方案一
JS
clickMe.addEventListener('click', function(e){
popover.style.display = 'block'
})
wrapper.addEventListener('click', function(e){
e.stopPropagation()
})
document.addEventListener('click', function(){
popover.style.display = 'none'
})
方案二
JS
$(clickMe).on('click', function() {
$(popover).show()
console.log('show')
setTimeout(function() {
console.log('添加 one click')
$(document).one('click', function() {
console.log('我覺(jué)得這里不會(huì)執(zhí)行')
console.log('hide')
$(popover).hide()
})
}, 0)
})
