Hi! I have got this code:
var data;
data = {items: [
{value: “Value1”},
{value: “Value2”},
{value: “Value3”},
]};

I would want to declare data and to add Values dinamically, because sometimes i have got 2 values, other times 3,…
How could i do this?

Thank you very much!!!

Now add items when you need to using the push() method like so:

[CODE]data.items.push('item 1');
data.items.push('item 2');
data.items.push('item 3');[/CODE]

@mahoniauthorNov 14.2010 — Thanks for your reply.

It doesnt work for me.

In my example:

data = {items: [

{value: "Value1"},

{value: "Value2"},

{value: "Value3"},

]};

[B]if i put this alert:

alert(data.items[0].value);

The result is: Value1[/B]

But in your example if i put the same alert, the result is undefined:

var data = {items: new Array()};

data.items.push("Value1");

data.items.push("Value2");

data.items.push("Value3");

[B]alert(data.items[0].value);[/B]

Result: undefined

Why?

Thanks!!!!!

@MikeOSNov 14.2010 — Remove the value property from my example code, just have:

alert(data.items[0]);

@mahoniauthorNov 14.2010 — My problem is the next one:

I need to be exactly like this:

data = {items: [

{value: "Value1"},

{value: "Value2"},

{value: "Value3"},

]};

But dynamically generated. Why?

Because i am using jquery autosuggest plugin(https://github.com/fredwu/jquery-autosuggest) and if you pass this code, it recognize Value1, Value2,Value3.

But if i pass your code it does not recognize any values.

I think that "value" is important, but no idea why.

Thanks, thanks, thanks!!!

@MikeOSNov 14.2010 — Pass on object in the correct format to the push() method instead:

[CODE]
data = {items: new Array()};

data.items.push({value: 'item1'});
alert(data.items[0].value);
[/CODE]
