SentinelJS is a tiny JS library that lets you detect new DOM nodes using CSS selectors (682 bytes).
SentinelJS is a tiny JS library that makes it easier to set up watch functions that will notify you anytime a new DOM node is added that satisfies a CSS selector rule.
<!doctype html>
<html>
<head>
<script src="//cdn.rawgit.com/muicss/sentineljs/0.0.1/dist/sentinel.min.js"></script>
<script>
// use the `sentinel` global object
sentinel.on('.my-div', function(el) {
el.innerHTML = 'The sentinel is always watching.';
});
// add a new div to the DOM
function addDiv() {
var newEl = document.createElement('div');
newEl.className = 'my-div';
document.body.appendChild(newEl);
});
</script>
</head>
<body>
<button onclick="addDiv();">Add another DIV</button>
<div class="my-div"></div>
</body>
</html>
To make it easy to use SentinelJS asynchronously, the library dispatches a sentinel-load event that will notify you when the library is ready to be used:
<!doctype html>
<html>
<head>
<script src="//cdn.rawgit.com/muicss/sentineljs/0.0.1/dist/sentinel.min.js" async></script>
<script>
// use the `sentinel-load` event to detect load time
document.addEventListener('sentinel-load', function() {
// now the `sentinel` global object is available
sentinel.on('.my-div', function(el) {
el.innerHTML = 'The sentinel is always watching.';
});
});
</script>
</head>
<body>
<div class="my-div"></div>
</body>
</html>
