Im trying to keep a clicked button active as long as it is still clicked. I have tried a lot of things but this doesnt seem to work. The colored effect doesnt last more than 1 second and it’s not depending from the click.
Here is my code :
// Add active class to the current button
var header = document.getElementById("myDIV");
var btns = header.getElementsByClassName("btn");
for (var i = 0; i < btns.length; i++) {
btns[i].addEventListener("click", function() {
var current = document.getElementsByClassName("active");
if (current.length > 0) {
current[0].className = current[0].className.replace(" active", "");
}
this.className += " active";
});
}.active {
background-color: #545454;
}<div id="myDIV">
<table class="secondTable">
<tr>
<th><button class="btn" style="margin-left: -6px;">button1</button></th>
<th></th>
<th></th>
</tr>
<tr>
<th><button class="btn" style="margin-left: -6px;">button2</button></th>
<th></th>
<th></th>
</tr>
</table>
</div>I have tried every possible thing but im not able to figure out what the problem is. The styling should just involve color changing.
NB: my css looks like this .active { background-color: #545454; }
Thanks a lot!
