If I know my INPUT's name, lets say: "realName", how can I get it's ID? (What I mean by ID: e.g. the first element in the first Form is document.forms.elements...)
Thank you, I appreciate it very much. Does anyone like the Smashing Pumpkins?

So you're not talking about the ID attribute?
<input name="bob" id="bobby" />
... And yes, I like Smashing Pumpkins.

no, I'm not talking about the ID attribute. I'm talking about the element Id.
I need this for the Smashing Pumpkins & Zwan Fan Database (http://www.spfd.org). I'm working on a new form.

<input type="text" name="email">
<input type="text" name="password">
<input type="text" name="realName">
now, email has the Id , password  and realName . The thing is, I need to find that out without counting, because I need that to be done automatically as 1) there are many fields and 2) everything will be broken if I hardcode it and add a form input somewhere afterwards.

We usually use the term index about what you spek, not id. But still, I know what you want:
oElements=document.forms[[string formName | number formIndex]].elements,
oIndexByNames[oElements[i].name]=i;I'm afraid you'll have to loop throug the collection and gather the index from it. The way this works, oIndexByNames[[string elementName]] will contain the index of the element with the specified name.

Thank you very much liorean. It works for me even though one has to loop through all of the elements.
