我想找到一种方法来找到一个数组中最常见的值,所以在下面的数组中称为"数据"它有10个值" 1"。我如何能够提取这些信息,发现很难找到任何相关信息。任何帮助,将不胜感激!
var data:Array = ["1","1","1","1","1","1","1","1","1","2","2","one","two","five","six","1","2","one","two","three","four","five","2","one","two","three","four","five","2","five","2","one","two","five","six","2","one","two","five","six","2","one","two","five","six"];
results = "1";
答案 0 :(得分:3)
这可能不是最有效的方式,但它确实可以解决问题:
function mostCommonValue(array:Array):Object
{
// create a dictionary of each unique item in the array and its count
var dict:Dictionary = new Dictionary(true);
for each(var element:Object in array)
{
if(!dict[element]){
dict[element] = 0;
}
dict[element]++;
}
var max:Number = 0;
var mostCommon:Object;
// loop over each item in the dictionary to find the highest number of occurrences
for(var key:Object in dict)
{
if(dict[key] > max){
max = dict[key];
mostCommon = key;
}
}
return mostCommon;
}
