Page event

0.6.1

Weex provides you with simple management of page status, such as viewappear and viewdisappear，

The viewappear event will be triggered when page is about to show or before any animations are configured for showing. For example, when calling push method in navigator module, this event will be trigged in new page.

The viewdisappear event will be triggeded when page is about to dismiss.

Different from appear and disappear of component, these two events focus on the status of whole page, so they must be bound to the root component.

e.g.

<template>
  <div onviewappear="viewappear" onviewdisappear="viewdisappear">
  		......
  </div>
</template>

<script>
  module.exports = {
    methods: {
      viewappear: function (e) {
        // handle view appear event
      },
      viewdisappear: function (e) {
        // handle view disappear event
    }
  }
</script>

In addititon，these events also can be bound to body component which is not root actually such as wxc-navpage.

event object

  • type: viewappear or viewdisappear
  • target: The object where event is triggered
  • timestamp: Timestamp when event is triggered.
