Web content update/refresh with jquery and/or ajax

Hi,

I'm trying to figure out a way to refresh content between <div> tags based on a <a href> link press. I have a one page parallax site and have no way of 'refreshing' the page so need to figure out a way to just update/refresh an area.

What I have is three button (via css, not an input button, so something like <span class="button-pricing-nav" style="background-color: #fff;"><a href="js code??>Web Design</a></span>)

<div>
content
</div>

Any help would be appreciated.

Thanks
Karessa

The simple way is to use jQuery .load() function

e.g.
$(".button-pricing-nav").click(function(){
$( "#div-id" ).load( "newcontent.html" );
})

Thanks cathal, can you talk this out a bit more. I store the content I use to refresh the div in newcontent.html? how do I tag it?

I'm not a programmer so a little hand holding would be appreciated.

What do you mean tag it?

Say you have this in newcontent.html
My Web Design
Just a plain html file - nothing else.

In your main page you would have something like this.
<span class="button-pricing-nav" style="background-color: #fff;">
<a href="#" id="web-design">Web Design</a>
</span>
<div id="mycontent">
</div>

Open in new window


ID in the anchor tag is what we will use to attach a jquery click even to.
ID in the div element is what we will use to target in the jquery

Then you jquery would be this.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script> 
<script>
$(function() {
	$("#web-design").click(function(e){
		e.preventDefault() // Cancel the link default action
		$( "#mycontent" ).load( "newcontent.html" );
	})
})
</script>

Open in new window


Attached is a sample for you to try

Thanks again Cathal. I follow what you're doing and see how it works. One more question. Now what if I have three links, how do I have it pull only the data I need for that click from newcontent.html?

So I have three maybe four options (Web, Branding, Graphic, IT). all the data for each update/refresh in newcontent.html

by tag it I just meant ID which you showed. I'm assuming I need id's in newcontent.html or  use php to pull on the content I need?

Thanks for your help

Just repeat the click code for each element changing the page to load

Or if you want to be a bit fancier

<span class="button-pricing-nav" style="background-color: #fff;">
<a href="#" class="dynamic-url" data-url="webdesign.html">Web Design</a>
</span>
<span class="button-pricing-nav" style="background-color: #fff;">
<a href="#" class="dynamic-url" data-url="Branding.html">Branding</a>
</span>
<div id="mycontent">
</div>

<script>
$(function() {
      $(".dynamic-url").click(function(e){
            e.preventDefault() // Cancel the link default action
            $( "#mycontent" ).load( $(this).data("url") );
      })
})
</script>

this is slick, works really well thanks!

few little nuances i'm now trying to figure out.

1. how do I get the first link/button to be the default option, selected/clicked on page load?
2. how can I set the links/buttons to be active when selected?
3. the content being loaded, between the div tags contains shortcodes, what's the best way to load it. I tried <?php echo do_shortcode('[one_third]'); ?> in a php file, no go.

$(function() {
      $(".dynamic-url:first").click();
      $(".dynamic-url").click(function(e){
            e.preventDefault() // Cancel the link default action
            $( "#mycontent" ).load( $(this).data("url") );
      })
})

You cannot set a link to be active, you can add a class of active to it.
      $(".dynamic-url").click(function(e){
            $(this).addClass("active")
            ...

Cathal,  I wasn't able to make anything work, the code didn't do anything or I used it wrong. i've attached the page code as is it now.  I've also attached some screenshots for the list of items i'm trying to solve.

1. you'll see in image pricing 1 that when the page loads no link is 'active' or the content is not displayed until click. they customer wants the design selected or showing content.
2. then they also want the link showing active, so the white link in the image pricing 2
3. tables work but the code was already done for shortcodes, so if it's possible to load content from a file that has shortcodes in it?

Thanks

You are calling flexslider on an element that doesn't exist - this can break any other jquery.
Remove/uncomment it out and let me know when done since the code seems to be working fine.

Cathal, Well the flexslider is being used so I can't disable it. It's not necessarily being used on this test page but on the main site it is and that is where this content will eventually live. So it needs to work in conjunction with it.

I'm sure this is possible to achieve using this method, I'm just not having success with it. I'm going to award points for all your help, I appreciate it very much. if you think there is something else to try I'm open to it, I'm just not a programmer and this is to the point of frustration.

regards,

You have two copies of jquery being included, one in the head and one in the body
Remove the one in the body.  It's located just before the dynamic URL code
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script><br />
<script>
$(function() {
      $(".dynamic-url:first").click();
      $(".dynamic-url").click(function(e){
            e.preventDefault() // Cancel the link default action
            $( "#load_content" ).load( $(this).data("url") );
      })
})
</script>

Remove it and change the function

jQuery(function() {
      
jQuery(".dynamic-url:first").click();
      
jQuery(".dynamic-url").click(function(e){
            e.preventDefault() // Cancel the link default action
            
jQuery( "#load_content" ).load( 
jQuery(this).data("url") );
      })
})

thanks for the help

<span class="button-pricing-nav"><a href="#" class="dynamic-url" data-url="/wp/wp-content/themes/scrn-child/pricing_test/webdesign.html">Design</a></span><span class="button-pricing-nav"><a href="#" class="dynamic-url" data-url="/wp/wp-content/themes/scrn-child/pricing_test/socialmedia.html">Branding</a></span><span class="button-pricing-nav"><a href="#" class="dynamic-url" data-url="/wp/wp-content/themes/scrn-child/pricing_test/graphicdesign.html">Graphics</a></span>

Don't know what you are trying to do here

<script>
jQuery(function() {</p>
<p>jQuery(".dynamic-url:first").click();</p>
<p>jQuery(".dynamic-url").click(function(e){
            e.preventDefault() // Cancel the link default action</p>
<p>jQuery( "#load_content" ).load( 
jQuery(this).data("url") );
      })
})                                      
</script>

Open in new window


The code should be
<script>
jQuery(function($) {
	$(".dynamic-url:first").click();

	$(".dynamic-url").click(function(e){
		e.preventDefault()
		$( "#load_content" ).load($(this).data("url"));
	})                                      
})
</script>
