I've created a little page just as this one here:
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<script type="text/javascript">
function test() {
executeAnimation();
}
</script>
</head>
<body>
<h1>Tester</h1>
<embed src="test.svg" type="image/svg+xml" />
<hr />
<input type='button' value='Test' onclick='test()' />
</body>
</html>
The test.svg looks like this:
<?xml version="1.0" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20010904//EN"
"http://www.w3.org/TR/2001/REC-SVG-20010904/DTD/svg10.dtd">
<svg id="testSvgId" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="950" height="900">
<title>Title</title>
<desc>Desc</desc>
<defs>
<script type="text/javascript">
<![CDATA[
function executeAnimation () {
document.getElementById('anim').beginElement();
}
]]>
</script>
</defs>
<ellipse cx="500" cy="1090" rx="600" ry="0" fill="rgb(94,114,54)">
<animate id="anim" attributeType="XML" attributeName="ry" begin="indefinite" dur="2s" from="0" to="350" fill="freeze" />
</ellipse>
</svg>
As you can see, I want to call from JavaScript in the HTML page the function executeAnimation() which is defined insite the SVG image. This actually does not work.
I also tried this:
<svg onload='onloadFunction()'...>
...
function onloadFunction() {
alert('i am loading');
window.executeAnimation = executeAnimation();
}
This was suggested in another forum, but this did also not work (window.executeAnimation was undefined from outside).
What would be the real correct way to do this?
Without seeing the source of your .svg, it's impossible to answer specifically...

With javascript, I intend to generate a svg which will show each yAxis grid line after the text. e.g.
To programmatically generate this, my approach was to generate a clipPath with a rect that starts at x=text.x+text.width and same y,width as the lines and height=text.height and have it apply on each line.
This is what I tried so far
const svgns = 'http://www.w3.org/2000/svg';
document.querySelectorAll('.tick>line').forEach(
(a, i) => {
const defs = document.createElementNS(svgns, 'defs');
document.querySelector('svg').appendChild(defs);
const clipPath = document.createElementNS(svgns, 'clipPath');
clipPath.setAttribute('id', `clip${i}`);
defs.appendChild(clipPath);
const data = document.querySelectorAll('.tick>text');
const rect = document.createElementNS(svgns, 'rect')
rect.setAttribute('x', `${data[i].getBoundingClientRect().x+data[i].getBoundingClientRect().width}`);
rect.setAttribute('y', `${a.getBoundingClientRect().y}`);
rect.setAttribute('height', `${data[i].getBoundingClientRect().height}`)
rect.setAttribute('width', `${a.getBoundingClientRect().width}`)
clipPath.appendChild(rect);
a.style.setProperty('clip-path', `url(#clip${i})`)
}
)

I can't figure out what I am doing wrong in this. it does not return what I was intending.
Also, is there a built-in method currentyl exists in javascript that does union/combine/intersect/subtract operations of svg elements?
This worked for me
const svgns = 'http://www.w3.org/2000/svg';
document.querySelectorAll('.tick>line').forEach(
(a,i)=>{
const defs = document.createElementNS(svgns, 'defs');
document.querySelector('svg').appendChild(defs);
const clipPath = document.createElementNS(svgns, 'clipPath');
clipPath.setAttribute('id',`clip${i}`);
defs.appendChild(clipPath);
const data = document.querySelectorAll('.tick>text');
const rect = document.createElementNS(svgns, 'rect')
rect.setAttribute('x', `${data[i].getComputedTextLength()}`);
//rect.setAttribute('y', `${a.getBoundingClientRect().y}`);
rect.setAttribute('height', `${data[i].getBBox().height}`)
rect.setAttribute('width', `${a.x2.baseVal.value-a.x1.baseVal.value}`)
clipPath.appendChild(rect);
a.style.setProperty('clip-path',`url(#clip${i})`)
}
)
const svgns = 'http://www.w3.org/2000/svg';
document.querySelectorAll('.tick>line').forEach(
(a,i)=>{
const defs = document.createElementNS(svgns, 'defs');
document.querySelector('svg').appendChild(defs);
const clipPath = document.createElementNS(svgns, 'clipPath');
clipPath.setAttribute('id',`clip${i}`);
defs.appendChild(clipPath);
const data = document.querySelectorAll('.tick>text');
const rect = document.createElementNS(svgns, 'rect')
rect.setAttribute('x', `${data[i].getComputedTextLength()}`);
//rect.setAttribute('y', `${a.getBoundingClientRect().y}`);
rect.setAttribute('height', `${data[i].getBBox().height}`)
rect.setAttribute('width', `${a.x2.baseVal.value-a.x1.baseVal.value}`)
clipPath.appendChild(rect);
a.style.setProperty('clip-path',`url(#clip${i})`)

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 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:

Can you help me.
Thanks,

$("#divA").html("Gorillaz Inc");
});

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:

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:

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>

<![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>

It works just fine. I move to separated SVG file, then js code stop working:

what should I do?

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).

var obj = document.getElementById('mySvg');
obj.addEventListener('load', function() {
var svgDoc= obj.getSVGDocument();
var elem = svgDoc.getElementById("myBlueRect");
elem.addEventListener('click', changeRectColor);
});
</script>
</body>
</html>
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.
I have 3 SVGs shown below. I can only change the color of the inline SVG. Any ideas why? (Code hosted on IIS)

I am pretty sure you can't style externally loaded SVGs with css. Why not cut and paste the code from the external SVG into your html like the other two you have?
This is a great resource for information about using SVGs: https://css-tricks.com/using-svg/
