javascript - 比较两个不同的数组元素删除node js中的匹配元素

Question

我有两个数组对象，如下所示:

var arrayOne = [{"Name":"job","SubscriptionGUID":"8ead7edfa460"},{"Name":"TestJobSQL","SubscriptionGUID":"09e7dbff7779"}];
var arrayTwo = [{"UserSubscriptionID":13,"SubscriptionGUID":"8ead7edfa460","Name":"job"}];
var arrayDiff = [];

我需要比较元素Name并删除匹配的元素，仅在arrayDiff中显示不匹配的数组元素

根据上面的示例，我的新 arrayDiff 应该是

var arrayDiff = [{"Name":"TestJobSQL"}]; or var arrayDiff = ['TestJobSQL'];

如果arrayTwo是

var arrayTwo = [];

然后arrayDiff应该返回

var arrayDiff = [{"Name":"TestJobSQL"},{"Name":"Job"}]; or  var arrayDiff = ['TestJobSQL', 'Job'];

试试这个

var arrayOne = [{"Name":"job","SubscriptionGUID":"8ead7edfa460"},{"Name":"TestJobSQL","SubscriptionGUID":"09e7dbff7779"}];
var arrayTwo = [{"UserSubscriptionID":13,"SubscriptionGUID":"8ead7edfa460","Name":"job"}];
var arrayDiff = [];
arrayOne.forEach(function(item, index){
    var found = false;
    arrayTwo.forEach(function(item1, index1){
        if(item.Name == item1.Name) {
            found = true;
        }   
    })
    if(found == false) {
        arrayDiff.push({ Name : item.Name});
    }
})
console.log(arrayDiff);
