angular-resizable
A directive for creating resizable containers.
Why?
All other resizable directive concepts I came across include layout logic in the directive. I wanted a directive that only handled the resize logic. This way, the layout logic is quarantined to the CSS.
Usage
npm install angular-resizableorbower install angular-resizableor clone/download this repo- Include
angular-resizable.min.jsin your project. - Include
angular-resizable.min.cssin your project as well (this provides default styling for the resize handles). - Then include the module in your app:
angular.module('app', ['angularResizable']) - Use it:
<section resizable r-directions="['bottom', 'right']" r-flex="true">
Include any sides you want to be resizable in an array inside r-directions. Accepts 'top','right','bottom', and 'left'. You can style the handles however you want. Just override the styles in the css in your own stylesheet.
Options
| Attributes | Default | Accepts | Description |
|---|---|---|---|
| rDirections | ['right'] | ['top', 'right', 'bottom', 'left',] | Determines which sides of the element are resizable. |
| rFlex | false | boolean | Set as true if you are using flexbox. See this codepen. |
| rCenteredX | false | boolean | If set as true, the velocity of horizontal resizing will be doubled. |
| rCenteredY | false | boolean | If set as true, the velocity of vertical resizing will be doubled. |
| rWidth | false | integer or $scope variable | If set, the resizable element will be rendered with a predefined width relative to this value in pixels and a watcher will be set on the 'rWidth' attribute. See this codepen. |
| rHeight | false | integer or $scope variable | If set, the resizable element will be rendered with a predefined height relative to this value in pixels and a watcher will be set on the 'rHeight' attribute. See this codepen. |
| rGrabber | <span></span> |
string | Defines custom inner html for the grabber. |
| rNoThrottle | false | boolean | Disables angular-resizable.resizing throttling (see events section below). |
Events
For an example using the events, see this codepen.
angular-resizable.resizeStart
This event is emitted at the beginning of a resize with the following info object:
info.width: The width of the directive at time of resize start. Will be false if resizing verticallyinfo.height: The height of the directive at time of resize start. Will be false if resizing horizontallyinfo.id: The id of the directive. Will be false if there is no id set.info.evt: original mouse event object
angular-resizable.resizing
Called repeatedly while the mouse is being moved. By default, only calls once every 100ms to keep CPU usage low. For smooth resizing, use the rNoThrottle attribute. This event is emitted during the resizing of the element with the following object as an argument:
info.width: The width of the directive at time of resize end. Will be false if resizing verticallyinfo.height: The height of the directive at time of resize end. Will be false if resizing horizontallyinfo.id: The id of the directive. Will be false if there is no id set.info.evt: original mouse event object
angular-resizable.resizeEnd
This event is emitted at the end of a resize with the following object as an argument:
info.width: The width of the directive at time of resize end. Will be false if resizing verticallyinfo.height: The height of the directive at time of resize end. Will be false if resizing horizontallyinfo.id: The id of the directive. Will be false if there is no id set.info.evt: original mouse event object
