array in javascript
i have a piece of code like below
var abc =
{
2: {label: "raju"},
10: {label: "samu"},
3: {label: "sidh"},
1: {label: "kat"},
};
for(var i in abc){ alert(i); }
in mozilla fire fox it alerts 2,10,3,1. but in chrome it shows 1,2,3,10
but my requirement is the first one (as shown in fire 开发者_StackOverflowfox) what to do for getting the same result in chrome?
The order in which the "for(var i in ...)" retrieves the items is not defined. For an array-like behaviour you have to use an array ;)
var abc = [
{ nr: 2, label: "raju" },
{ nr: 10, label: "samu" },
{ nr: 3, label: "sidh" },
{ nr: 1, label: "kat" }
];
for (var i = 0, length = abc.length; i < length; i++)
alert(abc[i].nr);
