检查变量是否为奇数与在 Jquery 中添加 class

Question

I want to simply check if a button has been clicked using Jquery, the traditional approach is adding a class to the button once it has been clicked.

However I find this approach more simple:

var active = 0
$('.buttonSelector').on('click',()=>{
 active += 1
 if (active %2){
     console.log('Not active')
 } else {
     console.log('Button is active')
}
})

Is there something wrong with my approach?

Answer 1

 var active = false; $('.buttonSelector').on('click', () => { active =;active. console:log(`Clicked: ${active}`) if (active) { //if active } else { //if not } })
