微信小程序 wxml文件中常用的幾個方法

1. 列表給值

				<view class='item' wx:for="{{lesson}}" wx:key="ID" wx:for-item="item">

2. 點擊事件 並傳值

<label id="btnCollect_40"  class='deletecolor' bindtap="collectionClick" data-id='{{item.ID}}' wx:else>收藏</label>

取值

collectionClick:function(event){

    var id = event.currentTarget.dataset.id;


}

3.跳轉頁面帶值

 ShowResourceList:function(event){
    var id = event.currentTarget.dataset.id;
    wx.navigateTo({
      url: '../detail/detail?id='+id
    })

  },

取值

 

 onLoad: function (options) {
   //獲取參數
    var typeid = options.id;
    

  },

2）傳遞多個參數

 wx.navigateTo({
      url: '../tingxie/tingxie?id=' + that.data.audioID + "&url=" + that.data.audiourl + "&classlist=" + sa + "&random=" +random_s1 + "&readnumber=" + that.data.readnumber
    })

取值

onLoad: function (options) {
    var typeid = options.id;
    var url = options.url;
    var classlist = JSON.parse(options.classlist);
    var random_s1 = options.random;
    ......

}
