A portion of data of the data cycle json

Demand is to take data0, data1 and so on, then maybe there will be data7,8,9, so if the data will be used for in taking all taken out, not only data0 ~ 4, so you can use data [ "key value name + variable "] form
for (var J = 0; J <data.count; J ++) {
the console.log (Data [" Data "+ J +" "]);
}
