For reference in case I lose it later. Thanks to E4X, we can now have multi-line strings similar to HEREDOC syntax (although quite a bit more verbose):
var string = (<r><![CDATA[
The text string goes here. Since this is a XML CDATA section,
stuff like <> work fine too, even if definitely invalid XML.
]]></r>).toString();
This syntax works fine on Greasemonkey too (trunk, 2005-10-ish, GM 0.6.3). Should be useful, especially in combination with stuff like the add CSS “pattern”…
I can’t believe how much pain it is to try to get raw text in here… This is just a bit silly. Basically had to go turn off the WYSIWYG editor cocmpletely. I guess I should try doing things in an external editor instead…

Do you know any other ways which work with IE6,7 ?
2007-07-06 at 2:33 pm |
Sorry, no ideas there. IE6 is old enough that if there had been a way, I’d assume smarter people would have found it 🙂

I used something like follows and it works both in IE and FF.
…. more content
var page = document.getElementById(“page_html”).innerHTML;
document.write(page);
2007-11-13 at 2:21 am |
Sorry, code should be like:
.... more content
var page = document.getElementById("page_html").innerHTML;
document.write(page);
2007-11-13 at 2:44 am |
<script id=”page_html”>
<html>
<body>
There is some content
</body>
</html>
</script>
<script>
var page = document.getElementById(“page_html”).innerHTML;
document.write(new_page);
</script>

it doesn’t work in IE though 😦
Anybody got something similar for IE?

[…] ECMAScript for XML (E4X) you can simulate HEREDOC in Javascript which is great when blasting HTML or CSS. Having to escape strings and join multi-line strings is […]

Incredible, this is just what i looked for.
2008-06-09 at 7:16 pm |
That should be fine:
There is some content
Here is the content above duplicated via JS:
var page = document.getElementById(”page_html”).innerHTML;
document.write(new_page);

Sorry, html tags were filtered out by wordpress in previous comment.
That should be fine:
<html>
<body>
<div id=’page_html’>
There is some content
</div>
Here is the content above duplicated via JS:
<script type=’text/javascript’>
var page = document.getElementById(”page_html”).innerHTML;
document.write(new_page);
</script>
</body>
</html>

regarding the hidden div method, lets say I want an html fragment like:
VALUE
Wouldn’t that prevent my code from validating?
2008-07-30 at 11:58 am |
maybe the validation is only relevant for divs that are actually rendered..

You can also escape the line-carriage like this:
var1 = “line1\
line2\
line3”;
this won’t show up when the html is finally spit out, but it does increase organization.

This one is a life-saver! However, I need a little more help.
Can anyone tell me how to restore the newlines when I display the string as well? I have been able to put the multi-line string from a text file (wrapped with the CDATA stuff at the beginning and end), and am now simply trying to do a string.replace(“\n”, “\n”); in the code but it doesn’t seem to work.
2009-01-22 at 9:51 am |
sorry, the above should have read string.replace(“\n”, “\\n”);
2009-01-22 at 9:52 am |
Hmmf… sorry about spamming this comment space – I’m trying to replace newline characters with an additional br.
Would really appreciate anyone’s help.
2010-03-29 at 2:00 am |
This is a year late, but, new lines in text files aren’t actually “\n”, they’re “\r\n”… take took me a bit to figure out too.
2013-06-02 at 2:50 am |
I know of seven ways to do that.
var myString = function(){/*Hello World
Saluton Mondo
Shall we play a game?*/}.toString().slice(14,-3);
var myString = `Saluton Mondo
Hello World
Shall we play a game?`;
var myString = ().toString();
var myString = “Saluton Mondo \
Hello World \
Shall we play a game?”;
var myString = “Saulton Mondo” +
“Hello World” +
“Shall we play a game?”;
var myString = [“Saluton Mondo”,
“Hello World”,
“Shall we play a game?”].join(“\n”);
Saluton Mondo
Hello World
Shall we play a game?
var myString = document.getElementById(“bogus”).innerHTML;
