POINTER CURSORS UPDATE
Whenever a DML statement (INSERT, UPDATE and DELETE) is issued, an implicit cursor is associated with this statement. Programmers cannot control the implicit cursors and the information in it. Implicit cursors are automatically created by Oracle whenever an SQL statement is executed, when there is no explicit cursor for the statement. You can name a cursor so that it could be referred to in a program to fetch and process the rows returned by the SQL statement, one at a time. The set of rows the cursor holds is referred to as the active set. A cursor holds the rows (one or more) returned by a SQL statement. PL/SQL controls the context area through a cursor. Oracle creates a memory area, known as the context area, for processing an SQL statement, which contains all the information needed for processing the statement for example, the number of rows processed, etc.Ī cursor is a pointer to this context area. In this chapter, we will discuss the cursors in PL/SQL. Let’s see output for a particular element on which we are going to hover. This is the example of a combination of multiple cursors going to use in Javascript. Hover the mouse on the text after clicking button to see changed cursor.ĭocument.getElementById("cursor").style.cursor = "wait" Same thing we can use for showing processing cursor. So it will look exactly as shown in the output screen below. This is a second example where we are checking cursor for wait. Here we are hiding cursor from the whole webpage. This can be one for the entire webpage or on a specific selected element from the page. Custom cursor – control-user-cursor: This is the type of cursor in which we are able to change the built-in library by using our own styles and applies cursor on related elements on the hover effect.īelow are the examples of JavaScript Cursor: Example #1.90’s Cursor Move Effects: This type of cursor helps us to create animation along with 6 types of 90’s cursor move effects which is designed using pure JavaScript.Interactive Custom cursors in JS & CSS: This type of cursor helps us with kursojs JavaScript for creating interactive cursors to the webpages.Interactive cursor-dot Effect: With the help of vanilla JavaScript, one can create different effects on the cursor like customizable, interactive effects whenever it’s going to hover on particular elements.Interactive Circle Cursor: This can be used along with JavaScript file called as pointer.js library which is helpful in creating interactive, circular, and customizable as well as many cursors to change already existing mouse pointer.There are multiple ways through which we can use cursor in JavaScript, let’s see all those types one by one in details as follows description:
POINTER CURSORS CODE
It’s also possible to hide cursor on a specific element using code like:.One can able to hide the mouse cursor in JS and CSS throughout the webpage: If we want to hide mouse cursor from the whole webpage then we can do this by using simple code in CSS like cursor: none value.Where value can be auto, all-scroll, cell, col-resize, none, pointer, not-allowed, text, URL, wait, zoom-in, zoom-out, etc. One can set different values to the cursor for better effect.So one can choose appropriate cursor name from the list for relevant actions like mouse pointer, link & status, general cursor, resize and scrolling, zooming and many more. In the nameOfCursor defines the different types of cursor which are already available.To use JavaScript cursor in our code we are going to use it with the following syntax: progress: if there is something in progress or working, then it’s used as a progress cursor.not-allowed: if something is not able to do any action then this type of cursor is used.help: For a particular element, if some help is available then this cursor value is used.grab: Whenever we want to show some grabbed data then we use this value to show the cursor.e-resize: This is used to show the edges of the box are going to move east means at right.copy: This cursor type shows that something is to be copied.col-resize: This cursor value is used to show the column is resized horizontally.cell: This is used to show a particular selected element is a cell.auto: By default, auto is used to set cursor value.all-scroll: Whenever we want to show something can be scrolled in any direction then it’s helpful to use all-scroll cursor value.
