Stack Overflow Asked on November 15, 2021
Like the title says, I’m trying to make a function in Javascript that counts how many divs are clicked A N D tell me which ones were clicked For example:
<div>
<div onclick="somefunction">1</div>
<div onclick="somefunction">2</div>
<div onclick="somefunction">3</div>
<div onclick="somefunction">4</div>
</div>
Let’s say div 1 and 2 are clicked, how do I make a javascript function that will tell me which divs were clicked (in our case 1 and 2 were) and total number of divs that were clicked?
To keep track of the amount of clicks, I would declare a public variable that keeps track of the click count and have the function increment it each time it is called.
To check which div is clicked, I would pass the number of the div as a parameter.
HTML:
<div onclick="someFunction(1)"> 1 </div>
<br>
<div onclick="someFunction(2)"> 2 </div>
<br>
<div onclick="someFunction(3)"> 3 </div>
<br>
<div onclick="someFunction(4)"> 4 </div>
Javascript:
var clickCount = 0;
function someFunction(divNum)
{
++clickCount;
console.log("Clicks: " + clickCount);
switch (divNum)
{
case 1:
console.log("Clicked: " + 1);
break;
case 2:
console.log("Clicked: " + 2);
break;
case 3:
console.log("Clicked: " + 3);
break;
case 4:
console.log("Clicked: " + 4);
break;
}
}

var divsClicked="divs clicked = ";
var count = 0;
display=document.getElementById('display');
function somefunction(num){
divsClicked = divsClicked + num + ",";
count++;
display.innerHTML=divsClicked + "count =" + count;
}<div>
<div onclick="somefunction(1)">1</div>
<div onclick="somefunction(2)">2</div>
<div onclick="somefunction(3)">3</div>
<div onclick="somefunction(4)">4</div>
</div>
<div id='display'><div>Answered by DCR on November 15, 2021
