javascript - Remove string from array -

i have array contain number , string, want remove string array. here array:

var numbonly = [1, 3, "a", 7];

in case, want remove a numbonly (result numbonly = [1, 3, 7]).

thanks.

you can utilize this:

var numbonly = [1, 3, "a", 7]; var newarr = numbonly.filter(isfinite) // [1, 3, 7]

the above works if don't have strings "1" in array. overcome that, can filter array this:

newarr = numbonly.filter(function(x){ homecoming typeof x == "number"; });
