DOM and functions with a return value

alright, i’m checking out the DOM (which has pretty cool methods)

so far i’ve got this: (its simplified)

[code=php]function mnu() {

var thismenu=name;

var mDiv = document.createElement(“div”);

mDiv.getVisibility=function() { thismenu.getVisibility(this); }

alert(mDiv.getVisibility());

document.body.appendChild(mDiv);

}

mnu.prototype.getVisibility=function(div) {
if (div.style.visibility==’none’ || div.style.visibility==’hidden’) {
return ‘hidden’;
}
else {
return ‘visible’;
}
}[/code]

so i attach a function to mDiv, which (should) returns visible or hidden, but it doesn’t, i get an [b]undefined[/b]

but when i put alert boxes in the function itself (in the if-clause), it gives me the correct values

can anybody help me?

grtz

edit: switched visible and hidden

Also in #JavaScript _↴
