I do not know javascript but I just wanted to check to see if this is valid javascript across all browsers that support js.
<script type="text/javascript">
function locate(page)
{
thePage='http://www.domain.net/' +page
window.location=thePage
}
</script>
<a href="#" onclick="locate('page.php'); return false;">Send</a>
It works in IE, should I expect any problems in any other browser?
I'm considering in teaching myself some javascript, but before I take the time to read up and experiment, I had a few questions.
Is javascript XHTML 1.0 STRICT Valid?
Is javascript valid for any version of XHTML?
Is javascript easily cross browser compatiable, or will this take a long time to work around?
How do I verify that a given URL exist before actually loding it using
javascript?
Is the window.status still useful nowadays or is it outdated? If it is still used, why doesn't this work?
<a href="javascript_status_bar_messages.cfm"
onMouseover="JavaScript:window.status='Status Bar Message goes here'; return true"
onMouseout="JavaScript:window.status=''; return true">Hover over me!</a>

Say I have three variables: month, year and day. How do I check whether they form a valid date, i.e. not "Februrary 31 1999"?
View 5 Replies View RelatedI've been doing a bit of research and haven't found anything too easy. Can anyone point me to an article that has a function written in javascript that validates that a date that has been submitted via a form that it is a valid date?
View 4 Replies View RelatedI am building a custom validator. I don't want any suggestions on using a jQuery framework, i just want to ask a few question on how best to continue.
Code:
<script type="text/javascript">
//Validator Strings And Expressions.
var Letters = /^[A-Za-z]+$/;
[Code].....
This is the "on page" validation. This, as you can see calls functions held in an included file onkeyup. This all works well, also the username check ajax call works great. However I have 2 questions that I need to sort before this will work correctly.
1. Using M_USERNAME form as an example. If I start typing in there it will begin validating, which is great, However, if i typed in "matt_thomas" based on the validations, Empty:Pass, ValidChars:Fail, Range:Pass, Check:Pass.
So I know that it isn't empty, it's the correct length and it's not already in the DB. But it fails because of the "_". This should mean that I receive the error i have setup for that failure. But I don't. Because I don't stop on a Fail, I receive the success message of the last function.
So my question is; How Can I stop running any more functions when one fails?
2. Looking at the above code, How can I make sure that a submit will only work when ALL fields validate correctly?
Where can I find a list of valid names for Navigator.AppName?

The following script generates three SELECT menu's... one for days one for months and one for years. Each time a new year or a month is selected the menu's are updated to allow only valid dates. Its only just been finished and could probably use commenting more, but im always open to suggestions, advice and criticism.
View 19 Replies View RelatedI try to make a script which check's input's value every time when value changes. There must be ready example somewhere, but I just could not found it. The value shoud be hex-color-value (like #FFFFFF), so script should check if the first character is # and after that only characters a-f, A-F and 0-9 are ok. I guess it goes something like this:
function checkHex(value) {
// if value string includes only characters # a-f A-F 0-9 value is ok
// else value is not ok
}
<input type="text" id="hex_input" onkeyup="checkHex(this)" />

Also, which version of javascript (1.2 ?) is needed for same?
I have an online shopping cart and some of the products are sold in boxes of 6. So I am trying to write some code that will alert the customer if they have entered a quantity that isn't some multiple of six.
I've tried using the modulus operator as well as dividing by 6 and then checking to see if the result is a whole number but inevitably the alert box pops up no matter what I enter.
This is what I'm trying to use now:
Is there a better way to check if the entered quantity is a multiple of 6?
I was hoping that someone could give me a hand with a regex quetsion. I'm quite new to it all, but managed to get things working pretty much how I would like them except for allowing special characters such etc.

I have a signup form that the user fills out. Among other textboxes, there is an Email textbox, and a Password textbox. These are the two I want to do some Ajax work on.
Right now I'm choosing to go the onblur approach, but is there something better? I'd really like Ajax to go into affect when the user has stopped typing. I know there is key up and key down, but that won't really be too good for what I'm doing. Besides that though, this isn't the real problem.
My problem is this, when the onblur function is called, I want it to return text to a specific element on my HTML page depending on if the fields are valid or not.
Here's the part of my HTML page:
<div id="signuperrorsection">
<span class="error"></span>
<span class="valid"></span>
</div>
Anyway, if the email address for example is valid, I want the valid class to get the response. If it's invalid I want the error class to get the response.
Here's my javascript (right now I'm only trying to implement the Email field):
function checkErrors(str)
{
if (str=="")
{
[Code]....
Now the way I have this set up now, both classes are going to get the text, correct? Well I of course don't want that. I don't know how to have it set up so that only one class gets the response depending on what the result is.
I'm not sure how to do this because I added a js function to run on a form's submit button's click event. The js function does run, but then no matter what, the php script is called. The alert runs, then it goes to the php script. How can I stop it doing it?
here is js function:
Code JavaScript:
function checkFields(form){
var myForm= document.getElementById(form)

I am trying to make a link dead until all fields are valid. Once they are validated and match the regex, the link should take you to its destination.
[Code]...
As of now, you can click the link and a lightbox will show up displaying verify.php no matter what the case; even if the fields are considered invalid values by regex. I want the link button (#various2) to be dead until all text fields match the regex assigned to them.
ALSO, for some weird reason, my link has to be pressed twice until it is able to recognize the urlstring in the js. So....when the viewer comes to my site, they will press the link once (nothing happens) and have to press it again for it to work.
I was wondering if the following would be a valid JavaScript
assignment vor a variable and if anybody knows this to work in IE6 or
lower?
var someVar = (typeof(someVar) === Object) ? this : getVar();
function getVar(){
alert('getVar() called');
return(true);
}
alert(someVar);
alert(someVar);
