Looks like you are getting an array of Objects. You need to pick the first element of data and call the property on it.

this.obj=data[0];
this.y=this.obj;
console.log(this.y.name);

Can you share the exact log for both cases? – Shubham Singhal Jun 21 '18 at 12:00
for both cases the output is "undefined" – i.s.n raju Jun 21 '18 at 12:07
Add console.log(data) and share that. Might be your data is not proper. – Shubham Singhal Jun 21 '18 at 12:08
for console.log(data) , the data coming properly. but entire object is coming. But my requirement is only one field in that object – i.s.n raju Jun 21 '18 at 12:12
Paste that data here for debugging. – Shubham Singhal Jun 21 '18 at 12:13
[{"_id":"5b272f50797dcc0bf8bad590","name":"aa","mobile":"bb","idproofno":"cc","car_bike":"dd","flat":"108","block":"B","customer":"suri","dov":"2018-06-18"} – i.s.n raju Jun 21 '18 at 12:15
One more thing, what happens when you log data[0] – Shubham Singhal Jun 21 '18 at 12:17
the output is like this ' [ ' for console.log(data[0]) – i.s.n raju Jun 21 '18 at 12:23

Here is an simple example you can modify your convenient,

public data = [{ "_id": "5b272f50797dcc0bf8bad590", "name": "aa", "mobile": "bb", "idproofno": "cc", "car_bike": "dd", "flat": "108", "block": "B", "customer": "suri", "dov": "2018-06-18" }];

  constructor(){
    for(let item of this.data){
      console.log("Data->>",item.name); 
      //here you can get any like mobile, car_bike, flat, block, customer,
    }    
  }
