8,744 PointsI want to then sort list item in a some order. How does one do that. Is there a function that can help me?
I want to input a number , and sort a list item based on the input. For instances, if I input a one, the list item will go to the top of the list. Append child only just puts it at the end of the list. Is there anything that lets me sort a list numerically based a numeric input?

sort(append());
I'm not sure of the precise syntax for that though but I hope it points you in the right direction.

var myList = [11, 10, 12, 14, 15];
myList.sort(compare)
function compare(a, b) {
return a - b;
}
This will give your array a numeric sort.

8,744 PointsI tried that, and it just tells me that sort is not defined. I think sort only works with arrays not list items. Or am i wrong? I cant seem the find a method that works with list items.
