Introduction

We can have auto complete facility available to us in Widgets design. But To enable auto complete we have to use AJAX Technology. it Suggest possible label names as users are typing.


Use When

Auto complete is always part of a Form. It is also often used by Railway booking pages where the destination needs to be selected. Indian Railway Mobile Application uses this functionality.In all cases, the set of possible values and the potential values can help the user to do their task quicker.


How

When users have entered the first character, the application starts creating matches with the whole set available in the database and its get it through AJAX xmlhttprequest. Those matches are then directly shown underneath the edit box. The user can select the desired value once it has been spotted by using the cursor.


Why

Auto complete helps users to locate the desired item in less steps than would be needed to enter the entire label.
