Question

There is a json data:

var json = {  
    "entry" : [{ 
        "category" : {
            "@scheme" : "http:\/\/www.douban.com\/2007#kind", 
            "@term" : "http:\/\/www.douban.com\/2007#movie"
        }, 
        "title" : {
            "$t" : "Real Steel"
        },
        "db:attribute" : [{
            "$t" : "USA", 
            "@name" : "country"
        }]
    }]
}

alert(json.entry[0].title.$t) can print “Real Steel”. However,
how to get the http:\/\/www.douban.com\/2007#kind and USA in Javascript　？　

　It contains @ and :, I don’t know how to cope with it.

Answer 1

Use square brackets and a string instead of .

json.entry[0].category["@scheme"]
json.entry[0].category["@term"]
json.entry[0]["db:attribute"][0].$t
json.entry[0]["db:attribute"][0]["@name"]
