====== Edición de subcampos codificados en Catalis ======

A raíz de una [[http://groups.google.com/group/catalis/browse_thread/thread/4c31389fd6c6a857|consulta en el grupo Catalis]], acá va una receta para lograr que un subcampo con valores codificados se pueda editar de manera análoga al subcampo $4 de los campos 700 (relator code). Es decir, que se abra una ventanita emergente que ofrezca la lista de códigos disponibles.


=== XML ===

== frequency.xml ==

<code xml>
<?xml version="1.0" encoding="ISO-8859-1"?>

<relatorCodes>

	<relator code="act" name="Actor" />
	<relator code="adp" name="Adapter" />
	<relator code="aft" name="Author of afterword, colophon, etc." />
	<relator code="ann" name="Annotator" />
	<relator code="ant" name="Bibliographic antecedent" />
	<relator code="app" name="Applicant" />
	<relator code="aqt" name="Author in quotations or text abstracts" />
	<relator code="arc" name="Architect" />
	<relator code="arr" name="Arranger" />
        ...
	<relator code="wit" name="Witness" />

</relatorCodes>
</code>

=== HTML ===

== editCodes.htm ==

<code javascript>
		case "relator" :
			// TO-DO: pensar de qué manera se puede acotar la larga lista, en función del tipo
			// de documento (video, musica, libro, etc.)
			xmlCodes = callingWindowObject.xmlRelatorCodes;
			Codes = xmlCodes.selectNodes("/" + "/relator");
			title = "Relator codes";
			break;
			
		case "frequency" :
			xmlCodes = callingWindowObject.xmlFrequencyCodes;
			Codes = xmlCodes.selectNodes("/" + "/frequency");
			title = "Frequency codes";
			break;
</code>

=== JavaScript ===

== create-field-subfield.js ==

<code javascript>
	// Subcampos cuyos valores se toman de tablas
	if ( "4" == code ) {   // Relator code
		newSubfieldBox.readOnly = true;  // ATENCION: esta propiedad produce un bug al subir/bajar un subcampo $4 vacío
		newSubfieldBox.onclick = function() {
			editCodedData("relator");
		}
		newSubfieldBox.style.fontFamily = "lucida console";
		newSubfieldBox.style.fontSize = "14px";
		newSubfieldBox.style.lineHeight = "17px";
	}
	
	else if ( tag_code.search(/86[34]w/) != -1 ) {  // Frequency code.  Expresión alternativa: /863w|864w/ 
		newSubfieldBox.readOnly = true;
		newSubfieldBox.onclick = function() {
			editCodedData("frequency");
		}
		newSubfieldBox.style.fontFamily = "lucida console";
		newSubfieldBox.style.fontSize = "14px";
		newSubfieldBox.style.lineHeight = "17px";
	}

== aux-windows.js ==

<code javascript>
    function editCodedData(dataElement)
    {
    	if ( dataElement.search(/relator|frequency|f041|f044/) != -1 ) {
    		var srcObject = event.srcElement;
    		var activeCode = srcObject.value;  // TO-DO: evt for mozilla
    		var codeType = "single";
    		var dialogLeft = event.clientX - 70;
    		var dialogTop = event.clientY - 130;
    		var URL = URL_EDIT_CODES;
    	} else if (
    	
    	...
    	
    	if ( dataElement.search(/relator|frequency|f041|f044/) != -1 ) {
    		srcObject.value = newCode.value;
    		//displayPermanentTitle(srcObject,newCode.description.substr(6),40,0);
    	} else {
