我正在嘗試創(chuàng)建一個 javascript 對象作為引導(dǎo)樹視圖的輸入。我有 php 從 mysql 獲取數(shù)據(jù)，并將結(jié)果編碼為以下結(jié)構(gòu)：{"Company 1":{"Production":["Brands","Categories","Products","Stocks"],"Sales":["Customers","Orders","Staffs","Stores"]},"Company 2":{"Production":["Brands","Categories","Products","Stocks"],"Sales":["Customers","Orders","Staffs","Stores"]}}生成該 json 的 PHP 代碼：$databases=[];foreach($result as $row){$database=$row["database"];$schema=$row["schema"];$table=$row["object"];if(!array_key_exists($database, $databases)) $databases[$database]=[];if(!array_key_exists($schema, $databases[$database])) $databases[$database][$schema]=[];array_push($databases[$database][$schema], $table);}echo json_encode($databases);但我正在努力將該 json 結(jié)構(gòu)放入所需的 JavaScript 對象的嵌套數(shù)組中。以下是所需的結(jié)構(gòu)：[ { text: "Company 1", nodes: [ { text: "Production", nodes: [ { text: "Brands" }, { text: "Categories" }, { text: "Products" }, { text: "Stocks" } ] }, { text: "Sales", nodes: [ { text: "Customers" }, { text: "Orders" }, { text: "Staffs" }, { text: "Stores" } ] } ] }, { text: "Company 2", nodes: [ { text: "Production", nodes: [ { text: "Brands" }, { text: "Categories" }, { text: "Products" }, { text: "Stocks" } ] }, { text: "Sales", nodes: [ { text: "Customers" }, { text: "Orders" }, { text: "Staffs" }, { text: "Stores" } ] } ] } ];任何建議，將不勝感激

我建議使用遞歸flatItem函數(shù)來做到這一點。我還介紹了一個array_map_with_keys輔助函數(shù)，因為 PHP 自己的array_map函數(shù)會忽略鍵，而在您的情況下，我們需要它。
function array_map_with_keys($callback, $array){
return array_map($callback, array_keys($array), $array);
}
function flatItem($key, $value) {
if(is_array($value)){
return
["text" => $key,
"nodes" => array_map_with_keys("flatItem", $value)
];
}else{
return ["text" => $value];
}
}
$converted = array_map_with_keys("flatItem", $databases);
echo json_encode($converted);
結(jié)果就是你所期望的：
[{"text":"Company 1","nodes":[{"text":"Production","nodes":[{"te
xt":"Brands"},{"text":"Categories"},{"text":"Products"},{"text":
"Stocks"}]},{"text":"Sales","nodes":[{"text":"Customers"},{"text
":"Orders"},{"text":"Staffs"},{"text":"Stores"}]}]},{"text":"Com
pany 2","nodes":[{"text":"Production","nodes":[{"text":"Brands"}
,{"text":"Categories"},{"text":"Products"},{"text":"Stocks"}]},{
"text":"Sales","nodes":[{"text":"Customers"},{"text":"Orders"},{
"text":"Staffs"},{"text":"Stores"}]}]}]
你可以把它傳遞給js。

const data = {
"Company 1": {
"Production": ["Brands", "Categories", "Products", "Stocks"],
"Sales": ["Customers", "Orders", "Staffs", "Stores"]
},
"Company 2": {
"Production": ["Brands", "Categories", "Products", "Stocks"],
"Sales": ["Customers", "Orders", "Staffs", "Stores"]
}
}
function converter(data) {
return Object.entries(data).reduce((converted, [key, val]) => {
const element = {
text: key,
nodes: [...Object.entries(val).map(([key2, val2]) => {
return {
text: key2,
nodes: [...Object.values(val2).map(val3 => {
return {
text: val3
}
})]
}
})]
}
converted.push(element);
return converted
}, []);
}
console.log(converter(data))
