Re: cloneNode() not getting script tag content

With the script tags I am filling out a javascript associative array:

						   ID:   "IDATE0VIDAUE0V4",
						   Size: "3",

						   Length: "3",
						   minInclusive: "",
						   maxInclusive: "",
						   Pattern: "[A-Z0-9]{3}",
						   Enumeration: ""};
				</script>


With the sID I am also able to reference the appropriate index of the
array.  The array contains information that I use for validating the
input.  Once I have a copy of the element, I can use the RegEx replace
to make all of the id's and the javascript (the array) unique.

But if that array (that looks like a JavaScript object to me) is a global variable then simply manipulate it with your code, don't try to rely on DOM node cloning to manipulate/copy JavaScript data structures you control yourself.

I guess the bottom line is that I need some way to copy the elements I
need without doing it by reference (because then when I make changes to
the copied element the changes also go into the element I copied from).


I have tried to use a copy function like this:

function copy_obj(o) {
    var c = new Object();

    for (var e in o) {
      c[e] = o[e];
    }
    return c;
}


But you can do e.g.

var fieldData = {};
fieldData["IDAEA1VIDAFA1V4"]
						= {
						   DivID: "sic_code_4sic_code_or_filing_number",
						   ID:   "IDATE0VIDAUE0V4",
						   Size: "3",
						   Type: "xsd:string",
						   Enum: "false",
						   minLength: "",
						   maxLength: "",
						   Length: "3",
						   minInclusive: "",
						   maxInclusive: "",
						   Pattern: "[A-Z0-9]{3}",
						   Enumeration: ""};

function copy_obj(o) {
    var c = new Object();

    for (var e in o) {
      c[e] = o[e];
    }
    return c;
}

fieldData['newId'] = copy_obj(fieldData["IDAEA1VIDAFA1V4"]);
fieldData['newId'].ID = 'newId';

As said, I would not mix your script data structure manipulation with DOM manipulation. If you simply keep track of any stuff in fieldData then your script can always add properties there and manipulate subproperties without any need that the browser supports cloning inline script elements and executing the cloned code when the cloned script element is being inserted into the document. That approach is a rather fragile.
