Create wizard using tab in EJ2 TypeScript Tab control
16 Jun 202324 minutes to read
Tab items can be disabled dynamically by passing the index and boolean value with the enableTab method and also passing index or HTML element to select an item from the tab using select method.
In the below Wizard sample, each Tab is integrated with required components to complete the reservation. Each field is provided with validation for all mandatory option to proceed to next tabs. Using Tab item’s template property the components are added into content.
/* Initializing Tab with header and contents bind to template div for adding other components */
tabObj = new Tab({ heightAdjustMode: 'None', height: 390, showCloseButton: false,
selecting: tabSelected,
items: [
{ header: { 'text': 'New Booking' }, content: '#booking' },
{ header: { 'text': 'Train List' }, content: '#selectTrain', disabled: true },
{ header: { 'text': 'Add Passenger' }, content: '#details', disabled: true },
{ header: { 'text': 'Make Payment' }, content: '#confirm', disabled: true }
]
});
tabObj.appendTo('#element');Create the following contents for each tab in the wizard.
-
Search tab:
Created with DropDownList to select the source, destination and type of ticket. A DatePicker for choosing the date of journey. -
Train tab:
Based on the selected start and end point, populated Grid with random list of available seats and train list. Initially define the columns and row selected event for validating, after the source and destination chosen update the dataSource for the Grid. -
Passenger tab:
A table with Textbox, Numeric, DropDownList for adding passenger name, age, gender and preferred berth/seat. Add validation on entering passenger details to proceed. -
Payment tab:
Calculate the ticket cost based on location, passenger count and ticket type. Generate data for Grid with passenger details, train number and ticket cost summary.
You can go back on each tab using buttons available in it and tabs are disabled to navigate through tab header click actions. Once you end the wizard all the data get cleared and wizard goes back to starting tab.
