I have been using nagios + pnp4nagios for a while and am happy with the images rrdtool creates. My current task is to create a panel that has some statistics generated by nagios and after a while the statistics change. I'm looking for something like that:
But also able to switch screens automatically. I do know that I can make a timed javascript function that switches the layout after a determined time, but I also want to add effects and other stuff to the picture. Any good javascript library that has it?
such effects can be achieved easily with most javascript libraries. I like jQuery quite well. See the examples in link text for inspiration

I am developing a simple website for a client using Rails and I want to give them an easy way to create and manage their top navigation menu. Wordpress has a great tool (see example below) for this but I haven't found anything like it that is generally available.
So far I am thinking that Jquery Sortable would be the best place to start but to make it handle nested data (like trees), adding and removing elements, and add rules such as limiting the depth of nested elements seems like a lot of work.
How have you guys gone about solving this problem?
Have you tried this
You can initialize like
$(function () {
$("ol").sortable()
})
It also supports animation.

I've built my mobile site using the jQuery Mobile UI but I now realize that I need some functionality to be different between it and my desktop site (datepicker dates should be longer on the desktop site, etc).
I've looked into Modernizr and matchMedia to help me load separate js files but I can't figure out a nice way for it to work responsively. Modernizr only works (unless I missed something in the doc) on the initial load and I'm having problems with matchMedia executing multiple times as it crosses the min/max-width threshold. It works sometimes but the trouble is in adding/removing the separate js files. On top of that (but not a huge issue - I don't think), Chrome fires off an error when loading scripts into the DOM from another script.
Would the best thing be to write one js file and then add a listener such as $.mobile.media("screen and (min-width: XXXpx)") to the body's width, changing my needed values?
I may be making this too hard for myself, or missing something obvious because I'm trying to keep HTTP requests and site size as small as possible, but I can't figure out a good solution for this.
Thank you!
Lightning Round Bonus Question: Is it good practice/proper to keep all of the jQuery Mobile styling (data-role data-id data-theme) after switching to the desktop site? It looks awfully .. awful for someone only viewing it on a larger screen.
IMHO, the best approach would be to introduce a couple of flags in your javascript, like "isMobile", "isTablet" or "isDesktop", that would be set within a method attached to the "pageinit" event of your webapp. Later on, you could check that flags to act accordingly with the proper version in the specific parts of your code.
The way you can check that flags depends on your architecture. In the project I am working right now, I extract that information from a class attached by the back-end on the body of the page, but that's because we have that info. You could try to use a library like Harvey to observe the media-queries that would be trigger, and set the flags accordingly. I don't think that your options ends here, but I am afraid I can't help you more!
I am looking to create a generic config pane for a grease monkey plugin. I was wondering if there exists a lib to make this easier?
I am looking for some tool where you might give it some name/value pairs and it will generate a nice looking UI.
I think ive seen this somewhere but forgot the search terms.
Maybe you can use jQuery UI lib for building pane. Lib is full of easy-to-use visual components.
Given how simple you seem to want it, why not just hand-write some HTML and CSS and throw that up on the page? It's very easy to show a simple configuration window and takes very little effort to make it look presentable.
If you want it to look nice, jQuery UI. You could also try Cappuccino, but the more library you layer on, the clumsier it'll get.
For a simple layout, just use tables. Taboo, yes, but effective... and it IS just a configuration screen.
Ok on meebo.com there is instant messages that when you click at the top you can move around i wanna make something like that?
So how do I make Movable forms in JS?
I recommend the jQuery UI plugin called Draggable.
You first need to create your form. Your form will most likely be a div (with solid color or image for the background). Within the div, you have all your form content. The div will also need to be position absolutely (i.e. style="position:absolute")
The JavaScript is fairly straight forward; however, I would personally use something like jQuery to do the work. I'm not sure how familiar with JavaScript you are, but even for an advanced user, using something like jQuery just makes sense. There is a library of tons of already built forms etc with great instructions on how to use them. Let me know if you need more info on how to use a library like jQuery (you can find it here:
http://jquery.com/
You can see all the plugins here:
http://plugins.jquery.com/ (look at 'windows and overlays' - lots of them!)
Click on one that looks interesting, and click on 'demonstration' to see if you like it. For example, the third link down - (mb)ConteinersPlus, a jQuery component for fully customizable and featured container layout (DIV box model) - would let you do this (with almost no work on your end)
http://pupunzi.com/ (this is the example link)
Obviously, if you want to learn how to script it by hand, let me know.
What I want to achieve is as follows:
For example, there is a symbol which represents a table on a web page, a user can drag this element to any place on the web page, when the user looses the cursor, a dialogue box will pop up to ask the user to input values of attributes, for example,the number of columns, the number of rows, after the input, the corresponding table will come out at the place where the user chose. Of course, the symbol which represents a table is still at the original place. It is like a web version of dreamweaver. How to do this with Javascript?
If your question is how to start researching this feature I'd start with:
JQuery to get started with fancy yet easy javascript functionality
JQuery UI: Draggable, Dialog, etc
To actually develop the feature, if you don't know where to start, start small. Create a very basic web page with maybe just an icon and a button and then write some javascript to do something minor like display a dialog and show the result. Slowly start adding things like dragging something around, etc.
The JQuery UI stuff has lots of demos that you can start out with as a base to start customizing.
Warning: The first time I hit the JQuery UI Demos page I wasted at least a couple of days playing with all their cool stuff. It's so easy because the source is right there and you can also see it working in the browser on the demo page.
Did you look at the jQuery UI demonstration pages? The simple photo manager demo contains all the major pieces you'll need: Dragging an item, handling the drop event, doing something custom on drop. The revert demo may also be of interest
Begin by defining the requirements of your project. Break it down into smaller tasks and milestones. Then some learning and research on what javascript and frameworks like jquery can provide. Also check for existing solutions or components that you may be able to use and reduce your development efforts.
