Reset to default 6

When you use document.getElementById() you already know the id.

You could even do this:

function hidediv()
{
  alert("divtobehide");
}

It doesn't make much sense the way you have written the code. Maybe there's a conceptual error (misunderstanding) on how getElementById() works?

If you want to manipulate a DOM object of which you already have the ID you can do this:

function hidediv(nodeId)
{
  var node;

  node = document.getElementById(nodeId);
  node.style.display = "none";
}

In the HTML specify the related id:

<img src="index.jpg" id="imgid" onclick="hidediv('divtohide')" style="float:right;">

This way you can reuse the function and criss-cross <img> and <div> nodes.

try this

alert(document.getElementById("imgid").parentNode())

OP is asking to get clicked element's div ID, not how to hide an element. Once you get an element, you can use dot notation to access it's properties. Here is how you do it:

var element = document.getElementById('id');
console.log(element.id);

Now, if you want an element's parent. It's a bit different. Pass the element itself as parameter of your function by adding "this" in between the parantheses.

<img src="index.jpg" id="imgid" onclick="hidediv(this)" />

Change the function header to allow the passing of the parameter. You can name it however you want althoug I suggest "sender".

function hidediv(sender){}

Now inside the function, you can get the sender's parent by using the dot notation .parentNode. This will make your function work, whatever image is clicked or whatever the div's id. Be wary tho this only gets the immediate parent of the sender.

Take a look at this: http://jsfiddle/TASmS/

Here is simple solution.

function reply_click(clicked_id)
 {
    alert(clicked_id);
 }
onClick="reply_click(this.id)"
