Readme
Angular directives, including or excluding HTML-elements, based on currently active Bootstrap grid: xs, sm, md, lg. Allowing for a reduction of watcherts.
- Bootstrap 3 grid class detection takes places via injecting Bootstrap 3 grid classes and testing them for visibility.
- Internally,
ng-if
is used. - Thus, as this directive combines the Bootstrap-css-grid and Angular-ng-if, it should be pretty solid.
Installation
npm i ng-if-bootstrap-grid --save
Usage
AngularJS
angular.module('myApp', [require('ng-if-bootstrap-grid').name]);
HTML
<h1 ng-if-bootstrap-grid="md,lg">md,lg</h1><!-- md and lg are or'ed -->
<h1 ng-if-bootstrap-grid="lg">lg</h1>
<h1 ng-if-bootstrap-grid="md">md</h1>
<h1 ng-if-bootstrap-grid="sm">sm</h1>
<h1 ng-if-bootstrap-grid="xs">xs</h1>
<h1 ng-if-not-bootstrap-grid="lg">not-lg</h1>
<h1 ng-if-not-bootstrap-grid="md">not-md</h1>
<h1 ng-if-not-bootstrap-grid="sm">not-sm</h1>
<h1 ng-if-not-bootstrap-grid="xs">not-xs</h1>
Details
Add the ng-if-bootstrap-grid
or ng-if-not-bootstrap-grid
attribute to any HTML-element that should be excluded or included, based on the currently active bootstrap grid class.
Works like ng-if
: the excluded elements (and their children) will not get rendered. Thus limiting the watcher count. The bootstrap classes (col-xs-*
) just hide elemens, but they still get rendered.
The attributes take the grid class as a parameter. More than one grid class can be set as parameter value, by separating them with commas or spaces.
TODO
The injection does not take place in the compile
function of the directive, as this (misteriously) breaks the code.
