Question

for (var i = 1; i < address.length; i++) {
    var markers = [{"name":"marker"+i, "address":address[0]}];
}

循环后我希望我的json标记看起来像

name: marker1, address: aaaa
name: marker2, address: abcd
name: marker3, address: adf

帮我修复我的代码。在此先感谢，我是json的新手，我不知道如何用空值初始化它并在for循环中插入值。

Answer 1

好的，所以这很容易。

var markers = [];

// This still needs address to be an array, also still don't understand why you don't begin at the start of the array
for (var i = 1; i < address.length; i++) {
    markers.push({
        name: "marker" + i,
        address: address[i]
    });
}

// If you do want to start at the begininning of the array, but still want it to start with "markers1"
for (var i = 0; i < address.length; i++) {
    markers.push({
        name: "marker" + (i + 1),
        address: address[i]
    });
}

假设地址已经是一个有效的javascript数组，这将为您提供一个如下所示的数组：

[
    { name: "marker1", address: "whatever was here" },
    { name: "marker2", address: "whatever was there" }
]

    var address = ['aaaa', 'abcd', 'adf'];
    var markers = [];
      for (var i = 0; i < address.length; i++) {
        markers.push({
            name: "marker" + (+i + 1),
            address: address[i]
        });
    }
    var jsonMarkers = JSON.stringify(markers);
    // And jsonMarkers will look like :

    //"[{"name":"marker1","address":"aaaa"},{"name":"marker2","address":"abcd"},{"name":"marker3","address":"adf"}]"

JSON使用javascript在循环中插入值
