Sharethis a11y Functionality jQuery

sharethis.js

jQuery(document).ready(function($) {
	setTimeout(function(){
	//--------------------------
	// SHARETHIS a11y
	//--------------------------
		
	// Loop through an array of data-network names
	['facebook', 'twitter', 'pinterest'].forEach(function( platform ) {
		// Adds a11y to sharing icons
		$('.st-btn[data-network="' + platform + '"').attr({
			'title' : 'social ' + platform.charAt(0).toUpperCase() + platform.slice(1) + '',
			'aria-label' : 'Open ' + platform + ' sharing modal',
			'tabindex' : '0',
			'role' : 'content-info',
		});

		// Adds enter key functionality to work like a click
		$('.st-btn[data-network="' + platform + '"').keypress( function( e ) {
			if ( e.which && e.which == 13 ) { //  13 is character code for enter
				// event.preventDefault();
				$(this).click();
			}
		});
	});
		
// 	// Checks to see if container is empty because of browser social blocking
	if ($('.sharethis-inline-share-buttons').is(':empty')) {
		$('.share').addClass('no-social');
		$('.sharethis-inline-share-buttons').append('<div class="no-social">Your browser may be blocking social sharing.</div>');
	}
	}, 100);
}

This adds tabindex to add focus on tab selection and enter key functionality so it mimics a mouse click to trigger to popup window.

Thanks to @zachfedor for the assist on streamlining this!
