    <p>The jQuery documentation recommends having default values for a plugin, and allowing the user to send any custom values. To do so, the user passes the custom values as an object using <code>$.fn.tooltip = function( options ) {}</code>. Makes sense to me.</p> <p>Then later in the same article, they recommend collecting all of the plugin's methods in an object literal called methods, and calling a given method by passing the string name of the method such as <code>$.fn.tooltip = function( method ) {}</code>.</p> <p>So, am I sending options or method to <code>$.fn.tooltip = function( ? ) {}</code>?</p> <p>Also, why is the methods object declared outside the plugin?</p> <p>SOURCE: <a href="http://docs.jquery.com/Plugins/Authoring#Defaults_and_Options" rel="nofollow noreferrer">http://docs.jquery.com/Plugins/Authoring#Defaults_and_Options</a></p> <pre><code>(function( $ ){ $.fn.tooltip = function( options ) { // Create some defaults, extending them with any options that were provided var settings = $.extend( { 'location' : 'top', 'background-color' : 'blue' }, options); return this.each(function() { // Tooltip plugin code here }); }; })( jQuery ); </code></pre> <p>SOURCE: <a href="http://docs.jquery.com/Plugins/Authoring#Plugin_Methods" rel="nofollow noreferrer">http://docs.jquery.com/Plugins/Authoring#Plugin_Methods</a></p> <pre><code>(function( $ ){ var methods = { init : function( options ) { // THIS }, show : function( ) { // IS }, hide : function( ) { // GOOD }, update : function( content ) { // !!! } }; $.fn.tooltip = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { $.error( 'Method ' + method + ' does not exist on jQuery.tooltip' ); } }; })( jQuery ); // calls the init method $('div').tooltip(); // calls the init method $('div').tooltip({ foo : 'bar' }); </code></pre>

    1. COAfter further review, it appears that settings should be defined in the init method. I am still curious why methods is defined outside of the plugin.

    2. COEverything inside the `(function( $ ){...})(jQuery);` is part of the plugin, or at least should be. `$.fn.tooltip = function( method ) {};` is simply a way to combine all the methods in `var methods` into one `$.fn` namespace.

    3. COSo, I can't have both $.fn.tooltip = function( method ) {...} and $.fn.otherPlugin = function( method ) {...} in the same (function( $ ){...})(jQuery);?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
