jquery - Omit empty strings from serializeArray in javascript

Question

When using serializeArray() for a form with empty fields it returns "" for all those fields. What is the best way to omit those empty fields from the Array besides iterating over the Array and deleting them one by one?

Answer 1

Iteration is neccessary as serializeArray creates an array of objects, and each value has to be checked.
Using a filter seems appropriate :

$('form').serializeArray().filter(function(k) {
    return $.trim(k.value) != "";
});
