create []array dynamically in Javascript

Question

Probably this will be a real stupid question to ask but im new in javascript and stuck with dynamic creation of array like in below format:

items = [{
 "Date": "2012-01-21T23:45:10.280Z",
 "Value": 7
}, {
 "Date": "2012-01-26T23:45:10.280Z",
 "Value": 10
}, {
 "Date": "2012-05-30T23:45:10.280Z",
 "Value": 16
}];

Please guide me how do i create above array dynamically using javascript syntax.

Thanks in advance!

• Vivek Jain: Please share what have you tried so far.
• Bergi: Dynamically from what? Current answers are as static as your array literal.
• Milan Mendpara: var items = []; for(i in d.date) { var arr = i.split("-"); var Item = new function(){ this.Date = arr[0]; this.Value = arr[1]; } items.push(Item);}

Answer 1

var items = []; // initialize array
items.push({ // add 1st item
 "Date": "2012-01-21T23:45:10.280Z",
 "Value": 7
});
items.push({ // add 2nd item
 "Date": "2012-01-26T23:45:10.280Z",
 "Value": 10
});
items.push({ // add 3rd item
 "Date": "2012-05-30T23:45:10.280Z",
 "Value": 16
});

And to view it:

console.log(JSON.stringify(items));

See:

• Javascript Array
• Array.prototype.push to add elememts

• Cerbrus: Why do you use JSON.stringify for the log?
• Brad Christie: @Cerbrus: Just a quick and dirty way to visualize the data's there. You could console.log(items) but then you're having to use the debugger to expand out the object and each element in the array to confirm it's been populated.

Do you mean like this:

items = [];
items.push({
 "Date": "2012-01-21T23:45:10.280Z",
 "Value": 7
});
items.push({
 "Date": "2012-01-26T23:45:10.280Z",
 "Value": 10
});
items.push({
 "Date": "2012-05-30T23:45:10.280Z",
 "Value": 16
});
