Actionscript：从数组中选择并显示重复的值

请问如何从数组中获取重复的值

例： 数组[10,3,10,10]
显示位置1、3和4中有3个重复项

问候

我试过这个：

 q = new Array();
                q = [A, B, C, D];

                qValue = function (array) {
                equal = array[0];
                for (j=0; j<array.length; j++) {
                if (array[j]===equal) {
                equal = array[j];
                }
                }
                return equal;
                };
                trace(qValue(q));

q=新数组（）；
q=[A，B，C，D]；
qValue=函数（数组）{
相等=数组[0]；
对于（j=0；j类似的东西应该可以：

var array:Array = [1,2,3,4,3];

// create a dictionary and go through our array pulling out the keys
var dict:Dictionary = new Dictionary();
for each( var i:int in array )
{
    if( i in dict ) // checks if the number is already in our dict as a key
        dict[i]++;
    else
        dict[i] = 1;
}

// now go through our dictionary, finding the duplications
for( var key:* in dict )
{
    var num:int = dict[key];
    if( num == 1 )
        continue; // single value - ignore
    trace( "We have " + num + " occurrences of " + key );
}

编辑

要获得重复值的位置（标记），请改为使用：

var array:Array = [1,2,3,4,3];

// create a dictionary and go through our array, pulling out the values
var dict:Dictionary = new Dictionary();
var len:int         = array.length;
for( var i:int = 0; i < len; i++ )
{
    var val:int = array[i]; // get the value from the array
    if( !( val in dict ) )  // if it's not in our dictionary, create a new array
        dict[val] = [];
    dict[val].push( i );    // add the index of the value to the array
}

// now go through our dictionary, finding the duplications
for( var key:* in dict )
{
    var indicies:Array = dict[key];
    if( indicies.length <= 1 )
        continue; // single value - ignore
    trace( "The value " + key + " is repeated " + indicies.length + " times. Indicies: " + indicies );
}

您的数组循环现在应该为

for( var i:int = 0; i < len; i++ )
{
    var val:int = array[i]; // get the value from the array
    var occurrenceArray = _getArray( obj, val ); // obj = dict
    occurrenceArray.push( i ); //  add the index of the value to the array
}

for（变量i:int=0；i
您尝试了什么吗？是的，请看第一篇博文谢谢，仍然是重复的位置的prb insee更新-我们只是用包含指示的数组替换计数它与as2不兼容：（将
字典
替换为
对象
，它应该仍然很好。如果（！（val in dict））

中的键，则新编辑基本上都是

，如果找到它，则返回true-您可以使用自己的函数来执行相同的操作
for( var i:int = 0; i < len; i++ )
{
    var val:int = array[i]; // get the value from the array
    var occurrenceArray = _getArray( obj, val ); // obj = dict
    occurrenceArray.push( i ); //  add the index of the value to the array
}
