JSON AJAX url想要更多

Question

I am using D3 to create some county data with their choropleth example. I am using the d3.json option vs. the jquery .ajax. I have a URL that when I use it just does not load. After some research I found that the web service requires an additional parameter:

   {'county': {'year': 2002,'stat': 'crime'}} 

So the connection to this url keeps failing on me.

I tried to add the additional required parameters for the web service as follows:

d3.json("http://url/states", function (json) {
    data = "{'county': {'year': 2002,'stat': 'crime'}}"
    //basic d3 stuff from here below
    counties.selectAll("path")
        .attr("class", quantize);
    dataType = json,
        contentType = "application/json; charset=utf-8";
});

I just cannot connect without those params in the call and I am not sure how to incorporate them.

It might be that single quotes aren't being counted as valid syntax. You can validate your syntax at JSONLint.com

Try double quotes instead

data = '{"county": {"year": 2002, "stat": "crime"}}'
