refresh a page with jQuery

here we provide code for refresh a page with jQuery $('#something').click(function() {
    location.reload();
});



The reload() function takes an optional parameter that can be set to true to force a reload from the server rather than the cache. The parameter defaults to false, so by default the page may reload from the browser's cache.

How to change color of SVG image using CSS

First, use an IMG tag in your HTML to embed an SVG graphic. I used Adobe Illustrator to make the graphic.


This is just like how you'd embed a normal image. Note that you need to set the IMG to have a class of svg. The 'social-link' class is just for examples sake. The ID is not required, but is useful.

Then use this jQuery code (in a separate file or inline in the HEAD).

    /*
     * Replace all SVG images with inline SVG
     */
        jQuery('img.svg').each(function(){
            var $img = jQuery(this);
            var imgID = $img.attr('id');
            var imgClass = $img.attr('class');
            var imgURL = $img.attr('src');

            jQuery.get(imgURL, function(data) {
                // Get the SVG tag, ignore the rest
                var $svg = jQuery(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');

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

            }, 'xml');

        });


What the above code does is look for all IMG's with the class 'svg' and replace it with the inline SVG from the linked file. The massive advantage is that it allows you to use CSS to change the color of the SVG now, like so:


The jQuery code I wrote also ports across the original images ID and classes. So this CSS works too:
