Using javascript to get form input name and value pairs

Copy linkTweet thisAlerts:
Sep 11.2010

I’m trying to figure out how I can create javascript code in a bookmark that pulls the names and values from the form inputs in a loaded document.

In addition it would also be nice if the code knew which form has focus and just pulled the input names and values from that form.

I’ve been trying to figure it out, but the only portion I could get to work so far is:

[CODE]javascript:(document.write(document.forms[0].elements[0].name))[/CODE]

I don’t really know where to go from here. Writing javascript in a javascript?) seems to be different and beyond my level.

Any help would be appreciated. Thanks.

@Declan1991Sep 12.2010 — Using JavaScript like that is absolutely identical to writing it any other way, except in one little way. Statements that return a value other than null must be wrapped in void.javascript:void(mynum = 10);alert(mynum);

Part of my problem was that I was putting parenthesis where they shouldn't go.

So
[CODE]javascript:(document.write(document.forms[0].elements[0].name))[/CODE]
should be
[CODE]javascript:document.write(document.forms[0].elements[0].name)[/CODE]

Success!
