How to find the value of visibility

[sumon177]

How can I find the value of visibility...I am trying do following..
if(document.getElementById("or").style.visibility=="visible")...it does not work.

Thanks

Has it been explicitly set using a style="visibility:visible" on the element or document.getElementById("or").style.visibility="visible" in javascript? If not it's probably null. (Note: Setting it in a <style> block doesn't always set it either.)

Its been set up like....
document.getElementById("or").style.visibility="visible"

Sooooo, if you do a:


alert("|"+document.getElementById("or").style.visibility+"|");


you get what???

That should work. I used something similar to toggle the forums list on the main page of this site. Actually it was the display property, but that shouldn't matter.

Here's the function I just mentioned
var theseDivs = document.getElementById(ID).childNodes;



for(var j=1; j<theseDivs.length;j++) {
if(theseDivs[j].className=='tab_inner') {
if(theseDivs[j].style.display=="block") {
theseDivs[j].style.display="none";
document.getElementById(ID).firstChild.style.backgroundImage='url(/img/plus.gif)';
}
else {
theseDivs[j].style.display="block";
document.getElementById(ID).firstChild.style.backgroundImage='url(/img/minus.gif)';
}
}
}
}

I found the problem..that JS method code(document.getElementById("or").style.visibility="visible") was functioning after the if statement. Now I am calling the fuction inside the fuction with the if statement.

Thansk a lot guys....
