javascript - 如何使用 jQuery 将值插入到特定索引处的二维数组中

Question

我有以下 2 个数组:

groupedObjects: [
    { value: 125, currency: "EUR" }, 
    { value: 100, currency: "USD" }, 
    {value: 320, currency: "RON" }
]
groupedObjects1: [
    { value: 500, currency: "EUR" }, 
    { value: 280, currency: "RON" }
]

如何让这两个数组看起来相同？我想要第二个数组，代码如下:

[
    { value: 500, currency: "EUR" }, 
    { value: 0, currency: "USD" }, 
    { value: 280, currency: "RON" }   
]

我尝试过这段代码:

if ($(groupedObjects).length > $(groupedObjects1).length) {
    _.each(groupedObjects,function(obj){
        i++;
        _.each(groupedObjects1,function(obj1){
            if(obj.currency != obj1.currency) {
                alert('Test');
                groupedObjects1.push ({
                    value: '',
                    currency: ''
                });
            }                               
        });
    });
} 

我希望两个数组都按货币排序，并且它们都应该具有相同数量的元素，无论哪个数组更大

    groupedObjects= [
        { value: 125, currency: "EUR" }, 
        { value: 100, currency: "USD" }, 
        {value: 320, currency: "RON" }
    ];
    groupedObjects1= [
        { value: 500, currency: "EUR" }, 
        { value: 280, currency: "RON" }
    ];


if ($(groupedObjects).length > $(groupedObjects1).length) {

var newArray = [];
$.each(groupedObjects, function (key, value) {
    var flag = false;
    var breakout = false;
    flag = (function () {
        $.each(groupedObjects1, function (key1, value1) {
            if (value.currency === value1.currency) {
                newArray.push(value1);
                breakout = true;
                return false;
            }

        });
        if (!breakout) {
            return true;
        }
    })();
    if (flag) {
        newArray.push({
            value: 0,
            currency: value.currency
        });
    }
});
groupedObjects1 = newArray;

}
