We've got data(), how about a method()?

in Developing jQuery Core • 11 years ago

Perhaps a future version could incorporate something akin to the following? (I.e. something more native than the hack into the data() space that the following employs.)

Regards,
GD

(function($){
var NAMESPACE = 'method_';
$.fn.method = function( name, subroutine ){
if( typeof subroutine == 'function' )
return this.data(NAMESPACE + name, subroutine);
else
//No return so can fire in an href
this.each(function(){
$(this).data(NAMESPACE + name).apply(this, []);
});
};
})($);

Or better yet, see below. You guys are better at overloading so I trust you'll figure a way to remove the switch statement :-)

(function($){
$.fn.method = function( type, name, rest ){
switch( type ){
case 'set':
//Set the method for each.
return this.data('method_' + name, typeof rest == 'string' ? new Function(rest) : rest);
case 'get':
//Run the method and return its result set, as an array if more than one in this.
case 'run':
//Run the method but return this for continued chaining.
var args = [];
for( var i = 2; i < arguments.length; i++ )
args.push(arguments[i]);
if( type == 'run' )
return this.each(function(){
$(this).data('method_' + name).apply(this, args);
});
else if( this.length == 1 )
return this.data('method_' + name).apply(this.get()[0], args);
else if( this.length > 1 ){
var all = [];
this.each(function(){
all.push( $(this).data('method_' + name).apply(this, args) );
})
return all;
}
else
return this;
default:
alert('Unknown method action: ' + type + ' on ' + name + '.');
return this;
}
};
})($);
