I want to add all CSS styles of a specific element to its inline style attribute. For example:

I have:

 <div id="d"></div>

and:

#d { background: #444444; width: 50px; height: 20px; display: inline-block; }

Now I want a JavaScript function that turns my div into this:

<div id="d" style="background: #444444; width: 50px; height: 20px; display: inline-block;"></div>

Please help me. And, by the way, I don't want any CSS styles to re-write any existing inline style.

You can do something like this:

function applyStyle(el) {
    s = getComputedStyle(el);

    for (let key in s) {
        let prop = key.replace(/\-([a-z])/g, v => v[1].toUpperCase());
        el.style[prop] = s[key];
    }
}

let x = document.getElementById('my-id');
applyStyle(x);

Where x is the element you want to apply the style to.

Basically this function gets the computed style of the element and then copies each property (like padding, background, color, etc.) to the inline style of the element.

I don't know why you need to do this, but, in my opinion, but it's really dirty approach, I would not personally advise to use it.

Using jQuery it can be done easily. Here is the sample code: If you are new in jQuery and you don't know how to add and work then follow this link

  • That is going to be a lot harder than you think, and you shouldn't really need it.
  • @adeneo Trust me, I really need it.
  • @doniyor As long as other parts of my script are large, I don't want any external libraries in my page, so no JQuery, please.
  • I'm guessing the style is in a stylesheet, so first you have to find the stylesheet or style tag, then you have parse the stylesheet to find the matching selector, then you have to parse all the styles and add them all to the element. Good luck !
  • @adeneo That's not really necessary. I know getComputedStyle does that for me. All I need to do is to get everything from getComputedStyle and put it in element's style. But I can't get it to work.
  • Still not working for me, but I think you're almost there. Honestly, I find this method of rendering any element in canvas really easy, so, for converting any element to svg, I need inline styles. This is what I'm talking about: developer.mozilla.org/en-US/docs/Web/HTML/Canvas/…
  • This is another kind of stuff. I'm not familiar with canvas and you asked about a function to make inline any style applied to an element. That's what I did. I can't help you more than this...
  • That inline style code is all I need. I have written other parts of my code, myself. But your function doesn't seem to work.
  • It works, try to run it on this page with the console on the element #answers-header, and you'll see that all the style will be added in the dom. Here is a screenshot: i.imgur.com/3I3REQn.jpg
  • Yeah! It works! For some reason, it doesn't work for me. Maybe the problem is with my code, but you've earned a +1 anyways. Thanks.
