There are some situations where `dom-autoscroller` might be doing what it does, but even though the mouse cursor moves relative to the scroll position `mousemove` events do not get fired. When you set `syncMove` to true that allows `mousemove` events with fresh coordinates to be fired for some other source that might need those events. 14 | 15 | For now the option `syncMove` is set to false. This is for experimental purposes, and because this functionality is likely to be buggy. `touchmove` syncing is also planned, but it's best if the integration of move syncing be taken slow. Please leave plenty of issues to help integrate `syncMove`, and `mousemove` dispatch into `dom-autoscroller`. 16 | 17 | Once movement sync is fully integrated into `dom-autoscroller` the `syncMove` option might be set to default true, or removed entirely. It depends on how things work out down the line. 18 | 19 | Big Announcement! 20 | ----------------- 21 | 22 | Version 2 of dom-autoscroller is out. You can upgrade to version 2. 23 | 24 | Here are the differences. 25 | 26 | - **pixels option removed.** 27 | - maxSpeed option added. 28 | - Slightly different algorithm for scrolling 29 | - Scrolling speed changes dynamically based on distance from element edge 30 | - Compatibility with [rollup](https://github.com/rollup/rollup). 31 | 32 | Scrolling in dom-autoscroller is now much smoother. So you should upgrade to version 2. 33 | 34 | Install 35 | ------- 36 | 37 | **NPM** 38 | 39 | `npm install --save dom-autoscroller` 40 | 41 | **BOWER** 42 | 43 | `bower install --save dom-autoscroller` 44 | 45 | Then use browserify, webpack, or [rollup](https://github.com/rollup/rollup) to build your script. 46 | 47 | Or Download one of these files from the Github repo: 48 | 49 | - *dist/dom-autoscroller.js* 50 | - *dist/dom-autoscroller.min.js* 51 | 52 | If you use one of these prepackaged files the global name is **autoScroll**. 53 | 54 | Demo 55 | --- 56 | 57 | [jsfiddle Demo of dom-autoscroller](http://jsfiddle.net/gh/get/library/pure/hollowdoor/dom_autoscroller_demo/tree/master/Demo) 58 | 59 | 60 | Usage 61 | ----- 62 | 63 | This example uses [link-css](https://www.npmjs.com/package/link-css), and [dragula](https://www.npmjs.com/package/dragula). 64 | 65 | ```javascript 66 | require('link-css')('../node_modules/dragula/dist/dragula.min.css'); 67 | var dragula = require('dragula'), 68 | autoScroll = require('dom-autoscroller'); 69 | 70 | 71 | var drake = dragula([document.querySelector('#list'), document.querySelector('#hlist')]); 72 | var scroll = autoScroll([ 73 | document.querySelector('#list-container'), 74 | document.querySelector('#container2') 75 | ],{ 76 | margin: 20, 77 | maxSpeed: 5, 78 | scrollWhenOutside: true, 79 | autoScroll: function(){ 80 | //Only scroll when the pointer is down, and there is a child being dragged. 81 | return this.down && drake.dragging; 82 | } 83 | }); 84 | ``` 85 | 86 | Keep In Mind 87 | ------------ 88 | 89 | `dom-autoscroller` exploits the simplicity of the single parent, to child relationship. A scrolling element with more than one children will likely not work well with `dom-autoscroller`. 90 | 91 | For clarity here is a more complete example: 92 | 93 | ```html 94 | 95 | 96 | 97 | Drag test 98 | 106 | 107 | 108 |

148 | 168 | 169 | 170 | ``` 171 | 172 | If you look at the last example notice the containers have only one child, and that they're different from the containers used by *dragula*. In theory multiple children could work with `dom-autoscroller`, but the children scrolling might interfere with the workings of the library *dragula*. 173 | 174 | 175 | Auto Scroller API 176 | ----------------- 177 | 178 | ### autoScroll(element|elements, options) -> instance 179 | 180 | Create an auto scroller on an **element**, or and **array of elements**. 181 | 182 | **The element should have only one child element to work consistently.** 183 | 184 | #### options.margin = Integer 185 | 186 | An inner area to detect when the pointer is close to the edge. 187 | 188 | #### options.autoScroll = Function 189 | 190 | A callback function used to determine if the element should scroll, or when the element should scroll. 191 | 192 | Return a boolean value from this function to allow scrolling. 193 | 194 | #### options.maxSpeed = Integer 195 | 196 | `maxSpeed` defaults to 4. 197 | 198 | Speed effects in dom-autoscroller: 199 | 200 | 1. Speed adjusts dynamically depending on how close to the edge your pointer is. 201 | 2. Speed is pixels per frame. 202 | 203 | `maxSpeed` limits pixels per frame. 204 | 205 | #### options.pixels = Integer 206 | 207 | **removed in version 2** 208 | 209 | Set how many pixels per second you want to scroll during the auto scrolling action. More is smoother. 210 | 211 | Speed was **pixels/second** in version 1, and in version 2 speed is **pixels/frame**. 212 | 213 | #### options.scrollWhenOutside = Boolean 214 | 215 | Whther or not it should continue to scroll when the pointer is outside the container. Defaults to **false**. 216 | 217 | Auto Scroller Properties 218 | ------------------------ 219 | 220 | ### down = Boolean 221 | 222 | Is the pointer down? 223 | 224 | ### scrolling = Boolean 225 | 226 | Is one of the elements scrolling? 227 | 228 | ### point = Object 229 | 230 | **This reference no longer exists.** 231 | 232 | A reference to the [pointer](https://github.com/hollowdoor/pointer_point) object. 233 | 234 | Auto Scroller Methods 235 | --------------------- 236 | 237 | ### autoScroll 238 | 239 | The function you set in the constructor options for `options.autoScroll`. 240 | 241 | ### destroy(forceCleanAnimation) 242 | 243 | Remove all event listeners needed to be able to track the pointer. If destroy Auto Scroller meanwhile scrolling then just call `.destroy(true)` to force to stop scrolling animation. Call `.destroy()` and `.destroy(false)` is the same behaviours. 244 | 245 | Undocumented methods 246 | -------------------- 247 | 248 | There are undocumented methods in version 2. 249 | 250 | These are: 251 | 252 | 1. add() 253 | 2. remove() 254 | 255 | These methods add, or remove elements from dom-autoscroller. 256 | 257 | Why are these considered undocumented even though there here in the document? :) 258 | 259 | `add`, and `remove` are incomplete, and there is no detailed explanation. Use these methods at your own risk. 260 | 261 | About 262 | ----- 263 | 264 | There are tons of reasons to have auto scrolling. The main one being sometimes a finger can't reach the mouse wheel comfortably. `dom-autoscroller` is a comfort module. 265 | 266 | This is also a nice small module to do this kind of thing when auto scrolling is all you need. 267 | -------------------------------------------------------------------------------- /dist/dom-autoscroller.min.js:
