I'm currently trying to create a page for users to select two points from a range, using a slide control. The first point in the range is when an alert will be sent to the user, the second point is a max limit. What I would like to do is have the bar colored green from the 0 point to the first slider point, then orange between the two sliders, and lastly red from the second slider up to the other end of the bar.
Does anyone know of an easy was I can do this or of a slider control that can be skinned to do this?
I didnt manage to find a slider that did exactly what I was after. I ended up going with the JQuery UI slider as seen here. It's a very nice slider although it has its issues it was the simplest one I could find that was still a close match to my original specifications.
This seems to be what you want. See the Mootools documentation for details.

i am using the leaflet slider by[dwilhelm89][1], i'm letting it slide through days( i made each day a layer and added it to the slider) but i need to add a label(timeline) so that you can see where the slider will go, any idea how to do that? thanks
var sliderControl = L.control.sliderControl({ position: "topright", layer: layerk, range: true, follow:true,alwaysShowDate : true});
map.addControl(sliderControl);
sliderControl.startSlider();
this code is what i used to make the slider, any options or edits i can use? [1]: https://github.com/dwilhelm89/LeafletSlider
If you mean adding a scale with tick marks, the LeafletSlider doesn't seem to have any options for that. Though I don't have any suggestions for modifying or extending the LeafletSlider code, a couple other approaches spring to mind:
First, if you are only dealing with a few days, and you just need a few labels along the length of the slider, it may be possible to adapt one of the examples from the answers to this stackoverflow question. The top-voted answer in particular looks promising, as it is probably the simplest solution.
[EDIT: After looking into the Leaflet Slider code a bit more, I realised that it does not actually filter the data by the quantity in the time field. It simply steps from one feature to the next as you slide it (i.e. an interval of two seconds is treated the same as an interval of two years). Thus, this first method actually will not work with LeafletSlider unless the time field is monotonically increasing, or very nearly so, from one feature to the next.]
Second, you could adapt another non-Leaflet-specific slider to do the job, like the jQRangeSlider, which has some pretty decent options for scales. Here is an example of that approach:
http://fiddle.jshell.net/nathansnider/p850sr8y/
In addition to the slider itself, it consists of a custom control, which allows you to place the slider on the map, and a function to filter the data, which is called each time the slider is moved. If you want further details on this, I'd be happy to elaborate.
I was curious about the possibilities of animating features in OpenLayers3.
I'm very aware of the examples presented here
http://openlayers.org/en/v3.0.0/examples/animation.html and here
https://gis.stackexchange.com/questions/26546/openlayers-animation-examples-and-algorithms
However, the official examples for OL3 don't quite fit my needs.
Let's assume that I have a layer (geojson for instance) that has a "time" column with lots and lots of time values.
I'd like to implement something like a slider that adds/removes features (or changes their style) depending on the user's actions.
The thing is that there are some APIs that might be able to do that, but they seem to be outdated (code examples were still working with ol2).
Do you have any suggestions on how to build a simple animation slider with OL3?
EDIT: It doesn't necessarily have to be proper animation. A possibility that came to my mind is changing the style of a layer whenever the slider is moved. Still no clue though on how to realise that.
This image illustrates what I have in mind:
EDIT: My current approach is to have a slider, that triggers code everytime it is moved. I somehow try do change the layer style dynamically, but I still haven't gotten a viable result.
Ok. I've come up with a solution myself. It's not really a full-fledged animation, but it works for me.
Basically what I do is that I load a wfs-layer to my map.
Now, here is the trick:
When I do that, I simply sort the time-values of the features one by one and add every feature with the time value of 1 to one layer, every feature with a time value of 2 to another and so and so forth.
This basically does the trick. The rest is simple.
Next step is that I implement a slider that ranges from 1 (the lowest time value) to whatever the highest time value is. Everytime the slider is moved it triggers an event that finds out to which time value the slider is set to and then adds/removes the corresponding layers.
So, if the slider is set to 5. It will add every layer from 1 to 5 to the map and remove every other layer. Again, this is not really an animation, but it does work in my case.
If anyone comes up with another possible solution, please post it here. I'd appreciate it.
(Btw, this is what my solution looks like in action:)
EDIT: I can now also confirm that it is possible to build "proper" animations with this approach. I simply built a js-function that includes multiple "setTimeout"s to time when a layer is added and added a play button that triggers this function. This amounts to an animation that visualises the growth from t=1 to tmax.
I'm struggling to build a simple animation based on those old clocks with flip-down numbers. I added an image below copied from a freebie PSD found on Premium Pixels:
The biggest problem I'm running into is building a "flipping" animation using jQuery all in HTML/CSS/JavaScript. The only tutorial I've found is from this net tuts+ article which actually uses images. It splits the top and bottom half of the clock into two different image sets and replaces them for each second that passes by...
This method isn't realistic in a website since it provides no actual context for readers. I'd prefer to have the numbers hard coded into HTML and perform the flipping animation solely through jQuery - preferably no images except background ticker boxes. Or to put it another way the numbers are coded into HTML but the clock itself is a series of rolodex-style bg images.
I hope I've explained this well enough.. I've been struggling on this for a few days and I honestly have no idea how to approach this script. Maybe by splitting the top and bottom halves into different divs, then change the internal numbers for each second that passes? I'm fairly well-off in jQuery but I am weak on animations.
Thanks in advance for any support!
I think I would attempt to do something where the text is duplicated for the top and bottom. Then using images and css to only display each half appropriately.
The next step would be creating the illusion that the text is flipping with the image. I am not sure how you want to do that. I think it is a matter of sizing and speed. The sizing of the text in relation to the image and the speed at which it flips from the top of bottom.
The final part of the animation is having the top half ready with the next number and the bottom half queue up on completion.
I don't have any actual code that will help, but I hope this concept is something that will work out.
Is there a JS/jQuery widget that would allow me to display a simple legend that contains for example a small colored rectanlge and a text label next to it?
In this specific case the legend would show meanings behind different color codes in an inline jQuery UI datepicker widget, which would be customized to enable multiple selections by a user and showing different colors for specific days.
In fact, the thing that I need would look exactly like the list of SO sites at the footer of this page (but ideally listed vertically next to the picker). So if there is no ready-made solution I guess I'll try and look at this page source.
You have to hand it to the StackOverflow crew. Their method for creating the legends is pretty clever. Basically, they use the character ■ (ASCII 254) in place of any image or div. They insert it in a span, which is styled with a font size and color property. Next to it is a styled anchor tag. Rinse and repeat.
What is particularly clever about it is that it all fits inline in a div and lines up on the baseline! Let me say that again: it lines up on the baseline! So there is no disparity in image offsets, etc. A tip of the hat to the UI engineer who made it that simple. Thanks for calling my attention to that, or I probably never would have looked and learned.
EDIT: ASCII 254 is incorrect. The actual value yielded by "■".charCodeAt(0) is 9632 and is probably some flavor of Unicode. Same look and shape, but different value.
I have a 2 column table in a database 1,000 rows long(All integer data).
The display will allow for the user to delete a certain range of data from the table.
What I am looking for is a creative way to display all the data so the user can get to different parts of it really fast. Maybe displaying different chunks at once, represent with bar graphs or zooming the scope in/out would be really cool.
Any ideas,suggestions, examples at all are appreciated. Please just throw them out here for brainstorming.
Note: I am limited to JS, xml, html and C
Thanks!
By mouse scroll resize the text.
Add drag'n'drop for moving text block.
Example: user resizes it to a smaller chunk by mouse weal then moves it by using drag'n'drop.
It is possible to implement such thing with jQuery/JavaScript
Use a double slider with a min and max display range. Here is an example of one based on MooTools. Moving the slider controls will adjust which range of values are displayed in the table.
Could implement something that functions like google maps where you can easily zoom in and out and set points wherever you need that stay when you change elevation.
you can format the html with <h1>, <h2>, <h3> and <p> tags, and use jquery to collapse the paragraphs, leaving headings of major sections.
I did this with documentation i was working on and it worked out great.
I'm a fan of the JavaScript bookmarklet demoed in this video: http://www.youtube.com/watch?v=GPZ8YNgyl_I
The bookmarklet itself is available here: http://t_trace.wed.macserver.jp/overview.html
If you have used WinMerge, you could develop something like the location pane in the left that shows a full preview of the changes in files. It can be used to navigate very fast
Here's a screenshot. (Image too large to inline it here)
Assuming the integer data come in ranges, a common approach is to show how much data there is in each range as a horizontal bar. You click the range to zoom in, until you see the actual data, or click the X to delete.
ID Range
[X] 1-1000 xxxxxxxxxxxxxxxxxxxxx
[X] 1001-2000 xxxxxxxxx
[X] 2001-3000 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
A further refinement is to use colour on the horizontal bars to show data density. For instance red = lots of data, yellow = less
