Why is my JSONP response blank/error from SOLR at localhost?

I've set up Solr locally. It works fine using queries in browser. I'm tryng to acces JSON-queryresults in JQuery, but I'm not able.

When I run the following request in my browser i get the following resut: http://localhost:8983/solr/Products/select?q=HPI-850&fl=id%2CPris&&rows=2&wt=json&json.wrf=solrCallback

solrCallback({
  "responseHeader":{
    "status":0,
    "QTime":1,
    "params":{
      "q":"HPI-850",
      "json.wrf":"solrCallback",
      "fl":"id,Pris",
      "rows":"2",
      "wt":"json"}},
  "response":{"numFound":3701,"start":0,"numFoundExact":true,"docs":[
      {
        "Pris":1195,
        "id":"10440"},
      {
        "Pris":1195,
        "id":"16656"}]
  }})

Running the following code in my browser at localhost I get the JSONP response from the example I found at https://www.sitepoint.com/jsonp-examples/, but I get no response from my own URL. Why? I my code bad, or does Solr block the request in any way?

        function jsonCallback(json) {
            //alert(JSON.stringify(json));
            $("#Test_JSON").html(JSON.stringify(json));
        }

        $.ajax({
            url: "http://run.plnkr.co/plunks/v8xyYN64V4nqCshgjKms/data-2.json",
            dataType: "jsonp"
        });


        function solrCallback(json) {
            //alert(JSON.stringify(json));
            $("#SOLR_JSON").html(JSON.stringify(json));
        }

        $.ajax({
            url: "http://localhost:8983/solr/Products/select?q=HPI-850&wt=json&json.wrf=solrCallback",
            dataType: "jsonp"
        });

    </script>

Solution

I don't know the details of why it did not work with JSONP, because as I understand, it should have worked. While searching for a solution I ended up enabling CORS in Solr.

I followed this guide: http://laurenthinoul.com/how-to-enable-cors-in-solr/

After doing so, I have no problem getting my Json from Solr by JQuery.
