I have a form with a textarea field. I want to validate the input from
the textarea using javascript. Suppose I want to check that the user
has not entered the string:
"Hello
World!"
To do this I am using the script:
form["text"].value == "Hello
World"
But this gives an "unterminated string constant error" because the
browser converts this to:
form["text"].value == "Hello
World"
So how do I do my check?
Let's say I have a string:
div.innerHTML = "<a onclick='foo(""+myWord+"");'></a>";
in IE only (tested version 7) if var myWord = "English" then it works
fine but if var myWord = "Modifier Chau00EEnes" then I get "Unterminated
string constant" error.
What fix would you suggest to keep div.innerHTML = "" format?
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'm getting an error message come up in IE6 when somenone subscribes to my newsletter from my home page (either from the drop down hover box form or the left hand form) here .
After entering a name and email address
I get:

When I click NO I then get a second small windows popup which says:

I've looked at lines 4 and 43 of my thanks.php page (the page subscribers get when they fill out the form but before they double optin via the email) and I can't find anything wrong. I guess the first message expects a semicolon and the second obviously a closing bracket. Code:

I had a difficult time figuring out how to get or test the last character of a string with javascript.
I found plenty of removing the last character, but not for just checking what the last character of a string is using javascript.
// create string
var str = new String("No Periods Allowed.");
// alternatively get string from field:
// var str = document.getElementById('textbox').value;

Well, finding that easily on a search would have saved me some time.
I want to insert a character into a string. Whats the best way of doing this? So if I want to insert a hyphen(-) into the string 'oneway' giving me 'one-way'.

The last line in this JS function should remove the final comma from the end of the given string... but for some reason, it does not.Instead of returning something like:

Is there anything 'wrong' with setting the value of a drop down menu
using the following?
document.frmStep1.drpInvaddress.value = 'A1020761603!>>R2'
This string is a key in our database that I have no control over and I
want to set the value of the menu according to this value because it
is unique. I suspect that the '' or the '>' or the '!' is making
Javascript think that this is a different type of data than string.
Is there a way to 'force' Javascript to interpret this as string?
I am trying to split out a string. E.G "Australia - VIC". I want to remove everything before the -. The line of code I am using to do this is: var state = optionText.replace(/.* - /,""); This works in IE7, but in all other browsers is only removing the - resulting in "Australia VIC" rather than the desired "VIC"

I am trying to extract just a single digit character from a string.
my string is 'constructions-01_0'
I want to extract the very last character, the 0.
how do I do this?
Should I use String.match() or String.split() methods or is there another method I shoud use?
And what should the regExp be to get that last digit?
also separately I want to get the double digit and put that into another string, the 01.
How do I extract just that bit?

Lets say I wanted store a long string of text into a local storage member on a browser using javascript.
window.localStorage.setItem("key",longStringText);
Now lets assume that the text itself contains characters outside of the normal ISO-8859-1 character set (like asian or russian characters). Would the individual char values be stored as one byte or two bytes?
"hello" -> 5 * 1 bytes = 5 (normal 8859 character sets)
"hello" -> 5 * 2 bytes = 10 (unicode or an extended character set size).
Is ISO-8859-1 still stored like ASCII once was as 8 bits? Or is it 16? If I was to use a 2 byte character set then would that cut the size of my allocated local storage space by half?
Why cannot I send a string which contains "&" character to web server? The web server returns an error of undefined object.
