}

In this JSON i want to get "URL" inside the ICON object and "TEXT" from each object inside "RelatedTopics".. But i was unable to find how. Please help to Get out of this problem. Thanks in advance

Answer 1

You have to loop the array of objects and use the index to check the properties of each:

for (var i = 0; i < data.RelatedTopics.length; i++) {
    console.log(data.RelatedTopics[i].Text); //text;
    console.log(data.RelatedTopics[i].Icon.URL) //url;
}

Answer 2

您也可以尝试

results.map(function(e){ return e.Icon.URL; });
