Webmaster Forum / HTML, CSS, Scripts / JavaScript / March 2006enumerator not working in firefox
The following script works in IE but in Firefox errors with the msg Enumerator is not defined. <html> <head> <meta name="vs_defaultClientScript" content="JavaScript"> <script language="javascript"> <!-- function Recalc(){ var objHidden; var objControl; var objLabel; var n = 0; var sName; var e = new Enumerator(document.getElementsByName("txt")); while(!e.atEnd()){ alert(e.item().value); e.moveNext(); } }; //--> </script> <script id="clientEventHandlersJS" language="javascript"> <!-- function Button1_onclick() { return Recalc(); } //--> </script> </head> <body> <form> <INPUT id="Text5" type="text" name="txt"> <INPUT id="Text4" type="text" name="txt"> <INPUT id="Text2" type="text" name="txt"> <INPUT id="Text3" type="text" name="txt"> <INPUT id="Text1" type="text" name="txt"> <INPUT id="Button1" type="button" value="Button" name="Button1" language="javascript" onclick="return Button1_onclick()"> </form> </body> </html> > The following script works in IE but in Firefox errors with the msg > Enumerator is not defined. Where have you defined it?  SignatureIan Collins. Do I have to define Enumerator, isn't part of the javascript language? I didn't define it for IE... > Do I have to define Enumerator, No. > isn't part of the javascript language? If you mean (Netscape) JavaScript, then no. > I didn't define it for IE... IE uses (Microsoft) JScript. PointedEars ^^^^^^^^^ Who? > The following script works in IE but in Firefox errors with the msg > Enumerator is not defined. Enumerator is defined in Microsoft JScript (primarily to facilitate interaction with other MS software, such as ADO), not in JavaScript. See also <URL:http://pointedears.de/scripts/es-matrix>. > [...] > <script language="javascript"> <script type="text/javascript"> See <URL:http://validator.w3.org/>. > <!-- Nonsense. Search the archives for "comment" and the like. > [...] > var e = new Enumerator(document.getElementsByName("txt")); > while(!e.atEnd()){ > alert(e.item().value); > e.moveNext(); > } While it would be possible to write an Enumerator implementation for JavaScript, the following is easier and works in IE-based UAs, too: var e = document.getElementsByName("txt"); for (var i = 0, len = e.length; i < len; i++) { alert(e[i].value); } See also <URL:http://pointedears.de/scripts/test/whatami#inference>. > }; I doubt there is a point in ending a FunctionStatement with a `;', besides the fact that it is indeed a statement. It rather helps to confuse a standalone FunctionStatement with a FunctionExpression in an assignment. > //--> Nonsense. > </script> > <script id="clientEventHandlersJS" language="javascript"> Utter nonsense. The (X)HTML `script' element has no `id' attribute (by default), nor would it be necessary here. > [...] > <INPUT id="Text1" type="text" name="txt"> type="text" is redundant, that is the default attribute value for this element. > <INPUT id="Button1" type="button" value="Button" name="Button1" > language="javascript" onclick="return Button1_onclick()"> The (X)HTML `input' element has no `language' attribute (by default). Again, the `id' attribute does not strike me as being necessary here. Your indentation sucks. PointedEars Thanks for the info and the sweet criticism. |
