I think the code breaks down

I think the code breaks down when the function does not know what "this" refers to.

In my first response on the thread, I showed you how to pass a particular anchor object (this) to the function nextSibling(elm) - note that "this" (the anchor object) becomes "elm" in the function

Funny thing is that if i dont declare a.onmouseover as a function then when the page loads whatever i want a.onmouseover to do executes as the page loads, but not if i declare it as a function.

If you put the code in without declaring it as a function, it will execute when it loads. If it is a function, the function needs to be called.

If you can post a link to the page, or attach an html file, we can test our solutions...

Hi Decibel,

Yes the

a.onmouseover = function(){
this.nextSibling.style.display = 'block';
}

Does work.

Funny thing is that if i dont declare a.onmouseover as a function then when the page loads whatever i want a.onmouseover to do executes as the page loads, but not if i declare it as a function.

How can i pass parametres into the function if i should do this:

function something(){

}

a.onmouseover = something;

is this acceptable: a.onmouseover = something(a);

The function works, just the setTimeout() does not.

are you saying that this works (without the timer)?

a.onmouseover = function(){
this.nextSibling.style.display = 'block';
}

I do not think your syntax is correct, first of all using a variable like a.onmouseover, secondly when you declare a function as a variable this way, you still need to define the variable(s) being passed to the function eg

var add=function theAdd(a, b) 
{                     
  return a+b;
}                     
alert(add(1,2));           // produces 3
alert(theAdd(1,2));        // also produces 3

(refer to this page).

I would do something like

function name(){
somecode
}

var theelm = name; //not sure if you need the parentheses here or not...

but I am uncertain of the value of assigning the function to a variable

Notice in my example above that I am passing the element object with the mouseover to the function as this/elm

Any other advise appreciated.

you need to define the function properly, add an event listener to your anchor tag, and pass "this" to the function

let's define the function:

function nextSibling(elm){
var timer = setTimeout(elm.nextSibling.style.display = 'block', 1000);
}

now let's set up the anchor

<a href="somevalue" onmouseover="nextSibling(this)">linkcontent</a>

if it's not a real link, I recommend setting the href="javascript:void(0)"
