JavaScript dataView.getUint32() Method
Below is the example of the dataView.setUint32() Method.
- Example:
<script>varbuffer =newArrayBuffer(20);vardataview1 =newDataView(buffer, 0, 10);dataview1.getUint32(1, 12);document.write(dataview1.getUint32(1));</script>chevron_rightfilter_none - Output:
12
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 were to read the data.
Return value: It returns an unsigned 32-bit integer.
Example 1:
Input: dataview1.getUint32(1, 56); Output: 56
Example 2:
Input: dataview1.getUint32(1, Math.PI); Output: 3
JavaScript code to show the working of this method:
Code #1:
<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> |

filter_none
Output:
56
Code #2:
This function convert the float value of PI form 3.14 to 3
<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.setUint32(1, Math.PI); document.write(dataview1.getUint32(1) + "<br>"); </script> |
chevron_right
filter_none
Output:
3
Code #3:
When there is no data to be stored, then it returns zero (0).
<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.setUint32(1); document.write(dataview1.getUint32(1) + "<br>"); </script> |

Output:
