I would like to convert and array in this format
var values = [1,2,3];
To an array in this format
var data = [
{x: 0, value: 1},
{x: 1, value: 2},
{x: 2, value: 3}
];
-
typo var data = [ {x: 0, value: 1}, {x: 1, value: 2}, {x: 2, value: 3} ];Leo Ku– Leo Ku2015-08-31 02:35:04 +00:00Commented Aug 31, 2015 at 2:35

You could simply use the Array.prototype.map method:
var data = values.map(function(el, i) {
return {
x: i,
value: el
}
});

A basic option would be:
var values = [1,2,3];
var newValues = [];
for(var i = 0;i < values.length;i++){
newValues.push( {x: i, values: values[i]} );
}

Maybe something like this will do the trick:
var values = [1,2,3];
var _dict = [];
for (var i = 0; i < values.length; i++) {
_dict.push( {x: i, value: values[i]} );
}

@Oka Thanks. Didn't knew that. Is the modified code good enough?

I didn't downvote, but your answer has several problems. 1. OP wants to create an array of objects not an object. 2. You shouldn't use the
for ... in loop for iterating through arrays. 3. The x and y should be separate properties. Define the _dict as an array, iterate properly and then use the Array.prototype.push method for pushing an object into the array.sam
@Vohuman Thanks for commenting. You didn't downvote but I did upvote your answer. I am new to javascript as well that's why the answer is mediocre :)

Thanks for that :). Yes, but you forgot to define the
_dict variable as an array. var _dict = []; |
