I'm writing a form validation function and would like to verify that a field only contains alphanumeric characters. How should I structure that statement? the following seems logical but doesn't work;
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'm trying to make my password field regex-valid, but don't know what to add. Here is my code : $.validator.addMethod("integer", function(value, element) { return !jQuery.validator.methods.required(value, element) || /^d+$/ i.test(value); }, "Numbers only please"); $("#register_form").validate({ rules: { user_password: { minlength: 6, integer:true },}}); But this does not work.
We have been using the following js/regex to find and replace all non-alphanumeric characters apart from - and + outputString = outputString.replace(/[^w|^+|^-]*/g, "");
However it doesn't work entirely - it doesn't replace the ^ and | characters. I can't help but wonder if this is something to do with the ^ and | being used as meta-characters in the regex itself.
I've tried switching to use [W|^+|^-], but that replaces the - and +. I thought that possibly a lookahead assertion may be the answer, but I'm not very sure how to implement them.
Just looking for the simplest. right now my perl script returns an error messge to the user if the date string is invalid. would like to do this before accessing the server.
I am having problems with the code below (obviously) coming up with illegal character for various characters within the field name 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 ....
Is there a way to make one regex to replace a space with " " and a tab with " "?
Currently I'm using two regex's with string.replace( ... ).replace( ... ), but that means it has to run through the string twice. Any way to do what I want in one regex?
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 form and I need to validate a field against three rules:
1) The field need to be between 6 and 12 characters 2) It can only have letters, numbers, and the underscore 3) It cannot contain a space or other special characters
I want the validate to happen in real-time. I have the first rule working great. Here is the code for that:
This has been asked before, and i've seen many of the previous posts. And tried for hours. But finally i've broken and have to ask for help. What am I doing wrong here?
var u=document.forms["lead"]["name"].value; var v=document.forms["lead"]["city"].value; var x=document.forms["lead"]["country"].value; var y=document.forms["lead"]["mobile"].value; var z=document.forms["lead"]["email"].value;
I am doing some basic form validation stuff and I have two fields (phone, fax) that I need to check if the characters enterred are numeric, but still allow + and () characters to be enterred. If anything else has been enterred to display an error message.
Can someone point me to a resource ( I searched, but couldn't find an obvious one!) or give me a rundown on some code here to help me out?
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).
I am unable to solve two problems creating a contacts form using dreamweaver CS3. My other problem is posted under the heading, "Modify code created with Dreamweaver CS3, to compare two text feilds". For this posting, can someone please tell me how to modify my code, pasted below, so that the "First Name" and "Last Name" text fields are restricted to accepting only alphabetical characters.
Here's my current code

I am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code: <script type="text/javascript"> function checkCode() { var x=document.forms["myform"]["code"].value.substring(0, 2); if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'
I have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?

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..

I have character counter for textarea wich counting the characters. Special character needs same place as two normal characters because of 16-bit encoding.
Counter is counting -2 when special character is added like some language specific char.
The .find() method does not seem to match on input fields by using a class. The ti This problem seems to be only visible on input fields. The following is a demonstration of the issue:
