I am using Jquery, php and html5. Either an input field or a textarea is used and for both i always run into the same problem: inserting emoticons / smileys: they won't. They only seem to want to add straight up text, nothing else.
I've googled and googled even tried to code something which adds the value of the key pressed to a div (and therefor have the potential to not insert :-) but insert a smiley instead), but that doesn't seem to be ideal.
Do any of you know how to do this properly and would like to show me how?
Really at a loss here....I would be very grateful for any help.
First of all - font letter is graphic object and smile picture is graphic object ))
Most simple way - just using font with smiles instead of regular font.
Take a look for http://www.fontspace.com/category/emotions, for example.

Using Javascript, I need to allow a user to double click a word on a page and retrieve the sentence that it appears in. Not just any sentence, but that specific one. I've toyed with retrieving all sentences that that word appears in and somehow choosing the correct sentence, so maybe that's an option.
I've scoured the web looking for this beast, and I've thought a lot about it. Some have recommended using Rangy but I haven't been able to find the functionality I'm looking for, or even functionality that would help me get where I need to be.
Any ideas?
You could turn your page into one or multiple read-only textareas, use clever CSS styling to mask it, then use the onselect event as described here: Detect selected text in a text area with javascript
Depends of course, how your page looks like and where it's used.
I've had a horrible problem that I've been wracking my brain for the past two days for, and have yet to come up with a solution. As such, I think this needs someone smarter than I to accomplish.
What I'm trying to build is a textbox that simulates that of Facebook's; essentially, the tagging function.
Now if you've used Facebook, you'll have noticed that Facebook allows you to tag people in a comment/post, simply by typing in their name and selecting from a dropdown list. The name of the person you've selected then appears in highlighted text in that very textarea. I've successfully managed to create and populate the dropdown list a combination of JQuery and AJAX, but the tagging process itself is the stumper.
Once a dropdown item has been selected (by Enter or clicking), the query text will be replaced with the tagged name. Now, it's difficult to see how one can give text in a textarea any kind of a highlight, so I've discovered (by inspecting elements in Google Chrome and deleting the textarea node) that the textarea itself is transparent, and there is a white div below "simulating" the text. Highlighted words are placed in a tag with custom CSS, which gives it that blue background. All of this I've found out myself, and I have successfully simulated this - but I can only do one tag.
Now I've investigated further and found an input type="hidden" element, of class "mentionsHidden". This input element has a value attribute, which dynamically populates itself based on the content of the textarea. So if I typed "ABC", the value of the element becomes "ABC". If I included a tag, say "hi [Rei]!" (where the name in [] is the tag), the value of the element becomes "hi #[member_id:Rei]!".
So I HAVE done my homework. But here comes the part I can't figure out.
I can't figure out how exactly to dynamically populate the hidden input element with the value of the textbox. It's obvious that the underlying div giving the blue tag background is populated from the input element. But the input element is giving me a headache.
You see, I can't do the following:
-I can't simply "copy" the entire value of the current textarea and "paste" it into the input element's value, because that would override any previously tagged people in the input element (after all, the textarea can only possess plaintext).
-Even though I CAN locate the current index of the caret (the flashing black line in the textarea that tells you where you're going to be typing into), that's only for the textarea. Index position 10 in the textarea and in the input element's value might be different things, because this way of "tagging" people will result in adding additional characters to the value String.
-I can't simply do a "replace" of the text I am intending to replace, because there might be other instances of that same text in other parts of the value String.
I know it's a very long and confusing post, but I do hope you get what I mean. I really need a solution and I don't want to use contenteditable, because it's only for HTML5 and some older browsers might not support it.
Yours,
Rei
I hope you were able to come up with, or find, a solution to your problem. Since there doesn't seem to be one here, i'd like to offer one for and anyone who might stumble upon this (as well as you if my assumption was incorrect).
You are going to need to maintain explicit locational data of each existing mention in the textarea in the order in which they appear. If, after a modification of the content in textarea, the position of a mention in it is changed, you will need to determine which appearance of its value, if any, will be used to represent it, and appropriately update the locational data of the mention.
With such a collection of data, it becomes trivial to construct the value of mentionsHidden, though the existence of such data makes the element unnecessary.
Mentionator is an existing, robust solution which takes this approach in providing the functionality you are trying to recreate. Considering it is well-structured, easy to follow, and copiously commented, it should be of use to you as either out-of-the box solution or reference material to cite as you roll out your own. It is maintained by yours truly :) .
I'm looking for a way to apply some formatting to a single-line text input field in JavaScript. It would work like this:
The user types in a formula, such as:
(7 + 3) ^ x
As the user types, my code would format it using colour to look like this:
I can do the necessary parsing but I don't know how to apply these styles to the user's text as they edit.
I've been struggling to find the right thing to Google for. My searches mostly lead me to full-blown text editors.
Is there such a component? If not, can I achieve this with a <input type="text"...> field?
Out of curiosity I built this: http://jsfiddle.net/hunter/npbDL/
This catches key strokes and inserts a span-wrapped character into an element. If the character maps to an item in the character-to-class collection it also gives that span the class specified.
It also handles enter and backspace.
You can probably take it from there...
I think the only way you can achieve the styling you want is by wrapping HTML tags around individual characters then styling the tags, and I don’t think you can do that inside an <input type="text">.
There is the widely-supported contenteditable attribute which makes most elements editable, but I’m not sure that it allows this either. If no-one else provides a better answer, you might want to view source on the last example here: http://www.hyperwrite.com/Articles/contenteditable.aspx
You can't format a text field with various colors. You might be able to use colors in WYSIWYG editors... or Flash.
I don't think you can change of individual characters in any <input> nor <textarea>. Look into source code of Etherpad for example - it uses similar system (not exactly the same - it highlights other stuff) and it might help you.
How can I do some manipulations with the text in a TextBox on resize in Adobe InDesign CS5?
The main goal is too split the last word on every row to achieve something like a custom hyphenation.
Is it possible using JavaScript (or ExtendScript?) ?
Thanks.
UPDATE
I've tried to describe my problem in comments
I need an example on ExtendScript, which would find textbox dimensions and hyphenate the text according to dimension and after I'd like to create an event on textbox resize, which would do the same thing after every resize.
You'll probably be able to write a script to do what you want, but the functionality is already built into InDesign.
If I understand your problem correctly it's InDesign does not hyphenate Armenian properly? You can insert manual hyphenationsin the text using the text tool and pressing 'Ctrl'+'-' where you want the hyphen in the text. Unfortunately you'll have to do that everytime you resize the box, because the words will move around - which is probably the problem you're having.
You can set the language in InDesign in the Character tab (shortcut is 'Ctrl'+'t') and upload custom dictionaries/word lists with rules specific to your language including rules for spelling and hyphenation. Unfortunately I couldn't find Armenian in my short search, but perhaps you're more lucky.

I have a little website where I would like to obfuscate some text to protected spoiling of users that accidentally read it untimely.
Much like the keywords on imdb were, where you have to rollover to reveal them.
I thought it would be a nice and interactive way to reveal the text if its marked.
Example:
How does a programmer express
h(is)|(er) love? Zl srryvatf sbe lbh
ner uneqpbqrq.
Now you would drag mark the obfuscated text much like you would get ready to copy it to your clipboard, and it should reveal.
Is there a way to do this? My current problem is a way to determine the current selection in javascript.
There is one tricky way I can think of with only CSS:
Use the same color text as the background color! Then when users highlight, the text is revealed. You would need to outline or draw attention to the part that they need to highlight to make it obvious.
Another way:
Stuff the rot13 into a readonly text input, and attach a select event with an AJAX call that decodes it. Will only work for smaller bits of spoiler text that fit in the input. You could try this with a textarea but it doesn't accept the readonly attribute (maybe doesn't matter).
There are many many other ways to do this (hide/show divs for example), but these are the closest/simplest ways I could think that match your requirement of selecting text to trigger the spoiler.
EDIT: With the background color solution, you would not want to encode the text, just make it "invisible" until it's highlighted. It's actually a pretty cheesy solution, and there are many others that are better, but the good part is that it is css only. Honestly I think forcing a complete highlight will be a pain for your users, just store the rot13 value in one place, the real value in another (hidden span maybe), and use js to swap them out on click or something. No need to actually process the decoding separately. You could probably do this with CSS alone and some smart :hover or :focus selectors.
EDIT2: For some reason it didn't occur to me that you can do rot13 decoding with javascript alone, I'm coming from the php world so now I feel pretty foolish. Sorry I didn't answer your question better, but hopefully some of this is useful. GL!
