new SimIFrameClient(frame)
This SimIFrameClient communicates to one and only one iframe. Dispose it when you are done with it. There is not
any support for having two SimIFrameClients connect to the same sim iframe. Available in the main PhET-iO js import.
Parameters:
| Name | Type | Description |
|---|---|---|
frame |
Object | an HTML element representing the iframe with the simulation. |
Methods
dispose()
Release resources when the SimIFrameClient instance will no longer be used.
invoke(phetioID, method, argsopt, callbackopt)
Primary way to call a method on the simulation frame from the wrapper frame. Given an instance id, method name, and
arguments, invoke the method async and return values then errors (in that order) in the callback.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
phetioID |
InvocationData.phetioID | The id of the instance | |
method |
InvocationData.method | The name of the phet-io method | |
args |
InvocationData.args |
<optional> |
optional args |
callback |
function |
<optional> |
optional callback, parameters depend on method being invoked. |
invokeSequence(sequence, callbackopt)
If you need to send multiple messages or if the order of messages matters, then use invokeSequence.
callback is called when the entire sequence is complete.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
sequence |
Array.<InvocationData> | Each "Invocation" entry in the array will be run async. | |
callback |
function |
<optional> |
The arguments will depend on the return values of the methods invoked. The args will be all return values followed by all errors. i.e. if there are five invocations in a sequence call, each returning a single value, then there will be ten arguments in the callback. Further more if all are successful but the last, which returns an error, then there are still ten args, but (one indexed) args 5-9 will be null, and the tenth will hold an Error. |
launchSim(URL, optionsopt)
Main launch point for the simulation, send a message into the simulation to begin. Some options can be very helpful
in customizing the simulation run before the launch command has been sent to the sim, see LaunchSimOptions object
for more.
Parameters:
| Name | Type | Attributes | Description |
|---|---|---|---|
URL |
string | the URL of the simulation to launch | |
options |
LaunchSimOptions |
<optional> |
optional parameters to pass to the launch sequence |
