how do i insert element in knockout array at specific index
knockout.js, ko.observablearray
Solution
Use `splice`. The docs aren't real clear on this (I had to double check it myself), but you can use this just like the regular javascript .splice to insert elements as well as remove them. For example:
var vm = {
array : ko.observableArray(["foo","bar"])
};
ko.applyBindings(vm);
function Add() {
vm.array.splice(1,0,"ra"); // at index 1 - remove 0 elements and add "ra"
}
Add(); // "ra" gets inserted between "foo" and "bar"
