Question

I’m looking to use arrays to create unique names for variables. I am not looking to store any calculated values in the arrays, but rather be able to declare variables using arrays to store the values. My attempts and research how to accomplish this leads me to think that it’s not even possible. I’d appreciate it if someone could let me know and if it is possible an answer/example on how to do it. I’ll post a simplified example on what I’m hoping to get working.

var indices = ["index01", "index02", "index03"];
var keys = ["key01", "key02", "key03"];
for (var index = 0; index < indices.length; index++)
{ 
    for (var key = 0; key < keys.length; key++)
    { 
        var  indices[index]+keys[key] //Looking for var index01key01, var index01key02 etc...
    }
}

Well, basic javascript variables are in the window scope, so try:

var indices = ["index01", "index02", "index03"];
var keys = ["key01", "key02", "key03"];
for (var index = 0; index < indices.length; index++)
{ 
    for (var key = 0; key < keys.length; key++)
    { 
        // you can now use the variable as window.index01key01, or just index01key01
        window[indices[index]+keys[key]] = null;
    }
}
