For else loop in Javascript?

rated 0 times [ 145] [ 5] / answers: 1 / hits: 35406 / 11 Years ago, mon, february 3, 2014, 12:00:00

Is there a Javascript equivalent of the python 'for-else' loop, so something like this:

searched = input(Input: );

for i in range(5):

    if i==searched:

        print(Search key found: ,i)

        break

else:

    print(Search key not found)

Or do I just have to resort to a flag variable, so something like this:

var search = function(num){

    found = false;

    for(var i in [0,1,2,3,4]){

        if(i===num){

            console.log(Match found: + i);

            found = true;

        }

    }

    if(!found){

        console.log(No match found!);

    }

};

Working example (you need to use the flag):

var search = function(num){

    var found = false;

    for(var i=0; i<5; i++){

        if(i===num){

            console.log(Match found: + i);

            found = true;

            break;

        }

    }

    if(!found){

        console.log(No match found!);

    }

};
