Question

I have an Ajax request that can return more than one valid value, so i am using the “OR” operator to analyse the response, like this:

if(json.reply == "d" || json.reply == "e" || json.reply == "i" || json.reply == "j" || json.reply == "k" )

My real code has more comparisons yet, so is there a more readable and elegant sintaxe in Javascript to write this? Something like the SQL “IN” operator:

if( json.reply IN ("d", "e", "i", "j", "k") )

Thanks for any suggestions!

Switch statement is another possible way:

switch (varName)
{
case "mike": case "joe": case "larry": 
alert('cool');
break;

default: 
alert('also cool');
break;
}
