i am trying to check a character with another character which are in the same text box.when we are entering date,date in the first text box and month in another text box and year in another text box.now i want when i am trying to enter '0'in the character position when there is '0' at first character position it must raise an alert box as well as when i am trying to enter a digit greater than '1' at 2nd character position it must raise an alert box when there is '3' in the first character position.
I would like to write a parser like the one below except I would like it to take characters with the the digits like 345j, 982p0, what would I change to be able to have characters with numbers?

Awhile back I posted a script that was working fine in IE but not in Firefox. This is again my dillema with another piece of code.It is supposed to limit the number of characters accepted by a textbox.Here's the JS:
<script type="text/javascript"> function textCounter(field,cntfield,maxlimit) { // if too long...trim it!
i don't know how to check for illegal characters for name.. i have one for username but i don't understand how to use it.. it does not allow spaces so it will not work for first and last names..
am doing a check on my fields, so that they only contain certain characters and numbers. var validEntry = /^[a-zA-Z0-9@$&"]+/; but this also captures a space in between words as an error. can somebody please tell me on how to avoid this.
Ive got a project and ive been steaming ahead with it myself for a bit, i was given the code to start off with but have adapted it for my own needs. As well as fieldOne being a minimum of 3 characters I also need to check if the first three characters are the same because we get a lot of spam.
So I want to be able to check the last 15 characters of a string for either <br /> or a space. I know how to do this with PHP but I have no clue how to do this with Javascript and Google is failing me. Could someone point me in the right direction?
Example string: var string = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat."
I'm assuming this will be done with lastIndexOf but I do not know how to do it. So to reiterate, I want to check to see if either a space exists, or <br />, delete everything after that, and return the string. So the output of the example string would be...
Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo
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 am trying to check for Arabic characters in a string using Regular expressions. This should return true, as the string in the str variable is indeed Arabic character. But it returns false.
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 am pulling a value via JavaScript from a textbox.If the textbox is empty, it returns NaN.I want to return an empty string if it's null, empty,etc.What check do I do?if(NAN = tb.value) ?
I need to validate three textboxes and it will validate for numbers. How should I change my code to validate three textboxes?
Code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
[code]....
I need to use Javascript to validate 3 textboxes, whereby the users can only key in numbers (because they are phone numbers related fields). If any of the textbox is empty, display an alert message to show which textbox is empty. I do not want to show many alert messages to show that, for example, text1 and text2 are empty, it will show two alert messages. I would need to show one "summarized" alert message instead.Next, check if the textbox matches the pattern (which is to check if it has the skeleton of a phone number). If it is, show an alert message that it is alright. Else, show that it does not match.
What I want to do is to check if the selected date in a form textbox is less than today in which case an error message should be displayed. I tried to write the code myself, but unfortunatelly I miss something.Here are th lines:
Code: function dateValidation() { var obj = book.dc1.value; var day = obj.value.split("/")[0]; var month = obj.value.split("/")[1];
