javascript - 将 JavaScript 对象添加到另一个对象的末尾时出现问题

Question

我有一个函数，它从先前的 JSON 响应接收数据，调用另一个 Web 服务，并将第二次调用的结果添加到原始 JSON 响应的末尾。但是，当我使用扩展时，原始数组中的项目会被新数组中的项目替换。我知道使用 $.extend 会使用相同的键覆盖我的项目，但我找不到另一个选项，因为我没有尝试 $.merge 我需要的项目将它们连接起来。还有其他可行的选择吗？谢谢!

//data is the object to which I am trying to add data
function verificaFileServer(data, subprograma, etapa, destino, lista, listaFileServer){

    //checking whether some variable has been passed into the function
    if(listaFileServer !== undefined){

        //SharePoint REST Endpoint
        var urlREST = "/_api/lists/getbytitle('File Server')/items?" + 
                      "$select=Title,Link,Modified&$orderby=Modified desc&$filter=IDdoEvento eq " + subprograma + " and EtapaPAS eq '" + etapa + "' and TipodeArquivo eq '" + listaFileServer + "'";

        $.ajax({
            url: urlREST,
            headers: { "Accept": "application/json; odata=verbose"},
            success:function(dadosFileServer) {

                //trying to add to the end of my original JSON object
                $.extend(data.d.results,dadosFileServer.d.results);

                //creating a new array containing the original and the new data
                dadosConcatenados = data.d.results.sort(function(a, b) {
                    return (b["Modified"] > a["Modified"]) ? 1 : ((b["Modified"] < a["Modified"]) ? -1 : 0);
                });

                //calling a function that will build the output based on the concatenated array
                montaSaida(dadosConcatenados, subprograma, etapa, lista, destino);

            }
        });

    } else {
        //calling a function that will build the output based on the original data
        montaSaida(data, subprograma, etapa, lista, destino);
    }

}

Answer 1

However, the items on the original array get replaced by items in the new array.

尝试使用Array.prototype.concat()

var data = [1, 2, 3];

data = data.concat(4, 5, 6, 7, {"abc": [8, 9]});

console.log(data)
