Hey there,
Any idea about the following problem ?
The following code for the ExtractDataFromXmlTag constructor works
fine.
oXmlDoc is a XML document (;o) and aTagArray an array of some tags of
this document. There are some
additionnal methods in this class but nevermind.
var ExtractDataFromXmlTag = Class.create();
ExtractDataFromXmlTag.prototype = {
initialize : function (oXmlDoc, aTagArray) {
this.xmldoc = oXmlDoc;
this.tagArray = aTagArray;
this.childArray = {};
for each (tag in this.tagArray) {
this.childArray[tag] =
this.xmldoc.getElementsByTagName(tag); };
return this.childArray;
},
...
};
The following code don't works ... it returns error: "this.xmldoc
has no properties"
(inside the loop).
var ExtractDataFromXmlTag = Class.create();
ExtractDataFromXmlTag.prototype = {
initialize : function (oXmlDoc, aTagArray) {
this.xmldoc = oXmlDoc;
this.tagArray = aTagArray;
this.childArray = {};
this.tagArray.each ( function(tag) {
this.childArray[tag] =
this.xmldoc.getElementsByTagName(tag); });
return this.childArray;
},
...
};
I'm pretty sure this is a scope problem but I can't figure it out.
Another exemple:
var maxNbChild = this.tagArray.max (function (tag) { return
this.childArray[tag].length;});
returns "this.childArray has no properties"
Enabling Firebug (in FF 2.0.0.2) I can see that that "this" object has
changed, but I don't know
if this is simply a side effect.
Regards
Claude
