I am trying to detect whether a user entered text in a textarea
or hit the delete/backspace button (thus, erasing something). Once
that is detected, I would like to set "var bSaveRequired = true;". It
would be great if this function worked cross-browser -- IE 6.0 and
Firefox.
I'm using a text area to display textual updates to a user from the server. I'm inserting the text at the bottom of the textarea and need to set the scrollbar to the bottom of the textarea after every update. The problem is that the onChange event only fires if the user actually changes something in the text area, not if it is changed by an ajax update.Does anyone know of a way to detect if there has been an update to a textarea that was NOT triggered by a user?

I have this comment area that after clicking submit i will append the new comment in the list of comments through ajax... i got one problem though, everything is working perfectly well except for the textarea that won't change back to it's default size...

View 1 Replies View RelatedI have an input field where users can input a number, and JavaScript calculates a result and displays it on the page. In order to have the best user experience, I want JavaScript to perform the calculation whenever the number in the field is changed. However, the "change" event works only when the input loses focus.
I have added "keyup" as a second event for the calculation to be performed, which covers many cases of user input. However, this is still not perfect, because the user could paste a value into the box or change the value in some other way (i.e. clicking the up and down arrows on compatible browsers).
Is there an event that fires whenever the value in the input changes, regardless of the focus of the input? Is there some other way to work around this problem? It seems like this would be the kind of thing that would have a thousand hits on Google, but I can't seem to find anything.
My code:

function onLoadFunc(){
if(document.addEventListener){
document.getElementById("wm_buy_amt_input").addEventListener("keyup",

I am trying to change to change the background of a li element when its own class is changing
i tried :
$("ul#slide-nav li").each(function() {
if ( $(this).hasClass("selected") ){
$(this).css("background-color","black");
}else{
$(this).css("background-color","gray");
}});
This seems to be working I think., but once the class change again it doesn't work.. how can it loop for ever?

View 1 Replies View RelatedI've been trying to change the text in a textarea element to no avail. I'm using the following to change the text:
$(inlineEditor.CurrentEditCollection).find('#resource_description').each(function(){
this.val(vals.value);
});
vals.value contains the text. The Textarea element is in a TD in a TR that is contained in inlineEditor.CurrentEditCollection
The selector seems to find the element just fine but the text will not change.
I would like to be able to change the "wrap" attribute for a textarea with javascript. That is unless you can provide a cross browser solution in css2, giving me the ability to just modify the css attributes.

View 3 Replies View RelatedI want a set up some type of array/ IF statement within a textarea.
This is what i want it to do...
If textarea text = "[example]" then change colour of font #383838
I need it as a basic validation method to ensure the user has typed in the correct text. for example if the member uses { in stead of [ it will not turn a different colour and the user ill no they have not typed it in correct.
I presumed there would be some JQuery code out there that would enable this but I can't find it. ( or even know what search term to use )
If you've used the Google Gmail spell checker you know that it
'changes' the text area to another type of control that lets them show
hyperlinks for the incorrect words. How does Google change the

simple, I just have no clue because I'm fairly new to DHTML. Any
examples would be greatly appreciated.

I want to implement a text input box for SMS text messages and the messages are limited to 160 characters (including spaces, etc.). I would like the font color of the text to be green as the user types and any text beyond 160 characters to be red. I would like to do this with one input box, the same box that the user is typing in not a separate display box. This will be on the users local PC it won't be on the Internet.

If I highlight a word in the textarea and hit the Bold, Italic and Underline buttons it changes the appearance of the word.

I would to change the color of some td cells if there is text in it. Right now this code does the job, but it changes the color of evry table. I'd like to know a way to do this on one table in my page and not all of them.

var TDs=document.getElementsByTagName('td')
var length=TDs.length;

Why is it that you need the return keyword?
Where does the argument event come from?
