Do Not Allow Certain Characters In Text Box?

Oct 4, 2010

I have this code that only allows a period and numbers to be put in the text box. The problem is that the message also appears if the text box is left blank. I don't want the error to appear if the text box is left blank. Right now I have it on a Blur so that the error message appears when the person clicks outside of the text box.

<script language=javascript>
function checkNumeric(value)
{
var anum=/(^d+$)|(^d+.d+$)/

Limiting Characters In A Text Box

Jul 23, 2005

I have a input filed of type "textbox" into which I am expecting to get
currency values (ie. 199.99). Is there a way that I can restrict the
user to only entering 2 values after the decimal point?

I can restrict the maxlength to 5, but that wouldn't stop the user from
type in 1.987.

Minimum Characters In Text Area?

May 16, 2011

I have two text areas. I would like to prevent form submitting if the member does not enter at least 100 characters in each text area. There is no maximum number of characters, just the minimum (100 characters).

In case that he hit submit button I would like to display him a message that would inform him that he didn't enter minimum requested characters.

It would be neat if I could have the character counter below of each text area which should be decreased with each entered character.

JQuery :: Prevent User From Adding More Characters Into A Text?

Jul 2, 2009

is there a way to prevent user from adding more characters into a text input based on a validation rule(eg. you entered more than n words, you can't enter more, but you can delete or edit)? I think I'll have to programmatically delete the extra letter(s) that user just input somehow if the addition causes a violation of the rule, is this the best way?

Convert 2 Characters - 2 Text Areas (input And Output) + "convert" Button

Aug 2, 2010

I would like to create a program which converts some letters into different ones.

1) I want 2 text areas (input and output) + "convert" button

2) if I type in the input area the letters "ea" I would like it to be converted into "a", so that If I type "cambrea" and press "submit" the output text will have "cambra".

3) if I type "e " which is (e+space) I want it to be converted into " " which is "space" example: if I type the word "spine " it should be converted into "spin , note that there is a space after "spin ".

4) If I type any vowel before "o" it should render "o", example: gambuo becomes gambo.
would this be possible? I'm not very familiar with Javascript even though I can modify it.

Unicode Characters

Aug 2, 2007

Problem:

Depending on an input value, I would like to output greek characters
(f. e. those between U+03B1 to U+03C9. One way would be to define two
arrays: one with the possible input values ("abgde...") and a second
array with the corresponding values ("u03b1u03b2u03b3...").

But I hoped I could skip the second by a computation, f.e. "g" has
index 2 in the first array, so output "u03b1"+2.

This does not work (of course). But do I have a chance to "compute"
the output value?

Getting Div Width In Characters

Nov 18, 2005

I have a bordered div with some text in it. Some of the text is one long string and thus runs outside of the div. The div stretches out to the width of the browser window so that long string of text runs all the way out past the edge of the scrollbar.

Is there a way I can use JavaScript to detect the width of the div from the edge of one border to the next and then convert that number into the number of characters that can fill that width?

Replacing Characters

Mar 6, 2006

I have a script which gathers information from a form and, if needed, writes this info to a 'preview' window. At times {tokens} are used in place of real html tags. How can I tell the script to look for "{" and "}" and replace them, respectively, with "<" and ">".

I tried using "str = str.replace(/{/g, "<").replace(/}/g, ">");" but that didn't work. The script in question is being written by PHP... thus, may be generating a syntax-based failure. Any ideas?

Showing Illegal Characters

Jul 23, 2005

I am building a web page to show a TCP/IP raw packet.

I need to show "special characters" on the web page I am working on.
When I say "special characters" i am talking about tabs, whitespace,
crazy unicode characters, etc etc.

What is the best way to present this to the user?

I am thinking that a large textarea is the only way to display it so it
retains all the special characters.
