ActionScript and properties

Flash Lite 1.1 supports most Flash 4 ActionScript commands. The following are notable 
exceptions:

•

Use the 

add

 operator instead of the 

&

 command to concatenate strings.

•

Button mouse events such as 

dragOver

, 

dragOut

, and 

releaseOutside

 cannot be used to 

trigger ActionScript code attached to buttons. However, in addition to keypress events, you 
can use the 

press

, 

release

, 

rollOver

, and 

rollOut

 events to trigger ActionScript when 

attached to buttons and accessed through key-based navigation.

•

Draggable movie clip functions and properties (for example: 

startDrag

, 

stopDrag

, and 

_dropTarget

 properties) are not supported.

•

Use the 

eq

 operator to compare strings and the 

==

 operator for numeric comparison.

•

URL encoding must be done manually using ActionScript. The 

escape()

 ActionScript 

function is not a Flash 4 function and is not available in Flash Lite 1.1. 

•

Two new FSCommand2 commands have been added to encode a string into a format that is 
safe for network transfer: 

Escape

 and 

Unescape

. For more information, see 

.

•

The default Quality level for Flash Lite during playback is medium, and there is no support for 
bitmap smoothing.

•

Flash Lite 1.1 supports 

loadMovie()

, 

loadMovieNum()

, 

loadVariables()

, and 

loadVariablesNum()

. Only one LoadMovie and LoadVars action is processed per frame or 

per event handler. Certain handsets restrict these actions to keyEvents only, in which case the 
action call is processed only if it is triggered in a keyEvent handler. Even under such 
circumstances, only one such action is processed per event handler. For more information, see 

.

•

Only one 

getURL()

 action is processed per frame or per event handler. Certain handsets 

restrict the 

getURL()

 action to keyEvents only, in which case the 

getURL()

 call is processed 

only if it is triggered in a keyEvent handler. Even under such circumstances, only one 

getURL()

 action is processed per event handler. 

An example of using the 

tel

 protocol would be the following:

on (release, keyPress "#"){

getURL(“tel:117”);

}
