slider

问题 Is it possible to make a sliderInput that shows the values in decreasing order (from left to right; eg. 5 4 3 2 1)? runApp( list( ui = fluidPage( sliderInput("test","", min=5, max=1, value = 3, step=1) ), server = function(input,output) {} ) ) 回答1: EDIT 2017-10-13: This function is now available in package shinyWidgets (with a different name : sliderTextInput() ). Hi you can write your own slider function like this (it's a little dirty...) : sliderValues <- function (inputId, label, values,

问题 I've tried a veriety of jQuery plugins recently and I keep getting this error … (source: shaunbellis.co.uk) … regardless of what plugin I try to use. I've checked the links to the JS files which are all there and working fine. I'm using Drupal if that makes any difference. I've run the plugins away from the main site to demonstrate that they are working and that I am doing things right with 100% success. Any ideas? Update: My jQuery file called in the footer: $(document).ready(function() { $(

问题 I need to make Bootstrap 3.0 Carousel to display a slide of thumbnails. How can I do this?

问题 I am trying to write a small bit of code that interactively deletes selected slices in an image series using matplotlib. I have created a button 'delete' which stores a number of indices to be deleted when the button 'update' is selected. However, I am currently unable to reset the range of my slider widget, i.e. removing the number of deleted slices from valmax. What is the pythonic solution to this problem? Here is my code: import dicom import numpy as np import matplotlib.pyplot as plt

问题 I need to make a slider. I have content (which should shift horizontally) and two buttons - "right" and "left". If you press the button and hold it, the content starts to move (in the appropriate direction). If you not hold the button, then the movement stops. This behavior copies the behavior of a usual window scrollbar. I wrote some code: var animateTime = 1, offsetStep = 5; //event handling for buttons "left", "right" $('.bttR, .bttL') .mousedown(function() { scrollContent.data('loop',

问题 I'm using matplotlib sliders, similar to this demo. The sliders currently use 2 decimal places and 'feel' quite continuous (though they have to be discrete on some level). Can I decide on what level they are discrete? Integer steps? 0.1-sized steps? 0.5? My google-fu failed me. 回答1: If you just want integer values, just pass in an approriate valfmt when you create the slider (e.g. valfmt='%0.0f' ) However, if you want non-integer invervals, you'll need to manually set the text value each time

问题 How can I style a Slider control for WPF in a way like this figure: Any similar samples would be appreciated.

问题 I have a jQuery slider on my site and the code going to the next slide is in a function called nextImage. I used setInterval to run my function on a timer, and it does exactly what I want: it runs my slides on a timer. BUT, if I go to the site in Chrome, switch to another tab and return, the slider runs through the slides continuously until it 'catches up'. Does anyone know of a way to fix this. The following is my code. setInterval(function() { nextImage(); }, 8000); 回答1: How to detect when

问题 I'm using coda slider to slide a number of embedded Vimeo videos into view and I now need each video to pause when a link to another slide has been clicked. I'm embedding videos using an iframe and found this code which does the trick: http://jsfiddle.net/ASa2K/4/ My code is different though and I just don't know where the following pause script goes in my Coda slider JS file: $("iframe").each(function() { this.contentWindow.postMessage('{ "method": "pause" }', "http://player.vimeo.com"); });

问题 I have a databinding problem in WPF. I would like to "customise" a slider in a way that the thumb grows when you move the slider to the right and the thumb shrinks when you move the slider to the left. So I edited the template for the slider and changed the look of the slider so the slider looks like I want it to. But now I have to bind the height of the thumb to the value of the slider but I do not know how that works. I did some simple data binding things but I cannot figure out how I can
