the trouble with arguments

Jan 31st, 2008

I am a Javascript newb, and I am haveing some trouble with my arguments.

 Help with Code Tags 
 javascript Syntax (Toggle Plain Text) 
function openMenu(tableName)	{
document.getElementById(tableName).style.visibility="visible";
}
function openMenu(tableName)	{
document.getElementById(tableName).style.visibility="visible";
}

This is the code i have, and it is working perfectly on the different menus at the top of my screen. The problem i have is with my table IDs, i get the ids from a database using php, and one of them has a space in the centre, so that one doesnt work. This is my php if anything can be changed in either language i would be grateful for any help.

Based on the W3C standards you must encapsulate attribute values in quotes ie, name="hello" is right, name=hello is wrong.
So your echo is breaking the script.
