Adding Custom Action to SharePoint Online site

In this post, I'm providing the SPO powershell script which you can run from SPO management shell to add a new custom action to specific site.


You can use this script to render scripts on specific pages inside a site and  there by add any new options to users/ hide any option from end users.


Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.dll"
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Runtime.dll"
Add-Type -Path "c:\Program Files\Common Files\microsoft shared\Web Server Extensions\16\ISAPI\Microsoft.SharePoint.Client.Publishing.dll"
# Authenticate with the SharePoint site.
#
$actionName = "EM_SPO_JOSPODELWEB_JS_Injection"
$actionType = "ScriptLink"
$actionSourceFile ="https://yourtenant.sharepoint.com/sites/JoSPO/SiteAssets/HideSiteDeletion.js"
$siteUrl = Read-Host -Prompt "Enter web url:"
$username = Read-Host -Prompt "Enter Username:"
$password = Read-Host -Prompt "Enter password" -AsSecureString
$ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteUrl)
# SharePoint Online
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $password)
$ctx.Credentials = $credentials
$rootWeb = $ctx.Web
$ctx.Load($rootWeb)
$actions = $rootWeb.get_userCustomActions()
$ctx.Load($actions)
$ctx.ExecuteQuery()
if($actions)
{
$actionsToDelete = @()
foreach($action in $actions)
{
if($action.get_description() -eq $actionName -and $action.get_location() -eq $actionType) {
Write-Host "Action found:" $action.get_description() -foregroundcolor white -backgroundcolor Green
$actionsToDelete += $action
}
}
foreach($actionToDelete in $actionsToDelete) {
    $actionToDelete.deleteObject()
Write-Host "Action deleted" -foregroundcolor white -backgroundcolor Green
}
$ctx.ExecuteQuery()
}
Write-Host "Installing action"  -foregroundcolor white -backgroundcolor Green
$newAction = $actions.add();
$newAction.set_description($actionName);
$newAction.set_location('ScriptLink');
$scriptBlock = 'var headIDDetails = document.getElementsByTagName("head")[0];var newScriptDetails = document.createElement("script");newScriptDetails.type = "text/javascript";newScriptDetails.src="';
$scriptBlock += $actionSourceFile + '?ver=' + (Get-Date) ;
$scriptBlock += '";headIDDetails.appendChild(newScriptDetails);';
$newAction.set_scriptBlock($scriptBlock);
$newAction.update();
$ctx.ExecuteQuery();
Write-Host "Action" $newAction.Description "installed" -foregroundcolor white -backgroundcolor Green

  1. Hello. I see you talking about dll files, and have ever encountered with problem a loss of one of the files dll. Most often, the error msvcp140 dll pops up, when you try to start the game, also the system knocks out the error msvcp140 dll in runing some programs. The solution in all cases is almost identical, you just need to msvcp140.dll download https://fix4dll.com/msvcp140_dll you may do it here, and install the msvcp140 dll file, and the problem is eliminated with games and programs. The problem itself is not difficult. And it often appears, those who do not know how to deal with this, that's my advice to them.
