javascript - 将数组从 php 转换为 javascript

Question

我有来自数据库的数组，带有 json_encode，如下所示:

"[{"uid":"595e7d","name":"Elephant"},{"uid":"701b03","name":"Bird"},{"uid":"29a8c","name":"Lion"}]"

但是当我像这样在 JavaScript 中显示时，如何使数组只显示记录而不显示字段/列名称:

JavaScript 数组:

{ 
    "595e7d": "Elephant",
    "701b03": "Bird",
    "29a8c": "Lion" 
}

应该用 php 还是 javascript 来完成？

谢谢

Answer 1

使用 JavaScript 处理:

function transfrom (arrs){
  return arrs.reduce((init, arr) => {
      init[arr.uid] = arr.name
      return init
  }
 , {})
}

//usage

let arrs = [{"uid":"595e7d","name":"Elephant"},{"uid":"701b03","name":"Bird"},{"uid":"29a8c","name":"Lion"}]
transfrom(arrs)

// {595e7d: "Elephant", 701b03: "Bird", 29a8c: "Lion"}

或者你可以用 PHP 处理它:

<?php
$arr = array (
  array('uid' =>"595e7d", "name"=>"Elephant"), 
  array("uid" =>"701b03", "name" =>"Bird"), 
  array("uid" =>"29a8c", "name" =>"Lion")
); 

function transform($v1, $v2) {
    $v1[$v2["uid"]] = $v2["name"];
    return $v1;    
} 

echo json_encode(array_reduce($arr, "transform", array())); 
// { 
//     "595e7d": "Elephant",
//     "701b03": "Bird",
//     "29a8c": "Lion" 
// }
?>
