JavaScript | dataView.getUint32()

The dataView.getUint32() is an inbuilt function in dataView which is used to get an unsigned 32-bit integer at the specified location i.e, at byte offset from the start of the dataView.
Syntax:

dataView.getUint32(byteOffset)

Parameters: It has parameter byteOffset which is offset in byte i.e. from the start of the view where to read the data.
Return value: It returns an unsigned 32-bit integer.
JavaScript code to show the working of this method:
Example 1:

filter_none

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.setUint32(1, 56);
  document.write(dataview1.getUint32(1) + "<br>");
     
</script>

chevron_right






                        filter_none








Output:


56


Example 2:

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

   // 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.setUint32(1, Math.PI); 


   document.write(dataview1.getUint32(1) + "<br>");

Output:

Example 3:

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

   var buffer = new ArrayBuffer(20); 


  


   // Creating a view 


   var dataview1 = new DataView(buffer, 0, 10); 


  


   // putting no data at slot 1 


   dataview1.setUint32(1); 


   document.write(dataview1.getUint32(1) + "<br>");
