# Backdrop

Tilføj indlæsningsoverlejringer til PowerShell Universal-apps med New-UDBackdrop, der viser brugerdefineret indhold og lukker backdropen med en OnClick-handler.

Backdrop-komponenten placerer en overlejring over hele siden. Den er nyttig til at vise indlæsningstilstande.

## Grundlæggende backdrop

Hvis De vil oprette en grundlæggende backdrop, kan De bruge cmdletten `New-UDBackdrop` og medtage indhold, der skal vises i backdropen. Indholdet centreres på siden. Brug switch-parameteren `-Open` for at vise backdropen.

```powershell
New-UDBackdrop -Content {
    New-UDTypography -Text "Loading..." -Variant h2
} -Open
```

## OnClick-hændelseshandler

Backdropet har en `-OnClick`-handler, som De kan bruge til at lukke backdropet, når der klikkes. De kan bruge `Set-UDElement` til at åbne og lukke backdropet.

```powershell
New-UDBackdrop -Id 'backdrop' -Content {
    New-UDTypography -Text "Loading..." -Variant h2
} -Open -OnClick {
    Set-UDElement -Id 'backdrop' -Properties @{
        open = $false
    }
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/powershell-universal/da/apps/components/feedback/backdrop.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
