as3按日期/時間順序目錄

Question

我需要你幫忙找到一個解決方案來按創建日期時間排列數組。 我嘗試這個，但這個功能似乎只按日期排序，而不是按時間排在一起。

private function triImgDate(folder:Array):void { 
     var acDirectory:ArrayCollection = new ArrayCollection(); 

     for each (var tmp:File in folder) { 
      if (!tmp.isDirectory) { 
       if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase())) 
       { 

        listeImages.addItem(tmp); 

       } 
      } 
      else { 
       triImgDate(tmp.getDirectoryListing()); 
      } 
     } 

     var dataSortField:SortField = new SortField(); 
     dataSortField.name = "creationDate"; 
     dataSortField.numeric = false; 
     var numericDataSort:Sort = new Sort(); 
     numericDataSort.fields = [dataSortField]; 
     listeImages.sort = numericDataSort; 
     listeImages.refresh(); 



    } 

所以，如果你能幫助我。

//解決方案

private function triImgDate(folder:Array):void { 


     var acDirectory:ArrayCollection = new ArrayCollection(); 
     var arTempListeImages:ArrayCollection = new ArrayCollection(); 
     var arTempListeCompar:ArrayCollection = new ArrayCollection(); 


     var objImg:Object; 
     for each (var tmp:File in folder) { 
      if (!tmp.isDirectory) { 
       if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase())) { 

        objImg= new Object(); 
        //listeImages.addItem(tmp); 
        arTempListeImages.addItem(tmp); 
        objImg.creationDate=tmp.creationDate; 
        objImg.url=tmp.url; 
        objImg.pos=arTempListeCompar.length; 
        arTempListeCompar.addItem(objImg) 


       } 
      } else { 
       triImgDate(tmp.getDirectoryListing()); 
      } 
     } 

     var dataSortField:SortField = new SortField(); 
     dataSortField.name = "creationDate"; 
     dataSortField.compareFunction = function (a:Object, b:Object) : int { 
      var na:Number = a.creationDate.getTime(); 
      var nb:Number = b.creationDate.getTime(); 

      if (na < nb) 
       return -1; 

      if (na > nb) 
       return 1; 

      return 0; 
     }; 

     var numericDataSort:Sort = new Sort(); 
     numericDataSort.fields = [dataSortField]; 

     arTempListeCompar.sort= numericDataSort; 
     arTempListeCompar.refresh(); 
     var cpt:int=0; 
     for each (var objTem:Object in arTempListeCompar) { 

      listeImages.addItem(arTempListeImages[arTempListeCompar[cpt].pos]); 
      cpt++; 
     } 

     arTempListeImages=[]; 
     arTempListeCompar=[]; 
     acDirectory=[]; 

    }

你想在這裏做什麼，是比較TWE通過他們的字符串表示，這顯然是不這樣做的好辦法日期。

你應該使用compareFunction屬性的SortField對象。類似的東西（未測試）：

private function triImgDate(folder:Array):void { 
    var acDirectory:ArrayCollection = new ArrayCollection(); 
    for each (var tmp:File in folder) { 
    if (!tmp.isDirectory) { 
     if (tmp.extension != null && ArrayFunction.inArray(tabExt, tmp.extension.toLowerCase())) { 
     listeImages.addItem(tmp); 
     } 
    } else { 
     triImgDate(tmp.getDirectoryListing()); 
    } 
    } 

    var dataSortField:SortField = new SortField(); 
    dataSortField.name = "creationDate"; 
    dataSortField.sortFunction = function(date1:Date, date2:Date):int { 
    const t1:uint = date1.time; 
    const t2:uint = date2.time; 
    if (t1 < t2) { 
     return -1; 
    } 

    if (t1 == t2) { 
     return 0; 
    } 

    return 1; 
    } 

    var numericDataSort:Sort = new Sort(); 
    numericDataSort.fields = [dataSortField]; 
    listeImages.sort = numericDataSort; 
    listeImages.refresh(); 
}
