is this code outrageously wrong, its supposed to visit each address in the array and tell if theres a ping response

Question

var a="167.192"

function address(){
for(x=0;x<255;x++){
for(y=0;y<255;j++){
document.write(a+"."+x+"."+y
}
}
return= addresses
}
var addresses [

/* do i really have to copy and paste all those addresses in this array or can i just put either the previous functions name or its return? */
]

var b= 0
while(b<array.length){
window.location= address().return
}

Answer 1

The first time you write a variable in javascript, you always need to include "var". You may need to do it again if the variable is only defined within a certain function/loop but you want to use a variable of the same name again outside of the function/loop.

In your code, just add var to the loops:

for (var x = 0; x < 255; x++)
//note: x will only exist within the loop

Answer 2

your second for loop increments j instead of y. Also can you declared var x and y?

Answer 3

o, lol the j was a typo...and x and y ecist as zeros, do they not?
