Interacting With Textareas
Jun 16, 2006
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 have two windows, one, the 'main' window which contains a blog entry, and a 'child' window that contains item in an ordered list. Each item A-Z has a corresponding word a-z in the main window. Whever the user puts his mouse over, or clicks on a-z in the main window, I'd like the corresponding item in the child window to be brought to the top and highlighted.
I haven't had much luck looking around for answer because I'm not sure what I should be looking for. Even just some search terms would be helpful (though I prefer a nice solution!).

I'm using IFRAME to connect back to my ASP.NET page in order to fetch the FreeBox HTML Editor html contents and scripts (i do this apprach because the html editor is fairly heafty to send to the user when most dont use it on our site instead deferring to a user request before actually sending down the code via AJAX or in this case an IFRAME). Code:

A "dough-nut" type wheel will be located in the bottom center of the web page. The wheel will be divided into 3 tiles. One will be able to click this and drag to turn the wheel. An arrow will be centered directly above it in order to show which tile on the wheel is selected. Above the arrow will be a go button, once the go button is pressed, a user will be directed to the page that the tile leads to. The go button will inherit the image on the selected tile.
So first off, is this possible? Next, what code type (I think javascript but I am not sure) or software will I have to use to do this? Finally, I need a general idea of what the code would look like.

Within my site I have the following code:-
Code:
<form>
<button onClick="changeVideo(2)" type="button"/>
</form>
<object id="videoPlayer" type="application/x-shockwave-flash" data="http://www.mysite.com/videoplayer.swf">
[code]....
By default when my site loads the flash file gets the value of currentItem from Flashvars and does what it needs to do with this value. The flash file in question is just a basic video player and the id of the video to be played is retrieved from flashvars.
However I want users to now be able to click the button in my form and then the value of flashvars in my videoPlayer object will change to the value passed in the changeVideo() function i.e. in the above example value="currentVideo=1" will become value="currentVideo=2".
That's the easy part I think but what I then need to do is get the flash file itself to load this video without a page refresh but I have no idea how to get the flash file to recognise this value once it has already loaded. What exactly are my best options here?:-
1. Reload the flash component via ajax every time a user selects a new video i.e. every time changeVideo() is fired?

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.
Code:
<!- * * * * * * * * * * * * O.S. Question * * * * * * * * * * * * * * * -->

<div id="left">
<img src="yes.png" onclick="document.getElementById('moreinfo22').style.display =

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?

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 ?
