I'm having trouble changing the colour of an svg image with jquery or vanila javascript. I've tried a couple of things but nothing seems to work, the original colour is black and i can change it if i open the svg image in my IDE and add/change the fill attribute. But not with JS. What am I doing wrong? Other lines of code work fine so it is not a problem with the files or so.
So far i've tried these lines of codes and put id on the img tag aswell as the svg element it self
html:
<img src="import/splash.svg">
JS:
$('#myId').css({fill:"#f8b9d4"});
$("myId").attr("fill", "yellow");
document.getElementById("myId").setAttribute("fill", "#f8b9d4");

I'd say it's because you're using an <img> tag rather than putting the <svg> directly in the HTML.
If you cannot put the <svg> directly in your HTML, embed it using the <object> tag, e.g. like this:
<object id="img" data="test.svg" type="image/svg+xml">Your browsser doesn't support SVG</object>
Then, you can access elements inside the <object> like this:
document.getElementById("img").contentDocument.getElementById("myId").setAttribute("fill", "#f8b9d4");
Your Jquery css works fine. You don't need to have an empty fill="" attribute on the path.
Note: Scroll down on the code snippet to see result, your viewbox is a bit big :)
$('#myId').css({fill:"blue"});

I have simple html like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<svg id="svg" viewBox="0 0 594 600" preserveAspectRatio="xMinYMin meet">
<rect id="rect" fill="#98df8a" style="width: 100px; height: 100px;">
</rect>
</svg>
</body>
</html>
When i use: window.getComputedStyle(document.getElementById('rect')), I get the value of both width and height to be auto and not 100px like what I expected.
Is this how it should be? If so, how can i make it to return 100px ?
I need this function to turn all my styles defined in the external css into inline style attribute for svg elements so that I can export it later.
You could just use document.getElementById('rect').style.height and document.getElementById('rect').style.width and if you want to handle an arbitrary list of styles something like this:
var exportStyleKeys = ['width', 'height'];
var rect = document.getElementById('rect');
var exportStyles = exportStyleKeys.reduce((styles, styleKey) => {
styles[styleKey] = rect.style[styleKey];
return styles;
}, {});
JSFiddle
window.document.getElementById('rect').style.width will return you the inline css width attribute.
Try the blow code
var rect = window.document.getElementById('rect');
console.log(rect.style.width);

I just start learning SVG. got this example code from Manipulating SVG Documents Using ECMAScript (Javascript) and the DOM. I change it a little:
<!DOCTYPE html>
<html>
<body>
<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="300" height="300">
<script type="text/ecmascript">
<![CDATA[
function changeRectColor(evt) {
var red = Math.round(Math.random() * 255);
evt.target.setAttributeNS(null,"fill","rgb("+ red +","+ red+","+red+")");
}
]]>
</script>
<g id="firstGroup">
<rect id="myBlueRect" width="100" height="50" x="40" y="20" fill="blue" onclick="changeRectColor(evt)"/>
<text x="40" y="100">Click on rectangle to change it's color.</text>
</g>
</svg>
</body>
</html>
It works just fine. I move to separated SVG file, then js code stop working:
<!DOCTYPE html>
<html>
<body>
<object type="image/svg+xml" data="exampl3a.svg" />
<script type="text/ecmascript">
<![CDATA[
function changeRectColor(evt) {
var red = Math.round(Math.random() * 255);
evt.target.setAttributeNS(null,"fill","rgb("+ red +","+ red+","+red+")");
}
]]>
</script>
</body>
</html>

<text x="40" y="100">Click on rectangle to change it's color.</text>
</g>
</svg>
what should I do?
Thanks

If you put svg into a different file, then it will be in another document, and you'll need to bind to that document, using getSVGDocument. And yes, this will still not work in Chrome for local files (only for the website, or unless Chrome is run with corresponding command-line switch).

This was my experience: It getSVGDocument works on a server (Github worked), but not for local files. If you have an older computer (Windows XP) it will work on that, too.
Is there a way, possibly without JS, do generate a responsive SVG where the slanted border does not stretch with the width? Please do not reply with "use CSS" because I need to create a complex mask that is simply not possible with CSS alone.

change preserveAspectRatio to "xMaxYMax" to avoid stretching and height to "100%" let the rectangle grow if needed for large screen
