我一直试图从JavaScript对象中删除嵌套对象,但没有成功,也无法通过搜索以前的帖子来找到正确的答案。
这就是我一直想做的。
<code id='code'></code>
var myobj = {
"children": [
{
"name": "albuterol ",
"children": [
{
"name": "albuterol - fluticasone ",
"children": [
{
"name": "prednisone ",
"children": [
{
"name": "dexamethasone ",
"children": [],
"size": 1,
"colname": "CONCEPT_NAME.4"
}
],
"size": 3,
"colname": "CONCEPT_NAME.3"
}
],
"size": 4,
"colname": "CONCEPT_NAME.2"
}]}]}
function deleteObject(myobj) {
var x = delete myobj.colname
return (myobj.name, myobj.children)
}
document.getElementById('code').innerText = JSON.stringify(deleteObject(myobj))
我要删除对象colname
。我是否缺少某些内容或代码完全不正确?

您需要一个递归函数才能删除该属性。
var myobj = {
"children": [
{
"name": "albuterol ",
"children": [
{
"name": "albuterol - fluticasone ",
"children": [
{
"name": "prednisone ",
"children": [
{
"name": "dexamethasone ",
"children": [],
"size": 1,
"colname": "CONCEPT_NAME.4"
}
],
"size": 3,
"colname": "CONCEPT_NAME.3"
}
],
"size": 4,
"colname": "CONCEPT_NAME.2"
}]}]}
function deleteColnameRecursive(obj){
delete obj.colname
if(obj.children){
for(var i=0;i<obj.children.length;i++)
deleteColnameRecursive(obj.children[i]);
}
}
deleteColnameRecursive(myobj);
console.log(myobj);

MyObj没有直接的colname属性。 MyObj有一个名为Children的数组。
要删除适当的属性,请选择适当的对象。例如myObj.children[0].colname
