The file name becomes editable, enabling you to modify the name. Name the file autocomplete, then click Enter. Double-click the new autocomplete. Replace the file's existing code with the following script. You may create such a file to see the final result of the search. A sample of the file is included in the sample application.
As you can see, there is nothing really new you need to learn to write server-side code for Ajax processing. But we had to compromise with a few serious drawbacks of that process including converting PDF pages into image snapshot and increasing file size.

You want to keep a periodical, automatic backup of your database. And, for safety, you are thinking to keep these backups to a preferably free cloud storage.

Select2 is one of the most popular select list plugin for jQuery. Validation can be performed done as the user fills in a form without submitting it. This can be achieved using auto completion. The words that the user types in are submitted to the server for processing.
The server responds with keywords that match what the user entered. It can be used to populate a dropdown box depending on the value of another dropdown box Data can be retrieved from the server and only a certain part of a page updated without loading the whole page. This is very useful for web page parts that load things like Tweets Commens Users visiting the site etc. Our application will have a text box that users will type in the names of the framework.
Step 1 Creating the index page Index.The two main ways are:. Learn how your comment data is processed. Add a require statement to the top of the class to specify that the class requires the Composer.
