#15004 — Grabbing words/text under mouse?

I want to be able to get word definitions to display when a user double 
clicks a word being displayed. The text is being loaded out of a mysql 
database and I am working with it in PHP.

I figured javascript is the only way I know to directly interact with 
the user and browser.

I tried enclosing each word with a div or href but not only does it take 
a long time to process but it really doesn't work with other formatting 
the text undergoes.

So is there a way to get the word/text that was under the mouse when it 
was double clicked?

Thanks
Mike

Yes.

The simplest way is not clientside javascript, though, 
just HTML and serverside scripting, possibly in javascript.

Try it, and we could help if you get stuck,
if you use serverside javascript that is, 
otherwise ask in the appropriate NG.

comp.lang.javascript ?
I have heard of serverside javascript but never really got into it.
How does one go about writing server side javascript? How would 
something server side know when a user clicks in the client?

.... This is for a online Bible and I hope to eventually link in 
Strong's Concordance to it so that readers could double click a word to 
get definitions/translations/etc..

Thanks
Mike

You will find javascript engines used in many other places than browsers.

Just type  the file.

on an ASP platform, define JS as the default and write between:


<% response.write('Hello world'); %>

or even shorthand:

<% = 'Hello world' %>

I prefer concordance with Hebrew or ECMA.

There are many uses of Javascript on the server.  ASP [1] has had it
for years.  Node.js [2] seems to be the latest darling of the web
developer community, although some prefer Narwhal [3].  But there are
far too many implementation to keep track of.

It wouldn't, not until after an HTTP request, the same as with any
other server-side language.

That's why they are called server and client.

The client initiates all actions, 
while the only duty of a server is to serve.

=================

<a href='/storeThis.asp?where=field1&value=23' 
target='myInvisibleIframe'>
Store 23 in field one</a>

<a href='/storeThis.asp?where=field2&value=stop' 
target='myInvisibleIframe'>
Store 'stop' in field two</a>

will bring the server javascript code into action defined by the serverside  
scripting, without any clientside scripting language used.

Beware of sql-injection with these examples, 
so write solid serverside code [and test for in-session].

I've used sites that do this and I find it very annoying. I double
click to select words and I triple click to select a paragraphs.
Usually I do this as a visual bookmark when scrolling, but sometimes
to cut&paste. 

If you want to include a glossary for difficult words, you can just use
<a> links with title text:

 <a title="section of a document that defines words">glossary</a>

Hovering over the word shows the title text. Style as desired.

It would not interfere if there was a definition mode that you need to 
enable first.

Not so.  If it is a link, use an `href' attribute.  If it is not a link, do 
not use an `a' element; use a `span' element or another inline-level element 
if it is better semantically.  All those have a `title' attribute.

However, be aware that the `title' attribute does not mean "tooltip"; it 
means "additional information" and does not prescribe a certain kind of 
display.  If you want a tooltip, use CSS; for example, my Accessible Pure 
CSS Tooltips, which can be complemented with scripting, as used on 
<http://PointedEars.de/es-matrix>.

A double click selects the clicked text and you can access the 
selection, see 
http://home.arcor.de/martin.honnen/javascript/2012/test2012071101.html 
for an example. You might need to cut off a trailing space included by 
most browsers it seems.

And the example tries to cater for both the window.getSelection 
supported with Mozilla, Opera, Chrome, and IE 9 as well as 
document.selection supported in older IE versions but I haven't tested 
with older IE versions.

For a documentation see https://developer.mozilla.org/en/DOM/Selection 
and http://msdn.microsoft.com/en-us/library/ie/ms535872%28v=vs.85%29.aspx

My <http://www.merlyn.demon.co.uk/js-props.htm> does that; press the
Enter button, then double-click a word in the new grey area - it will be
appended to the input line.  The actual code is in
<http://www.merlyn.demon.co.uk/inc-prop.js>; just remove what you do not
need.  Note : I give special treatment to all-digit "word"s.
