JavaScript Accessing a value from an object

Question

When i do console.log(data) on a particular script that i'm using, i get the following

[Object {
    name = "videobody", value = "asdasd"
},
Object {
    name = "IMUFiles[]", value = "selected_arrow1327549445.png"
},
Object {
    name = "filename", value = "testing"
},
Object {
    name = "allow_comments", value = "y"
}]

How can i access selected_arrow1327549445.png from data

kinda sad when an answer isn't long enough to pass validation... — jondavidjohn

Accessing it directly would be data[1].value or are you wanting to dynamically find it based on something else? — PriorityMark

order of the objects can change. I'm just looking to grab the filename which in this example is located in the second object — Pinkie

How does this structure get assigned to variable. It's invalid Js according to JsLint. Doesn't run : jsfiddle.net/kFQE6 — gideon

It's an array of Objects each with a name and value property, so:

data [1].value

EDIT: Well, since you said the order can change, maybe just loop through:

for (var i = 0; i < data.length; ++ i)
{
    if (data [i].name === "IMUFiles[]")
    {
        alert (data [i].value); 
        break;
    }
}

it's not necessarily in this particular order. Order of the objects can change.

@Pinkie Do you mean you want to search that value?

gideon Over a year ago

So you want to traverse or search the structure?

Yes, that's just the way it's logged to the console.

@gideon yes you're right, it's doesn't validate. This is how i got it from console. I too wonder what is wrong with the code and how to make it work in jsfiddle
