我在SharePoint Online中的SharePoint加载项中有一个“列”列,这是一个多行富文本字段。我想使用Power-Shell将其转换为Enhance Rich Text字段。

$ URL,$ Username,$ password和$ ListTitle作为参数传递给编写此代码的函数。

try
{
    $ctx=New-Object Microsoft.SharePoint.Client.ClientContext($Url)
    $ctx.Credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($Username, $password)
    $ctx.Load($ctx.Web)
    $ctx.ExecuteQuery()
    $ll=$ctx.Web.Lists.GetByTitle($ListTitle)
    $ctx.Load($ll)
    $ctx.ExecuteQuery()
    #Add new field to the list
    Write-Host "`nGot List" $ListTitle

    $fieldColl = $ll.Fields;

    $isDescriptionPlainText = $false;
    $ctx.Load($fieldColl);
    $ctx.ExecuteQuery();
    foreach ($item in $fieldColl) 
    {
        if($item.InternalName -eq "VisualDescription")
        {

            if($item.InternalName -eq "VisualDescription" -and $item.RichText -eq $false)
            {
                Write-Host ("`n'{0}' Field available.Making Rich Text"-f $item.InternalName)
                $msg=("`n'{0}' Field available.Making Rich Text"-f $item.InternalName)
                writeToLog $msg
                $isDescriptionPlainText=$true;
                $item.RichText = $true
                $item.update()
            }
            else
            {
                Write-Host ("`n Field not available or already a rich text.")
                $msg=("Field not available or already a rich text.")
                writeToLog $msg
            }
        }           
    }
    if($isDescriptionPlainText)
    {
        $ll.update()
        $ctx.Load($ll)
        $ctx.ExecuteQuery()
    }
}
catch
{
    $errorMessage = $_.Exception.Message
    $errLineNumber = $_.InvocationInfo.ScriptLineNumber
    $errOffset = $_.InvocationInfo.OffsetInLine
    $msg = "The script failed due to an unexpected error. [Reason]: $errorMessage [Error Line Number]: $errLineNumber ($errOffset)"
    writeErrorToLog $msg
    # Log the entire stack trace
    writeErrorToLog $_.Exception
    Write-Error $msg
}

我无法使用$item.RichTextMode = "FullHtml"因为RichTextMode属性不存在$item

经过几天的努力,我终于能够解决使用PowerShell将SharePoint加载项列表的多行字段更新为增强型RichText的问题。

我们需要在字段的SchemaXML属性中进行更改,并将RichTextModeCompatible替换为FullHtml

$item.SchemaXml=$item.SchemaXml.Replace("RichTextMode=`"Compatible`"","RichTextMode=`"FullHtml`"")
