Which Javascript library?

[quote author="marlar" date="1197584757"]Thanks, jQuery does indeed look very good.

WolfgangA: I don't mean autocomplete. It's not going to work on text being typed, it's plain html where some words has a little popup (context) menu with alternatives to the word in question. As such it could be any popup menu combined with ajax (the highlighted word will be updated) and I have found a couple of them on dynamicdrive.com. But I would very much prefer not to mix different libraries, that is why I am searching for such a feature in, say, jQuery.[/quote]

If it is really just a popup that should show up while hovering over plain html text, than you might want to have a look at the Ext.QuickTips class, when considering EXT.

From the Ext 2.0 Docs:

Provides attractive and customizable tooltips for any element. The QuickTips singleton is used to configure and manage tooltips globally for multiple elements in a generic manner. To create individual tooltips with maximum customizability, you should consider either Ext.Tip or Ext.ToolTip.

Here is an example showing how some of these config options could be used:

Code:

// Init the singleton.  Any tag-based quick tips will start working.
Ext.QuickTips.init();

// Apply a set of config properties to the singleton
Ext.apply(Ext.QuickTips.getQuickTip(), {
    maxWidth: 200,
    minWidth: 100,
    showDelay: 50,
    trackMouse: true
});

// Manually register a quick tip for a specific element
q.register({
    target: 'my-div',
    title: 'My Tooltip',
    text: 'This tooltip was added in code',
    width: 100,
    dismissDelay: 20
});

Here is an example of configuring an HTML element to display a tooltip from markup:

Code:

// Add a quick tip to an HTML button
<input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100"
     ext:qtip="This is a quick tip from markup!"></input>

If you need more flexibility, you can use Ext.Tip or Ext.ToolTip instead.
(Note: QuickTip is subclassed from ToolTip)
