jquery - Knockout JS - Value of span -

my application mvc5; trying value of knockout span using following:

<span id="total" data-bind="text: allimages().length"> </span>

i see 10 on screen correct value.

tried use:

var total = $('.total').text(); alert(total);

don't value, tried .val().

edit can value if use function:

   function getvalue() {         var total = $('#total').text();         $('#mytext').val(total);         alert(total);     }

is there way value onchange of span text?

you need $('#total'), not $('.total')

#total finds element id, correct html span id; .total means classname, , there no div in code class, it's correctly matching no elements.
