我正在使用我的第一個Adobe Flex應用程序,並且有一段代碼部分顯示爲運行速度非常慢(但它的功能正常!)。如何提高此Adobe Flex腳本的速度?

CC_Output是文本控件,所有其他控件的複選框(CC,CC_Duration等)

任何幫助將不勝感激!

<mx:Script>     


     private function updateLabel():void { 
      var HPI_Score:Number = 0; 
      if (CC.selected) {CC_Output.text = "CC/HPI - Brief";} 

      if (!CC.selected) { 
       CC_Output.text = "CC/HPI - Inadequate"; 
      } else { 

       if (CC_Duration.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Location.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Quality.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Severity.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Timing.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Context.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Modify.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Assoc.selected) {HPI_Score=HPI_Score+1;} 
       if (CC_Chronic_Dx.selected) {HPI_Score=HPI_Score+4;} 

       if (HPI_Score > 3) {CC_Output.text = "CC/HPI - Extended";} 
      } 
     } 

</mx:Script> 
<mx:TextArea id="LBL" x="262" y="28" enabled="true" visible="true" width="142"/> 
<mx:CheckBox x="10" y="71" label="Duration" id="CC_Duration" enabled="true" visible="true" click="updateLabel();"/>

對我來說運行速度很快 – Amarghosh 2009-11-27 06:00:56

在真空中,該代碼在筆記本電腦上運行良好(如果我添加了CC控件)。

我將它重寫了一下以便快速退出,並且在某些情況下可能會有所改進。

 private function updateLabel():void 
    { 
     const messageInadequate:String = "CC/HPI - Inadequate"; 
     const messageBrief:String = "CC/HPI - Brief"; 
     const messageExtended:String = "CC/HPI - Extended"; 

     if (!CC.selected) 
     { 
      CC_Output.text = messageInadequate; 
      return; 
     } 

     if (CC_Chronic_Dx.selected) 
     { 
      CC_Output.text = messageExtended; 
      return; 
     } 

     var HPI_Score:int = 0; 

     if (CC_Duration.selected) HPI_Score++; 
     if (CC_Location.selected) HPI_Score++; 
     if (CC_Quality.selected) HPI_Score++; 
     if (CC_Severity.selected) HPI_Score++; 
     if (CC_Timing.selected) HPI_Score++; 
     if (CC_Context.selected) HPI_Score++; 
     if (CC_Modify.selected) HPI_Score++; 
     if (CC_Assoc.selected) HPI_Score++; 

     if (4 > HPI_Score) 
     { 
      CC_Output.text = messageBrief; 
     } 
     else 
     { 
      CC_Output.text = messageExtended; 
     } 
    }

建立你想做的事,並導入組件到主應用程序和使用什麼樣一個組成部分。那麼文件大小會降低,性能會增加。

它奇怪,它運行緩慢。代碼中沒有什麼特別的事情發生

是的,代碼不乾淨,但這並不影響性能。

嘗試運行Flex Profiler並查找可能的瓶頸(如果存在)。
