Convert Image Tags Into Inline SVGs (SVG Inliner Function)

Allure Web Solutions Code Snippet

This function converts all image tags with an SVG image in it’s source into an inline SVG. This is useful for having clean HTML, but still gaining benefits of inline SVG.

// Inline SVGs
$('[src$=".svg"]').each(function () {
    var $img = $(this);
    var imgID = $img.attr('id');
    var imgClass = $img.attr('class');
    var imgURL = $img.attr('src');
    $.get(imgURL, function (data) {
        // Get the SVG tag, ignore the rest
        var $svg = $(data).find('svg');
        // Add replaced image's ID to the new SVG
        if (typeof imgID !== 'undefined') {
            $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');
        }

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

        // Check if the viewport is set, if the viewport is not set the SVG wont't scale.
        if (!$svg.attr('viewBox') && $svg.attr('height') && $svg.attr('width')) {
            $svg.attr('viewBox', '0 0 ' + $svg.attr('height') + ' ' + $svg.attr('width'));
        }
        // Replace image with new SVG
        $img.replaceWith($svg);
    }, 'xml');
});
