将Jquery Toggle转换为Javascript

Question

I am totally new to web programming. I built a slide navigation and wanted to make it slide from the left to the middle. The thing is I just found a Jquery code. I tried to look it up by searching on google but the matches didn't match to the thing I was looking for.

Here is the Code:

$('.nav-side .nav-toggle').on('click', function(e){
    e.preventDefault();
    $(this).parent().toggleClass('nav-open');
})

I would like to know if I can translate this into Javascript because I would like to continue using HTML, CSS and Javascript.

Could someone help me out?

Answer 1

In pure JavaScript it should be something like this:

var elements = document.querySelectorAll('.nav-side .nav-toggle');
[].slice.call(elements).forEach(function(element) {
    element.addEventListener('click', function() {
        element.parentNode.classList.toggle('nav-open');
        return false;
    }, false);
});

You can use classList.toggle() :

document.getElementsByClassName('nav-toggle')[0].addEventListener('click', function(e){
    e.preventDefault();
    e.target.parentNode.classList.toggle('nav-open');
});

Here is a codepen example.

Answer 3

This is pure javascript code

function clickHandler(dom)
{
    dom.addEventListener('click', function(e) {
        dom.parentNode.classList.toggle('nav-open');
        return false;
    }, false);
}
document.querySelector('.nav-side .nav-toggle').map(clickHandler);

Answer 4

Here is your HTML

<a href="#" class="nav-toggle" onclick="toggleFunction(this)">Toggle</a>

And Here is your javascript which adds style="display:none;" when the parent style="display:block;". vice versa

<script>
function toggleFunction(elem){
    var parent = elem.parentNode;
    if(hasClass(parent, 'nav-open')){
         parent.classList.remove('nav-open');
    }else{
        parent.className += " nav-open";
    }
}
function hasClass(element, cls) {
    return (' ' + element.className + ' ').indexOf(' ' + cls + ' ') > -1;
}
</script>

I just got it by writing:

function clickHandler(dom){
        dom.parentNode.classList.toggle('nav-open');
        return false;
}

But thanks everyone for the answers :)
