The New-UDElement cmdlet allows you to create custom React elements within your dashboard. Similar to New-UDHtml, you can define HTML elements using New-UDElement. Unlike, New-UDHtml, you can update elements, set auto refresh and take advantage of the React component system.

Create an Element

You need to specify the -Tag and -Content when creating an element. The below example creates a div tag.

New-UDElement -Tag 'div' -Content { 'Hello' }

You can nest components within each other to create HTML structures. For example, you could create an unordered list with the following example.

New-UDElement -Tag 'ul' -Content {
    New-UDElement -Tag 'li' -Content { 'First' }
    New-UDElement -Tag 'li' -Content { 'Second' }
    New-UDElement -Tag 'li' -Content { 'Third' }
}

Setting Attributes

You can select attributes of an element (like HTML attributes) by using the -Attributes parameter. This parameter accepts a hashtable of attribute name and values. The below example creates red text.

New-UDElement -Tag 'div' -Content { 'Hello' } -Attributes @{
    style = @{
        color = 'red'
    }
}

Auto Refreshing Elements

You can define the -AutoRefresh, -RefreshInterval and -Endpoint parameters to create an element the refreshes on a certain interval. The below example creates an element that refreshes every second and displays the current time.

New-UDElement -Tag 'div' -Endpoint {
    Get-Date
} -AutoRefresh -RefreshInterval 1

Setting Element Properties Dynamically

You can use the Set-UDElement cmdlet to set element properties and content dynamically. The following example sets the content of the element to the current time.

New-UDElement -Tag 'div' -Id 'myElement' -Content { }
​
New-UDButton -Text 'Click Me' -OnClick {
    Set-UDElement -Id 'myElement' -Content { Get-Date }
}

You can also set attributes by using the -Properties parameter of Set-UDElement. The following example sets the current time and changes the color to red.

    New-UDElement -Tag 'div' -Id 'myElement' -Content { }
​
    New-UDButton -Text 'Click Me' -OnClick {
        Set-UDElement -Id 'myElement' -Content { Get-Date } -Properties @{ Attributes = @{ style = @{ color = "red" } } }
    }

Adding Child Elements

You can add child elements using Add-UDElement. The following example adds child list items to an unordered list.

New-UDElement -Tag 'ul' -Content {
​
} -Id 'myList'
​
New-UDButton -Text 'Click Me' -OnClick {
    Add-UDElement -ParentId 'myList' -Content {
        New-UDElement -Tag 'li' -Content { Get-Date }
    }
}

Clearing Child Elements

You can clear the child elements of an element by using Clear-UDElement. The following example clears all the list items from an unordered list.

New-UDElement -Tag 'ul' -Content {
    New-UDElement -Tag 'li' -Content { 'First' }
    New-UDElement -Tag 'li' -Content { 'Second' }
    New-UDElement -Tag 'li' -Content { 'Third' }
}  -Id 'myList'
​
New-UDButton -Text 'Click Me' -OnClick {
    Clear-UDElement -Id 'myList'
}

Forcing an Element to Reload

You can force an element to reload using Sync-UDElement. The following example causes the div to reload with the current date.

New-UDElement -Tag 'div' -Endpoint {
    Get-Date
} -Id 'myDiv'
​
New-UDButton -Text 'Click Me' -OnClick {
    Sync-UDElement -Id 'myDiv'
}

Removing an Element

You can remove an element by using Remove-UDElement.

New-UDElement -Tag 'div' -Endpoint {
    Get-Date
} -Id 'myDiv'
​
New-UDButton -Text 'Click Me' -OnClick {
    Remove-UDElement -Id 'myDiv'
}
