attr-range

find ranges for wiring up live automatically updating collections

example

var arange = require('attr-range');
var rangef = arange(function (range) {
    console.log(range);
});
 
var elems = document.querySelectorAll('*[data-start]');
for (var i = 0; i < elems.length; i++) {
    rangef(elems[i]);
}

methods

var arange = require('attr-range');

var rangef = arange(start='data-start', end='data-end', function (range) {})

Register a callback to fire when range elements have been gathered.

range objects have:

• range.start - start key in the collection range
• range.end - end key in the collection range
• range.range - object with only start and end keys; useful for handing to db.createReadStream()
• range.element - container element for all the items in the range

rangef(elem)

Call the rangef() function on each element elem that has the start and end keys to populate the callback with.

install

With npm do:

npm install attr-range
