i'm trying to pass a php defined string with spaces to a javascript function, so that i can append to a query string. However, the function only works when there are NO spaces, and does not even execute when there are spaces -- by testing with alert().

is there a way I can pass strings with spaces into javascript functions, so that i can eventually do an escape(), and then append to my query string? (using alert() in this example)

.php file

<a onClick=showUser('<?php echo $stringwithspaces; ?>')>click here</a>

.js file

function showUser(str)
{
alert (str);
}

if I could only do something like... onClick=showUser(escape('<?php echo $deptname; ?>'))... that would be awesome, but that didn't work. Any help would be much appreciated! Thanks!

• I don’t think the full contents of your PHP file have made it into the question. Could you edit it to get them in there? – Paul D. Waite Commented Dec 21, 2009 at 12:19
• You need to write valid HTML before anything else. – Josh Stodola Commented Dec 21, 2009 at 14:30

The problem is you didn't quote the attribute value. You can leave quotes off of attribute values only if the value doesn't contain spaces, otherwise the HTML processor can't tell when an attribute ends. Even so, it's not remended; you should always quote HTML attributes.

<a href="showUser('<?php echo addslashes($username) ?>')">user</a>

should work. The call to addslashes escapes quotes, which would otherwise cause another problem (ending the attribute or string argument of showUser too soon).

Yes you can you are missing " in you xml attribute field: Each attribute must have a starting and an ending "

myField="blabla ..."

onClick="showUser(escape('<?php echo $deptname; ?>'))"

Try the Unicode escape sequence for a space character, '\u0020'.
