index.js代碼
Page({ data:{ // tab 切換 tabArr: { curHdIndex: 0, curBdIndex: 0 }, }, //tab切換 tab: function (e) { //var dataId = e.currentTarget.dataset.id; var dataId = e.currentTarget.id; var obj = {}; obj.curHdIndex = dataId; obj.curBdIndex = dataId; this.setData({ tabArr: obj }) //console.log(e); }, })
參數傳遞
在view上綁定id和data-id 都可以傳遞兩個參數,然后用bindtap綁定事件,就可以傳遞兩個參數值
獲取參數
用tab:function(e){}可以獲取參數,可以console.log(e) 打印出來。用
var dataId = e.currentTarget.dataset.id; var dataId = e.currentTarget.id;
就可以獲取到兩個不同的id參數
剩下的就可以為所欲為了
