javascript - How to select an item by attribute without jquery? -

i need select element this: $('[data-key=' + objectid + ']'), need select without jquery, using document.queryselector or else on pure js.

you can document.queryselectorall('[data-key=' + objectid + ']') , loop through results

var allkeys = document.queryselectorall('[data-key=' + objectid + ']');  [].foreach.call(allkeys, function(elem){    console.log(elem); //do stuff each element });
