I try to create a toggle button in order to show/hide some content. For the moment, I use that :
// test.js
var toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function() {
content.style.display = (content.dataset.toggled ^= 1) ? "block" : "none";
});#content {
display: none;
}<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="style.css">
<script type="text/javascript" src="test.js"></script>
</head>
<body>
<button id="toggle">Click Me</button>
<div id="content">Hello World</div>
</body>
</html>If I use these code with codepen or JSFiddle, all works fine, but when I try it locally, ( when I click on my index.html file, open it with firefox or an other browser ) my button "Click Me" doesn't works.
When I click on it, nothing happens...
Someone to show me why ?
You could make your function to be fired on load event.
Possible example
(function() {
var loadedContent = {
init: function() {
window.addEventListener("load", function(event) {
var toggle = document.getElementById("toggle");
var content = document.getElementById("content");
toggle.addEventListener("click", function() {
content.style.display = (content.dataset.toggled ^= 1) ?
"block" :
"none";
});
});
}
};
loadedContent.init();
})();#content {
display: none;
}<button id="toggle">Click Me</button>
<div id="content">Hello World</div>
