我正在尝试从嵌套在对象中的详细信息数组下面的_id“ bennyRawMaterial”删除所有对象:
let recipeBasicRecipes = [{
_id:'12345',
name:'Macaron Shell',
details:[
{
name: 'Sugar',
_id: 'bennyRawMaterial',
type: 'solid',
}
,
{
name: 'Egg white',
_id: '5fef680ca43301322a3224e5',
type: 'solid'
}]
},
{
_id:'14512345',
name:'Macaron Shell',
details:[{
name: 'Castiors gar',
_id: 'bennyRawMaterial',
type: 'solid'
},
{
name: 'oil',
_id: 'bennyRawMaterial',
type: 'solid',
}
, {
name: 'food',
_id: 'bennyRawMaterial',
type: 'solid',
}]
}]
我正在使用以下代码删除对象,但是跳过了一些对象。请帮助实现
recipeBasicRecipes.forEach(br => {
br.details.forEach((rm, index) => {
if (rm._id === 'bennyRawMaterial') {
br.details.splice(index, 1);
} else {
return true;
}
});
let recipeBasicRecipes = [{
_id: '12345',
name: 'Macaron Shell',
details: [{
name: 'Sugar',
_id: 'bennyRawMaterial',
type: 'solid',
},
{
name: 'Egg white',
_id: '5fef680ca43301322a3224e5',
type: 'solid'
}
]
},
{
_id: '14512345',
name: 'Macaron Shell',
details: [{
name: 'Castiors gar',
_id: 'bennyRawMaterial',
type: 'solid'
},
{
name: 'oil',
_id: 'bennyRawMaterial',
type: 'solid',
}, {
name: 'food',
_id: 'bennyRawMaterial',
type: 'solid',
}
]
}
]
var uniqueIds = []; //global ids array
recipeBasicRecipes.forEach(el => {
let details = [];//unique details array
el.details.forEach((dt, i) => {
let id = dt._id;
if (!uniqueIds.includes(id)){ //check id exists in global ids array
uniqueIds.push(id);
details.push(dt); //copy unique details
}
});
el.details = details; //update details with unique details
});
console.log(recipeBasicRecipes)
