I am trying to add an SVG g element to an SVG tag using JavaScript. The g element is defined in a template tag. It is in a template tag as I want to reuse it many times.
<!DOCTYPE html>
<html>
<head>
<title>Template Example</title>
<style media="screen">
svg {
margin: auto;
}
g {
stroke:black;
stroke-width:2px;
fill:none;
}
</style>
</head>
<body>
<template>
<g>
<line x1=" 2" y1="2" x2=" 7" y2="7" ></line>
<line x1="25" y1="2" x2="20" y2="7" ></line>
<path class="botLeft" d="m 1,26 6,-6" ></path>
<path class="botRite" d="m 26,26 -6,-6" ></path>
<rect x="1" y="1" rx="3" ry="3" width="25" height="25" ></rect>
<path class="rectIn" d="m 7,7 0,13 13,0 0,-13 z" style="fill:gray;" ></path>
</g>
</template>
<svg width="80%" height="80%" ></svg>
<script type="text/javascript">
var temp = document.getElementsByTagName("template")[0];
var clon = temp.content.cloneNode(true);
var svg = document.getElementsByTagName("svg")[0];
svg.appendChild(clon);
</script>
</body>
</html>
This code adds the g element to the DOM in the correct place, but the element is not rendered.
After reading other posts regarding SVG, I think this is because this is not a normal HTML element, but an SVG Element.
How do I advise the browser to treat this as an SVG element?
I have seen some remarks hinting at namespaces but can not understand what is needed.
Any pointers will be appreciated ;-)
If you put the elements in the SVG itself and embed them with a <defs> tag instead of a <template> tag they will all get created in the right namespace and also be invisible.

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 would like to dynamically replace a text element of an svg object from a local text file. Below my files text et svg:
text file:
<p id="p1">It works fine</p>
text svg:
<svg width="640" height="480" xmlns="http://www.w3.org/2000/svg" xmlns:svg="http://www.w3.org/2000/svg">
<rect id="svg_1" height="87" width="162" y="188" x="130" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke-width="5" stroke="blue" fill="yellow"/>
<text xml:space="preserve" text-anchor="start" font-family="serif" font-size="24" id="divA" y="240" x="313" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke-width="0" stroke="#000000" fill="blue"> </text>
</svg>
It works fine with the div or if I put the value, for example dog, for the element svg to modify. below mon fichier html:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var x = $("#divA").load("demo_test.txt #p1");
var y = $("#div1").load("demo_test.txt #p1");
document.getElementById("div1").textContent = y;
var svg = document.getElementById("textsvg");
var svgDoc = svg.contentDocument;
svgDoc.getElementById("divA").textContent = "dog";
});
</script>
</head>
<body>
<div id="div1"><h2>PSU0 to PDU-A G0-2</h2></div>
<object id="textsvg" width="600" height="480" type="image/svg+xml" data="essai.svg"></object>
</body>
However, when I put the variable y for the text element svg I have the message "[object Object]" instead of the message "It works fine". Below the html file:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
var x = $("#divA").load("demo_test.txt #p1");
var y = $("#div1").load("demo_test.txt #p1");
document.getElementById("div1").textContent = y;
var svg = document.getElementById("textsvg");
var svgDoc = svg.contentDocument;
svgDoc.getElementById("divA").textContent = x;
});
</script>
</head>
<body>
<div id="div1"><h2>PSU0 to PDU-A G0-2</h2></div>
<object id="textsvg" width="600" height="480" type="image/svg+xml" data="essai.svg"></object>
</body>
Can you help me.
Thanks,
B.R,
<script>
$(document).ready(function(){
$("#divA").html("Gorillaz Inc");
});
</script>
This works with jquery
Full example: http://codepen.io/anon/pen/pRRgaP
Note: I didn't use files, I just updated the svg dynamically
I solved part of my problem. I have directly embedded the "svg" into my html.
I noticed that by downloading the text file without the tags: demo_text1.txt the div appears well and the text svg:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$("#div1").load("demo_test.txt #p2");
$("#divA").load("demo_test1.txt");
});
</script>
</head>
<body>
<div id="div1"><h2 style="color:blue">PSU0 to PDU-A G0-2</h2></div>
<svg width="800" height="480" xmlns="http://www.w3.org/2000/svg" xmlns:svg="http://www.w3.org/2000/svg">

<text xml:space="preserve" text-anchor="start" font-family="serif" font-size="14" id="divA" y="67" x="175" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke-width="0" stroke="#000000" fill="blue"> </text>
</svg>
</body>
</html>
fichier text:demo_test.txt
<p id="p1" >It works fine</p>
<p id="p2" style="color:blue">I use the local text file "demo_test.txt".The "div" works fine with tags</p>
fichier text:demo_text1.txt
I use the local text file "demo_test1.txt".
The text of svg works fine without tag but doesn't work with tags
Screen display ok:
enter image description here
However, by pointing the text svg to the text file with the tags (demo_test.txt, it does not work:
Screen not ok:
enter image description here
I created simple SVG document and open it in Chrome and FF
<?xml version="1.0" standalone="no"?>
<svg xmlns="http://www.w3.org/2000/svg"
width="4in" height="3in">
<g>
<title>Company sales by region</title>
</g>
</svg>
Why does document.title return ""?
According to standard https://www.w3.org/TR/html51/dom.html#dom-tree-accessors
document . title [ = value ]
Returns the document’s title, as given by the title element for HTML and as given by the SVG title element for SVG.
Try document.title on this instead:
<svg xmlns="http://www.w3.org/2000/svg"
width="4in" height="3in">
<title>Company sales by region</title>
</svg>
The spec says:
If the document element is an SVG svg element, then let value be the child text content of the first SVG title element that is a child of the document element.
So the reason document.title returns "" for the snippet in the question is that in that snippet the title element isn’t a child of the document element (the svg element).
To display a hint message when you hover over an svg element, you need to wrap it with group tags.
You have group tags <g> but inside is empty.
See the example below where the prompt will be displayed:
<svg width="50%" height="50%" viewBox="0 0 400 400">
<g id="titleRect">
<title> This is a green square </title>
<rect id="rect1" x="10" y="100" width="100" height="100" fill="yellowgreen" />
</g>
<g id="titleCircle">
<title> This is a purple circle. </title>
<circle id="circle1" cx="200" cy="150" r="50" fill="purple" />
</g>
</svg>
Multi-line tooltip
To get a multi-line tooltip, you must use a line break inside the <title> tags
html, body, svg {
margin: auto;
width: 100vmin;
display: block;
}
<svg viewBox="-4 -4 8 8">
<g>
<title>Multiline
the tooltip is
very easy!</title>
<circle r="4" fill="purple" />
</g>
</svg>
The second way to get a multiline tooltip
This method uses nested tags <title>
<title>
<title> ⧉ Atom properties </title>
<title> ⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯ </title>
<title> Name: oxygen </title>
<title> Atomic mass (molar mass) :15,99903 </title>
<title> Atomic radius 60 (48) пм </title>
<title> ⧉ Chemical properties </title>
<title>
Hover cursor the center circle and see a multiline tooltip.
