微信小程序 action-sheet 反馈上拉菜单简单实例

看下实现效果图：

js

var items = ['item1', 'item2', 'item3', 'item4'] 
var pageobject = { 
 data: { 
  actionsheethidden: true, 
  actionsheetitems: items 
 }, 
 actionsheettap: function (e) { 
  this.setdata({ 
   actionsheethidden: !this.data.actionsheethidden 
  }) 
 }, 
 actionsheetchange: function (e) { 
  this.setdata({ 
   actionsheethidden: !this.data.actionsheethidden 
  }) 
 } 
} 
 
for (var i = 0; i < items.length; ++i) { 
 (function (itemname) { 
  pageobject['bind' + itemname] = function (e) { 
   console.log('click' + itemname, e) 
  } 
 })(items[i]) 
} 
 
page(pageobject) 

wxml

<button type="default" bindtap="actionsheettap">弹出action sheet</button> 
<action-sheet hidden="{{actionsheethidden}}" bindchange="actionsheetchange"> 
  <block wx:for-items="{{actionsheetitems}}"> 
    <action-sheet-item class="item" bindtap="bind{{item}}">{{item}}</action-sheet-item> 
  </block> 
  <action-sheet-cancel class="cancel">取消</action-sheet-cancel> 
</action-sheet>
