Problem in accessing a variable's changed value outside of if block in javascript code

$("#submit").click(function(){
        var query=getquerystring() ; //get the query string entered by user
        // get the JSON response from solr server 
        var newquery=query;

    $.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+query+"&json.wrf=?", function(result){
            //$.each(result.response.docs, function(result){

                if(result.response.numFound==0)
                {

                $.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+query+"&spellcheck=true&json.wrf=?", function(result){


                    $.each(result.spellcheck.suggestions, function(i,item){
                        newquery=item.suggestion;

                    });

                });

                }

In the above javascript code a variable newquery initialy having value of query. but when the if condition is true its value have changed. but my problem is i am not getting its changed value outside of if block while i want this changed value. how can i do this.

Please reply.

EDIT

Can i make it as:

   $.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+query+"&json.wrf=?"
  {
  async:false
  }, 
function(result) {

The problem is that $.getJson is asynchron.
