Stopping User From Pasting Into A Text Box

Dec 21, 2005

I know this might sound weird, but I have a form where I ask the user to
enter their email address in one text box and then again in a confirm email
text box to make sure that they have entered it correctly.

My problem is that many users appear to type their email address in the
first box and then copy and paste it into the 2nd box.

If they typed it incorrectly the first time then all they have done is
confirmed that it is wrong.

Is there anyway that I can stop them pasting into the confirm email text box
so that they have to type it twice?

AJAX :: Facebook Login With Calls?

May 4, 2011

Below I have a facebook login/logout script for my website. The login works fine. The AJAX requests the php file, waits for the "Success" response, and then reloads the page. The logout doesn't. Instead the browser goes to the PHP file with just the word "Success" printed on it. I've separated the xml request as a separate function but that doesn't appear to solve it either. code...

AJAX :: Chat System Like Facebook ?

Mar 30, 2010

A lot of websites have a chat system built into them.

I assume they work something like this:

User1 enters message

AJAX posts message to server

Server holds message

User2 does ajax get to check if there is a message

If there is a message when User2 checks the server responds to the ajax request accordingly Rinse, repeat.

I guess ultimately what I am asking is there an interval set to constantly check the server? Or is there another way of doing it.

Ajax :: Indexable And Facebook Functionality - Div Appears Empty In The Source

Mar 17, 2011

I've been trying to learn Ajax and have been following these tutorials:- [URL] I now have it so that in my site when a user clicks tabs the content gets loaded into an originally empty right hand div without any page refresh. However I notice that as content gets loaded into the page if you right click and view source the content is not there and the div appears empty in the source. I understand why this is but I also understand that this will make the site a lot less seo friendly which brings me to my questions:-

1.Facebook pages seem to load in their content without any page refresh at all yet it seems this is actual indexable content being loaded in live or am I wrong?

2. If this is the case that they load in actual indexable content live at such speed how can I do this because I want the content in my loaded sections to be indexable yet also want the site to flow seamlessly like facebook with no page refresh at all? Are there any examples/tutorials on this?

3. I've also noticed facebook urls change as the user switch tabs yet the page itself doesn't refresh. How can I do this too again whilst keeping th page as indexable as it would be using a regular page based layout?

Mar 19, 2010

This should be fairly straightforward but I'm having some unexpected trouble.

I have a form with an input [code]...

...the value attribute 'search me' is what is displayed on default page load.

If I focus on the text field and type into it, "Hello World!"

How can I see that new value?

I've tried the obvious [code]...

How can I pick up the new value on the fly? It must be possible, no?

JQuery :: Grab The Text Of All <a> Tags But Filter Out Duplicates?

Sep 10, 2011

My question is located here:[URL]... what I have is div 1 this div 1 has <a> tags appended to this div. It's a list of items the client selected to buy. so I have these <a> tags. I want to generate a invoice or a summary of the order and append the new <a> tags in a new div we will call this div 2.

for example lets say I have 5 apples at $1 each ordered and 3 oranges at $5 each for one order placed In div 2 I want to go to div 1 and grab the text name of the item and only grab the names once. No need to have multiple of the same item names. I will then create a new <a> tag and then append it to that div 2. Inside these <a> tag will be something like: Apple amount order 5 total $5.00 Orange amount order 3 total $15.00 Total amount due: $20.00 so in div 1 there be lots of <a> tags and you will see at least 3 apples ordered but it be listed as aseparateitem.

In the invoice or summary of the order I want to sum up the order. So I just want to let the client know your ordering 3 apples at a total of $5 for those apples. You ordered 3 oranges at a total of $15 which makes the bill to come out to be $20 dollars.

how can I grab from the <a> tag list only text that hasn't been grabbed yet. I don't want to display the word apple 3 times since there are 3 times that the client selected to order. How can jquery filter such requests. I just want to grab the text or names of the items. Then display that name once. if that name appears more then once in the div 1 then in div 2 you will say just the item name once but show how many of that item you ordered.

JQuery :: Faking A User's Click On An <a> Element OR Ajax-call - Firefox Addon To Readout The Facebook-privacysettings

Oct 5, 2011

I'm writing a firefox addon to readout the facebook-privacysettings of an user.

[url]

There are a lot of "Edit settings" which open a dialog like this:

The HTML code looks like this:

My solution idea was to fake the ajax call like this:

I got this parameter from Firebug, and i get the same answer as the "manual"-click. It's javascript code, beginning with "for...". however the dialog doesn't open, the DOM node isn't added and i get the alert "Error! Status = 200 OK"

So I just figured: why the comlicated way with ajax, can't I somehow fake the real manual click? If someone knows a way with ajax or faking the click?

Getting First Sentence From Wiki Article?

Jan 29, 2010

Does anyone know of an easy way, using javascript/jscript/jquery only, to get the first sentence of any Wikipedia article?

I've tried using ajax to grab all the html and then narrow it down using a couple of split() functions, but not every article is the same, so I don't think I can do it that way.

How To Make Sure An IFrame Is Referenced Before Pasting Html Into It

Jun 18, 2006

At the moment, if I don't specifically click into the iFrame (it is in
design mode) then when I paste the HTML it attaches itself to the main
document rather than in the iframe 'body'.

My JS function at the moment is simply:

function doTable(tabledata)
{
if(tabledata != '')
iHTMLeditor.document.selection.createRange().paste HTML(tabledata);
}

but I think I need an extra line above the iHTMLEditor (my iframe's ID) bit
to make sure it goes in there.
