Version without jQuery?

I realised that the site I am working with has jQuery enabled when I don’t use it at all, so I disabled. I found out everything worked but no inline SVG where added.

The SVG Support javascript svgs-inline-min.js located at /wp-content/plugins/svg-support/js/min/svgs-inline-min.js use jQuery functions.

What about providing an option to enable a jQuery free plugin version?

The final script would be bigger but still smaller than jQuery script.

The non minified code is:

jQuery(document).ready(function ($) {

	// Polyfill to support all ye old browsers
	// delete when not needed in the future
	if (!String.prototype.endsWith) {
		String.prototype.endsWith = function(searchString, position) {
			var subjectString = this.toString();
			if (typeof position !== 'number' || !isFinite(position) || Math.floor(position) !== position || position > subjectString.length) {
				position = subjectString.length;
			}
			position -= searchString.length;
			var lastIndex = subjectString.lastIndexOf(searchString, position);
			return lastIndex !== -1 && lastIndex === position;
		};
	} // end polyfill

	// Another snippet to support IE11
	String.prototype.endsWith = function(pattern) {
		var d = this.length - pattern.length;
		return d >= 0 && this.lastIndexOf(pattern) === d;
	};
	// End snippet to support IE11

	// Check to see if user set alternate class
	var target  = ( cssTarget !== 'img.' ? cssTarget : 'img.style-svg' );

	$(target).each(function(index){
		var $img = jQuery(this);
		var imgID = $img.attr('id');
		var imgClass = $img.attr('class');
		var imgURL = $img.attr('src');

		if (!imgURL.endsWith('svg')) {
			return;
		}

		$.get(imgURL, function(data) {

			// Get the SVG tag, ignore the rest
			var $svg = $(data).find('svg');

			var svgID = $svg.attr('id');

			// Add replaced image's ID to the new SVG if necessary
			if(typeof imgID === 'undefined') {
			    if(typeof svgID === 'undefined') {
					imgID = 'svg-replaced-'+index;
					$svg = $svg.attr('id', imgID);
				} else {
					imgID = svgID;
				}
			} else {
				$svg = $svg.attr('id', imgID);
			}

			// Add replaced image's classes to the new SVG
			if(typeof imgClass !== 'undefined') {
			    $svg = $svg.attr('class', imgClass+' replaced-svg svg-replaced-'+index);
			}

			// Remove any invalid XML tags as per http://validator.w3.org
			$svg = $svg.removeAttr('xmlns:a');

			// Replace image with new SVG
			$img.replaceWith($svg);

			$(document).trigger('svg.loaded', [imgID]);

		}, 'xml');
	});

});
