelector('.test').getComputedStyle(['position'])
  }
}

Device

Usage

import {Device} from '@mand-mobile/platform-runtime/lib/module'

const device = Device()
device.vibrate()

or

export default {
  mounted () {
    $MDDevice().vibrate()
  }
}

API

vibrate

短时震动，仅在小程序真机有效，web和小程序调试工具无效
