JavaScript | dataView.getUint16()

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 byte and it says from the start of the view where to read the data.
Return value: It returns unsigned 16-bit integer.
JavaScript code to show the working of this method:
Example 1:

filter_none

edit
close

play_arrow

link
brightness_4
code

<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>

chevron_right






                        filter_none








Output:


56


Example 2:

This function convert the float value of PI from 3.14 to 3

   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>");

                        filter_none








Output:


3


Example 3:

When there is no data to be stored, then it returns zero (0).

                                    code

   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>
