我得到我必须使ajax调用异步的问题。所以我确实喜欢上面的代码，但仍然无法在if块之外获取更新的newquery。它仍然显示newquery的旧值。请建议我在哪里做错了

编辑

$(document).ready(function(){

// This function get the search results from Solr server

$("#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)

{

$.ajax({

url: "http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=100&q="+query+"&spellcheck=true&json.wrf=?",

async:false,

dataType: 'json',

success: function(json){

$.each(json.spellcheck.suggestions, function(i,item){

newquery=item.suggestion;

});

}

});

}

$.getJSON("http://192.168.1.9:8983/solr/db/select/?wt=json&&start=0&rows=20&q="+newquery+"&sort=price asc&hl=true&hl.fl=description&hl.usePhraseHighlighter=true&json.wrf=?", function(result){

现在，如果result.response.numFound == 0，我想在$getjosn()中使用此更新的newquery，否则newquery将保留旧值
