Question

So there are a few things I want to do. I have a section of HTML that I would like to be displayed on the page by default (i.e. the first time it loads).

<div class="viewport">
        <ul class="overview">           
            <li><img src="images/1.png" /></li>
            <li><img src="images/2.png" /></li>
            <li><img src="images/3.png" /></li>         
            <li><img src="images/4.png" /></li>
            <li><img src="images/5.png" /></li>
            <li><img src="images/6.png" /></li>
            <li><img src="images/7.png" /></li>         
        </ul>
    </div>

However, upon clicking an icon I would like for this section to be reloaded as a snippet of javascript is updated.

The code for the icon is:

<a href="#"><img src="images/2.png" id="icon#2"></a> | 
<a href="#"><img src="images/3.png" id="icon#3"></a> | 
<a href="#"><img src="images/4.png" id="icon#4"></a> | 

The JS snippet that is updated is:

var win_width = $(window).width();
var num_of_images = 2; // This should be changed to 3, when 3 is clicked, and 4 when 4 is clicked, etc.

So it should reload the ‘viewport’ div on the page only…not the entire page.

Thoughts?

Answer 1

    $(function () {

        var num_of_images = 2,
            showAndHide;

        $("img[id^=icon]").bind("click", function () {
            num_of_images = parseInt(this.id.replace("icon#", ''), 10);
            showAndHide(num_of_images);
        });

        (showAndHide = function (n) {
            $("ul.overview").hide() // hide this while we "do work"
               .children() // get children
                  .show() // show all children
                  .filter(":nth-child(" + n + ") ~ li") // get the next siblings of the nth child
                     .hide() // hide them
                  .end()
               .end()
            .show(); // show the parent list
        })(num_of_images)

    });

This is a “pending” solution. I have not tested this and I would be surprised if it works.

EDIT: Alright, I tested and fixed a few things and this seems to work.

Note that I attached a click handler to those img elements. So you don’t need those anchor tags if you don’t want them.
