Is it possible to get a numeric position of an element using the find function?  I have a div that contains multiple checkboxes.  I want to get a number for each checkbox either its position in an array or list.  Or as it finds it I want to assign it a value.  I guess I could do this without the find function but I wanted to know what the find function was able to do as it finds each checkbox.

It is not clear what you ask.

If you find input type checkbox, you will get an enumerable object back with each checkbox in the order it was found.

You can use the .eq selection to get at specific index

I am doing a $("divid").find(":text").prop("value", ?)

I want to put the ordinal value in the ? or the numeric order of the element in the dom.

It needs to be dynamic.  This is probably not possible using the find function.

I do not understand what you just said. Show some HTML or creat a jsfiddle.net

So it would be as follows.

$("div_id").find("input:text").each(function ()  {
    x += 1;
    $(this).prop("value", x);
}

But there still is a problem.  The text boxes are in a two column table.  So the dom order is vertical since the textboxes are in two td tags per row.  I want to number going vertical down each column.
