VisualizaçõesExternal js script won't work on pages loaded with jQuery
I'm trying to use jQuery to load html posts into my main html page and have external scripts work on them.
I have this script (load.js) to load posts into my index.html page:
$(document).ready(function () {
$('#header').load("./Includes/include_header.html");
$('#footer').load("./Includes/include_footer.html");
$('#navbar').load("./Includes/include_navbar.html");
// Posts
$('#post3').load("./Posts/2021-11-16-Starting-Book-of-Shaders.html");
$('#post2').load("./Posts/2021-11-12-Lecture-1.html");
$('#post1').load("./Posts/2021-11-12-Start.html");
});
This works and I can get the posts on the page. But scripts that should be changing the "post load" html page won't work.
In my index.html's <head> I have this.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="/Includes/load.js"></script>
<script type="text/javascript" src="https://rawgit.com/patriciogonzalezvivo/glslCanvas/master/dist/GlslCanvas.js" defer></script>
but GlslCanvas.js won't recognize the <canvas> element inside my post (in this example "2021-11-16-Starting-Book-of-Shaders.html"):
<div class="card">
<h2>Getting started with The Book of Shaders</h2>
<p>Testing the very first, most basic example:</p>
<canvas class="glslCanvas" data-fragment-url="/Shaders/test.frag" width="400" height="400"></canvas>
</div>
test.frag file is composed of these few lines:
#ifdef GL_ES
precision mediump float;
#endif
uniform float u_time;
void main() {
gl_FragColor = vec4(0.8196, 0.7804, 0.2235, 1.0);
}
I have tried to include the line:
<script type="text/javascript" src="https://rawgit.com/patriciogonzalezvivo/glslCanvas/master/dist/GlslCanvas.js" defer></script>
inside the posts as well, before and after the <div> but it makes no difference.
What should I do so that the script recognizes the <canvas> element?
Edit:
I can confirm it works by placing <canvas class="glslCanvas" data-fragment-url="/Shaders/test.frag" width="400" height="400"></canvas> directly inside the <body> of my index page. No problems there.
