AS3 字符串转转数组，数组转字符串，splice

从一个字符串中去掉相连的重复字符，原字符串“adffjkljaalkjhl”变为“adfjkljalkjhl”

 

var str:String = "adffjkljaaaaalkkkkjhhhfffl";var arr:Array = str.split("");for(var i=0;i<arr.length-1;i++){if(arr[i]==arr[i+1]){arr.splice(i+1,1);i-=1;}}str="";for(var i=0;i<arr.length;i++){str+=arr[i];}trace(str);
