Question

I’m trying to get all the found elements within a <div>, but by default it stops when it found the first occurrence, but I want it to list every found element’s id value.

So this doesn’t work:

listy = $("DIV").find("SPAN").attr("id");

I’ve been experimenting with .get and .map, but I think they’re not what I want..

Answer 1

listy = $("div").find("span").map(function(){
    return this.id;
}).get();

Without find is even better:

listy = $("div span").map(function(){
    return this.id;
}).get();

If you want only <span> with id attribute defined, change the selector to:

$(div span[id]).map(...)

---

If you want all the ids as a string:

listy = $("div span").map(function(){
    return this.id;
}).get().join('');

The parameter of join is the delimiter, e.g. .join('-') or .join(',') or without: .join('')
