I am trying to retrieved the value of the textarea with the newline preserved without having to submit the form to the server. Does anyone knows how to? I tried soft and hard wrap but both does not seems to affect the input in anyway.
Example : <form name=frm> <textarea name=ta wrap="soft"></textarea> </form> <script language=javascript> alert(document.frm.ta.value) // <-- the alerted value should look exactly as what is entered in the textbox. </script>
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
I am trying to replace new line character with the <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
only have test one browser - Mozilla - but have the impression, that newlines when setting innerHTML doesn't go down very well with the browser. Is this sufficient for causing a hard crash or at least an exception? Can anyone verify that? (Just a guess now at the moment)
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 replace all newline characters with <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine).
This of course print each word on a new line in the browser. The problem is when the user copies and pastes the text, it appears as one long string of text with no breaks. Now consider the following script:
In textareas or input textboxes, when you dynamically add ' ' to the textbox's value, is it automatically converted to ' '? If it does, in what browsers does this happen? Firefox (and other Geckos)? Opera? Konqueror?
my javascript does not working after I retrieve a record that contains square symbol in the database. The square symbol should be a newline in a textarea. This is how the record "looks" in the table: [URL]
I am inserting the record using ASP and the value with square symbol is the value from a textarea with newline/enter. After that I retrieve the value using ASP and pass it to javascript and then the page is not working. If I retrieve other record which contain no square symbol then the script is working.
How would i change back to the default length of textarea?

I've got this little 'textarea' script..see the code below. Now there is something strange with it. When I disable javascript from within IE 6.0, it still seems to function well... how come ?
Also I would like to build in one thing extra.. Whenever one of the buttons B or C is pressed there is a tag placed within the textarea, like it should. However I don't want the tags to be counted up to the textcount total. What do I need to adjust in the code to achieve that ? Code:
how to make a DIV into a textarea. I've noticed that Facebook does this and so does a lot of Google's stuff. Just looking to see how they pull that off.
really need some help with validating a textarea box. basically i have a text area box that must not have more the 910 characters entered and they must not be spread over more than 23 lines. I could check the total length but the problem is people could enter 1 character per line so you would end up with 910 lines.
Is there a way to detect which textarea the cursor is positioned in? I would not want to attach 'onkeypress' to all textareas to detect which one I am presently in ... or is this the only option?
I need to create a page that allows users to copy the contents of a MS Word document and paste them into a textarea. All fine and dandy...but the tabs. I don't need to keep the formatting, just the tabs. Is there any way to detect the tabs and change them to four spaces or something similar? If you have any other ideas please let me know.
I'm using a third party libray and I can drag a diveand resize it. The issue is, I have a textarea inside of it and I need to resize the width of textarea and height of textarea along with it.
I know what the width and height of the div will be when it finishes dragging (in "px"), so how do I convert the width and height in "px" to the cols and rows of a textarea?
I have a variable, divs, which contains the DIV's and divs[x] contains the actual DIV I need.
