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;
[Code]....
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:
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"
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"
what character occurs most frequently in a textarea. Do I really have to store every single character in an array and then sort it? Is there a Regular Expression for this?
I've got the following form validation script. How can I include the quote marks as a bad character?
I tried: var bad_email_chars="/!#$%&*+^ ()_-=|~`?;:,'""" It didn't help.
if(form1.elements(i).name=="text_website") { var bad_email_chars="/!#$%&*+^ ()_-=|~`?;:,'" var h,j for(h=0;h<bad_email_chars.length;h++) { for(j=0;j<input_str.length;j++) { if(bad_email_chars.charAt(h)==input_str.charAt(j)) { alert("you have atleast one bad character in you website address. You may not submit this form until you correct this.") window.event.returnValue=false form1.elements(i).focus(); }}}}
Also, How do I format with indentations and as non wraping text the messages I send to this forum?
I am building a string inside a variable prior to printing it on screen as follows : myclock += hours+':'+minutes; where "hours" and "minutes" are variables initialised elsewhere. How can I add a carriage return or new line character to the end of this line, so that anything else cocatenated to this variable is displayed on the next line.

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?
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?
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..
