I need to send the contents of a ExtJS Textarea to the backend server for saving (autosave facility) as the user types in. How do I buffer the contents and push the buffer to the server after some threshold value. I've done as below:

any ideas?
I have a pretty basic set of things I want to do: Capture key press, compare against an allowed list, block keys that are not in that list, replace a space by a dash if entered. As this is happening, I have a span I wanted to be updated with the live values. The username field at [URL] is exactly what I am trying to do, though I have trouble dissecting how they did it. Here is my attempt, which is off by one keypress for some reason.

I'm using a form where a user enters data in a textarea which is then copied to all other textareas on the page. Currently I have it working for 2 textareas using this code:

the code is like following:

can i assign a variable to rows based on my contents length? or
javascript has any internal attribute i can use?
I'm working on a text editor with simple BBCode tags, like . It works perfectly in firefox and chrome, but not in Internet Explorer.
The js function in question:
Do we even have a selection?
The variable textArea is, of course, a <textarea>.
I call this function with the onclick event of a button, like this:
In Chrome and FF, clicking the button inserts the tags, just as it should. In IE, nothing happens.
I have another js function that formats the text and displays it, which works in all browsers. No idea why this doesn't. Any reason this wouldn't work in IE? Anything I can do to make it work?
I've got a form which has a couple of inputs. The 1st is just a text input and the 2nd a textarea.
I have it so that when someone types into the 1st input some javascript causes a div elsewhere on the page to update with whatever's being typed.
html:
<div class="input text required">
<label for="CampaignTitle">Title</label>
<input name="data[Campaign][title]" type="text" maxlength="76" id="CampaignTitle" />

My code is not working:
I have Validation working across a form (I fire it several times before Submit to check sections of the form), and a tinyMCE editor working in 1 textarea.I want to move the contents of the tinyMCE iframe into the textarea before (that's the key here - before) the Submit button is pressed so that the contents can be validated in the section before Submit. I've used tinyMCE.triggerSave(); in several ways to move contents and then fire Validation before Submit. None work. I am beginning to believe that tinyMCE contents cannot be moved by any Javascript other than Submit, but I don't see that stated anywhere. In tinyMCE, I've tried onchange_callback: and handle_node_ change_callback: to fire functions with triggerSave and other saving commands. I can get the contents of tinyMCE to validate when I press Submit twice (others have noted this peculiarity), but not in any other way. Also, when errors are corrected in tinyMCE, Validation does not revalidate until Submit is pressed.
2 questions - how to move tinyMCE contents into the textarea without hitting Submit? Does CKEditor allow updates other than via Submit, and if so, where's a tutorial or example? Here's an example of code that is supposed to be triggered by tinyMCE's onchange_callback, but only triggers upon the second click on Submit.
function tinyMCESetValue(inst)
{
var content = tinyMCE.activeEditor.getContent();[code].....
I am trying to create a text area input filed for user input, and i want to be able to allow the user to format thier text, just like the ones used in this user forum. I am writing my website in html, php, javascript and css with a MySql database. I am trying to understand how to create such an format-able text area for input.
View 1 Replies View RelatedI was playing around with the compose feature of gmail today and I noticed that it seemed to have an extremely intelligent auto-save feature. What intrigued me about it was that it only seemed to auto-save the document when you were not working on it and when there was actually something that needed to be done.
However the most interesting (i.e., bit that stumped me) was how while in the middle of auto-uploading a large attached file I am able to edit the e-mail and yet when it has finished uploading the attachment (and the page seemingly refreshes) the changes I made to the e-mail are still there.
Could anyone be so kind as to enlighten me as to just how exactly the auto-save feature works (as I am interested implementing something similar for my own site), especially in the region of attachment handling.
I know that they must have some kind of JavaScript on-key-press callback that detects when you are working on a document but that is about all I can extrapolate.
I have an autosave feature that, well... autosaves every minute. Now I could very well become the biggest abuser of my own feature. I currently have 8 windows open - I tend to just leave windows open for a long time. As a result, the javascript would be running every minute saving, creating unnecessary load on the server.
How could I make the autosave smart and only save if they are actively "working" with it? The only thing I can really think of is to have like a variable that sets to true whenever something happens, set to false whenever it saves, and only save when the var is true. Problem is, I have a lot of functions for events that I would need to attach it to... I'm sure I would miss it somewhere.
jQuery Plugin: [URL]. I've been trying for 3days to get this plugin to work, I've contacted the developers and no response. the demo on the site seems to work with a json output but the downloaded code & example does not work. I'm trying to get it to work with PHP as the backend and nothing. The instructions are very vague like a lot of jquery plugins. Are there any developers or experience jquery plugin users that can assist with telling me how to get this plugin to work correctly?

I am trying to create a web page in which the contents of one selection list
depends upon which element in another selection list is chosen, but where
the information to populate the first selection list comves from an SQL
database on the web server.
There are a couple of these situations in my application but, for example,
the first list might be a list of counties, and the second list a list of
states/provinces. Obviously the names of counties depend upon which
state/province is chosen, but there are too many possibilities to be able to
embed them within the web page itself. So when the user selects a
state/province I need to go to the server to ask for the list of counties.
I have seen a number of posts that sort of address this issue. For example
it is suggested to use <script src="a URL"/> to ask the server side code to
send up data of type "text/javascript". However the examples do not seem to
address how the server side code would know which state/province the user
had selected.
If there is a web site that addresses this sort of thing, I would appreciate
any pointers.
I have a php page that has a button on it when clicked shows a div (previously hidden) in the middle of the page this div contains a table with rows.Each row has an image acting as a button and a series of fields that are populated from a database.One of the fields is a quantity box I want to be able to change the value in this box and click on the submit img and have it submit this info (including the altered quantity) back to the php page or to the submit function so that I can then access the values.
View 4 Replies View RelatedI have one form on a page with 'n' text input fields grouped in blocks of the same input fields. Something like this:
<div id="block1">
name_1
lastname_1
address_1
phone_1
...
</div>
<div id="block2">
name_2
lastname_2
address_2
phone_2
...
</div>
...
The number of fields for each block varies because the page is constructed by a server function. What I want to implement is move up and a move down buttons on each block to move what the user has entered in say, block 4, to block 3 (and move the block 3 contents to block 4). And the contrary too.

I'm now working on kind of invoice form which in it the user can add as much input field as he wants.
The problem is that after adding a new input field - the content in the other fields is deleted.
Code:
On a single form, I need to capture the users input on this input box
HTML Code:
<p>
<label for="Student ID">Student ID
</label>
<input type="text" name="sesStudID" />
</p>
to this input box HTML Code: <p><label for="User Name">User Name</label><input type="text" name="sesUserName" disabled="disabled" /></p> so as the user inputs to the first input box it will at the same time appear on the second input box.
I wrote a script that tracks the number of characters a user types into a text box. It has a limit you can set, and when that limit is reached I would like to block the user from entering any more text.
How can I block the user from typing characters in the textarea?
