Changing color of an SVG path using JavaScript (JS Color library)

Question

I'm trying to modify an SVG image through the JS Color library. When I pass the ID of the SVG image to my JavaScript function, the function appropriately changes the background of the "entire" SVG background as a whole. But, when I pass the SVG path ID to that function, it doesn't do anything. See code below for reference:

<head>
<body>

<script src="jscolor.js"></script>

<p>'onchange' fires after the mouse button is released

<p>Rectangle color:
<input class="jscolor" onchange="update(this.jscolor)" value="cc66ff">

<p id="rect" style="border:1px solid gray; width:161px; height:100px;">

I want to update the paths inside my SVG and change the color based on the color the user selects from a palette. It does recognize the color and changes it if I provide the SVG id as I said; but fails to do so for the path ID. I guess I need to "tell" the JS function that there is a path. How should I proceed?

Hej!

It must be style.fill instead of style.backGroundcolor for paths.

this.jscolor is probably meant to use that library. Anyway, to get this example to work, use update(value). Value refers to the value of the input element. Then of course you have to fit it to your needs and make it work with this library.

<input class="jscolor" onclick="update(value)" value="cc66ff">
