Is Null or Not an OBJECT

[Michael Hill]

I created this select dynamically in a page like:

var j=4;
mySELECT = document.create Element("SELECT ");
mySELECT.name = "MEMBER" + j;
mySELECT.onclic k = function (evt) { alert(this.name ); }
myOPTION = document.create Element("OPTION ");
myOPTION.value= "1";
myTEXT=document .createTextNode ("first");
myOPTION.append Child(myTEXT);
mySELECT.append Child(myOPTION) ;
myOPTION = document.create Element("OPTION ");
myOPTION.value= "2";
myOPTION.select ed="true";
myTEXT=document .createTextNode ("second");
myOPTION.append Child(myTEXT);
mySELECT.append Child(myOPTION) ;
myTD.appendChil d(mySELECT);

But then when I try to access it with either:

document.update .elements['MEMBER4'].value

or

document.update .MEMBER4.value

or

document.update .elements['MEMBER4'].options[document.update .elements['MEMBER4'].selectedIndex].text;

I get blah, blah ... 'is null or not an object'.

I can see the object on the page and when I click on it I get the alert
message showing the name is "MEMBER4".

I am stumped why I am getting this message. Something must not be right.
Could it be that it is not getting created in the form "update"? I need
to have it created there.

Any help is appreciated.

Naw, it is being created in the <form> heirarchy.....

Re: Is Null or Not an OBJECT

try document.all.it em("MEMBER4").v alue

if this works, then it obviously isn't being created inside the form
"update"
:o)

And then it only works in IE and perhaps Opera, since document.all is
IE-ism.

Re: Is Null or Not an OBJECT

lol* i didn't give you that to solve yer problem, i gave it to you to check
whether you CAN find the object

try this, add an ID attibute to it and call it by the getElementById (not
IE-ism) method

Now you are making the mistake of assuming I am the one that posted the
original question. Perhaps if you spent as much time trying to learn
what you were doing, you would not be wasting as much time giving
incompetent answers.

When I changed this:

mySELECT.name = "MEMBER" + j;

to this:

mySELECT.id = mySELECT.name = "MEMBER" + j;

if worked fine.

Thanks for the reminder.
