Ext JS 4 - Form Panel With Menubar

The form panel (Ext.form.Panel) class in Ext JS is used for creating form. The default layout of the form panel is anchor. It has lot options for customization, in that one of the feature is menu bar. The following properties are used for including menu into form panel. 

  1. tbar - Top Bar
  2. bbar - Bottom Bar
  3. lbar - Left Bar
  4. rbar - Right Bar

Let's see an example for creating form panel with menu bar.

Ext.define('MyApp.view.PanelWithMenuBar', {
 extend : 'Ext.form.Panel',
 alias : 'widget.panelwithtoolbar',
 layout : 'anchor',
 height : 400,
 width : 400,
 title : 'Form Panel with Menubar',
 url : '/saveform',
 tbar : [{
  text : 'Top-Left Menu',
  menu : [{
   text : 'User',
   menuKey : 'top-left-create-user'
  }, {
   text : 'Document',
   menuKey : 'top-left-create-document'
  }, {
   text : 'Profile',
   menuKey : 'top-left-create-profile'
  }]
 }, '->', {
  text : 'Top-Right Menu',
  menu : [{
   text : 'User',
   menuKey : 'top-right-create-user'
  }, {
   text : 'Document',
   menuKey : 'top-right-create-document'
  }, {
   text : 'Profile',
   menuKey : 'top-right-create-profile'
  }]
 }],
 bbar : [{
  text : 'Bottom-Left Menu',
  menu : [{
   text : 'User',
   menuKey : 'bottom-left-create-user'
  }, {
   text : 'Document',
   menuKey : 'bottom-left-create-document'
  }, {
   text : 'Profile',
   menuKey : 'bottom-left-create-profile'
  }]
 }, '->', {
  text : 'Bottom-Right Menu',
  menu : [{
   text : 'User',
   menuKey : 'bottom-right-create-user'
  }, {
   text : 'Document',
   menuKey : 'bottom-right-create-document'
  }, {
   text : 'Profile',
   menuKey : 'bottom-right-create-profile'
  }]
 }],
 items : [{
  xtype : 'textfield',
  fieldLabel : 'First Name',
  name : 'firstName',
  allowBlank : false
 }, {
  xtype : 'textfield',
  fieldLabel : 'Last Name',
  name : 'lastName',
  allowBlank : false
 }],
 renderTo : Ext.getBody()
});

Here the symbol '→'  is used for moving our menu from left to right side.

Here I have included menuKey attribute, this is custom attribute included for taking handle of the menu actions in controller side. Let's see, how to take a control of form panel and corresponding form menu actions in controller. This is very tricky part when you are in beginning stage and this is my controller code for above view.

Ext.define('MyApp.controller.PanelWithMenuBar', {
 extend : 'Ext.app.Controller',
 init : function() {
  this.control({
   'menuitem[menuKey]' : {
    click : function(menuItem, e, eOpts) {
     switch(menuItem.menuKey) {
      case 'top-left-create-user' :
       console.log('Event related to top-left-create-user');
       break;
      case 'top-left-create-document' :
       console.log('Event related to top-left-create-document');
       break;
      case 'top-left-create-profile' :
       console.log('Event related to top-left-create-profile');
       break;
      case 'bottom-right-create-user' :
       console.log('Event related to bottom-right-create-user');
       break;
      case 'bottom-right-create-document' :
       console.log('Event related to bottom-right-create-document');
       break;
      case 'bottom-right-create-profile' :
       console.log('Event related to bottom-right-create-profile');
       break;
      //Other menukey actions will goes here.....
     }
    }
   }
  });
  this.callParent(arguments);
 }
});

During rendering of an application, the Ext JS will create an object of 'Ext.menu.Item' for tbar, lbar, bbar, and rbar based on its configuration. So I can take a control of all menu items by using xtype and menuKey.

menuitem[menuKey] - Here menuitem refer the xtype of 'Ext.menu.Item' and menuKey is our custom attribute.

The result of above example is given below.

Getting key/value pair from JSON object and getting variable name and value from JavaScript object.

 Hi, I had faced one issue like this. I have an JSON object but I don't know any key name but I need to get the all the key and corresponding value from JSON object using client side JavaScript. Suddenly I wondered whether it's possible or not, after that I had done lot of workaround and finally got this solution. See the below example.    function getKeyValueFromJSON() {     var jsonObj =  {a:10,b:20,c:30,d:50} ;     for ( var key in jsonObj) {       alert( "Key: " + key + " value: " + jsonObj[key]);     }  }  In this example I have created the one json array as string, and converted this string into JSON object using eval() function. Using for-each loop I got all the key value from jsonObj, and finally using that key I got the corresponding value.  Finally I got the alert like this,    Key: a value:10    Key: b value:20    Key...

Simple Login Application Using Spring MVC and Hibernate – Part 1

 I hope developers working in web application development might hear about MVC architecture. Almost all technologies provide support for MVC based web application development, but the success is based on many factors like reusable of the code, maintenance of the code, future adaption of the code, etc..,  The success of the Spring MVC is “ Open for extension and closed for modification ” principle. Using Spring MVC the developers can easily develop MVC based web application. We don’t need any steep learning curve at the same time we need to know the basics of spring framework and MVC architecture. The Spring MVC consists of following important components. 1. Dispatcher servlet 2. Controller 3. View Resolver 4. Model Spring MVC - Overview  The overall architecture of Spring MVC is shown here.  1.

Simple Login Application Using Spring MVC and Hibernate – Part 2

 I hope you have visited my part1 of my tutorial . Let’s see the steps for integrating hibernate framework into Spring MVC. Here I have used MySQL database. I have created one database called “ springmvc ” and created one table called “ user ” with userid, username, password fields.  I have inserted some records into table like this. Step 1: Creating User POJO class.  We need to create a User POJO class for mapping user table. Ok let’s create it. Step 2: Creating hibernate mapping xml file for user class.  In hibernate we need to create hibernate mapping xml file for all domain class for mapping into corresponding database table. Instead of creating xml file you can use annotation for mapping domain class into database table. This is my mapping xml document created for mapping our user domain class into user database table. Step 3: Creating authenticate service class.  The method “verifyUserNameAndPassword” pres...
