json_encode (php) and json_parse (js) [closed]

I read the database with php and pack the contents into a Json:

$lbtb_json = json_encode($lbtbs);

In Javascript I get the values. When I with

this.lbtbdata = lbtb_json;    
window.console.log(this.lbtbdata);

Outputting the data, I get the following:
before parse

If I do the following in Javascript:

this.lbtbdata = lbtb_json;    
this.events = JSON.parse(this.lbtbdata);
window.console.log(this.events);

I get the following:

after parse

I would like to be able to output the following:
this.events[‘id’] or
this.events[‘date’] and so on.

Why don’t I get any more values after parsing? How do I get the values to be output individually, as described above?
