I am trying to add a class named pressed to an element with class named w. This will happen when user clicks on element containing class w. I then want to remove the class press after delay of 100.So this is the code I have writtten.
(In short: I am trying to add animation with js by adding(and then removing after 100ms) a CSS class pressed.)
But this is not working, it's behavior is as follows:
setTimeout(foo(this.innerText), 100); even the document.querySelector("."+this.innerText).classList.add("pressed"); isn't getting executed.document.querySelector('.w').addEventListener("click",function () {
document.querySelector("."+this.innerText).classList.add("pressed");
// setTimeout(foo(this.innerText), 100);
});
function foo(stringclass) {
document.querySelector("."+stringclass).classList.remove("pressed");
console.log(stringclass);
}
Can anyone help me with this please?

setTimeout(foo(this.innerText), 100); executes foo immediately. You need to pass the function itself.
I believe you want something closer to
document.querySelector('.w').addEventListener("click",function (e) { document.querySelector("."+e.target.innerText).classList.add("pressed"); setTimeout(function() {foo(e.target.innerText)}, 100); });
