How do I add parameters to an object using variables?

Question

I have this snippet of code:

var ShopLogicOptions = {};
ShopLogicOptions.params = {orderId: "'" + JS_OrderNo + "'", cartItems:[JS_arrCartItems], subTotal: "'" + JS_SubTotal + "'",...

How do I correctly put variable JS_OrderNo in the position it is at?

The other server is receiving this: "'9134832'",

And it should be this: '9134832',

EDIT: When I document.write JS_OrderNO it looks like this 9134832, so I have to add the single quotes.

You don't have to add the single quotes. It looks like that because it's a number. Heck, document.write('abc'), you don't see quotes there either. The quotes are only needed when making string literals. "'" + JS_OrderNo + "'". This literally makes the string '9134832' (the quotes are part of the string). You don't need to add quotes. — gen_Eric

I didn't understand your edit at all! why do you need to quote? — gdoron

I am sorry if I wasn't clear. The reason is because that is how shop logic wants them, all variables can be treated as strings. This is just a tracking app. — JoJo

@JoJo: All variables can be treated as strings without any processing by you. Just assume it's a string, and it should just work. — gen_Eric

@Rocket. But if a function expect to get strings ONLY, (for some unknown reason) numbers won't do. you can simply parse any variable to string using ""+ variable or String(variable) — gdoron

Remove the quotes.

var ShopLogicOptions = {};
ShopLogicOptions.params = {
    orderId: JS_OrderNo,
    cartItems: [JS_arrCartItems],
    subTotal: JS_SubTotal,
    ...
};

If you really need a string instead of a number, use this:

orderId: String(JS_OrderNo),

Maybe this is what he should have asked, but he's asking for a string.

Thanks, Are the single apostrophes automatically added then?

He didn't mention that he needs a string. My guess is that he simply doesn't want quotes in the value. @JoJo: Try it without converting to a string. Only if that doesn't work change the code to create a string. Then the value would be enclosed in quotation marks when converting it to JSON.
