Question

I need something like enumerate in python, but in JQuery.

I have this small snippet:

array_of_urls = [....];

items = $('p[id^="gallery_thumb"]'); // get all <p> which id begins with gallery_thumb

for(var i=0; i<items.length; i++) {
    // something something with items, i and array_of_urls 
    // like:

    items[i].load( array_of_urls[i] );
}

is there a way to avoid the for loop and do it inline? like a mix between jquery .each and enumerate in python..

or some cleaner way to face a problem like this..

Answer 1

The each method gives you an index that you can use to access the array:

array_of_urls = [....];

$('p[id^="gallery_thumb"]').each(function(i, e){
  $(e).load(array_of_urls[i]);
});
