javascript - 修改 JSON 数组标签

Question

有谁知道如何修改 JSON 数组中的标签？

可以说我的数组是：

[{"Device_ID":"43","Image":"Amazon-Kindle-Fire.png","Manufacturer":"Amazon","Model":"Kindle Fire","Type":"Tablet"},{"Device_ID":"43","Image":"Apple-iPad.png","Manufacturer":"Apple","Model":"iPad","Type":"Tablet"}]

如何操作它，以便 Device_ID 成为标签，制造商和型号的组合成为值？

这是 jquery 自动完成所必需的，我无法在源代码中修改当前 JSON 数组

更新：

目前尝试这种方式没有成功：

$(function() {
    var availableTags = <?php echo json_encode($results); ?>;
    var john = availableTags.forEach(function(v){v.Device_ID = v.Manufacturer + v.Model});
    $("#search_input").autocomplete({
        source: john;
    }); 
});

Answer 1

试试看：

o = [{"Device_ID":"43","Image":"Amazon-Kindle-Fire.png","Manufacturer":"Amazon","Model":"Kindle Fire","Type":"Tablet"},{"Device_ID":"43","Image":"Apple iPad.png","Manufacturer":"Apple","Model":"iPad","Type":"Tablet"}]
o.forEach(function(v){v.Device_ID = v.Manufacturer + " " + v.Model})

它将循环遍历数组中的每个对象，并将 id 分配给您需要的组合。
