Question

I always come across situations in programming where I want to have a bunch of variables defined in a loop (e.g., soldierA, soldierB, soldierC,…) and assign them to certain objects.

someClassA = Ext.extend(someClassB) {
    initComponent {
        this.weekdays = [ 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 
                          'Friday', 'Saturday','Sunday' 
                        ];
        for(var i = 0; i<7; i++) {
            var dummy = "this.vacation" +this.weekdays[i]; 
            dummy = 1;
        };
        console.log("I desire the following to be a 1: " +this.vacationMonday);
    }
} 

Console lists an undefined elements.

What is the recommended course of action?

Answer 1

You have to use the bracket notation to set dynamic variable names. Also note you have to assign directly, not the way you have it listed.

this["vacation" + this.weekdays[i]] = 1;
