选择没有特定索引的子项（jQuery）

Question

I want to select some children without a certain index like using eq() in reverse.

I also need to be able to pass the index number as a variable .

Answer 1

$("#foo").children().not(":eq(2)");

This selects all children of foo except the 3rd one ( eq() uses Javascript's 0-based indexing).

Example .

To pass a variable to it:

var num = "2";
$("#foo").children().not(":eq(" + num + ")").css("background-color", "red");
