Use script tag inside SVG in React?

I have some SVG-s that are equipped with scripts inside (for handling the onClick event), like:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:svgjs="http://svgjs.dev/svgjs" width="200" height="200">

</linearGradient>

<script type="application/ecmascript"><![CDATA[
function triangle_click(evt){
const fgPath = evt.target;
const newVal = fgPath.getAttribute('stroke-dasharray') === '0' ? '30 20' : 0;
fgPath.setAttribute('stroke-dasharray',newVal);
}
]]> </script>
<path d="M 20,180 L 100,20 L 180,180 Z"
stroke="#00ffff" stroke-width="3"
fill="url(#fillColor)"
mask="url(#myMask2)">
<animate
attributeName="stroke-dashoffset"

/>
</path>
<path id="fgPath" d="M 20,180 L 100,20 L 180,180 Z"

onclick="triangle_click(evt)"
>
<animate
attributeName="stroke-dashoffset"
values="0;500"
dur="5s"
repeatCount="indefinite"
/>
</path>
</svg>
Now, when I add this SVG into my react app, it throws an error on the 'onClick' event, unless I copy and paste the <script> tag in the inspector, anywhere (Uncaught ReferenceError: triangle_click is not defined at onclick).
Does that mean this script tag was not read initially, that's why it doesn't find it at first place?
Thanks,
M

I found out the issue was that I inserted the element as innerHTML. The answer can be found here: Executing <script> elements inserted with .innerHTML

SVG Filter does not binds to its icon

I have a simple SVG icon, where I need to set the linearGradient for it. I'm trying to make it by specifying id of filter to the SVG body, but it does not wok, because in such way I got an empty SVG icon at all... Why?
<svg xmlns="http://www.w3.org/2000/svg" class="default___3oPC0 " style=" fill: url(#chat); filter: url(#chat); " fill="black" stroke="black" stroke-width="0" width="21px" height="21px" viewBox="0 0 17 17">

You might need to apply the fill to the path using an ID attached to the gradient
svg {
height: 200px;
}
path {
fill: url(#chat);
}

How to draw a linear gradient circle by svg? [duplicate]

This question already has answers here:
svg multiple color on circle stroke
(3 answers)
Closed 7 years ago.
This is my code, but it's not what I wanted.I hope the color distribution is not symmetrical.
<svg width="300" height="300">
<linearGradient id="linearColors" x1="0" y1="0" x2="1" y2="1">
<stop offset="5%" stop-color="#01E400"></stop>
<stop offset="25%" stop-color="#FEFF01"></stop>
<stop offset="40%" stop-color="#FF7E00"></stop>
<stop offset="60%" stop-color="#FB0300"></stop>
<stop offset="80%" stop-color="#9B004A"></stop>
<stop offset="100%" stop-color="#7D0022"></stop>
</linearGradient>
<circle r="120" cx="150" cy="150" class="external-circle" stroke-width="4" fill="none" stroke="url(#linearColors)"></circle>
</svg>
I need an effect like this.

before check: circle-drawing-with-svgs-arc-path .... my solution is simple: i divided circle into six arcs, each arc with own lineal gradient
math explanation:
angle = 360 / 6 = 60
Math.sin(Math.PI*60/180)*120 == 103.9230
Math.cos(Math.PI*60/180)*120 == 60.0000

Smoothly change the filling of a SVG

I'm using javascript to change the color of a svg. This changes my <linearGradient> filling :
My problem is, that it is changing very rapidly.
Is there any way to have a "smooth" flow between the colors? I tried to use the jquery anim() method but it wouldn't work because of the SVG-DOM.
Edit: More source code. In the end, it's pretty simple. I get the stop elements of my svg and calculate a new rgb value. I then set the rgb value as the new stop-color of the stop element
js:
var gradient = $('#upper').children('stop');
var firstValue = 'stop-color:rgb('+top[0]+','+top[1]+','+top[2]+')';
var secondValue = 'stop-color:rgb('+bottom[0]+','+bottom[1]+','+bottom[2]+')';
gradient[0].setAttribute('style',firstValue);
gradient[1].setAttribute('style',secondValue);
html
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1 1" preserveAspectRatio="none">
<defs>
<linearGradient id="upper" gradientUnits="userSpaceOnUse" x1="0%" y1="0%" x2="0%" y2="100%">
<stop style="stop-color:rgb(107,186,112);stop-opacity:1" offset="0"/>
<stop style="stop-color:rgb(107,186,112);stop-opacity:1" offset="1"/>
</linearGradient>
</defs>
<rect x="0" y="0" width="1" height="1" fill="url(#upper)" opacity="0.6" />
</svg>

Depending on the actual scenario, this could be solved with pure SMIL animation:
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1 1" preserveAspectRatio="none">
<defs>
<linearGradient id="upper" gradientUnits="userSpaceOnUse" x1="0%" y1="0%" x2="0%" y2="100%">
<stop stop-color="rgb(107,186,112)" offset="0">
<animate attributeType="CSS" attributeName="stop-color" id="animate0"
dur="2s" begin="rect0.click" fill="freeze" to="rgb(0,255,0)"/>
</stop>
<stop stop-color="rgb(107,186,112)" offset="1">
<animate attributeType="CSS" attributeName="stop-color"
dur="2s" begin="animate0.begin" fill="freeze" to="rgb(255,0,0)"/>
</stop>
</linearGradient>
</defs>
<rect x="0" y="0" width="1" height="1" fill="url(#upper)" opacity="0.6" id="rect0"/>
</svg>
I this case the animation is triggered by a click on the rectangle.
Specific colors can also be set by JavaScript and the animation can be triggered by JavaScript:
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1 1" preserveAspectRatio="none">
<defs>
<linearGradient id="upper" gradientUnits="userSpaceOnUse" x1="0%" y1="0%" x2="0%" y2="100%">
<stop stop-color="rgb(107,186,112)" offset="0">
<animate attributeType="CSS" attributeName="stop-color" id="animate0"
dur="2s" begin="indefinite" fill="freeze"/>
</stop>
<stop stop-color="rgb(107,186,112)" offset="1">
<animate attributeType="CSS" attributeName="stop-color"
dur="2s" begin="animate0.begin" fill="freeze"/>
</stop>
</linearGradient>
</defs>
<rect x="0" y="0" width="1" height="1" fill="url(#upper)" opacity="0.6"/>
<script type="text/javascript">
var gradientColors = [[255,0,0],[255,255,0]];
var animateElements = document.getElementsByTagName("animate");
for (var i=0; i<2; i++) {
animateElements[i].setAttribute(
"to",
"rgb("+gradientColors[i].join(",")+")"
);
}
animateElements[0].beginElement();
</script>
</svg>
Whether these solutions are practical for you depends on whether the targeted browsers support SMIL animation.
