Dunno if this is the forum for it but I've had a need for a slight
modification to Try.these() from prototype.js. In my situation I
wanted to make sure that as many functions ran as possible instead of
just the first successful.
It's useful in situations where you have a lot of if(object) { /* do
stuff with object */ } statements in a row.
The return value wasn't important to me at the time. so I just chucked
it into an array. Perhaps someone could suggest something better to
return?
So here it is:
Try.allThese = function(){
var returnValue = [];
for (var i = 0; i < arguments.length; i++) {
var lambda = arguments[i];
try {
returnValue.push(lambda());
} catch (e) {
returnValue.push(false);
}
}
return returnValue;
};
