D3JS or Jquery: convert JSON string to integer

Question

I am creating a scatter chart using D3. The input JSON for the chart stores data within quotes, making them strings, while i need it in integer or numeric format.

This is what i am getting,

var data = [{"collision_with_injury": "2500", "dist_between_fail": "12000"}]

This is what i need,

var data = [{collision_with_injury: 2500, dist_between_fail: 12000}]

Is there a function in D3 or Jquery to convert the data object to one without quotes?

Adam's comment helped me indirectly. I was not able to add the function as described but prefixing '+' to collision_with_injury and dist_between_fail where i am calling them, resolve it. thanks! '+' converts a string to integer — Rohan Sandeep

Why were you not able to add the function as described in Adam's comment? — Yogesh

Great! My answer was missing a closing parentheses; I've just edited it in. — Adam Pearce

That was it, my bad...i use notepad++ it doesn't give me hints of missing parenthesis. Thanks Adam and Yogesh! — Rohan Sandeep

4

data.forEach(function(d){
  d.collision_with_injury = +d.collision_with_injury;
  d.dist_between_fail = +d.dist_between_fail;
});

If there are more properties in the object that need to be cast as a number, you can iterate over them w/ d3.keys().

Look at this fiddle.

var data = [{"collision with injury": "2500", "dist_between_fail": "12AS00"}];
var dataLength = data.length;
if(dataLength>0)
{
    var keys = d3.keys(data[0]);
    var keyLength = keys.length;
    for(var i = 0; i < dataLength; i++)
    {
        var datum = data[i];
        for(var j = 0; j < keys.length; j++)
        {
            var key = keys[j];
            if(!isNaN(datum[key])) datum[key]=+datum[key];
        }
    }
}
