Javascript 如何查询具有特定id的json文件并获得结果数组？

我正在努力研究如何根据循环中的当前id获取temp.json的值。请参阅下面的代码。我希望能够根据temp.json中匹配的传递id（deliveryid和temp_deliveryid）检索数组。然后将它们打印到表中。temp.json的内容将不断变化

deliveries.json

网站代码示例

$.getJSON("jsonfiles/deliveries.json", function(delivery) {
    for(var i = 0; i < delivery.all_info.length; i++) {  
       var deliv = delivery.all_info[i];
           x = '<div id="' + deliv.deliveryid + '">' + deliv.deldescription + '</div>
           document.getElementById("sortable1").innerHTML += x;
                $.getJSON("jsonfiles/temp.json", function(temp) {
                    deliv.forEach(function(entry) {
                       var tempi = tempe.temp_info[i];
                         if (tempi.temp_deliveryid == entry.deliveryid){
var y = '<tr><td>[' + temp.temp_recorded_time + '] '+ temp.temperature_id + ' - Temperature: ' + temp.recorded_temp +'&#x2103; - Weather (' + temp.weather + ')!</td></tr>';    
document.getElementById("temptbody").innerHTML += y;    
     });
    }
  });
}); 

$.getJSON（“jsonfiles/deliveries.json”），函数（delivery）{
对于（var i=0；i

如我在评论中所述，如果deliveries.json没有temp.json那么频繁地更改，我会这样做

$.getJSON("jsonfiles/deliveries.json", function(delivery) { var x =''; for(var i = 0; i < delivery.all_info.length; i++) { var deliv = delivery.all_info[i]; x += '<div id="' + deliv.deliveryid + '">' + deliv.deldescription + '</div>'; } $("#sortable").html(x); }); $.getJSON（“jsonfiles/deliveries.json”），函数（delivery）{ var x=“”； 对于（var i=0；i 然后获取你的temp.json

$.getJSON("jsonfiles/temp.json", function(temp) { var temps = {}; var y=''; for(var i = 0; i < temp.temp_info.length; i++) { var tempi = tempe.temp_info[i]; y += '<tr><td>[' + temp.temp_recorded_time + '] '+ temp.temperature_id + ' - Temperature: ' + temp.recorded_temp +'℃ - Weather (' + temp.weather + ')!</td></tr>'; } $("#temptbody").html(y); }); $.getJSON（“jsonfiles/temp.json”，函数（temp）{ var temps={}； 变量y=“”； 对于（var i=0；i#sortable和

#testbody

之间的关系。

如果存在这种关系，另一种选择可能是将deliveries.json保存为变量，然后在检索temp.json时，将适当的temp详细信息直接附加到deliveries.json。json

如果temp.json的内容不断变化，deliveries.json的内容是否不定期变化？如果是，为什么nest temp的getJson insine deliveries？看看这个问题，希望这能告诉你怎么做，谢谢你的回答，但这仍然没有解释如何比较每个交付的temp.temp_deliveryid和deliver.deliveryid。
