The JavaScript DataView.getUint16 function is a built-in method available within the DataView object. This method is utilized for retrieving an unsigned 16-bit integer (also referred to as an unsigned short) from a designated position in the byte buffer.
Syntax
Example
dataview.getUint16(byteoffset)
Parameters
byteoffset: The number of bytes from the beginning of the view indicating the position at which to read the data.
Return value
This function yields an unsigned 16-bit integer value.

Example 1
Example
<script>
//JavaScript to illustrate dataview.getUint16() method
// creating a ArrayBuffer
var pyVisualizer = new ArrayBuffer(8);
// creating a view
var arr = new DataView(pyVisualizer);
// put the value 3.1 at slot 1
arr.setUint16(1,3.1);
document.write("Convert the value 3.1 to :<br><br>");
document.write(arr.getUint16(1));
//expected output: 3
</script>
Output:
Output
Convert the value 3.1 to:
3
Example 2
Example
<script>
//JavaScript to illustrate dataview.getUint16() method
// if there is no data to be stored then it returns Nan
// creating a ArrayBuffer
var pyVisualizer = new ArrayBuffer(8);
// creating a view
var arr = new DataView(pyVisualizer);
// NO Data
arr.setUint16(1);
document.write("If there is no data to be stored, then Output will Be:<br><br>")
document.write(arr.getUint16(1));
//expected output:0
</script>
Output:
Output
If there is no data to be stored, then Output will Be:
0
Example 3
Example
<script>
//JavaScript to illustrate dataview.getUint16() method
// creating a ArrayBuffer
var pyVisualizer = new ArrayBuffer(8);
// creating a view
var arr = new DataView(pyVisualizer);
//We can also use math function like Math.PI
arr.setUint16(1,Math.PI);
document.write("convert the PI value 3.14 to:<br><br>");
document.write(arr.getUint16(1));
//expected output:3
</script>
Output:
Output
convert the PI value 3.14 to:
3
Example 4
Example
<script>
//JavaScript to illustrate dataview.getUint16() method
// creating a ArrayBuffer
var pyVisualizer = new ArrayBuffer(8);
// creating a view
var arr = new DataView(pyVisualizer);
// put the value 40 at slot 1
arr.setUint16(1,40);
document.write("If we give an Integer value then Output will Integer be<br><br>");
document.write(arr.getUint16(1));
//expected output: 40
</script>
Output:
Output
If we give an Integer value then Output will Integer be
40
