给定以下从 Solr 实例中获取 JSON 数据的函数:
var url = "http://myserver:8080/solr/select?indent=on&version=2.2&q=(title:*Hollis* OR sub_title:*Hollis*+OR+creator:*Hollis*+OR+publisher:*Hollis*+OR+format:*Hollis*++OR+lcsh:*Hollis*++OR+loc_call_num_subject:*Hollis*+OR+note:*Hollis*++OR+toc:*Hollis*)AND+Match_Confidence:[.75+TO+*]&start=0&rows=3500&fl=Geocoded_Field,title,id_inst,Match_Confidence,Conjunct_Longitude1,Conjunct_Latitude1,Anchor,note,creator,format,language,pub_location,publisher,score&wt=json&group=true&group.field=title";
$.getJSON(url, function(data){
console.log("EXAMPLE TYPE:"+data.grouped.title.groups.docs[0].title);
});
例如,我如何循环浏览每个响应“文档”(下面发布的数据)并抓住每个“标题”出现?我已经尝试了 data.grouped.title.groups.docs[0].title 的许多变体,但没有成功。我在想我只是在数据访问字符串(data.grouped.title.groups.docs.title)中的顺序不正确。
