To measure the width of a div element we will utilize the offsetWidth property of JavaScript. This property of JavaScript returns an integer representing the layout width of an element and is measured in pixels.
Syntax:
element.offsetWidth
- Return Value:
- Returns the corresponding element’s layout pixel width.
Example:
The following program will illustrate the solution using offsetWidth:
Program 1:
<!DOCTYPE html> <html> <head> <title> neveropen </title> <style> #GFG { height: 30px; width: 300px; padding: 10px; margin: 15px; background-color: green; } </style> </head> <body> <div id="GFG"> <b>Division</b> </div> <button type="button" onclick="Geeks()"> Check </button> <script> function Geeks() { var elemWidth = document.getElementById("GFG").offsetWidth; alert(elemWidth); } </script> </body> </html> |
Output:
320
The another method to measure the width of a div element we will utilize the clientWidth() property of JavaScript.
The following program will illustrate the solution using clientWidth:
Program 2:
<!DOCTYPE html> <html> <head> <title> neveropen </title> <style> #GFG { height: 30px; width: 300px; padding: 10px; margin: 15px; background-color: green; } </style> </head> <body> <div id="GFG"> <b>Division</b> </div> <button type="button" onclick="Geeks()"> Check </button> <script> function Geeks() { var elemWidth = document.getElementById("GFG").clientWidth; alert(elemWidth); } </script> </body> </html> |
Output:
320
Note: clientWidth returns the inner width which includes padding but excludes borders and scroll bars whereas offsetWidth returns the outer width which includes padding and borders.
