AnimateCC Canvas调用函数

Question

我尝试将我从AmazonS3Exception: The AWS Access Key Id you provided does not exist in our records.] Amazon.Runtime.Internal.HttpErrorResponseExceptionHandler.HandleException(IExecutionContext executionContext, HttpErrorResponseException exception) +580 Amazon.Runtime.Internal.ExceptionHandler1.Handle(IExecutionContext executionContext, Exception exception) +76 Amazon.Runtime.Internal.ErrorHandler.ProcessException(IExecutionContext executionContext, Exception exception) +197 Amazon.Runtime.Internal.ErrorHandler.InvokeSync(IExecutionContext executionContext) +73 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.CallbackHandler.InvokeSync(IExecutionContext executionContext) +27 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.Signer.InvokeSync(IExecutionContext executionContext) +25 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.CredentialsRetriever.InvokeSync(IExecutionContext executionContext) +29 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.RetryHandler.InvokeSync(IExecutionContext executionContext) +132 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.CallbackHandler.InvokeSync(IExecutionContext executionContext) +27 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.S3.Internal.AmazonS3KmsHandler.InvokeSync(IExecutionContext executionContext) +29 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.EndpointResolver.InvokeSync(IExecutionContext executionContext) +27 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.S3.Internal.AmazonS3PostMarshallHandler.InvokeSync(IExecutionContext executionContext) +29 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.Marshaller.InvokeSync(IExecutionContext executionContext) +25 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.S3.Internal.AmazonS3PreMarshallHandler.InvokeSync(IExecutionContext executionContext) +29 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.CallbackHandler.InvokeSync(IExecutionContext executionContext) +27 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.S3.Internal.AmazonS3ExceptionHandler.InvokeSync(IExecutionContext executionContext) +58 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.ErrorCallbackHandler.InvokeSync(IExecutionContext executionContext) +56 Amazon.Runtime.Internal.PipelineHandler.InvokeSync(IExecutionContext executionContext) +16 Amazon.Runtime.Internal.MetricsHandler.InvokeSync(IExecutionContext executionContext) +119 Amazon.Runtime.Internal.RuntimePipeline.InvokeSync(IExecutionContext executionContext) +26 Amazon.Runtime.AmazonServiceClient.Invoke(TRequest request, IMarshaller`2 marshaller, ResponseUnmarshaller unmarshaller) +190 Amazon.S3.AmazonS3Client.ListObjects(ListObjectsRequest request) +44 DownloadFile.GetFoldersOnly(String folder) in c:\Users\Hamzastein\Documents\Visual Studio 2013\WebSites\PhotoGallery\DownloadFile.aspx.cs:110 DownloadFile.Page_Load(Object sender, EventArgs e) in c:\Users\Hamzastein\Documents\Visual Studio 2013\WebSites\PhotoGallery\DownloadFile.aspx.cs:17 System.Web.Util.CalliEventHandlerDelegateProxy.Callback(Object sender, EventArgs e) +51 System.Web.UI.Control.OnLoad(EventArgs e) +95 System.Web.UI.Control.LoadRecursive() +59 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +678 更改为actionscript 3的代码。我对调用我创建的函数有疑问，例如：

html5 canvas

我想让以下功能调用function cleanSelection(){ this.a1.visible = true; this.sa1.visible = false; this.a2.visible = true; this.sa2.visible = false; } function maxSelection(count){ cleanSelection(); count = 0; return count; } 来调用maxSelection()

cleanSelection()

如何调用这些功能？

Answer 1

你应该把＆＃34;绑定（这个）＆＃34;在所有方法中：

function cleanSelection(){
   this.a1.visible = true;
   this.sa1.visible = false;

   this.a2.visible = true;
   this.sa2.visible = false;
}

function maxSelection(c){
   cleanSelection.bind(this)();
   c= 0;
   return c;
}
var count = 0;
this.a1.addEventListener("click", fl_Click.bind(this));
function fl_Click() {
  this.sa1.visible = true;
  this.a1.visible = false;
  count++;
  if(count >= 2){
     count = maxSelection.bind(this)(count);
  }

}
