微信小程序原生写法传递参数

 微信小程序原生写法传递参数

 

 

data-xxx   自定义参数名  ，接收参数：方法（变量名） 

	checkVip:function(event)  {
		let that = this
		console.log(event,'event')
		console.log(event.currentTarget.dataset.idx,'index')
		let index = Number(event.currentTarget.dataset.idx)
		// // this.isChek = index
		let checkMoney = that.data.vipList[index].price
		console.log(checkMoney,'this.checkMoney')
		that.setData({
			isChek: event.currentTarget.dataset.idx,
			checkMoney:that.data.vipList[index].price
		})
		// this.pay_Money = price
	},

如果需要传递多个，可以写多个data-[参数]的方式进行传递

多个参数写法 data-a ，data-b, 接收参数 ：方法（变量名）  

	checkVip:function(event)  {
		let that = this
		console.log(event.currentTarget.dataset.a,'index1')
		console.log(event.currentTarget.dataset.b,'index2')
	},

 建议采用全小写命名,简短短拼~
