- jQuery Selectors:
The jQuery selectors are used to select parts of a HTML document in a number of interesting ways. The selectors can be used to select say elements based on ids, classes, number etc. For example to select a html element with id="foobar" we can use
$ is the factory function.
- jQuery Event handlers:
jQuery has loads of event handlers associated with each HTML element and gave an introduction in an abstract way.
This will actually select all anchor tags within a
li which is in turn inside a
ul element and alert the value of the anchor.
- jQuery and AJAX:
jQuery has some awesome support for asynchronous request and reply this includes methods like
$getJson method can be used to fetch a JSON file and parse it to obtain data.
Example: In our project DNS - Admin, we have tried to use jQuery's
$get method with mod_python to delete a record when the user selects the zone name and type of record from a drop down list we send an asynchronous
request to fetchrecords.py with zone name and type as parameter and it will return the list of records.
- jQuery Plugins:
Gave an introduction about the variety of plugins available in jQuery like calendar, form validation etc.
