Navigating the DOM

bazcaz

I am trying to navigate the DOM in Mozilla Thunderbird with a DOM inspector extension and I have identified an element and the node I want to change now its id is priorityCol but when I try to access it like this

document.getElementById("priorityCol").firstNode.nodeValue="false";

says that document.getElementById("priorityCol") has no properties???

Anyone any ideas where may be going wrong the id is definitely right!

Actually, you need to be careful with getElementById. Try this instead ...

if (window.document.getElementById != null)
   myDomObj = window.document.getElementById("priorityCol");
else if (window.document.all != null) 
   myDomObj = window.document.all("priorityCol");

No neither of them worked does it matter what level of the DOM I am at like theres a nice hierarchy from document down to this element in DOM Inspector

Ive sorted it was

window.document.getElementById("priorityCol").getAttributeNode("hidden").value=false;
