You can use a loop, and convert each element of the array containing string, into a integer. parseInt() is a method which converts string into a integer, it takes two arguments, first: the string, second: the base number of the integer

var a=["1","2","3"]; 
console.log(a); 
b=[]; 
for(i=0;i<3;i++){
    b[i]=parseInt(a[i],10)
}; 
console.log(b)
