Mozilla-based browsers have watch and unwatch methods to detect change
in value of form elements (or any Javascript variables really). IE
doesn't support this.
Is there a a reliable cross-browser way alternative to this? Something
that will let me detect a change in value for a form element and
trigger my own callback function upon change?
Hopefully, something that is generic enough to be called as
"MyWatch(element)"!
I have a Joomla website which are using VirtueMart. I want to watch the submit of a product (which is using AJAX) and when the request is succesful and complete then send a new XHR request to upload another part of the website.How do you think I should do with Mootools?I first success to do it but only by adding an event on the form submit. So when I click on the Add to Cart button, it is working but I would like to wait until the first request is complete.

I'm trying to style a fugly advertisement that pops in on my page. Right now I have a standard setTimeout going, but it could take 2 seconds, or 5 seconds after document.ready triggers :/
Is there a way to somehow put an event on a div to watch for an ID to appear perhaps?
I am building a simple timer. It works ok, but doesn't do everything it is suppose to do. When pos1 reaches 1, it is suppose to reset the timer and display an alert message saying that it has reached the maximum time. It does that just fine but after it resets, it starts over automatically and I don't know why[code]
View 1 Replies View RelatedI'm trying to add watch() to IE, and have more or less working code:[code]That works until I try to use setInterval with the code in red color. I never really tried OOP or prototyping in JS, so my whole approach to the problem might be wrong, but anyway, I think that if I execute that code in red every 100ms [for example], I'll be able to catch changes to properties on which the method is registered. Well, either my idea is wrong, or the execution.Some parts are commented out and method name is changed so that I could work in peace in FF.

Is there any way we can watch variable values inside javascript functions while running through the debugger. I am using javascript along with ASP.net on Visual studio 2010.
View 2 Replies View RelatedI have a javascript program that works fine under Firefox and on IE
when running XP, but is having a problem with IE running under Windows

On my personal XP development machine I have the Microsoft Script
Editor and I can set a breakpoint, step through code, inspect

On a machine where I am trying to debug this problem I am running

However, from what I can tell, there isn't anywhere to inspect or watch

I'm having some problems understanding the append() function. What I'd like to do is select an element using it's ID and add a row to the table with a HTML form element. The table is dynamically generated using a Django template ( form.as_table() ) so I'm not able to alter the original HTML markup too much.

I have created a form with malsup's Form Plugin wherein it submits on change of the inputs. I have set up my jQuery script to index drop down menus and visible inputs, and uses that index to determine whether keydown of tab should move focus to the next element or the first element, and likewise with shift+tab keydown. However, instead of moving focus to the first element from the last element on tab keydown like I would like it to, it moves focus to the second element. How can I change it to cycle focus to the actual first and last elements? Here is a live link to my form: [URL]. Here is my script:

var errorDiv = document.createElement('div');
errorDiv.setAttribute('class', 'confBox');

I tried jQuery('#calculateform').children('input, select, textarea').each(function(key){ alert(key + ': ' + jQuery(this).val()); but it goes only 2time throw (for each button it has)and it SOULD list all elemts (including hidden fields). I need each element with name and value.
View 3 Replies View RelatedHow does one cause a form element to appear ONLY if a certain form selection is made before it?
That is for example say there is a form element of type Radio called "format" so only if they select format value = normal then the form input fields called URL and Name are to appear as the next choices otherwise form input field Group and checklist Places are to appear as the next choices.
I'm working on a script that will produce multiple dynamic forms based on the results of an ajax request. The ajax request does a db query that will return 0 to x number of rows. For each row, a new serialized form is created. Since the forms do not exist at page load, I'm having problems getting the value of the form elements so that I can run other functions on them (update inputs and selects). I've stripped down everything so that I can show a basic example. In the example, how would I get the value of "#orderID"? The body contains a div (previousList) that has a list of items that when clicked will trigger the ajax query. It also has a div (line details) that will hold all of the forms that are generated.
<div id="lineDetails">
check it out </div>
<div id="previousFrm" class="ui-widget-header ui-state-highlight ui-corner-all">
<h3>Previous Returns/Cancels</h3>
<div id="previousList">
<ul class="previous" id="returnList">
<li id="1000997" class="names">1000997: 101853</li>
<li id="1000995" class="names">1000995: 101853</li> .....
But callingconsole.log("order line value is " + $("#orderID").val());
results in 'undefined'.
I would like to have an element, a text string, change into a select
when a mouseover occurs and then change back to text when a selection is
made or when a mouse out occurs. I looked a t using dojo for this,
http://dojotoolkit.org, but this will end up on a production server,
where dojo is not installed and cannot be installed. So, I need another
solution. Can someone give some pointers on how this might be done?
I'd like to set up a bit of javascript to be run when other javascript
loads a new page via something like { top.window.location.href =
newLocation }, and have access to the new value. (For example, so that
the target URL can be modified before fetching.)
In Mozilla, top.location.watch("href",fn) works well for this purpose.
In IE, neither watch() nor an onpropertychange handler set on
top.window.location work.

View 1 Replies View RelatedI've been struggling trying to get a small order form to work the way I want it to. Here is a link to the live page: [URL] And here is the code in question:
[Code]...
I have two questions...
Question 1 How can I make this piece of script act a little smarter. Look at the order form, I'm catering for up to 4 people and providing lunch for them. If they select 3 people and the spaghetti bol for lunch, it's only adding $10 where it should be adding $30. Obviously this is simple multiplication but since the values in my form are prices it makes it a little tricky. I'm guessing an onselect on the first part of the form which changes the pricing of the other items would be the way to go, but how do I do this?
Question 2 The "Total Price" is placed before the <form> tag by the script. This is ok but it's not where I want it. How can I position this text elsewhere in the document?
I am trying to change an attribute of an element but can't figure out what the selector is to select it.
the page code is like this
<div class="slideshow" id="slideshow"><span class="image-wrapper current" style="opacity: 1;"><a title="" href="#2" rel="history" class="advance-link"> <img alt="" src="images/samples/1.jpg"></a></span></div>
I want to add a top css attribute to the img tag.
I tried many things such as
$('.advance-link:first')
$('.advance-link:firstChild')
but none seem to be working. The img gets generated by another script so I can't add an id or class to it. I figured an expert at selectors would be able to explain how to select it.
I am trying to add some styling to the first word of all of my H2 headings.
Now obviously this would be very easy to do using a span, but let me clarify my situation.
I am working on a Joomla! site, so a lot of my code is read from php and sql files. I thus can't go and wrap my text in a span by hard coding it since it is dynamic and read from a database.
I thus decided that manipulating it using javascript will be the simplest. The only other chice is to write a php script that does pretty much the same thing, but I prefer javascript.
So here is what I am thinking of doing:
I want to select all of the H2 elements from my document, get access to their text content, single out the first word, and then wrap it in a span. The span will have a class, which will then simply be styled using CSS.
I though I was on a roll, but is seems that I have hit a snag. I am able to select and edit a single element with an id, but not all of the H2 elements in my document.
I was using 'getElementById' and assumed I could simply change it to 'selectElementByTagName' at some point.
I then used 'innerHTML' to retrieve and manipulate the contents.
Here is my code so far, and it work to some extent:
Code:
It seems though that 'innerHTML' does not work with 'selectElementByTagName', and I can't seem to find a similar command that does.
I also can't use ID's since I can't manipulate the HTML (at least not without scratching through a whole mess of php). Even then I need to manipulate various elements on one page, so ID's are no good anyway.
So my question finally is this: Is there a similar command I could use, or am I busy going in the wrong direction?
