I know this is probably a really simple this to do, but for the life of me I can't figure it out. I want to find out the value of a style for a certain element. So say in the CSS I said 'content' had a width of 100px, but I want to get that value with Javascript.
Here's my shot at it:
alert(document.getElementById('content').style.width);
I just get null.
My understanding had been that $.css("width") would return the original user selected style, eg "100%" or "10em", and $.width() returned the computed width, always in "px". Not so, following the code through for .css(), it calls something called getComputedStyle and the only difference between the two functions turns out to be a post-fix of "px" on the .css() result - not very useful. I need to know whether my user has called me with a proportional dimension, or a fixed one. How to tell with jQuery?
View 1 Replies View RelatedI have built a website and I wish to hide my code between "style type="text/css">....</style>
Is there a way to hide the code between it?
This is probably quite a simple problem but I can't figure out the answer. I'm working on a site that has news stories and events coming in. What I would like is to have the news stories to be styled with squares and events with discs for instance. I might be able to change the actual plug-in so the CSS affects this change, but I just wondered how I could change the list-style-type with jQuery.

if I have an html page that uses the <style> or a <link> to call a style sheet these properties aren't available to JavaScript is there a good way to access them? eg
<html>
<head>
<title>expandable text area</title>
<style type="text/css">
[Code]....
here's what we have in an html file.
<form .....
<input type=button name="comment" onclick=" prompt('enter comment','
' )" >
Is there anyway to get the value returned from the prompt in the statement
above, into the value of the statement below ?
<input type=hidden name="comment_text" value = ???? >
We would like the user to click the "comment" button, have another window
popup where they enter their comment, and then take the comment text and
append it to the value parameter of the hidden statement.
The following code is supposed to return a variable containing text, currently the code posts the data but returns an "undefined" variable. Can someone tell me what's wrong? code...

View 2 Replies View RelatedI'm not overly proficient at Javascript, but have fumbled my way through some tutorials to come up with the following code to create a tab mechanism.
It works perfectly in Firefox, Safari, Chrome and IE8. However, in IE6 and IE7 it fails to operate as of the 'for (var i in temp) {' line. It doesn't error out, it just doesn't perform any of the functions within the for.
Some things I've noted: * In Firefox if I alert(i) below the for, then it alerts the numerical value of i correctly through the for loop. * In IE7, however, alert(i) alerts the value 'toJSON' and nothing more. It never finds 'if (i <= maxlen) {' to be true as a result.
Any thoughts on what's going wrong here?

I'm using Jquery to return the value of an input box based on the ID of that input box but can't seem to get the syntax to work.
Code JavaScript:
var partNo = $('.quantity input').attr('id');
var quantity = parseInt($('.quantity input id').val());
I would like to document.write the status value using the return function but I can't get it to work.
The output should be Markers On or Markers Off.

View 1 Replies View RelatedNone of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code:
<code>
<html>
<head>
<title>This is a test of getElementById</title>
</head>
<body>
<div id="area" name="area_name">xxx</div>
<script type="text/javascript">
var divs = document.getElementsByTagName('div');
var msg = '';
msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "
";
msg +='Test area width by id = ' + document.getElementById('area').width + "
";
msg +='Test area width by name = ' + document.getElementsByName('area_name').width;
alert(msg);

I've created a script that should display a certain image based on the day of the week and the time of the day. After uploading the page to the site I receive no errors, however I'm not getting the display I should be seeing. It always returns the image from the final "else" statement. I'm thinking the problem is that I have two "&&" operators in each "if" statement, and I don't have the proper syntax, or perhaps I'm not writing it properly. Code:
View 4 Replies View RelatedNeed some help with my For loop. The issue is that, my loop is only returning the values of the last item in the js file. I want the select box to include all possible names.
Code:
This function was working in Safari but not in Firefox. I was referencing a couple of elements using the forms[] array instead of getElementById(). I changed those refernces to use getElementById() and now the calculateTotals function does not work in Safari or Firefox.
So I did an alert box to see ucell and it was null. I tried two more alert boxes for the id I was passing to getElementById and for the id of the actual element on the page (which was also created dynamically). They were both identical. The element is created in the onload event, and I am not calling the calculateTotals function until there is onchange event on a text box. So it is not that the element has not been created yet. .

Is there any way of returning all the fields in a layer?
I got a bunch of input fields grouped in different layers inside a form. When someone changes something in one input field in that LAYER, I want it to validate the whole layer, but not the whole form.
Is there anyway of returning all the input fields in that layer as a collection perhaps?
So for whatever reason the convertToArray function in the following code returns false if the argument is more than 1 character long. If it's 1 character long it just returns the character as an array with only one value.What I'm trying to do is take a string of numbers, plus signs, and minus signs and convert it to an array.

(well it's returning "0" not the value I should be getting) I'm asking it to find the number of links on my simple html page.

I have a script for creating 3 dependent dropdown menu.
Selection A in 1st drop Down returns
Selection B in 2nd drop Down which returns

To C I would like to attach a string of 3 value (prices). I was thinking of using the array

Currently, I'm building a website with jQuery. The function below helps me to get content from a database. In the file content_ajax.php there are some functions to handle ajax-requests. JS calls the PHP-function correctly (I've send an email to myself inside that function to check) but the script doesn't return 'succes' and doesn't give me an error...Also, when I put an alert inside the succes and error function, it doesn't popup!
What may be relevant: - site uses mod_rewrite for friendly url's
I have this basic code following and its not returning anything at all. Even the alert is not alerting. I have checked and the select is sending the value fine But nothing happens on return. What i am missing?
$(function() {
I have a bunch of divs with the same classname, 'mediafield':
And I have this jquery code in my header:
So I know that the click function is getting implemented.. The alert box appears however I get the following error in firebug: uncaught exception: Syntax error, unrecognized expression:[@class=mediafield] Line 0
Nothing happens when firebug is turned off... So I'm not sure why it's throwing the error.
I'm working on a small project and want to create a simple dialog window. I know I can use a plug-in, however that is a bit of a over kill plus its a good way to learn more about jquery.
So everything was going well until clicking the button. I cannot find a way to return the value of what button was pressed so I can take further action within the function.
