Change fill of inline SVG path on click

Question

I'm new to html etc and I'm trying to make a SVG map where it is possible to change the fill color of a country (a path) by clicking on it.

So far I managed to change the fill when hovering over a path, but I can't get it to work that the color is toggled on click. So, the goal is that the user can hover over a path and is highlighted. When he clicks, the fill is changed to some value ("marked"), and again changed back to the original fill color after a second click. How can I implement the toggling of the fill color when a path is clicked?

Here is part of the html file, only the other svg paths are excluded:

This is the css file:

#world-map{
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
path:hover {
  stroke: #339999 !important;
  stroke-width:2px;
  stroke-linejoin: round;
  fill: #002868 !important;
  cursor: pointer;
}

And as main.js I so far tried lots of things, but none of them work. I think that it could be something along the lines of this, but I'm not sure:

$('path').on("click", function(e) {
    $(this).html({ fill: "#ff0000" });
});

Any help would be very appreciated!

You could do this through class manipulation on click (using class attribute change since jquery's addClass won't work with SVG, see this for more details). Very naive implementation will be as follows below:

$('path').on("click", function() {
    $('path.selected').attr("class", "");
    $(this).attr("class", "selected");
});

path {
  cursor: pointer;
  fill: grey
}
.selected {
  fill: #002868;
  stroke: #339999;
  stroke-width: 2px;
  stroke-linejoin: round;;
}

Thanks! This is pretty much exactly what I am looking for but I somehow still can't get it to work. In the script tag in the html file I need to put the path of my main.js file, correct? – DK2AX May 06 '18 at 16:20
Yep, you need also to make sure jquery library is imported. Plus I would always place SVG inside of a div container with clear width/height (according to your needs). What doesn;t work for you? what error? – Sergey Rudenko May 06 '18 at 16:27
Ah, so that might be the problem actually. I am just using a text editor, so there aren't any error messages, but the webpage just doesn't react to the clicks. How do I import the jquery library? – DK2AX May 06 '18 at 16:36

Ahh, got it! When the jQuery library is imported, this solution also works perfectly. This [link here](https://www.digitalocean.com/community/tutorials/an-introduction-to-jquery) clarified how to do that, in case someone stumbles on the same problem. – DK2AX May 06 '18 at 16:41

If you can't use Jquery as Sergey mentioned, you can use plain Javascript instead, using the classList.toggle() method.

// first we get all the path elements and put them in an array
let paths = document.getElementsByTagName('path')

//now we can loop over the array and add an eventlistener to each path in the array
// it listens to the 'click' event and then runs function toggleClass()
for(let i=0; i<paths.length; i++){
    paths[i].addEventListener('click', toggleClass)
}

// In the function toggleClass we can toggle the 'clicked' class.
function toggleClass() {
    this.classList.toggle('clicked')
}

path {
  cursor: pointer;
  fill: grey
}

.selected {
  fill: #002868;
  stroke: #339999;
  stroke-width: 2px;
  stroke-linejoin: round;;
}

.clicked {
  fill: #ff0000;
}

Great, this works nicely, thanks! I found out that the script tag needs to be after the svg tag, this was causing also some problems before. — DK2AX, May 06 '18 at 16:37

Another option is to use jQuery to toggle between two classes:

$('path').on("click", function() {
    var n = $(this).attr("class");

    if(n == "clicked") {
     $(this).attr("class", "");
    }
    else {
     $(this).attr("class", "clicked");
    }
});

#world-map{
  display: block;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
}
path:hover {
  stroke: #002868 !important;
  stroke-width:2px;
  stroke-linejoin: round;
  fill: #002868 !important;
  cursor: pointer;
}
.clicked {
  fill: #ff9800;
  stroke: #ff9800;
  stroke-width: 2px;
  stroke-linejoin: round;;
}

Maybe try:

svg:hover path {
    "your css"
}

Oow, you already had that working? Sry for reading post wrong

<script>

$('path').on("click", function() {
    $(this).css({ fill: "#ff0000" });
});

</script>

This little sample is the best i can do :) Not so well at js, but maybe you can improve.

Yeah, that's for hovering, that works already. The pretty much same thing for clicking is causing me a headache – DK2AX May 06 '18 at 14:59
Did you try doing this via a class add/removal on click? – Sergey Rudenko May 06 '18 at 15:23
