Page({ data:{ // tab 切换 tabArr: { curHdIndex: 0, curBdIndex: 0 }, }, //tab切换 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); }, })
参数传递code
在view上绑定id和data-id 均可以传递两个参数,而后用bindtap绑定事件,就能够传递两个参数值xml
获取参数blog
用tab:function(e){}能够获取参数,能够console.log(e) 打印出来。用事件
var dataId = e.currentTarget.dataset.id; var dataId = e.currentTarget.id;
就能够获取到两个不一样的id参数get
剩下的就能够随心所欲了it
