Remove multiple html5 data-attributes with jquery

Question

So jquery api says the following:

Removing data from jQuery\'s internal .data() cache does not effect any HTML5 data- attributes in a document; use .

Answer 1

Vanilla JS below clears all data attributes. If you want to add some if logic to remove a subset of data attributes, it should be trivial to add that functionality to the below JavaScript.

function clearDataAttributes(el){
    if (el.hasAttributes()) {
        var attrs = el.attributes;
        var thisAttributeString = "";
        for(var i = attrs.length - 1; i >= 0; i--) {
            thisAttributeString = attrs[i].name + "-" + attrs[i].value;
            el.removeAttribute(thisAttributeString);
        }
    }
}
