How do I activate existing HTML button, say running the onClick function in specific button?
When using document.getElementById("Button ID").onclick I get the function with the parameters, like the following example. but how do I run the function?
Example, the document.getElementById("Button ID") result is:
ƒ onclick(event) {calculate('ABC',1,8)}
In this example, how do I run calculate('ABC',1,8) function from javascript?
You can call the click method on the button element.
document.getElementById("Button ID").click()
(), i.e: fn().You need to call it as follow:
document.getElementById("Button ID").click();
I recommend you to read about addEventListener and Event click.
const calculate = (p1, p2, p3) => {
return p2 + p3
}
document.getElementById("Button ID").onclick = () => {
const res = calculate('ABC',1,8)
alert (res)
}
