findup-attribute
Given a child attribute, findup-attribute will traverse its way up the DOM
until it finds and returns an element with the expected attribute.
Usage
findup(child, nodeAttr)
Find the closest parent attribute with attribute nodeAttr.
For example, the following will pick up clicks on elements using a
on-click attribute with only a single event listener:
var findupAttribute = require('findup-attribute')
document.body.addEventListener('click', function(e) {
var li = findupAttribute(e.srcElement, 'on-click')
}, false)<body>
<ul>
<li on-click="thing"><a href="#">click me</a></li>
<li on-click="thing"><a href="#">click me</a></li>
<li on-click="thing"><a href="#">click me</a></li>
<li on-click="thing"><a href="#">click me</a></li>
</ul>
