Silent error when first argument is jQuery object

[jcubic]

If you pass jQuery object as first argument component is created but the return object is not tagger object. Which in turn throws different error when you try to invoke a method.

The issue is that tagger thinks that jQuery object is an array and doesn't return tagger object but an array.

        if (input.length) { 
             return Array.from(input).map(function(input) { 
                 return new tagger(input, options); 
             }); 
         }

This also occurs if you initialise using document.querySelectorAll which will return a NodeList even if only a single element exists.

Adding this to the top of the function tagger(input, options) will flatten the array if it contains only one element, works for both $() and document.querySelectorAll()

if (input.length && input.length === 1) {
    input = Array.from(input).pop();
}

@lucasnetau do you want to create a PR with this fix?

[lucasnetau]

@jcubic sure I'll make one. I'll also add some documentation around if a single instance is created it will always be returned as an object even if it was provided in a single element array.

Single Instance initialised => tagger() returns object
Multiple instances initialised => tagger() returns object[]
