The dataView.getInt8() is a method in dataView which is used to get an 8-bit integer in the byte at the specified location from the start of the dataView.
Syntax:
dataview.getInt8(byteOffset)
Parameters: It has the parameter byteOffset which is offset in a byte and it says from the start of the view where to read the data.
Return value: It returns 8-bit signed integer value.
Below are examples of the dataView.getInt8()() Method.
Example 1:
javascript
var buffer = new ArrayBuffer(16); var dataview1 = new DataView(buffer, 0, 4); dataview1.setInt8(0, 12); console.log(dataview1.getInt8(0)); |
Output:
12
Example 2:
Javascript
dataview1.setInt8(0, 123); console.log(dataview1.getInt8(0)); |
Output: 123
Example 3:
Javascript
dataview.setInt8(3, 45); console.log(dataview.getInt8(3)); |
Output: 45
Example 4:
javascript
// Create buffervar buffer = new ArrayBuffer(16);// Create one viewvar dataview1 = new DataView(buffer, 0, 4);// put the data at slot 0dataview1.setInt8(0, 123);console.log(dataview1.getInt8(0) + "<br>");// create another viewvar dataview2 = new DataView(buffer, 1, 2);// put data at slot 1dataview2.setInt8(1, 45);console.log(dataview2.getInt8(1)); |
Output:
123 45
Example 5:
Javascript
// Create buffervar buffer = new ArrayBuffer(16);var dataview = new DataView(buffer, 0, 10);// put data at slotsdataview.setInt8(0, 12);dataview.setInt8(1, 23);dataview.setInt8(2, 34);dataview.setInt8(3, 45);dataview.setInt8(4, 67);dataview.setInt8(5, 78);dataview.setInt8(6, 89);dataview.setInt8(7, 90);dataview.setInt8(8, 123);// print the value using getInt8 method that// prints the first 8 intconsole.log(dataview.getInt8(0);console.log(dataview.getInt8(1);console.log(dataview.getInt8(2);console.log(dataview.getInt8(3);console.log(dataview.getInt8(4);console.log(dataview.getInt8(5);console.log(dataview.getInt8(6);console.log(dataview.getInt8(7);console.log(dataview.getInt8(8)); |
Output:
12 23 34 45 67 78 89 90 123
