I am working on a javascript code for validating phone numbers against 0's.The scenario is that, 1 ) If the phone number contains all 0's in it, an error message is displayed. Eg. 0, 0000, 000-000-0000, 000,0000000000 etc..2 ) Phone number should only take digits [0-9] and some delimiters ()-,.+ "All other alphabets and special characters are not allowed.Eg. 01, 102-125-0214, etc.. ( allowed ) sjjlkjkj, xllfs -09-49- ( not allowed )3 ) The code I have written is as below -

I've been building up my validation using the jquery validation plugin but I can't work out how to get a failed validation to default the focus to the first invalid input rather than to the last selected input. If there is no input field selected, when I submit then a failed validation will focus the cursor on the first field but if the cursor was left in a field and submitted then the focus stays there (if it's invalid) rather than jump to the first invalid input. From what I've read and seen, this is the expected behaviour but not what I want. Is there a way I can get the first invalid field and set the focus to that?

I'm running validation on a form that has two components, a payments segment and an address segment. Both of these need to be within the same form. By default, the address segment is hidden. Upon validation, I would like to display the payment segment, but only if there are validation errors within that segment. Using invalidHandler, I've been able to successfully fire a function when errors are returned, but I haven't found a way to check if there are errors within that container. My plan was to check for the invalid class within that container... something like this:
$(#formname).validate({
invalidHandler : function() {
if ($('.client_validation').length)
$('.billingAddress').addClass('showForm');
}}});
The problem is that the invalid class (.client_validation) isn't applied when the invalidHandler function is executed.

I'm using the datepicker.ui in a form that also uses the validate plugin. The form happens to use the accordion functionality found here, but I've also tested this in a simpler form that uses the standard syntax for both scripts.
When the user initially picks a date using the datepicker, validate runs and flags the input as invalid, even 'though the field isvalid. choosing another date, or choosing the date a second time, sets the field to valid.
Simplified HTML:

which is: S_Gift Finder1_0
I have tried various ways of escaping the characters but to no avail.
I am unable to change the name of the field as it it comes from an external off-the-shelf package. Code ....

I'm using the validation plugin [url]
I must be missing something, is there not an easy way to validate inline?
For example, I have a required text input that is given focus on page load, I would like for it to throw an error if the user moves to the next field w/o entering any data.
Right now, it only checks for errors on 'submit'.

I have a form (form1) to register with the fields: user, email, password being validated normally.
Have a second form (Form2) to the user update the data registered in form1, and the fields user, email, password is already populated with data from the database, the email field I use the remote validation, and as the field already has been completed and read always says that this email already exists, how do I create a rule or method so that when the field is already filled it not do so validating and validate if it is filled with a new email. Email2 have a hidden field in order to do a test type.

I'm working under certain constraints wherein,at a certain point outside my direct control,validate is called with no arguments, but after that I want to set a custom validation function on a form field. I figure there's got to be a way to manipulate validate's internal data structure to add the function, but I don't have a clue as to how.

I have a section of a form containing elements that are not visible, currently just in a hidden div. Some of these elements have validation on them so when the form is submitted it fails on this validation.What I am after is a way to stop the validation firing for any hidden elements. I have tried setting them to 'display: none' and 'visibility: hidden' but this does not have any affect.

If I try to append a PARAM tag twice I'm having problems:
var.medDiv = document.getElementById("myDiv");
var medObj = document.createElement("object");
var p = document.createElement("param");
p.setAttribute("FileName",this.URL);
medObj.appendChild(p);
p = document.createElement("param");
p.setAttribute("AutoStart","false");
medObj.appendChild(p); // <-- this one
medDiv.appendChild(medObj);
The line with the "this one" comment triggers IE to tell me that it has
an invalid argument. If I change the order of the PARAMs then the new
second PARAM will give me the error. If I move the setAttribute to after
the appendChild I still get the error.

Is there anything 'wrong' with setting the value of a drop down menu
using the following?
document.frmStep1.drpInvaddress.value = 'A1020761603!>>R2'
This string is a key in our database that I have no control over and I
want to set the value of the menu according to this value because it
is unique. I suspect that the '' or the '>' or the '!' is making
Javascript think that this is a different type of data than string.
Is there a way to 'force' Javascript to interpret this as string?

I am writing a web site that uses JavaScript to validate certain forms
and I seem to be having some trouble. The site uses PHP and for one of
the forms, depending on the situation, one of of the text inputs does
not exist - the PHP doesn't generate the HTML for it. I wanted to have
the validation script check the length of the input if it exists but I
knew that I might have trouble if I tried to check the value of the
input without first checking that the input exists so I tried using
code similar to this:
if(document.getElementById("someId")!=null &&
document.getElementById("someId").value.length<8)
{
alert("String must be at least 8 characters.");
}
However, when I try that in Firefox (that's the only browser I've tried
so far), the validation script exits, the form is submitted with
errors, and I get a message in the JavaScript console saying that the
ID that I gave was invalid. I know it's invalid! That's why I checked
for null!
I thought that getElementById() would return null if the ID was
invalid. Is there any way to check if the input exists before
validating its value?

I amreceivingthe following error on IE8:Invalid argument. jquery-1.4.2.js, line 5899 character 5 Now I have used the debugger, and this seems to be the only error it catches. And I realize that I could go through each line of what I wrote and figure out what line triggered this portion of jQuery. However in the interest of making jQuery better, I want to understand this error and fix it in the jQuery file.

I am currently writing code to populate a select tag with all the hours of the day. I recently rewrote a function that will populate a temporary select tag based off a time passed in as an argument and then return the temporary select at the end. When I attempt to assign the product to a variable, Javascript gives the error "Invalid Assignment on left-hand side." Have I stumbled onto one of the cases where you can't directly assign variables to each other, or is this a syntax error?
This the line that is giving me an error
eval(select1) = newHours('000');
Where select1 is a variable that contains the name of the day and a number, both of which change depending on input, hence the eval statement. The function newHours returns a temporary select.

I'm trying to duplicate some PHP code in JS, but keep running into "invalid quantifier" errors for regular expressions.Here's an example of what I'm working with:
Code JavaScript:
var elementId = 'ipaddress';
var regexsplice_IP_ADDRESS = '(?:[0-9]{1,3}.[0-9]{1,3}+.[0-9]{1,3}+.[0-9]{1,3}+)';
if(!RegExp(regexsplice_IP_ADDRESS).test(elementId.value))){
[code].....
1) do I need to double up on the backslashes within a string using single quotes on characters that are seen as escape characters in regex, but not javascript?
2) do I need to start and end the string with a special character, like I would with preg_match in PHP?
3) To use the RegExp() function to prepare a regular express created from a string...can I use it like in the example above? Or do I have to use a separate delcaration like: var theregex = new RexExp(regexsplice_IP_ADDRESS);
