I recently asked a question related to jquery's datastore. How to get from an element all the data set using the data method?
I want to better understand the datastore to see if I can fix my problem (data integrity).
I understand the idea of a "numerical pointer to a global hashtable" http://james.padolsey.com/javascript/element-datastorage/
But looking at the jquery source, I'm confused :
data: function( key, value ){
var parts = key.split(".");
parts[1] = parts[1] ? "." + parts[1] : "";
if ( value === undefined ) {
var data = this.triggerHandler("getData" + parts[1] + "!", [parts[0]]);
if ( data === undefined && this.length )
data = jQuery.data( this[0], key );
return data === undefined && parts[1] ?
this.data( parts[0] ) :
data;
} else
return this.trigger("setData" + parts[1] + "!", [parts[0], value]).each(function(){
jQuery.data( this, key, value );
});
},
Why is it using triggerHandler/trigger ? Where can I "see" the data while developing ?
