javascript access a json object

Question

this might sound dumb but I am trying to display the value of content: I do console.log(teams); I open firebug on mozilla and here is what I get :

 [Object { id= "50",  content= "Team 1 test" ,  date="Tue Mar 26 2013 12:00:00"}]

when I do alert(teams.content); or alert(teams[content]); it returns object undefined.What am I doing wrong please ?

The object is wrapped in an array (notice the [ and ])

teams[0].content;

console.log(teams[0]); this returns : Object { id= "50" , content= "Team Pro-Motion test" , date= "Tue Mar 26 2013 12:00:00" }

but if I add the .content, it says undefined again

@fogsy add .content to what?

cppit Over a year ago

to teams[0] ... so when I do console.log(teams[0].content); its undefined.

@fogsy can you show us an example on jsfiddle.net or your actual site?

Its not just object, but an array of objects, . Your object is at 0th index of array.

So try this,

alert(teams[0].content)

Also, alert(teams[content]); is a wrong way. The index should be a string here.

So, another way would be,

alert(teams[0]['content']);

TypeError: eventsOfDay[0] is undefined [Break On This Error] console.log(eventsOfDay[0]['content']);

smk Over a year ago

you said teams. not eventsOfDay!

cppit Over a year ago

yes but its the same. just the variable name that is different.

@fogsy, I guess you can remove your comments now as you have find out that error is caused by something else.

Teams is an array.

To read a value you need to index it

teams[index].content

on here it asys index is not defined.

I didnt mean to say use index per se.. but a variable that indexes into the array.. for example if var size = teams.length; now you can use teams[x].content to access the xth element of the array. where 0<= x < size
