line breaks in alert box from html script

in an alert \n should work:

Code:

alert('foo\nbar');

and of course can you use a variable, JavaScript is a programming language so you would be lost without that possibility.

Many thanks gits but that doesn't work, the problem is how html reads the script passed over from js - but I've now sussed it (after a few hours) -- the \n needs an escape in front of it ie \\n.
Posted for others is the part of document.write that applies (note the quotes):
"<table><tr><td ><a href onclick=alert(' Some list\ \nhere')>The list</a></td></tr></table>".
Try this in a table created from js and click on the words 'The list'
Thnx to all who looked at it for me

basically the following is not really valid:

Code:

<a href onclick=alert('Some&nbsp;list\\nhere')>

and should be:

Code:

<a href onclick="alert('Some&nbsp;list\nhere')">

is the shown code a snippet in a php script? in case it is then in fact it will turn out as:

Code:

<a href onclick=alert('Some&nbsp;list\nhere')>

later when the page is rendered. but attribute values should be enclosed in (double-) quotes

Hi gits, I've now replaced the text(between the 's in the alert box) with a variable. Had problem getting this to work until I entered the variables in the <script> section of the page <head>. I couldn't use double quotes in your example because all this snippet was inside a set of doubles to produce a row of a table. The project is for in-house so whatever works without bringing down the ceiling should be OK. The \\n works in the text variable and (bonus)   is not needed: eg var strText = 'amounts\\n\\n1 st\\nDue - $120.37'
Once again many thanks
