问题描述

如何从javascript中的数组中获取最多的重复值?

How can I get the most repeated value from an Array in javascript?

这是我的数组

var data = [
    { values: "Number of pips" }, 
    { values: 4 }, 
    { values: 4 }, 
    { values: 4 }, 
    { values: 5 }, 
    { values: 2 }, 
    { values: 6 }, 
    { values: 6 },
    { values: 5 }
];

结果应该是4，我怎么能得到这个?

The result should be 4, how can I get this?

我已经尝试过此操作，取自获取数组中出现次数最多的元素

I have tried this, taken from Get the element with the highest occurrence in an array

function mode(array)
{
    if(array.length == 0)
        return null;
    var modeMap = {};
    var maxEl = array[0], maxCount = 1;
    for(var i = 0; i < array.length; i++)
    {
        var el = array[i];
        if(modeMap[el] == null)
            modeMap[el] = 1;
        else
            modeMap[el]++;    
        if(modeMap[el] > maxCount)
        {
            maxEl = el;
            maxCount = modeMap[el];
        }
    }
    return maxEl;
}

但这是返回6, not 4.

推荐答案

我明白了

var arr= [{ values: "Number of pips" }, { values: 4 }, { values: 4 }, { values: 4 }, { values: 5 }, { values: 2 }, { values: 6 }, { values: 6 }, { values: 5 }];



    var uniqs = {};

    for(var i = 0; i < arr.length; i++) {
        uniqs[arr[i].values] = (uniqs[arr[i].values] || 0) + 1;
    }

    var max = { val: arr[0], count: 1 };
    for(var u in uniqs) {
        if(max.count < uniqs[u]) { max = { val: u, count: uniqs[u] }; }
    }

    alert(max.val);
