在这个JSON中，我想要在ICON对象中获取“URL”，并从“RelatedTopics”中的每个对象中获取“TEXT”..但是我无法找到如何。请帮助摆脱这个问题。在此先感谢

Answer 1

你要循环对象的数组和使用索引来检查每个属性：

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; });
