I have a button and I want to remove all the classes when it is clicked. Here is what I have tried:
button.style.className = ''
document.querySelector('button').onclick = function() {
this.style.className = '';
}.myClass {
color:red;
}
.second {
color:green;
}<button class="myClass second">click me</button>Since I don't know the names of the classes as they are dynamic, I cannot use classList.remove. How can I effectively remove all classes from an element?
It is not recommended to access className from the style object, instead access it directly like
this.className
document.querySelector('button').onclick = function() {
this.className = '';
}.myClass {
color:red;
}
.second {
color:green;
}<button id="button" class="myClass second">click me</button>Learn how to use the HTML DOM method called removeAttribute():
document.querySelector('button').onclick = function() {
this.removeAttribute("class");
}.myClass {
background-color:blue;
}
.second {
box-shadow: 0px 0px 5px 5px;
}<button id="button" class="myClass second">click me</button>Try using this.classname in place of this.style.className. Your updated Javascript snippet will look like this:
document.querySelector('button').onclick = function() {
this.classname = ''; //removing the .style
}
To fix the issue, simply delete the (.style) part from the code and everything will function correctly.
button.className = '';
Alternatively, you can also utilize this.className = "";
Both methods are effective in resolving the issue.
The following code snippet does the trick for me:
document.getElementById('targetElement').classList = null;I haven't noticed any adverse effects when setting it to null in various browsers like Firefox, Brave, Safari, and Chrome.
