Why not just set them all to have the class `BasketProduct` as well as a specific `id`? — SuperBiasedMan, Sep 15 '15 at 11:26

Edited:

var ul = document.getElementsByClassName('productdetails')[0],
i, temp;

for (i = 0; i < ul.children.length; i += 1) {
    temp = ul.children[i].id;
    if (temp.indexOf('BasketProduct-') > -1) {
        // do smth
    }
}

Why `i+=1`? Why not `i++` also this doesn't have a condition to check for `BasketProduct-??` so this isn't really worthy of an answer since the OP wants to know how to find those elements, not print out all List Item elements. I guess adding something like `if(li[i].id.indexOf('BasketProduct-') > -1){console.log('Found: '+li[i].id);}` would make this answer better for what the OP is asking for but using `document.querySelectorAll('li[id^=BasketProduct]');` is much easier rather than having to dig them out of a for loop. – NewToJS Sep 15 '15 at 10:36
well i pasted just a part of code, not solution and ++ operator was used for pointer increment in other languages, but it can be used in JS for +1 increment ... – J. Kovacevic Sep 15 '15 at 10:58
So if your post isn't a solution it belongs in the comments, not as an answer. – NewToJS Sep 15 '15 at 11:06
you must have 50 reputation to comment* – J. Kovacevic Sep 15 '15 at 11:55
Exactly, it's for a reason. You have more chance of being down voted for posting like this.. Meaning it will take you much longer to reach reputation 50. – NewToJS Sep 15 '15 at 23:18
