Need to take variables from user input (Javascript ) -
if user gives input this: xxx yy zz. need , detect xxx variable , take yy xxx1(variable1) & zz xxx2(variable2).the values of xxx1 , xxx2 used in someother files.
this code using:
var str = prompt("enter values") ; var array = str.split(' '); var x = array[0], x1 = array[1], x2 = array[2]; but if input given like:
stack 12 3
overflow 13 4
i need 12 stack1 ,3 stack2 , 13 overflow1 , 4 overflow2. hope information enough.
