There was an image that triggered the add_cart() JavaScript function when clicked using onclick()
<img src="images/add.png" onclick="add_cart()">
The goal is to limit the user to clicking the image only once. Upon the first click, the add_cart function should be executed. Any subsequent clicks should not trigger any event.
<img src="images/plus.png" onclick="addToCart(); this.onclick=null;">
If you are working with jQuery on the client side, you have the option to utilize the jQuery one method
$(".myDiv").one("click", function(){
alert("this will occur only once");
});
Cheers
Utilizing
<img src="images/add.png" onclick="this.onclick = function(){};add_cart();">
document.addEventListener('DOMContentLoaded', function() {
document.getElementById('myImage').addEventListener('click', handleImageClick);
});
var handleImageClick = function(e) {
var element;
if (!e) var e = window.event;
if (e.target) element = e.target;
else if (e.srcElement) element = e.srcElement;
if (element.nodeType == 3) // fix for Safari bug
element = element.parentNode;
if(element) {
element.addEventListener('click', function(){});
// add your code here
}
