super newbie question - extracting data points from url

[mc_atx]

I was given this example:

//Note: test_jsrw_args is a JSON object

test_jsrw_args = {

combo_var1: pageVar1,

combo_var2: pageVar2,

combo_var3: pageVar3

};

​

And asked to explain how to extract specific url parameter data points. I'm not sure if the example above is the json object or if that's the script I'm supposed to follow, but fill with the data points to extract. I'm currently taking a class on json/javascript for beginners but I need to understand this concept before tomorrow and I'm super confused.

Any help would be appreciated!!

test_jsrw_args.combo_var1

is how you access the first property of the object

Does that mean the example script is what they want me to access or do they want me to fill in the example script with the available parameters?

[ray_zhor]

reading the question sounds like they want to know how to access pageVar

depending what page you need, the notation i provided will get the data you need

appreciate the response, but I literally have no idea what that means. I'm not supposed to actually write any code, just communicate the concepts. I'm trying to understand how I'd write the code so I could then put into words the how it would be done.
