Question

How do you refer to elements of array in Jquery? For instance - input type of text with name="a[]" attribute.

You can select them with an attribute-equals selector on the name attribute, like this:

$("input[name='a[]']")

This will get you all elements, if you want one at a specific index as a jQuery object use .eq(), or as a DOM element use .get(), like this:

$("input[name='a[]']").eq(0)  //first element wrapped in jQuery object
$("input[name='a[]']").get(0) //first raw DOM element

Nitpicking: Since it was also specified that the input type be limited to text, the more correct selector would be $("input[name='a[]'][type=text]").
