Now you can open the PowerShell ISE editor and add the following code.

  1. # Add Snapin  
  2. if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)   
  3. {  
  4.     Add-PSSnapin "Microsoft.SharePoint.PowerShell"  
  5. }  
  7. # Update Page  
  8. $web = Get-SPWeb http://sharepoint  
  9. $page = "/Lists/My%20Tasks/AllItems.aspx"  
  10. $file = $web.GetFile($page)  
  12. $file.CheckOut();  
  14. $manager = $web.GetLimitedWebPartManager($page, [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)  
  15. $webpart = $manager.WebParts[0]  
  16. $webpart.JSLink = "/siteassets/helloworld.js"  
  17. $manager.SaveChanges($webpart);  
  19. $file.CheckIn("JS Link updated");  
Change the Server URL appropriately and run the code. If the code is executed successfully, you will get your page updated.


You can verify the page update by opening the page in edit mode. Go to the web part properties and you can see that the JavaScript link was updated there.

JS link

This concludes the JavaScript Link updating using PowerShell.

Note: Please note that the preferred way of update is using CSOM code. In this way we can use the same code base for both SharePoint On-Premise and Online.
