javascript - 根据javascript中的id删除对象内部数组中的对象

Question

正如标题所说，我正在尝试根据 id 删除对象内数组内的对象。请在下面查看我的对象:

{"satisfied":[],
"support":
[
    {"id":187,"question":"supot1"}
],
"agree":
[
    {"id":891,"question":"asdff"},
    {"id":394,"question":"Dos"},
    {"id":495,"question":"Tres"}
],
"yesno":[],
"multichoice":
[
    {"id":785,"question":"multi1",
    "choices":["item1","item2", "item3"]},
    {"id":986,"question":"multi2",
    "choices":["item4", "item5", "item6"]}
],
"oneofmany":[]
}

例如，我想删除 {"id":891,"question":"asdff"}，我该怎么做？

要遍历所有这些子数组，您可以遍历对象的值:

 for(const array of Object.values(input)) {

然后在该数组中，搜索匹配的对象并在必要时将其拼接出来:

  const toFind = 891;
  const index = array.findIndex(it => it.id === toFind);
  if(index !== -1) 
    array.splice(index, 1);
 }
