我正在尝试迭代JSON(玩家和建筑物)的索引,以便我可以在jQuery
中获得新的结果我有两个索引JSON一个有玩家的信息,第二个索引有建筑相关玩家的信息。
我想解析它,这样我就可以得到玩家和它的建筑名称。
My Actual JSON result
{
"Players": [
{
"id": "35",
"building_id": "8",
"room_num": "101",
},
{
"id": "36",
"building_id": "9",
"room_num": "102",
},
{
"id": "37",
"building_id": "10",
"room_num": "103",
},
{
"id": "38",
"building_id": "11",
"room_num": "104",
}
],
"Buildings": [
{
"id": "8",
"name": "ABC"
},
{
"id": "9",
"name": "DEF"
},
{
"id": "10",
"name": "GHI"
},
{
"id": "11",
"name": "JKL"
}
]
}
需要这个
"information": [
{
"player_id": "35",
"Buildings_name": "ABC"
},
{
"player_id": "36",
"Buildings_name": "DEF"
},
{
"player_id": "37",
"Buildings_name": "GHI"
},
{
"player_id": "38",
"Buildings_name": "JKL"
}
]
}
给你,这是每个玩家,检查是否有建筑,并将它们映射到新的结构。这将不会过滤没有映射到玩家的建筑的值,也不会包括没有玩家的建筑。
var x = {
"Players": [
{
"id": "35",
"building_id": "8",
"room_num": "101",
},
{
"id": "36",
"building_id": "9",
"room_num": "102",
},
{
"id": "37",
"building_id": "10",
"room_num": "103",
},
{
"id": "38",
"building_id": "11",
"room_num": "104",
}
],
"Buildings": [
{
"id": "8",
"name": "ABC"
},
{
"id": "9",
"name": "DEF"
},
{
"id": "10",
"name": "GHI"
},
{
"id": "11",
"name": "JKL"
}
]
};
var res = $.map(x.Players, function(item) {
return {
player_id: item.id,
building_name: $.grep(x.Buildings, function(i) {
return i.id == item.building_id
}).length != 0 ? $.grep(x.Buildings, function(i) {
return i.id == item.building_id
})[0].name : undefined
}
})
,如果你想过滤没有关系的值,例如INNER join
var resInnerJoin = $.grep($.map(x.Players, function(item) {
return {
player_id: item.id,
building_name: $.grep(x.Buildings, function(i) {
return i.id == item.building_id
}).length != 0 ? $.grep(x.Buildings, function(i) {
return i.id == item.building_id
})[0].name : undefined
}
}), function(it) {
return it.building_name != undefined
})
如果在PHP中需要:
$json = '{...}';
// create and PHP array with you json data.
$array = json_decode($json, true);
// make an array with buildings informations and with building id as key
$buildings = array();
foreach( $array['Buildings'] as $b ) $buildings[$b['id']] = $b;
$informations = array();
for ( $i = 0 ; $i < count($array['Players']) ; $i++ )
{
$informations[$i] = array(
'player_id' => $array['Players'][$i]['id'],
'Buildings_name' => $buildings[$array['Players'][$i]['building_id']]['name']
);
}
$informations = json_encode($informations);
var_dump($informations);
