JavaScript dataView.getUint16() Method
Below is the example of the dataView.getUint16()() Method.
- Example:
javascript
<script> var buffer = new ArrayBuffer(20); var dataview1 = new DataView(buffer, 0, 10); dataview1.setUint16(1, 12); document.write(dataview1.getUint16(1)); </script> |
- Output:
12
The dataView.getUint16() is an inbuilt function in dataView which is used to get an unsigned 16-bit integer at the specified location i.e, at byte offset from the start of the dataView.
Syntax:
dataView.getUint16(byteOffset)
Parameters: It has parameter byteOffset which is offset in a byte and it says from the start of the view were to read the data.
Return value: It returns unsigned 16-bit integer.
Example 1:
Input: dataview1.setUint16(1, 56); document.write(dataview1.getUint16(1)); Output: 56
Example 2:
Input: dataview1.setUint16(1, Math.PI); document.write(dataview1.getUint16(1)); Output: 3
JavaScript code to show the working of this method:
Code #1:
javascript
<script> // Creating buffer with size in byte var buffer = new ArrayBuffer(20); // Creating a view var dataview1 = new DataView(buffer, 0, 10); // put the data 56 at slot 1 dataview1.setUint16(1, 56); document.write(dataview1.getUint16(1) + "<br>" ); </script> |
Output:
56
Code #2:
This function convert the float value of PI from 3.14 to 3
javascript
<script> // Creating buffer with size in byte var buffer = new ArrayBuffer(20); // Creating a view with slot from o to 10 var dataview1 = new DataView(buffer, 0, 10); // put the value of PI at slot 1 dataview1.setUint16(1, Math.PI); document.write(dataview1.getUint16(1) + "<br>" ); </script> |
Output:
3
Code #3:
When there is no data to be stored, then it returns zero (0).
javascript
<script> // Creating buffer with size in byte var buffer = new ArrayBuffer(20); // Creating a view var dataview1 = new DataView(buffer, 0, 10); // putting no data at slot 1 dataview1.setUint16(1); document.write(dataview1.getUint16(1) + "<br>" ); </script> |
Output:
0
