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:
1,2,3,4,5
...it returns:
1,2,3,4,5,

I tried the code bellow, but it didn't work:
<script type="text/javascript">
$("img").this.src = this.src.replace("1","");
</script>
My html code is this:
<img src="images/1backg.png" />
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.

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 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?
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?

View 3 Replies View RelatedSo I've got an array called questions_raw
questions raw = [
["<Q1> Question",
"choice1","choice2", "choice3"],
["<Q2> Question",
[Code]....
And I want to list all of the questions, but not the choices/answers. So far, I've managed to list just the questions, but because another function randomly sorts them, I need to sort them back into numerical order for a separate function (displaying the questions)
I use characters (>,^) at the front to separate them into different answer types (just to explain the code)
I try this to cut each string down so that they can be sorted numerically/alphebetically -
function linearlist()
{
var list = [];
var tempStr = "";

But it doesn't like it - because "it has no method charAt"
Is it just that you have to put the [l] in every time you call a variable?

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?
How can I remove the currency symbols from a string, for example I could be dealing with strings like -

Is there a single function that can remove the currency symbol no matter what it is?
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.

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++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
