json 多维数组到 javascript 中的树结构

Question

我有这个 JSON 响应：

    [
{storeWebsites=[
    {website_id=1.0, name=Default Store View}, 
    {website_id=0.0, name=Admin}
    ]}, 
{storeGroups=[
   {website_id=0.0, name=Default, id=0.0}, 
    {website_id=1.0, name=Main Website Store, id=1.0}
    ]}, 
{storeViews=[
    {website_id=1.0, name=Default Store View, code=default, id=1.0}, 
    {website_id=0.0, name=Admin, code=admin, id=0.0}
    ]}
]

我想将“website_id”和 append 归为“storeViews.name”。

我正在尝试使用下面的脚本，但我无法推送 var 组中的值：

     var groups = {};

// .... code to push the values in var groups
 
  $.each(groups, function(key, groups) {
    var $group1 = $("<optgroup>").attr("label", "  " + groups.storeWebsites);
    var $group2 = $("<optgroup>").attr("label", "    " + groups.storeGroups);
  
    groups.storeViews.forEach(function(el) {
      $group2.append(new Option(el.name, el.code));
    });
  
    $('#provider-accounts').append($group1, $group2);
  
  }); 
 
} 

所以我的“id=provider-accounts”应该填充如下：

<optgroup label="Default Store View"></optgroup>
<optgroup label="Main Website Store">
    <option code="default">Default Store View</option>
</optgroup>

    <optgroup label="Admin"></optgroup>
<optgroup label="Default">
    <option code="admin">Admin</option>
</optgroup>

有什么帮助吗？

我认为您交换了以下组：

• <optgroup label="Default">
• <optgroup label="Main Website Store">

无论如何，您可以解构您的站点、组和视图，并在循环其中一个时跟踪它们的索引。

 const main = () => { const [ { storeWebsites }, { storeGroups }, { storeViews }] = json; $('#provider-accounts').append(storeWebsites.flatMap((site, index) => { const group = storeGroups[index], view = storeViews[index]; return [ $('<optgroup>', { label: site.name }), $('<optgroup>', { label: group.name }).append($('<option>', { code: view.code, text: view.name })) ]; })); }; const json = [{ "storeWebsites": [{ "website_id": 1.0, "name": "Default Store View" }, { "website_id": 0.0, "name": "Admin" }] }, { "storeGroups": [{ "website_id": 0.0, "name": "Default", "id": 0.0 }, { "website_id": 1.0, "name": "Main Website Store", "id": 1.0 }] }, { "storeViews": [{ "website_id": 1.0, "name": "Default Store View", "code": "default", "id": 1.0 }, { "website_id": 0.0, "name": "Admin", "code": "admin", "id": 0.0 }] }]; main();
