Binary to text

I used to know this a year ago, but know its totally out of my head and bugging me.

How do I convert text to binary? Do I have to convert it to ascii first, and if I do, I remember there was a shortcut for text to ascii conversion, but thats all gone now, flushed out of my brain with alcohol.

I need your brains...

mine is in flash...buuuuuuuuuuuuuh to you :p

Right, there's many convertors out there, I was looking for a manual way. Im looking through your source right now argo in the strtobit function, but frankly not understanding it. Sorry, I guess I turned into a thick designer...:(

actually flash does all the work for you:

code:

function strToBin(lqlstr) {

//create and array, each element in the array is a character of the string,

//so if you right "apple" the array is "a,p,p,l,e"

	var charArray = lqlstr.split("");

	var i = 0;

//i go through each element in the array  and call the chartobin function for each element (that means i call the function for each letter

	while (i<charArray.length) {

		charArray[i] = (charToBin(charArray[i]));

		i++;

	}

	return charArray.join("");

}





//take a character as a parameter

function charToBin(lqlchar) {

//get the character code (which is a number) of the letter

	var code = lqlchar.charCodeAt(0);

//here, convert the code (number) to a number with base 2 (binary) and still, use it as a string

//then add 4 0000, just in case, to the beginning of the string (cause the minimum number it will return, is a 4 digit number (but i need 8 digits, for it to be a byte, i believe)

//so, you ll have something like "00001111"

//or "000012345678"

	var bincode = "0000"+code.toString(2);

	//here, i just make sure that the return code has 8 digits

//so if it is "00001234567" it will be cut to "01234567"

	bincode = bincode.substr(-8, 8);

	return bincode;

}

im not really good at explaining stuff :p
