Webmaster Forum / HTML, CSS, Scripts / JavaScript / July 2007object expected - huh?
Hi, I'm trying a simple thing, trying to call this: <script language="text/javascript"> <!-- function rating(){ alert(document.Form.00N30000000h5OG.value); var capital=document.Form.00N30000000h5OG.value; // alert(capital); // document.write("rating: "); } //--> </script> out of this: <input id="00N30000000h5OG" value="<? echo $_POST['00N30000000h5OG']?>" maxlength="20" name="00N30000000h5OG" size="20" type="text" onkeyup="javascript:rating()"/> But it returns "object expected" and i have no clue why... been looking around for a while but haven't found anything. Help would be kindly appreciated! Thank you!

It doesn't belong there. David Mark said: >> Hi, >> [quoted text clipped - 17 lines] >Get rid of the "javascript:" prefix in the onkeyup handler. It doesn't >belong there. It doesn't hurt anything. The javascript parser considers it to be a statement label which has no special meaning. We haven't seen anything to convince us that the name of the form is actually "Form". Also note that values of the attribute NAME should begin with an alphabetic character. -- <snip> >>> <input id="00N30000000h5OG" >>> value="<? echo $_POST['00N30000000h5OG']?>" >>> maxlength="20" name="00N30000000h5OG" size="20" type="text" >>> onkeyup="javascript:rating()"/> <snip> > Also note that values of the attribute NAME should begin > with an alphabetic character. Only in this case where the NAME attribute is (and should be) the same as the ID attribute. NAME attributes are CDATA (except on META elements where they are NAME tokens) and may contain any sequence of characters "from the document character set" (as the HTML 4.01 specification puts it). ID attributes are ID tokens and so begin with the upper or lower case A-Z. Richard. > David Mark said: >> Get rid of the "javascript:" prefix in the onkeyup handler.

With for this point strictly ECMAScript Ed. 3 conforming script engines, which are known to not exist. > The javascript parser considers it to be a statement label > which has no special meaning. Not true. It has a special meaning in MSHTML, although a seldom-used one, as JavaScript, or rather JScript, is its default scripting language. > We haven't seen anything to convince us that the name of the > form is actually "Form". Pluralis maiestatis? DID? Speak for your humble self only, please. > Also note that values of the attribute NAME should begin with > an alphabetic character. Not true, they may begin with an underscore, too. PointedEars  SignaturePrototype.js was written by people who don't know javascript for people who don't know javascript. People who don't know javascript are not the best source of advice on designing systems that use javascript. -- Richard Cornford, <f806at$ail$1$8300dec7@news.demon.co.uk> > Hi, > [quoted text clipped - 14 lines] > maxlength="20" name="00N30000000h5OG" size="20" type="text" > onkeyup="javascript:rating()"/> Try: alert(document.forms["00N30000000h5OG"].value); Mick > But it returns "object expected" and i have no clue why... been looking > around for a while but haven't found anything. > Help would be kindly appreciated! > Thank you! > Ron |
