Execute JavaScript function from object
Is it possible to execute function this way:
this.values(value);
not
this.values[value]();
this.values[value].call();
If so, how? Or any other methods? Thank you.
Here is my code:
write: function(value) {
this.values = {
"red": function() { /* do something */ },
"orange": function() { /* do something */ },
"blue": function() { /* do something */ }

return this.values[value]();
}
write("red");
May be you could use a var inside:
write: function(value) {
var values = {
red: function() { /* do something */ },
orange: function() { /* do something */ },
blue: function() { /* do something */ }
};
return values[value];
}
And return the function instead of running it inside. And call it after.
No. But there isn't anything wrong with how its done at the moment.
You could always do this:
write: function(value) {
switch(value){
case "red":
/* do something */
break;
case "orange":
/* do something */
break;
case "blue":
/* do something */
break;
default:
/* do something */
break;
}
}
write("red");
