SharePoint 2013 Hosting – HostForLIFE.eu :: How to Update JS Link of Site in SharePoint with Powershell?

In this tutorial, I will show you how to Update JS Link of Site in SharePoint 2013 with Powershell. First Open your SharePoint site and create a list from the Tasks template shown on the below picture:

Name it My Tasks

And then, you’ll get the tasks list as shown on the below picture:

Now, copy the URL of the list. We will need it in the next step.
Note: Please note that we require %20 also to denote the space character.

After that, copy HelloWorld.js. Create a HelloWorld.js file and copy it to the Site Assets library.

Now, open the PowerShell ISE editor and write the following code:

# Add Snapin  
if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)   
{  
    Add-PSSnapin "Microsoft.SharePoint.PowerShell"  
}  
# Update Page  
$web = Get-SPWeb http://sharepoint  
$page = "/Lists/My%20Tasks/AllItems.aspx"  
$file = $web.GetFile($page)  
$file.CheckOut();  
$manager = $web.GetLimitedWebPartManager($page, [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)  
$webpart = $manager.WebParts[0]  
$webpart.JSLink = "/siteassets/helloworld.js"  
$manager.SaveChanges($webpart);  
$file.CheckIn("JS Link updated");

# Add Snapin

if ((Get-PSSnapin "Microsoft.SharePoint.PowerShell" -ErrorAction SilentlyContinue) -eq $null)

{

Add-PSSnapin "Microsoft.SharePoint.PowerShell"

}

# Update Page

$web = Get-SPWeb http://sharepoint

$page = "/Lists/My%20Tasks/AllItems.aspx"

$file = $web.GetFile($page)

$file.CheckOut();

$manager = $web.GetLimitedWebPartManager($page, [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)

$webpart = $manager.WebParts[0]

$webpart.JSLink = "/siteassets/helloworld.js"

$manager.SaveChanges($webpart);

$file.CheckIn("JS Link updated");

Change the Server URL appropriately and run the code. If the code is executed with success, you’ll 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’ll see that the JavaScript link was updated there.

This concludes the JavaScript Link updating using PowerShell.

Please note that the popular way of update is using CSOM code. in this way we can use a similar code base for each SharePoint On-Premise and on-line.
