How to: show/hide a widget in WordPress with jQuery

In a previous post I talked about how to show/hide a single div html code with a search inside. Today I’d like to show you how I implemented jQuery into my new theme.

Published

on

As seen in the current theme, I am using jQuery to animate the show/hide or as known as the css style display: none;.

Since I am using a custom child theme on my site, and have Hybrid theme as my parent, the widgets or sidebar section is different than may be in your theme. But just apply the the style’s as follows to your theme.

First make sure that your WordPress site is calling jQuery, by plugging in this code into your header.php file above the <?php wp_head(); ?> text:

<?php wp_enqueue_script('jquery'); ?>

Then anywhere above the </head >, plug this code in:

<script type="text/javascript">
function toggleWidgets() {
	$('#primary h3.widget-title').addClass('plus');

	$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

}
$(document).ready(function() {
	toggleWidgets();
}
</script>

That’s it. Pretty simple huh.

So lets go over what the code does.

$('#primary h3.widget-title').addClass('plus');

This line finds all <h3> tags with the class widget-title inside the ID parameter of #primary and adds a class of plus.

Then

$('#primary h3.widget-title').click(function() {
		$(this).toggleClass('plus').toggleClass('minus').next().toggle(180);
	});

Will apply a click function. When the H3 tag is clicked it will remove the class plus and add the class minus.

Then the code that says .next will then toggle the “next” element after the <h3> title.

            Doesn’t work for me. I don’t see the class added. I have the last jquery installed, I even tried the noConflict just in case and nothing.

Remove the title attribute using jQuery

Published

on

In WordPress, when you use wp_page_menu your anchor attribute’s usually carry a title with the same name. I’m not sure if it’s correct to do this, but it bother me when I hover over a page menu navigation link and I get a hover of the title.

So on my site I used jQuery to remove the title:

$("#nav a").removeAttr("title");

Pretty simple huh?

How to: Open external links in a new window

Published

on

Over the weekend, I attended WordCamp Denver, and I was asked by John Hawkins how to force links to open in a new tab with out editing the source code. So, today lets learn a simple jQuery trick to open all external links in your site in a new tab or window. We are going to make sure you have jQuery active on your site, you can do this easily in WordPress, since it’s bundled with the latest installations. Use this code in your header: <?php wp_enqueue_script('jquery'); ?> then, below the wp_head add the following:

<script type="text/javacript">
var $j = jQuery.noConflict();

$j(document).ready(function() {
//external attribute
    $j("a:not([@href*=http://YOURSITE.com/])").not("[href^=#]")
        .addClass("external")
        .attr({ target: "_blank" });
    }
);
</script>

That’s it, just make sure you change the http://YOURSITE.com to your website.

Update

If you like you can remove the var $j = and replace all $j with simply just $

Fixing plugins not compatible with hybrid 0.4.2

Published

on

Hey everyone, as you may have noticed I have a running on the site. While everything almost everything moved over smoothly, there was an issue with how my parent theme striped text in typography. This caused some plugins, like cformsII to not be allowed to print to the screen. Justin had helped to find a fix to filter the hybrid_typography function.

Originally this function filtered out and changed some text that would not validate as XHTML. This had to be removed by running a new function in the child theme’s function.php file.

add_action('init', 'remove_typography');

function remove_typography() {
	remove_filter('the_content', 'hybrid_typography', 11);
}
