JQuery :: Simple Fading DIV Test Not Working - Anchor Tag Null?
Sep 8, 2009
I'm doing some simple tests and I can't get this to work on a wordpress site. Basically I'm trying to fadeOut a div with id of "box" when a link is clicked. I mentioned Wordpress because the head code is loaded dynamically into the page template, as well as the body content. I wasn't sure I this made a difference in diagnosing the problem. When I load the page, Firebug keeps giving an error...
$('a') is null
Here is my stripped html code...
<head>
<script src="[URL]"
type="text/javascript"></script>
<style type="text/css">
#box {background-color: red; width: 300px; height: 300px;}
</style>
<script type="text/javascript">
$(function() {
$('a').click(function() {
$('#box').fadeOut();
});
});
</script>
</head>
<body>
<div id="box">
</div>
<a href="#">Fade Out</a>
</body>
've got a fairly simple slideshow object which takes an array of images and rotates through them, with a fade between each picture. But it seems to use a fair amount of cpu, especially on IE, a little less so on firefox. Any ideas on how to optimise this? I'm concerned that the way the object refers to itself may not be the most efficient.
Code: function picSlideShow(elementID, picArray) { var self=this; this.id = elementID; this.picArray = picArray;
When looping thru a group of elements and using getNamedItem('itemname').value there are some elements that are going to have a null value for that particular getNamedItem... the problem is that you cannot test this value to see if it's null because it generates an error instead, and the code does not continue: _allnames[_j].attributes.getNamedItem("onchange") is null
You cannot even test it for null like this: if (_allnames[_j].attributes.getNamedItem("onchange").value != null) { do something } This will also generate an Error instead of testing to see if it is null.
How do you test getNamedItem for null to avoid this error?
EDIT: It appears that the problem is limited to Firefox. It works fine in IE7, but the error occurs in both FF v3.5.4 and in v3.5.5!
In my example below, there are no elements that match, so you should see an alert box that says 'No match', but (using Firebug) you will see that an error is generated when it tries to find the value of onchange in the last input tag.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta http-equiv="content-type" content="text/html; charset=windows-1250">
is there a function that get the name of the first input field of the current form ?
in my example below I want create an array of form field name and in the onsubmit assign all element's name to create a simple iteration to test if some elements in my array, that must be required, are null:
something like function verify(array of string)and in onsubmit something like return onsubmit(field1,field2,field3....) Code:
I have a JQuery script that gives a neat effect on the navigation and want to include a simple fading slideshow on the same page.Any script I have tried for the slideshow either uses JQuery or Mootools and it conflicts with the navigation script.Can anyone recommend a smooth fading slideshow that wouldn't conflict or suggest how I can get around this. I read a bit about 'no conflict' but don't understand how to implement it.
When using the code below the alert returns a value of null. In the past this has never happened, it has always returned the xml file I'm requesting. I have noticed a strange difference between browsers. This script is used to fill a form automatically. In its current state it works perfectly in opera, but does not work in firefox or IE (used to work in all the browsers). I'm by no means a javascript expert, am I missing something here?
I have written the below script to swap images in a main viewer for a gallery on a website (I apologise if the script is not very elegant I have only just started learning JS).The idea is there are 2 divs one positioned on top of the other, when the user clicks on one of the thumbnail images the div on the bottom changes to the new image, then the top div fades to transparent to reveal the new image, then once the top div is completely transparent it's image is swapped for the new image and it is made opaque again.Anyway elegant or not the script works fine in Firefox, Safari, Camino and (shockingly) IE, but it doesn't work at all in Chrome.
Code: var fadeTime = 800; var newImage; var images = new Array();[code]....
So I am creating a page with unordered lists housing a large range of numbers. I want to dynamically create anchor tags and write them in before each UL. In FireFox it works just fine, however; in IE7 the anchor tags won't work.
I loaded the jquery ajax file in Div id:main_content, but in another div id:List <a> tag is not working. Both Div i loaded the the content as ul,li format.
When I load the page the div #forgot_login blindes down even though I did NOT click the anchor link. Also, clicking the anchor link does not toggle it up and down. The event binding is not working.
HTML <a href="#" id="forgot_login_link" title="Show">Show</a>
It worked fine as long as the href attribute of the anchor tag was '#'. Then I tried using href other than '#' and ran into a problem. I just changed the href to:
I am very new to javascript and have only just started looking into it after working quite a bit in html, css and php.I have a working image banner on my webpage that switches between 1 of 2 images every 7 seconds. This all works fine but i now need to make the second image 'pcm2.jpg' a clickable link where as the first image 'pcm.jpg' which starts off the image rotation in the html page has no link. I have tried using 'document. rollbanner.href =' inside the function but that hasn't helped. Is that because the first image in the html page has no href value to begin with? If so how do i get around this as i dont want the first image to have a link, only the second one.
I'm using the standard module pattern and the problem is once you set a private variable, trying to test that object independently becomes a nightmare as the next test is polluted by the actions of the previous.So, the options are to have some reset method (which is horrible), setters on everything (defeats the point) or delete object and re-load script (hideous).
[URL]This is my website and you can see the images in the header are messed upbecause I tried to use "jcarousel" but it is not working and I have to sort this out
Heres the code for sub-account-ajax.php: <?php if (isset($_POST['email_address'])){ echo 'youre set'; }else{ echo 'nothing set'; }?>
When this code is executed I do not get any alerts or any error messages whatsoever. I've been pretty good with figuring things out so far with jQuery, but this is the first I'm stumped with.
I need to get the page to reload with the anchor in the link when it is clicked in a dropdown menu. For example if I am on 'www.domain.com/about/#2' and I then click on 'www.domain.com/about/#3' the url changes but the page doesn't reload so I need the page to reload, but keep the new anchor (#3).I gave the links with anchors a class of 'reload' and tried this:

I am trying to autofill a box by clicking a link (with return false). The function to autofill works with button tag but not in anchor tag - instead of returning false, the click event transitions to the href.
