hi,

is it possible to have a string variable to contain new lines. i tried
the following but it didnt work:

var_string = '<h1>Title</h1>
<img src="image.gif>
<p>Body text</p>';

i know that html will display the same if i was to write the above
into, for example, a <span> tag but i have a very large amount of html
to be contained inside a variable. what i will do first is design it
in dreamweaver and then cut and paste it. as dreamweaver will
automatically format the code with new lines, for me to contain it
inside a variable i will have to put it all into one line (time
consuming and messy). is it possible to do this or hava a special
symbol to declare a new line (i.e. \n in php).

also, is there a limit to the amount of characters that can be
contained within a javascript string variable? cheers

Suggestion: include the HTML as HTML in an invisible span or div. Then
your string can simply be found with:

var var_string = div.innerHTML;

(Pitfall: innerHTML may not be available on browsers you need to
support.)

\n has the same meaning in javascript. Tip: It is more rewarding and
motivating to discover such things through experimentation.

It has been rumoured IE would choke on strings longer 2000 characters, but I
just tried and all was well even with a variable of 199000 characters.

might try
var_string='<h1>Title</h1>'
+'<img src="image.gif>'
+'<p>Body text</p>';

To do what you ask for, insert \n

To do what you might want, insert <br>

To multi-line write a string variable, this may work but is deprecated
var_string = '<h1>Title</h1>_
<img src="image.gif>_
<p>Body text</p>' ;

This is inefficient :
var_string = '<h1>Title</h1>'
var_string += '<img src="image.gif>'
var_string += '<p>Body text</p>' ;

This is effective :
var_string = '<h1>Title</h1>' +
'<img src="image.gif>' +
'<p>Body text</p>' ;

And it is still missing the " at the end of the image.gif, and doing
string concatenation across several lines like that won't put the
formatting into the source. \n will add a new line to the output:

var_string='<h1>Title</h1>\n<img src="image.gif">\n<p>Body text</p>';
