    <p><strong>In terms of efficiency,</strong></p> <p>what's the fastest and most standard way to tweak a function in javascript?</p> <p>Plugin-style coding would be like this.</p> <pre><code>; (function ($, window, document, undefined) { var pluginName = "SoketManager", dataPlugin = "plugin_" + pluginName, settings = { target: this, width: 350, height: 150, theme: 'default' } var Plugin = { // instance... } Plugin.prototype = { connect: function() { //something. }, disconnect: function() { //something. }, sendmessage: function() { //something... }, etc: function() { } //etc2: function() ....... } $.fn[pluginName] = function (arg, contents) { var args, instance; if (typeof arg === 'string' &amp;&amp; typeof instance[arg] === 'function') { args = Array.prototype.slice.call(arguments, 1); return instance[arg].apply(instance, args); } </code></pre> <p>And using global variable would be like this..</p> <pre><code>var SocketManager = { sock: '', connect: function () { var stdInfo = new JSONClientParameters(); var socket = io.connect('http://192.168.1.39:3000', { query: stdInfo.toGetString() //'reconnect': true, // 'reconnection delay': 500,//default 500 //'max reconnection attempts': 10 }); kdbSocketManager.ksock = socket; socket.on('connect', function () { alert('successfully connected to the database!!'); }); }, disconnect: function () { this.ksock.disconnect(); }, sendMessage: function (pMsg, pTargetId) { this.ksock.emit('sendMessage', { msg: pMsg, targetId: pTargetId }); }, </code></pre> <p>I see no point in coding like the plugin-way. Is it much more simple and easy to read to code like the latter one? could somebody explain this in detail? </p>

    2. COjQuery plugins allow you to share the same global object, and enforce a standard structure. Really though, your second code example doesn't have any DOM manipulation code - why would it need to be a jQuery plugin in the first place?

    3. COThis is just an example code. forget about the inside codes. please look at the code style instead. I can call the connect method by typing SocketManager.connect() and $.selector.SocketManager('connect'). as I see, the former one is much more simpler... but There's gotta be a reason for doing like that. That's what I'm curious about.

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).
