#jQuery UI

Earlier today, I was adding a “slider” UI element to a project that was using Twitter Bootstrap as well as jQuery UI. Although they weren’t designed to work together, the two projects generally stay out of each other’s way since their CSS classes are namespaced pretty well.

Since jQuery UI was already loaded I naturally decided to just use the jQuery UI slider control to power the slider. One of the limitations with the jQuery UI slider is that it has no native way to show the current slider value over the slider handle, as a developer you have to display that number somewhere. Fortunately, the control has the event hooks neccesary to make this happen – specifically the slide event which is triggered everytime the slider is moved.

With Bootstrap also loaded, I decided to try and use the tooltip plugin to dynamically display the current value of the slider above the handle. Getting the initual tooltip setup was pretty straightforward. Check it out here.

But the issue is that even with the “slide” event, the Bootstrap tooltip plugin has no exposed method to force a reposition. The only way to get a tooltip to reposition itself is to hide it and then show it again. Obviously, that’s less than ideal since you get a noticible “jump” as the tooltip is hid and then shown again.

With this issue in mind, I decided to take a look at how the Tooltip plugin actually does the positioning. It turns out it’s really simple, the relevant code is on GitHub. Ok, so its easy to reposition them but how do you get the “right” tooltip div incase you have multiple sliders? Looking through the code, the Tooltip plugin actually uses the jQuery.data() function to store config options and additionally stores a reference to the correct div there. Getting a handle to the correct div is as easy as $(“#slider .ui-slider-handle:first”).data(“tooltip”).$tip

Looking at the actual plugin code, it’s simple enough to just copy that out and use it to reposition the tooltips. Check it out in action at http://jsfiddle.net/cqVPM/7/

Anyway, let me know if you run into any issues in the comments.

I was looking around earlier for a jQuery plugin to allow me to use jQuery UI’s dialog() widget to popup a confirm dialog. Didn’t have any luck finding one so I whipped something up. It’s not pretty but it works. You could even go as far as to overload window.confirm() but thats probably a bad idea.

Wow its been awhile!

We’ve been insanely busy over the last month or so. We launched Setfive Ventures and are anxiously anticipating the launch of both WeGov and OmniStrat in the immediate future. There are also a handful of internal project that should be rolling out before Christmas. Get Excited.

Anyway, the jQuery UI Dialog class is pretty sweet. Basically, it provides a class to display a modal dialog box from a regular old DOM element (a div, span, or whatever.)

One of the thing that isn’t explained well (or at all?) in the documentation is that you can create a dialog with on the fly HTML! I found this out after posting on the Google Group asking why this feature didn’t exist (it does. Ashish fail.)

So if you want to create a dialog with on the fly HTML all you need to do is:

$("<p>Hello World!</p>").dialog();

Pretty sweet.
