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"
View 1 Replies View RelatedI'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();
}}}}

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?

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?
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?
below is my code and i cant seem to figure out how i can loop the string and find the location of letter "a" in the string and display it like "1 3 17" ... i cant seem to figure out what i am doing wrong in the loop and keep getting "1 1" ... Thanks before hand!
