range

I'll try to make this clear. I need to select a specific row and one row previous relative from that selected row and one row next relative from that selected row without using id's. Is this possible? Previous and next one, in short. The reason why I can't (maybe I just don't know how) use id's, is because they are not in sequential order. They have gaps as you can see from this rather immature and random example. TABLE <-the name of the table +----+----------------------+-------+ | id | name | value | +----+----------------------+-------+ | 1 | some_name | asf | +----+----------------------+-

I'm trying to get a live output from a HTML5 input range slider into a javascript variable. Right now, I'm using <input type="range" id="rangevalue" onchange="arduino()"> The way I have it working is doing what I want, but it's not "live." I want to have it so while you're dragging the slider, it updates the variable, and not only once you let go. For example: when I'm dragging the slider from 1 to 5, I want the variable to update while I'm dragging, so it will update with 1,2,3,4,5 and not only jump from 1 to 5 once I release the slider. Is it possible to do such a thing? Any recommendations?

I'd like to create a range slider that has a div element follow the range thumb. This div element would contain the current value of the range input. How would I go about doing something like this? I've looked into styling the slider but don't know how I could add an actual element onto the thumb. It would look something like this, excuse my terrible drawing abilities: Edit: The following div should update while slider is being dragged. UPDATE: I got a pretty good prototype going but cant seem to get it to follow the slider perfectly. It gets off center by a few pixels depending on where it is

Possible Duplicate: Does an open-ended interval implementation exist for Java? i have an int variable and i'd like to check if it's value is in an interval [a,b]. I know it's a simple matter of using x>=a and x<=b or implementing a simple method which can do this, but i'd like to know if there is something already done. Searched in Math class, but i wasn't able to find one. It's not that important and not that big of an issue, but i'm curious if there is something like this, so i can use it instead of implementing my own :) In all my coding i haven't come across a method like this. Maybe one

Let's say I have a set of contenteditable="true" divs. <div id="0" contenteditable="true"></div> <div id="1" contenteditable..></div> <div...etc></div> I can't have one div, multiple divs is a must. How could I highlight the content of more than one div? Using ranges? Anything else? The answer is that it depends on the browser. See this example for a test of two methods using Ranges. The first attempts to create a Range per editable <div> and add all of them to the selection. The second attempts to create a single Range encompassing the contents of two editable <div> s. Results: In all

at the moment I have some troubles writing an abstraction layer for Mozilla and Webkit based browsers for using the DOM-range object (getting and processing user selections). I have also tried to have a look at frameworks like Rangy but this seems far to complex for my task (I have no idea where exactly in the code to find the information I need. If someone could give me a hint, I would be grateful!). What I want is simply this: get back the reference to the text node the selection starts in and its offset get back the reference to the text node the selection ends in and its offset So far my
