looping a specific object property

[jimfog]

I have 2 objects:

{id:3, title:kostas Papageorgiou, staff_ID:5, start:2014-04-09 04:30:00, end:2014-04-09 06:00:00,…}1: {id:4, title:gianis, staff_ID:5, start:2014-04-10 04:00:00, end:2014-04-10 06:00:00, color:#0072C6,…}

I want to loop only through the property title of them.How am I going to do it?

 

I have found code in the web that loops through all of the properties but not for a specific one.

In other words and having as an example the above I want to get Kostas Papageorgiou and gianis.

Just loop through the array of objects and access the title property of each one. I'm not sure where you're stuck with that. What code do you have?

[jimfog]

This is the code I am using which and which loops through all of the properties:

    for (var key in event) {                      if (event.hasOwnProperty(key)) {                        console.dir(key + " -> " + event[key]);                      }                    }

As you see I am printing the results in the console.event is the name of the object

 

As I said above I want to access only the title property.

I do not understand the problem. Are you unaware that you can access object properties directly? If so, how did you get this far without knowing that? You can use event.title, or event["title"]. Why are you looping through the properties?

Elements have title properties (ie tooltips) but do events have them?

[justsomeguy]

That's not an event object, it's just a variable name.

if(obj.property){  console.log('obj has property defined');}

[Ingolme]

if(obj.property){  console.log('obj has property defined');}

That's not going to work with properties that have values such as "", 0 or false

I think it's odd that I can't use...

var t = events[1].1.title; // 'yyy'

for...

var events = [{0:{id:1,title:'xxx',start:100}},{1:{id:2,title:'yyy',start:150}}];

Ah yes, correct. the property will be there, but will not pass that test. I guess I oversimplified the example of object notation.

[justsomeguy]

var t = events[1].1.title;

Property names cannot be numeric.

[davej]

Yeah, non-numeric works.

Because there is more than one object at any moment. That is why I am using loop.

Anyway I found a workaround and no loop is needed at all...but I am just letting you know why I used loop in the first place.
