Javascript Toggling
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>开发者_运维问答;<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
- All div's are shown
- Clicking on a td for a date will hide all but the div with the class of the day clicked
- clicking "All dates" will show everything again
any idea how i could achive this cleanly? ideally using JQuery.
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
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>
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();
}
});
});
});
