[Javascript] Dollar function for name=

[Terry Riegel]

Phillip,

Thanks for the info. I may be able to still do what I am needing even in that situation. I will have to think it through.

I want to be able to do something like...

$name(n).value="sausage";

In the case of a radio button it would be to set the radio whose name is pizza and whose value is sausage to selected

I will have to think through how this may/may not work. It is really something specific to my thinking and for me to be able to create a convenience function to let me address elements by their name instead of having to create an ID for all of them.

So in the case of an input I am thinking in terms of an "pseudo" object/elment that will let me deal with all the radio buttons as a single object/element.

Any input regarding this will be appreciated.


function $name(n){
 if (typeof n == 'object') {
  return n;
 } else {
  return document.getElementsByName(n)[0];
 }
}

What if my $name() function creates (if it doesn't exist) an object that acts as if $name('pizza') is unique in the same way an ID is unique? And then I could get $name('pizza').value




Terry
