jquery: how to traverse upwards incrementally (adding parent()) via function?

this code below selects all the given children from the parent.

$(this).parent().find(this.attr("tagName").toLowerCase())

however, i dont know how to traverse upwards with the parent(). i would require a function that would automatically keep adding .parent() each time the function is called.

For example, i call function once and it return开发者_如何学运维s $(this).parent().find(this.attr("tagName").toLowerCase())

I call the function for second time again and it returns $(this).parent().parent().find(this.attr("tagName").toLowerCase())

Third time, $(this).parent().parent().parent().find(this.attr("tagName").toLowerCase())

$('p:eq(0)').parents().each(function() {
    var el = $(this).find( $(this).attr('tagName').toLowerCase() );
    if ( el.length ) {
        console.log(el);
    }
});

JQuery has a function equivalent to the find which works upwards rather than downwards called closest added in jQuery 1.3

For example

$(this).parent().closest(this.attr("tagName").toLowerCase())
