如何使用javascript创建单个对象并在数组中列出它们

How to create individual objects and list them in an array using javascript?

本文关键字：数组 javascript 何使用 创建 单个 对象      更新时间：2023-09-26

我当前的数组没有按照我的意愿创建单个对象。我的数据格式如下：

["1434100866", "599.0", "1434100870", "349.0", "1434100863", "233.0", "1434100849", "269.0", "1434100857", "682.0", "1434100862", "248.0", "1434100865", "342.0", "1434100848", "960.0", "1434100853", "270.0", "1434100850", "253.0"]

我希望我的数据采用以下格式：

[[item1, item2],[item1, item2],[item1, item2], ...];

这是我的代码：

        var dataArray = new Array();
        @foreach (var record in Model)
        {
            @:dataArray.push("@record.date", "@record.rate");
        }        
        console.log(dataArray);

您想要push一个新数组，而不是新值。这样做：

var dataArray = new Array();
@foreach (var record in Model)
{
    @:dataArray.push(["@record.date", "@record.rate"]);
}        
console.log(dataArray);


var a=["1434100866", "599.0", "1434100870", "349.0", "1434100863", "233.0", "1434100849", "269.0", "1434100857", "682.0", "1434100862", "248.0", "1434100865", "342.0", "1434100848", "960.0", "1434100853", "270.0", "1434100850", "253.0"];
var b = a.reduce(function (res, el, i) {
    if (i % 2) {
        res[res.length - 1].push(el);
    } else {
        res.push([el]);
    }
    return res;
}, []);
 document.getElementById('out').innerHTML = JSON.stringify(b, null, 4);
<pre id="out"></pre>
