javascript - 如何在 JavaScript 的数组中存储值？

Question

我的 JavaScript 代码是:

<script type="text/javascript">
    var photo = {"cover1":"arsenal.jpg", "cover2":"liverpool.jpg"};
    var photoList = [
        {"id":1, "name":"chelsea.jpg"},
        {"id":2, "name":"mu.jpg"},
        {"id":3, "name":"arsenal.jpg"},
        {"id":4, "name":"city.jpg"},
        {"id":5, "name":"liverpool.jpg"}
    ];
    for (var i = 0; i < photoList.length; i++) { 
        if(photoList[i].name == photo.cover1 || photoList[i].name == photo.cover2) {
            console.log(photoList[i].id)
        }
    }
    // I want to store it in array like this = [3,5]
</script>

console.log(photoList[i].id)的结果是3和5。

我想将它存储在一个数组中，如下所示:[3,5]。因此，如果满足 if 条件，则该值将存储在数组中

我该怎么做？

您可以创建一个数组并将其插入其中。就像

<script type="text/javascript">
    var photo = {"cover1":"arsenal.jpg", "cover2":"liverpool.jpg"};
    var photoList = [
        {"id":1, "name":"chelsea.jpg"},
        {"id":2, "name":"mu.jpg"},
        {"id":3, "name":"arsenal.jpg"},
        {"id":4, "name":"city.jpg"},
        {"id":5, "name":"liverpool.jpg"}
    ];
    var result = []
    for (var i = 0; i < photoList.length; i++) { 
        if(photoList[i].name == photo.cover1 || photoList[i].name == photo.cover2) {
            result.push(photoList[i].id);
        }
    }
    // I want to store it in array like this = [3,5]
</script>
