Get The Last Character Of String?

Feb 4, 2011

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.

Invalid Character In String Reference

Jul 23, 2005

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?

Newline Character In String Constant

Jul 23, 2005

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?

{
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?

Unicode + Escape Character = IE Unterminated String Constant Error!

Nov 1, 2007

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?

Store A Long String Of Text Into A Local Storage Member On A Browser - Character Data Sizes In JS

Oct 16, 2009

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?

Check And Alert If The First Character Is A Special Character?

May 22, 2009

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..
