Get part of a string using jQuery

Question

HTML code:

How can I get number \"45\" of string using jQuery?

Answer 1

Using jQuery, simply:

$("[id='block-id-45']").attr("id").split("-")[2]

For all block-id-##, you can use mask pattern from Peter's answer:

$("[id^='block-id-']").click(function(){

    row_id = $(this).attr("id").split("-")[2];
    .............
    .............
})
