javaScript

hello,
i have this webpage that is semi big, and i'm writing some javascript to fix it up and make it more streamline. however, i don't know the path of some of my html objects.

for example

Code:

<input type = "radio" value="0" name="myradio">Radio

<select name = "sel" id ="sel" >
<option name="1">Option 1 </option>
<option name="2"> Option 2</option>
</select>

i want to add:

Code:

<input type = "radio" value="0" name="myradio" 
onclick = javafunct(document.myformName.sel)>Radio

but i get errors, saying that "document.myformName.sel is null or not an object.

however when i do:

Code:

<select name = "sel" id ="sel" onchange(this)>
<option name="1">Option 1 </option>
<option name="2"> Option 2</option>
</select>

it works fine,
so my question is, can print out the DOM path of "this"? (which my select menu)

i think that the select object is nested somewhere, but its hard to tell, and i didn't write the webpage, i'm just fixing it up for someone...

thanks,

this is the *current* object, you can use it to manipulate things around it (if I'm understanding the question correctly). If you want to get to some specific element of your page, then try using document.getElementById to retrieve the object with a specific id (assuming you gave it an id). getElementsByTagName and getElementsByName are also helpfull.

Btw, always make sure to quote your JavaScript functions. It should be:

Code:

onclick='myfunc("param1","param2");'

Were I you, I would use the excellent Mozilla DOM Inspector (see the Tools menu). It even has a Javascript view!
