JavaScript Find <style> tag by id or attribute find style attribute using jquery,jquery find style attribute,jquery

I would like to dynamically remove or disable a <style> tag

that looks like this

<style type="text/css" id="cssx/portal/simple-sidebar.css" designtr="cssx/portal/simple-sidebar.css">


#wrapper {
    padding-left: 0;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

#wrapper.toggled {
    padding-left: 250px;
}

#sidebar-wrapper {
    z-index: 1000;
    position: fixed;
    left: 250px;
    width: 0;
    height: 100%;
    margin-left: -250px;
    overflow-y: auto;
    background: #000;
    -webkit-transition: all 0.5s ease;
    -moz-transition: all 0.5s ease;
    -o-transition: all 0.5s ease;
    transition: all 0.5s ease;
}

</style>

if I have the id or my own defined designtr property, I can't seem to disable or remove it like so:

        var id = 'x';
        var designtr = 'x';

        document.getElementById(id).disabled = true;  //doesn't work, throws an error saying element is null
        $('style[designtr="' + designtr + '"]').remove();   //doesn't work, although strangely no error thrown

I read somewhere that even with HTML5 style tags can't have a valid id attribute.

All I want to do is either remove or disable a style tag, given some unique id that I have in hand.

Answer:1

Works like a charm:

document.getElementById('remove').onclick = function () {
  document.getElementById('styl').remove();
};

<div>Some Div Content</div>
<button id="remove">remove</button>
<style id="styl">div{background-color: red}</style>
