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.

Check If Field Is Numeric, But Allow Certain Characters..?

Oct 12, 2006

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?

Test A Field For Valid Characters Using REGEX?

Dec 7, 2010

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;

Code JavaScript:
if(document.getElementById('RegisForm_Username').value == /[^a-zA-Z 0-9]/g)
{

your username must be alphanumeric (consisting of the letters A-Z or numbers 0-9) and cannot have any special characters.");return false;}

Check If First 2 Letters Equal Certain Characters In Input Field?

Jun 14, 2011

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'

Removing Unwanted Characters From A Passed Value And Passing To Input Field

Oct 20, 2009

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?

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?

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)

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.

Russian Characters In A Cookie

Representing [ And ] Characters In Function

Oct 17, 2007

i have checkbox to call function

<INPUT TYPE = "checkbox" NAME = "AttributeValue[1]" VALUE = "Yes"

The function itself has this:

if (form.AttributeValue[1].checked) {

(more script) }

That doesn't work because I believe it is interpreting the [ ] characters
as representing array (I think).

How is syntax for AttributeValue[1] as literal value in function?

Does this make sense?

Displaying Special Characters In A <div>

Jul 20, 2005

I have a problem displaying a divbox containing a html-textarea -
everything works fine with "normal" characters. However, when the
textarea contains special chars like <P> or ' , the box fails to show:

function show(divbox)
{
divbox.style.display=''
}

<div id="divbox" style="display:none" >
<form action="action.php" method="post>
<textarea name ="txt">Text</textarea>
</form>
</div>

If the Text in the textarea is for instance
HERE IS A "QUOTE"

it works fine, while
HERE IS A 'QUOTE'
produces an error

<br>-tags works fine, but
<p>-tags doesn't

Treating Special Characters

Jul 20, 2005

I have a number of scripts that take special characters and convert them
to their ascii equivalents and them store them in the database.

However I am running into a problem that I have some of those fields are
loaded to an array and inserted into cells dynamically. As an example
the array would be:

var my_array = [ ["52","Source Data"], ["19","Body &amp;
Soap"] ];

Then I have some javascript that creates the cell and inserts the value
into a cell text node like:

var x = my_array[1][1]; // this would be "Body &amp; Soap"

//create the cell
myTD=document.createElement("TD");

//create the text node
myText=document.createTextNode(x);

// Appends each node following the structure.
myTD.appendChild(myText);

What I see on the output is: "Body &amp; Soap"

What I should see is: "Body & Soap"

Anyone know how to get around this?
