HTML Alert

Normally it is not possible to use HTML tags in an alert. But if you add the following function to your script

function HtmlAlert( text, clr1, title, clr2, bclr )
{
    //background-layout
    htmlAlertLayout = app.CreateLayout( "linear", "VCenter,FillXY" );
    htmlAlertLayout.Animate( "FadeIn", "", 100 );
    htmlAlertLayout.SetBackColor( [bclr.slice(0, 1), "33", bclr.slice(1)].join('') );
 
    //alert-layout
    htmlAlert = app.CreateLayout( "linear", "Left" );
    htmlAlert.SetBackColor( bclr );
    htmlAlert.SetSize( 0.8, 0.2 );
 
    //title-text
    htmlAlertTitle = app.CreateText( title );
    htmlAlertTitle.SetTextSize( 30 );
    htmlAlertTitle.SetMargins( 0.02 );
    htmlAlertTitle.SetTextColor( clr2 );
 
    //horizontal line below
    htmlAlertHr = app.CreateText( "", 1, 0.002 );
    htmlAlertHr.SetBackColor( clr2 );
 
    //text in alert
    htmlAlertText = app.CreateText( "", 0.8, 100, "Multiline,Left");
    htmlAlertText.SetMargins( 0.02 );
    htmlAlertText.SetHtml( text );
    htmlAlertText.SetTextColor( clr1 );
 
    //horizontal line below
    htmlAlertHr2 = app.CreateText( "", 0.8, 0.002 );
    htmlAlertHr2.SetBackColor( clr2 );
 
    //"Ok" button
    htmlAlertButton = app.CreateText( "Ok", 0.8, 0.055 );
    htmlAlertButton.SetPadding( 0, 0.01 );
    htmlAlertButton.SetBackColor( bclr );
    htmlAlertButton.SetTextColor( clr1 );
    htmlAlertButton.SetOnTouchUp( function() { htmlAlertLayout.Animate( "FadeOut", "", 100 ); app.RemoveLayout( htmlAlertLayout ); } );
 
    //add objects to app
    htmlAlert.AddChild( htmlAlertTitle );
    htmlAlert.AddChild( htmlAlertHr );
    htmlAlert.AddChild( htmlAlertText );
    htmlAlertLayout.AddChild( htmlAlert );
    htmlAlertLayout.AddChild( htmlAlertHr2 );
    htmlAlertLayout.AddChild( htmlAlertButton );
    app.AddLayout( htmlAlertLayout);
}

and call the method for example like that

//Called when application is started.
function OnStart()
{
    app.EnableBackKey( false );
    lay = app.CreateLayout( "linear" );
    lay.SetSize( 1, 1 );
    lay.SetBackColor( "#fff56f" );
    app.AddLayout( lay );
}
 
function OnBack()
{
    HtmlAlert( "<s>text</s><br><b>text</b><br><u>text</u>", "#fff56f", "title", "#fff56f", "#121212" );    
}

Then you are able to use HTML tags in an alert.
