Line break in javascript alert using xajax

How would you encode this variable to include line breaks? I have tried <br>, \n, \r\n it hanges up with all of them.

$myhtml = " Count: ". $row . " Taxid: ". $taxid . "\r\n Legal: " . $sub . " " . $blk . " " . $lot . " \r\nOwner: ".$fname . " " . $lname;

$objResponse->script("alert(myhtml = '$myhtml';")

You must double the backslashes, and the alert call is wrong:

$myhtml = " Count: ". $row . " Taxid: ". $taxid . "\\r\\n Legal: " . $sub . " " . $blk . " " . $lot . " \\r\\nOwner: ".$fname . " " . $lname;

Did not work still no line breakes.  I add another one since google is using it to in the marker popup.
That did not work either.  Any other ideas?

$myhtml = " Count: ". $row . " Taxid: ". $taxid . "\\\r\\\n Legal: " . $sub . " " . $blk . " " . $lot . " \\\r\\\nOwner: ".$fname . " " . $lname;

Two backslashes works for me. What kind of values are in the other variables? You can not have linefeeds or apostrophes.

You have a syntax error in your alert() call. Correct syntax is:


So in the PHP string above, it should be:

$objResponse->script("row=$row;taxid = $taxid;alert('$myhtml');");

works in the alert.  but not in the google marker popup using the same vairable.
I could live with the alert instead of the google marker except that I need to put links in the popup to get additional information if the user chooses. Can that be done in a alert?

No, the javascript alert can not have links, just plain text.

I think the google marker popup is html-based, so \n will not work there, but <br /> should work.

that did it.  thank you! This stuff is comming together, but slowly.  php,xaxjax, javascript, html,filemaker. A lot to learn all at once. I think my biggest problem is mixing syntax between platforms.
