Comparing Two Password Strings

[Nicky]

I have not done any programming in years adn someone asked me this today:
"I wanna compare two password strings.
I don't think I can use
IF (pass1 == pass2) equal to
because they are not numerical I certainly cant use
IF (pass1 <> pass2) not equal to
so how do I check that pass1 is the same as pass2."

What lanaguage are you refering to?

Hi Nicky The first one is correct!

var myString="hello"
if("hello"==myString){
staments to execute if true!
}
else{
statments to execute if false!
}

Sorry I didnt completly read your post! It should compare them both the same if its a string, number, or boolean!

var myString=parseInt(20,10);
if(20==myString){
staments to execute if true!
}
else{
statments to execute if false!
}

var myString=true;
if(true==myString){
staments to execute if true!
}
else{
statments to execute if false!
}

Hi,

As poop_shoot implies, comparision is virtually the same regardless of primitive type. So,

if (pass1 == pass2)

is correct. If you are having a problem with that -- and the code you posted is the code you used -- it is because "IF" is not the same as "if".

poop_shoot:

var isOK = true;
 if(isOK)
 {
   statements to execute if true! 
 }
 else
 { 
   statements to execute if false! 
 } 

You don't need to compare booleans.

  var isOK = false;
  if (! isOK)
  {
	statements for false condition
  }

like they said,
if (pass1 == pass2) {}
is correct.

if you want to see if passwords are not the same, use
if (pass1 != pass2) {}

this works with numbers, strings, etc.

var pass1 = "test";
var pass2 = "test";
if(pass1 == pass2){
alert("ok");
}else{
alert("not ok");
}
