How to show the total increment of an app counter-CodePudding

Guys I wanna make an app which can count people, I have it according to the course but I'd like to add the total at the end not the previous entries.

enter image description here

let saveEl = document.getElementById("save-el")
let countEl = document.getElementById("count-el")

let count = 0

function counter() {

    count  = 1
    countEl.textContent = count

}

function save()   {

    //let countStr = count   "-" caso eu não queira que volte do zero

    let countStr = count   " - "

    saveEl.textContent  = countStr 

    countEl.textContent = 0

    count = 0

}



console.log(count)

CodePudding user response：

Instructions were not clear but I guess you want to "sum up the counts" instead of displaying them separately.

Here's a codepen achieving that, hopefully that works for you ;)

let saveEl = document.getElementById("save-el")
let countEl = document.getElementById("count-el")

let count = 0

function counter() {
    count  = 1
    countEl.textContent = count
}

function save() {
    let prevCount = saveEl.textContent ? parseInt(saveEl.textContent) : 0
    saveEl.textContent = count   prevCount

    countEl.textContent = 0
    count = 0
}
