In a textarea, is there a javascript (or something in php) that will convert carriage returns to spaces when submitted? The textarea on these forums does what I'm trying to accomplish but I've looked at the code and I cannot figure out how it's done.
View 4 RepliesI have a page with a div on it. The div displays a user comment. When
the user logs into this page, their current comment is pulled from a db
and displayed in the div. The user can edit the comment through a
pop-up that contains a textarea. When the user hits OK on the pop-up,
the text in the textarea is sent to a function on the main page. The
function inserts the text into the div's text node.
Please don't ask why I'm making this so complicated - there are other
things going on on the page and the pop-up that are irrelevant to my
problem.
Everything works perfectly except when the user puts carriage returns
in their comment. For some reason I can't get the carriage returns to
show up in the div. BUT! When they view the existing comment in the
div (the one pulled from the database) the carriage returns are
displayed. That initial display does not use any javascript - it's
just php so the page is initially rendered with the text in the div.
So it seems that when I programmatically put text into my div, the
carriage returns don't show. But if the page is rendered with the text
already there, the carriage returns do show.
This seems like it should be so simple, what am I doing wrong??? Do I
have to replace the carriage returns with a different character (e.g.
<br>,
,
,
,
)? Or is there a css setting for the div?
Either I'm having a really dim Friday, or something strange is going on. I'm trying to add a method to the Validator plugin, using the following regex:

This JS limits the input characters into the form. How do I modify it
so that it also allows CARRIAGE RETURN and BACKSPACE (for making text
correction)?
Due to the template engine I am using, I cannot use IF/ELSE statement.
<form>
<textarea name="event_description" ONKEYPRESS="if (document.layers)
var c = event.which;
else if (document.all)
var c = event.keyCode;
else
var c = event.charCode;
var s = String.fromCharCode(c);
return /[0-9a-zA-Zs,.?!@#$%&*()-]/.test(s);"></

The function below is triggered via the "onkeyup" event of a text box. I need to test to see if the [enter] key has been pressed, and if so, call a function. With the code below, the pressing of the enter key is traped, but the ascii value for the last "printable" characteris displayed and not chr(13).

I am trying to do a small website for our family to keep track of each other's home address and etc. Using asp for the codes .. (Its been ages since I indulge myself). I have 2 forms.
In which in FormA, I will key in the following address
666, ST Avenue
#03-09
Anchor View Residence
123456
When I click on submit
it shows this on FormB
666, ST Avenue #03-09 Anchor View Residence 123456
How do I get it to be shown as
666, ST Avenue
#03-09
Anchor View Residence
123456
in FormB
In my formB.asp, for the particular code, all I wrote was {Form.address}.
I think I have the regex side of this script worked out. But I need to get everything into an array for regex to read. Is there a way to use tokenizer to read everything before a carriage return? Each line should be added to an array for the regex to analyze and parse as needed. It's been ages since I touched tokenizer, so I forgot most of it. This is the text area in the html that the script should reference.

I'm trying to load an ASP recordset into a javascript array via an ASP array. The way I've been attempting to do it is by having ASP "Response.Write()" the javascript code that builds the javascript array. It ALMOST works :rolleyes:
The problem I'm having is that the ASP writes the different javascript lines as one long line (ie. no carriage returns). Therefore, the javascript lines are not recognized. When I take the source code and manually separate the lines produced...then when I run the modified source, it works fine. Code:
I have a calendar where i write my events.
If I have 2 events in the same day, how to put a carriage return between the
events in the alert part of message?
For example, I want this alert message:
Event one to the office.
Event two to the store.
The string that I use actually is:
fAddEvent(2003,9,17," Event one. Event two.","alert('Event one to the
office. Event two to the store.');","#00ff00","red");
I am building a string inside a variable prior to printing it on screen as follows :
myclock += hours+':'+minutes; where "hours" and "minutes" are variables initialised elsewhere. How can I add a carriage return or new line character to the end of this line, so that anything else cocatenated to this variable is displayed on the next line.
I'm creating a new email in javascript via outlook. When i try entering a line break " etc, Outlook just ignores it completely. I've tried using "%0D%0A" and "fromCharCode(10)" as well but it doesnt seem to read it as a line break. Is there any way to code it so that a line break or a carriage return appears on outlook?

View 5 Replies View RelatedI would like to create a program which converts some letters into different ones.
1) I want 2 text areas (input and output) + "convert" button
2) if I type in the input area the letters "ea" I would like it to be converted into "a", so that If I type "cambrea" and press "submit" the output text will have "cambra".
3) if I type "e " which is (e+space) I want it to be converted into " " which is "space" example: if I type the word "spine " it should be converted into "spin , note that there is a space after "spin ".
4) If I type any vowel before "o" it should render "o", example: gambuo becomes gambo.
would this be possible? I'm not very familiar with Javascript even though I can modify it.
how can we get a return from a value not yet set, like the behaviour of the prompt and confirm dialogues? specifically in regard to the xmlhttprequest file load methods, or to send a click event to a file object and return its value once user interaction's occurred.
View 3 Replies View RelatedI'm trying to figure out the width of all the ul element inside a li, which works fine for the subnav. But the ul for the subsub nav always returns a width of 0, which is incorrect.You can see an example on this page. The second tab is the one that has a sub navigation.I use a simple line like this to get the with of the ul element
Code:
var e_size = $("#testnav ul").width();
//shows 95 with alert

I developed a Grid that sometimes resides within a table. The Grid is created with the DOM and inserted in its parent element. Problem is that IE returns offsetWidth/offsetHeight 0 when you check its offsetWidth.
For example, the following code will return 0, while Firefox returns its correct width.
Code:
<table border="1">
<tr>
<td id="myCell">
Some text goes here...
<script type="text/javascript">
alert(document.getElementById("myCell").offsetWidth);
</script>
</td>
</tr>
</table>
I read somewhere that IE renders the table once it has read the entire table, so my guess is that offsetWidth returns 0 because the table is not yet rendered and its not part of the DOM?
Anyway, if anybody would know how to avoid this it would be great. This problem does not appear inside a DIV, but in this very case it must be inside a table...
I want to know how to find out the viewport height in IE. I have been trying to use document.body.clientHeight, which is supposedly exactly what I am after, but the results were always way too small to be the correct one.
As a test, I whacked a div in my page and made it 4000px tall, and ran document.body.clientHeight from IE's debugger and it returned a number over 4000px. It seems as thought clientHeight is actually returning the total height of the document, not the viewport size.
I have a homework assignment which is pretty simple. It is a grade calculator that uses arrays to gather the grades from the user. This is what I have for the problematic section:
var homework = new Array(2);/* The grades entered by the user for Homework 1, 2, and 3 */
var project = new Array (3);/* The grades entered by the user for Project 1, 2, 3, and 4 */

My problem is the document.write portion of the code, where it is supposed to return either homework[0], project [0], or exam[0], it instead returns undefined. There is no problem with any other subscript. And yes, it does successfully prompt me for each of the [0] subscripts in the first part of the code. Am I just missing something that is right in front of my face? Does all arrays not start with the [0] subscript?
HTML Code:<div class="drag q1 bar" style="top: 10px; left: 0px; position: absolute;">b</div>i assign variables like so:

Suppose I have the following inside a function:Code JavaScript:document.getElementById('display_content').innerHTML = "hello";The above works.However, when I define it like the following it says display_content is null on firefox error console.

I'm working on a project that requires me to take numerous classes and put these within a list-item. I have been trying to do this with different methods, such as before, insertBefore and Prepend. All these methods have had the same result.
Instead of inserting a single <li> in front of the class, a complete list-item has been inserted (<li></li>.
this is the code I'm using:
<script type="text/javascript">
$(document).ready(function(){
$('.ngg-gallery-thumbnail').insertBefore('<li>');

In Firebug when I rollover the SelectList variable it certainly looks like an array.

I'm brand new to jquery, and am trying to set up a dynamic navigation dropdown which is populated with XML by our system (which I can't change.) For some reason, IE6 is showing space where the unused <li></li> tags are. I am trying to create a jquery code which will detect whether or not a link is present in the <li> so I can turn the display off or on dynamically. The relevant jquery code is here:[code]It should eventually appear like this, the way it does in Firefox due to CSS styling:[code]Which means that somehow, it is reading the <a> even when there isn't one.
