mootools

I would like to programmaticaly determine the DPI of a user's display in order to show a web page at a precise number of units (centimeters/inches). I know it a weird request: it's for a visualization research project and it's kind of a control. We currently do it by having the user place a credit card to the screen and match a resizable div (via Mootools) to the real credit card, and voila we can get the DPI and display the page correctly. Can anyone think of a programmatic way to do this? Randolpho If you're doing this in javascript/mootools, CSS units are your friend. You can specify sizes

I have a fairly large codebase that depends on MooTools v1.11 and am about to convert to version 1.2. Since this is a pretty major overhaul, I've toyed with the idea of converting to jQuery. Anyone have advice on whether to update to jQuery or just stick

Are there any best practices or common solutions to adding support for "static" methods and variables to MooTools-generated classes? In particular, is there any solution that ensures that static initialization takes place before the instance initialize method is called? Caveat: Never used MooTools. I've used Prototype a fair bit, though, which has a similar Class system (MooTools is either "inspired by" or a fork of Prototype, depending on who you ask). Just add them as properties on the resulting "class": var MyClass = new Class(properties); MyClass.staticMethod = function() { // ... }; (The

Cross Platform if possible, how can I select classes in Javascript (but not Jquery please -MooTools is fine though-) on code that I can't add an ID? Specifically, I want to add the class "cf" on any li below: HTML <div class="itemRelated"> <ul> <li class="even"> <li class="odd"> <li class="even"> I tried to fiddle it but something is missing: Javascript var list, i; list = document.getElementsByClassName("even, odd"); for (i = 0; i < list.length; ++i) { list[index].setAttribute('class', 'cf'); } JSFiddle ps. This question phenomenally has possible duplicates , (another one ) but none of the

But I can't seem to find a Mootools equivalent of jQuery's toggle() function. What I'm trying to do is as follows: $('a#id').toggle( function() { $(this).set('html', 'new text'); }, function() { $(this).set('html', 'old text'); } ); How would I modify the above code for mootools? Thanks! 回答1: As far as I know that "toggle" on mootools doesn't exists. You could "implement" it, by this way for example: http://www.jsfiddle.net/steweb/rdvx8/ Is this what you'd like
