Character Codes For Newlines In Textareas
Aug 25, 2006
I have some Javascript code that reads and sometimes sets the content of
a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?
Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?

PHP has a function called nl2br() which takes all the newlines in a
string and turns them into break tags <br>. I need to do the same in
javascript. Is this about right? I'm not sure how one is supposed to
reference invisible characters in Javascript strings. I took an example
on the web and tried to modify it to my uses.
function nl2br_js(myString) {
var regX = /
/gi ;
s = new String(myString);
s = s.replace(regX, "<br />
");
return s;
}
After looking around quite a bit using Google, I still couldn't find
out what the gi in the above example is for. What is it?

I've written this javascript that puts lines of text into a readonly textarea, each line ends with a newline character. I have a function that checks that no duplicates exist, it does this by splitting the textarea by newlines into an array. This works as it should in Firefox, but not in IE. Code:

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..

I'm trying to write a small little bookmarklet to insert some text into a textarea on a website I frequent. The first problem I ran into was that while the textarea I wanted to mess with was named, the form wasn't. To get around this I tried:
window.document.forms[0].comment_body.value
which, for some reason, sometimes worked. But not every time. Then I found getElementsByName but I can't seem to get that working either. Here's my latest attempt:
javascript:function wlcauto() {elements = document.getElementsByName(comment_body);V = 'bla bla bla bla bla'elements.value = V;}wlcauto();void(null)
Anyone have any ideas or links to something?

I am loading a page with textareas containing text. By the default, the cursor goes at the beginning of the text.
I would like to position the cursor at the end of the text instead.
Does anyone have a quick script to handle this?

Is it possible to have text formatting inside textareas? I mean, can you show parts of text in a textarea as bold, italic, underlined, or such? If so, how's that work?

I am trying to read something like the following in a textarea
Code:
|Note|Dur:4th|Pos:n1
|Note|Dur:4th|Pos:n-3
|Note|Dur:4th|Pos:n0
|Note|Dur:4th|Pos:#2
|Note|Dur:4th|Pos:n3
|Note|Dur:4th|Pos:n-2
|Note|Dur:4th|Pos:#-2
There are other types of records but I am only interested in the ones which start with "|Note|". The field after "Pos:" will be compared to members of:
Code:
var offsets = [ "n-6", "#-6", "n-5", "#-5", "n-4", "n-3", ... ]
If there are other fields after Pos:, there will be a "|" or "!" instead of the end of the line.
I was able to run the split(" ") command against the textarea to break it into separate lines, but I couldn't search those lines.

Basically i have a function that depending on which picture you click (one for "yes" and other for "no") it will make visible a textarea .
However right now if i click in "yes" it will display me the textarea for yes, and afterwards if i click "no" it will display both textareas, for yes and no. I want everytime i click on yes it will hide the "no" textarea and the same for when i click the "no" textarea, it will hide the "yes" textarea.

A form on my website's contact -us HTML page has two fields
1) subject
2) message
When the page loads for the first time I want these two boxes to display messages like "**Enter subject here**" and "**Enter Message here**".
I found that we can do this by using the "value" attribute of the text box, is this the best way ??.. What alternatives do I have to achieve this ?

I have the below code in a form to re-form the characters entered into it
into a dollar amount and also only accept numeric characters. However, when
I enter the numbers "113" (which appears after the reformatting process as
1.13), it no longer accepts any other characters. I also am not able to
deleted from the text box that I entered it in. I was wondering if anyone
has any ideas why this is happening.
