Getting index of an array's element based on its properties

Question

I have a JavaScript array of objects like this:

var myArray = [{...}, {...}, {...}];

Each object has unique id among other pro

Answer 1

If each id is unique, you can do it like this:

o1 = {id:1}
o2 = {id:2}
o3 = {id:3}
o4 = {id:4}
a = [o1,o2,o3,o4]
a.indexOf( a.filter( function(i){return i.id==4} )[0] );
