Controlling Character Length Of A TextArea Field
Aug 1, 2007
I have a text area in one of my forms that I want to control the character size of. In short, I want to keep the text area to 10,000 characters.
What I Have Found: I have found a number of scripts that will control the character length of the text area, while you are typing.
The Problem: If you cut and paste a document that contains 15,000 characters into the text area that is limited to 10,000 characters, it will still take all of the information (i.e. the 15,000 characters), as opposed to limiting/cutting it off.
Does anyone know of a script that will control the overall character length whether it be inserted via key stroke or is copy and pasted into the text area? Or possibly point me in the right direction?

I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?

I using the jquery_validate.js script to validate my registration page. Does a great job, but I need to increase the length of password characters from 6 to 8, with at least one number. This is the message a user gets:
HTML Code: Please enter at least 6 characters. I'm quite new to jQuery and I looked at the jQuery validation page and couldn't figure out how to change the parameters. It's suppose to be easy to modified by I'm at a loss as to how to change the rule from 6 to 8 and include a number.

I’m using the following Java Script to set the width of text fields:
<SCRIPT>
if (navigator.appName == 'Netscape') {
document.write('<INPUT type="text" name="textfield" maxlenght="30" class="forms" size=14>
');
} else {
document.write('<INPUT type="text" name="textfield" maxlenght="30" class="forms" size=30>
');
}
</SCRIPT>
How do I use that script to set the width of the text area field below?
<textarea name="textfield2" cols="50" rows="6" class="forms"> </textarea>

I am writing a function to 'expand' common postal address suffixes, such as "RD" to "ROAD", etc.
A suffix must be prefixed by a ' ' (space) character and preceded by either a ' ' (space), '.' (period), ',' (comma), '/n' (line break), OR be at the end of the TEXTAREA box.
Code:
source = source.toUppercase(); // Covert to uppercase
source = source.replace(" AVE.","AVENUE");
source = source.replace(" AVE ","AVENUE");
source = source.replace(" AVE,","AVENUE");
source = source.replace(" AVE[
[Code].....
However, if the text is: "1 Main St" (with nothing after the 'St') the replacement does not work.
Is there an 'end of string' character that I can match on?

There are lots of javascript textarea counters/limiters out there but what I need is a counter that counts and displays the number of characters being typed, the current page number (i.e. say 160 characters make a page), and probably the number of characters left per page. No limit to number of characters typed, just count characters and pages and displays them.

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.

I want to implement a text input box for SMS text messages and the messages are limited to 160 characters (including spaces, etc.). I would like the font color of the text to be green as the user types and any text beyond 160 characters to be red. I would like to do this with one input box, the same box that the user is typing in not a separate display box. This will be on the users local PC it won't be on the Internet.

How do I onBlur prompt the user to enter a ZERO as character one, if one is
not already entered. At the same time, I would like to ensure at least 5t
characters have been entered. This validation should also only trigger if
anything is entered. Basically, if the user chooses to enter nothing then
the check should not be carried out and the user should be able to continue.
So in pseudo style:
If user data IS ENTERED AND DOES NOT contain a ZERO as first character, or
is LESS THAN 5 characters long, prompt for re-entry.
Thanks guys, been trying various things and got close, but have hit a brick
wall.
This ALMOST works:
function checkField()
{if (document.form1.Bsk01.value.length<9) {alert("Please enter a valid code.
The first character should be a zero.")}else if
(/^0.*$/.test(document.form1.Bsk01.value)){return;}else{al ert("Please enter
a valid code. The first character should be a zero.")}}

I'm not a JS expert, but is there any way to detect if there is a certain character at the ending of a sentence in a text input field?
for example, when a user puts "Hello, my name is Gary" into a certain text input with a specific ID and using the JS OnChange event, the script will add a period ( . ) if it is not detected.
or, when a period is detected at the end of the sentence ("Hello, my name is Gary."), it won't do anything.
I got this idea from reading the W3 School onchange doc, but I'm not sure if it's possible.

[URL]...lightweight text editor. I want to be able to submit without a page reload and I can't seem to figure out how to override whatever code the author created to disable the value of the text area field unless the form is formally submitted using the submit button. Additionally I don't seem to be able to attach any events to the submit button. I'm not sure you will be able to help me but thought it's worth a shot. Here's the form:

I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
