how to define a path when grabbing var from JSON?

[ohdang888]

var obj = {2:{"name":"Test for number 2", "other":"yup"},
4:{"name":"What i want!", "other":"yup"}
};

var test = 4;
alert(obj.test.name);// Would say "What i want"
var test = 2;
alert(obj.test.name);// Would say "test for number 2"

 

the variable "test" differs, so the path the values i'm looking for is differnt, how is this achieved?

 

Thanks!

You've created an array, so you simply reference it as an array element.

var obj = {2:{"name":"Test for number 2", "other":"yup"},
4:{"name":"What i want!", "other":"yup"}
};
var test = 4;
alert(obj[test].name);// Would say "What i want"
var test = 2;
alert(obj[test].name);// Would say "test for number 2"

this code should work..

 

var obj = {2:{"name":"Test for number 2", "other":"yup"},
4:{"name":"What i want!", "other":"yup"}
};

for (key in obj)
{
    alert(obj[key].name);// Would say "What i want"
}
