Question

I'm trying to get a toggle effect but not quite sure how to do it or what to look for. (i jave Jquery loaded).

assume html similar to

<table class="left-dates">
    <tr><td>All Dates</td></tr>
    <tr><td>01 dec 2009</td></tr>
    <tr><td>02 dec 2009</td></tr>   
    <tr><td>03 dec 2009</td></tr>   
    <tr><td>04 dec 2009</td></tr>   
</table>

<div class="box 01-dec-2009">
    foo
</div>

<div class="box 03-dec 2009">
    bar
</div>

<div class="box 04-dec-2009">
    foobar
</div>

Steps to take

  1. All div's are shown
  2. Clicking on a td for a date will hide all but the div with the class of the day clicked
  3. clicking "All dates" will show everything again

any idea how i could achive this cleanly? ideally using JQuery.

Was it helpful?

Solution

Here is a working example with jQuery.

Note that I had to change your div classes and td labels to remove whitespace so that the labels would be equivalent to the class-names. If you didn't want dashes in the labels you could do string manipulation in Javascript to remove white-space or give the tds the same classname as their corresponding div and then look at the classname of the clicked td rather than its inner-text.

<html>
<head>
    <title>jQuery hiding example</title>

    <script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js'></script>

    <script type='text/javascript'>
        $(document).ready(function(){
            $('td').click(function() {
                var target = $(this).text();
                if (target == 'All Dates') {
                    $('div.box').show();
                } else {
                    $('div.box').hide();
                    $('div.' + target).show();
                }
            });
        });
    </script>
</head>
<body>
    <table class="left-dates">
        <tr><td>All Dates</td></tr>
        <tr><td>01-dec-2009</td></tr>
        <tr><td>02-dec-2009</td></tr>       
        <tr><td>03-dec-2009</td></tr>       
        <tr><td>04-dec-2009</td></tr>       
    </table>

    <div class="box 01-dec-2009">
        foo
    </div>

    <div class="box 03-dec-2009">
        bar
    </div>

    <div class="box 04-dec-2009">
        foobar
    </div>
</body>
</html>

OTHER TIPS

I would try it this way:

var $boxes = $('div.box');

$('.left-dates td:gt(0)').click(function(e){
   var class = this.innerHTML.replace(/ /g, '-'); // Convert text to class
   $boxes.filter(':visible').not('.' + class).hide(); // All visible div.box that don't have the class we are going to show.
   $boxes.filter('.' + class).show(); // Show this class
});
$('.left-dates td:first').click(function(e){
   $boxes.show();
});

EDIT: I swapped .click() in for .live('click'). If there were going to be a ton of rows, it might be better to use .live() instead of binding a click() event to each td

Also, the HTML you posted has an error. The 03 div is missing a hyphen before the 2009

Identify your <td>All Dates</td> uniquely. Assign the same class or some other identifier to all your date <td>s. Give them a click handler that hides all the .box elements except the one with the same date. In your example you're not consistent with making the date in the <td> the same as the class name of the date in your divs, which you'll need for what I'll do.

<table class="left-dates">
    <tr><td id="alldates">All Dates</td></tr>
    <tr><td id="date">01 dec 2009</td></tr>
    <tr><td id="date">02 dec 2009</td></tr>       
    <tr><td id="date">03 dec 2009</td></tr>       
    <tr><td id="date">04 dec 2009</td></tr>       
</table>

// unhide all box elements
$("#alldates").click(function(e){ $(".box").show(); });

// For each date <td> element
$("#date").each(function(){
   // assign a click event
   $(this).click(function(e){
      // when the user clicks, get the
      // <td>'s text contents
      var myval = $(this).text();
      // and grab each element with the
      // 'box' css class
      $(".box").each(function(){
         // for each of these 'box' elements,
         // if it has a class matching the date
         // they selected, return
         if($(this).has(myval))
         {
            return;
         }
         else
         {
            // otherwise, hide itself
            $(this).hide();
         }
      });
   });
});
