Access a variable value from dynamically using javascript

Question

I am using javascript. I have a global variable like:

var contentlabel = {
'post':'Posted Blogpost',
'like':'Liked your Blogpost'
};

I want to access the value of contentlable.post dynamically in another function dynamically based on the value retrieved (like, post, ..) as below:

var CONTENT_TYPE=content[i].contentType;
alert(CONTENT_TYPE);   //line 1  --> proper output
alert(contentlabel.CONTENT_TYPE);  //line 2  --> undefined
alert(contentlable.post);  //line 3  --> proper output

Where content is an array consisting of 'post' and 'like'. At line 1 I am getting proper output say: post or like In place of 'post' I want to display 'Posted a Blog', so I tried like contentlabel.CONTENT_TYPE, but its not replacing CONTENT_TYPE with either post or like.

Can anyone suggest a way to bind this dynamically.

You should use square bracket notation: contentlabel[CONTENT_TYPE].
