Question

I have an array of months like this:

var months = ["jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec"];

What i am trying to do is make the name of the month a variable and set an object to it like so:

for(i=0;i<11;i++){
months[i] = $(".bitem:eq("+i+")");
}

But that just replaces months[i] (if i=0 for example it would replace “jan” with the object). What i want to do is use the string that months[i] is equal to for the variable name. I tried using .toString() like this:

for(i=0;i<11;i++){
months[i].toString() = $(".bitem:eq("+i+")");
}

but I get the error:

Error: ReferenceError: invalid assignment left-hand side

Why exactly do you need to have variables names jan, feb, etc? From what I can tell, you can do everything you want by using a plain old object with properties:

var monthNames = ["jan", "feb", "mar", "apr", "may", "jun", "jul", "aug", "sep", "oct", "nov", "dec"];

var months = {};
for(var i = 0; i < monthNames.length; i++) {
    months[monthNames[i]] = $(".bitem:eq("+i+")");
}

// Example usage
var januaryItem = months["jan"];
// or equivalent: months.jan;
