兩者有點(diǎn)擊目標(biāo)事件的區(qū)別，代碼如下
<view bindtap='del' data-id="1">
A
<view data-id="2">B</view>
<view>C</view>
</view>
del(e){
console.log('currentTarget:',e.currentTarget.dataset.id)
console.log('target:', e.target.dataset.id)
},
點(diǎn)擊A
currentTarget: 1
target: 1
點(diǎn)擊B
currentTarget: 1
target: 2
點(diǎn)擊C
currentTarget: 1
target: undefined
由上可以看出渊抽，currentTarget是冒泡事件，所有內(nèi)部點(diǎn)擊觸發(fā)
