From Test.html I include a test.js that runs function d(). This function has a parameter a string that might contain “new line” characters (10 in ASCII), as per example below. However, when I am debugging this function, vars s and data include all characters except the new line, i.e., they contain string “HelloWorld” (length 10) instead of “Hello[charNewLine]World” (length 11).

Is there a way to pass a string with new line characters as parameter to a function in Javascript? Thank you.

test.js

function d(s) 
{
    var data = (s + "").split("");
    var dataLength = data.length;
    var t = [dataLength],n;

    for(n=0;n<dataLength;n++)
    t[n]=data[n].charCodeAt(0);
}
d("Hello\
World");

    d("Hello\
World");

    contains a "line continuation".

    The language specification says

    The String value (SV) of the literal is described in terms of character values (CV) contributed by the various parts of the string literal.

    …

    The SV of LineContinuation :: \ LineTerminatorSequence is the empty character sequence.

    which means that it contributes no characters to the value of the string literal.

    To embed a newline in a string, just use \n as in

    d("Hello\nWorld")
