javascript - Updating existing key value pair throws <Object> has no method 'push' error -

i'm trying update existing javascript object new key value , update existing value so

$.each(eventsdata, function() {     if (this.id== "eb_0") {         this.push({             author_name: "john seeds" //new key value pair added.             title: newtitle_var //to updated         });     } }); console.log(this.eventsdata)   

my object looks this.

[     object { id="eb_0", title="dayy", date=date, more...},      object { id="eb_1", title="dayz", date=date, more...},     object { id="eb_2", title="dayx", date=date, more...}           ] 

currently console.log outputs following error.

uncaught typeerror: object #<object> has no method 'push'  

could me figure out please?

you use:

$.each(eventsdata, function () {     if (this.id == "eb_0") {         this.author_name = "john seeds"; //new key value pair added.         this.title = newtitle_var; //to updated     } });
