用wx.setStorage、wx.getStorage和wx.getStorageSync进行页面间传值

用wx.setStorage、wx.getStorage和wx.getStorageSync进行页面间传值

先是存储wx.setStorage

Page({

data: {

testnum:""//设置测试参数

},

test:function(){

var Num = this.data.testnum;

wx.setStorage({//存储到本地

  key:"testNum",

  data:Num

})

}

})
另一页要获取testnum的方法
①wx.getStorage

Page({

data: {

testnum:""//设置测试参数

},

onLoad:function(option){

var that = this,

wx.getStorage({//获取本地缓存

  key:"testNum",

  success:function(res){

    that.setData({

      testnum:res.data

    )};

  },

})

}

})
②wx.getStorageSync

Page({

data: {

testnum:""//设置测试参数

},

onLoad:function(option){

var num = wx.getStorageSync('testNum');//wx.getStorageSync(key)，获取本地缓存

this.setData({

  testnum:testnum

})；

}

})
