I can't understand, why addEventListener("click") starts after page loading, not waiting for "click". What is worse - it does not work on click again. Below you can find script:
const seven = document.getElementById("seven");
seven.addEventListener("click", typeNumber(7));
function typeNumber(a){
calculations.innerText = calculations.innerText + a;
}
No matter what function I add to event listener (console log, alert etc) it always starts when the page starts. Are you able to help?
I tried to choose different types of function invocations
Call typeNumber
inside an anonymous function, rather than calling it immediately and passing the return value to addEventListener
(when it expects a function as the second argument).
const seven = document.getElementById("seven");
seven.addEventListener("click", () => typeNumber(7));
function typeNumber(a){
document.getElementById("calculations").innerText = calculations.innerText + a;
}
<button id="seven">7</button>
<p id="calculations"></p>
