# selector-observer

Observe newly added and removed DOM nodes matching a given selector. This is especially useful for applying specific calls, e.g. Plugin calls, to further added DOM nodes.

## API

```js

  element.observeSelector(selector, onAdded, onRemoved);

```

or

```js

  // If you use browserify, require selector-observer:

  // var SelectorObserver = require('selector-observer');

  

  var observer = new SelectorObserver(target, selector, onAdded, onRemoved);

  observer.observe();

  

  //stop observing

  observer.disconnect();

```

## Example

```js

document.getElementById('some-id').observeSelector('div.draggable', function() {

  new Draggable(this)

})

```

## jQuery / Zepto.js

I have removed the jQuery / Zepto.js dependency in `1.0.0`. However, `selector-observer` is still compatible to both frameworks; a `.observe()` method can be added as follows:

```js

// usage $(targetSelector).observe(selector, onAdded, onRemoved)

$.fn.observe = function(selector, onAdded, onRemoved) {

  this[0].observeSelector(selector, onAdded, onRemoved)

  return this

}

```
