Javascript - event listener toggle button
- by user2546157
I'm trying to create a button which can toggle "double click" to "single click" and in the opposite. For some reason, once it toggles to single click and it cannot toggle back. Can anyone please help!
function init() {
normal_listeners();
}
function addListener(){
var image1 = document.getElementById('image_1');
var image2 = document.getElementById('image_2');
var image3 = document.getElementById('image_3');
if(document.getElementById('listener_1').value == "Listener"){
document.getElementById('listener_1').style.backgroundColor = "red";
alert("Normal");
image1.addEventListener("dblclick", function(){userChoice(1);}, false);
image2.addEventListener("dblclick", function(){userChoice(2);}, false);
image3.addEventListener("dblclick", function(){userChoice(3);}, false);
document.getElementById('listener_1').value = "Normal";
}
else if(document.getElementById('listener_1').value == "Normal") {
document.getElementById('listener_1').style.backgroundColor = "green";
alert("Listener");
image1.addEventListener("click", function(){userChoice(1);}, false);
image2.addEventListener("click", function(){userChoice(2);}, false);
image3.addEventListener("click", function(){userChoice(3);}, false);
document.getElementById('listener_1').value = "Listener";
}
}
function normal_listeners(){
var image1 = document.getElementById('image_1');
var image2 = document.getElementById('image_2');
var image3 = document.getElementById('image_3');
var listener1 = document.getElementById('listener_1');
listener1.addEventListener("click", addListener, false);
image1.addEventListener("dblclick", function(){userChoice(1);}, false);
image2.addEventListener("dblclick", function(){userChoice(2);}, false);
image3.addEventListener("dblclick", function(){userChoice(3);}, false);
}
window.onload = init;
