The anchorScroll service in AngularJS allows us to jump to the specific HTML element in the web page. When this gets called then it adds [#element-id] on the URL which you can remove with few more line of code.
It has the dependency on $location service for hash the id on the URL and the anchorScroll reads the hashed string and looks for the given id in the web page and jump to it.
The star rating bar allows the user to submit his thoughts on whether the content or product is useful or not. This also gives the administrator a view of how well its item is performing.
It is very common on e-commerce websites.
In this tutorial, I am using the jQuery Bar Rating plugin to display the star ratings on the screen.
Whenever the user changes the rating then send an AJAX request to save the user currently rating status on the MySQL database table with PHP.
The Codeigniter allows us to perform the database action like – select, insert, update, and delete with the minimal script.
The $this->db->update() method is used for update existing record. It takes table name and an array or object as the parameter.
In the demonstration, I am listing the user’s list with the edit option. Show the update form on edit option-click.
You can use jQuery AJAX to autocomplete data on the single or multiple elements when the user search or select value from an element.
It is a better way to allow the users to easily search for data in existing records and get required information e.g. get student details by their id, product details, etc.
In the demonstration, I am using jQuery UI to display a suggestion list and fetch details using PHP from the MySQL database table when a value from the suggestion list gets selected.
