我有以下陣列格式：
[
{
"category": "c8kr0cv012vtr8vm3iqg",
"subcategories": [
"c8kr3d7012vtr8vm3jm0",
"c8kr3d7012vtr8vm3jlg",
"c8kr3d7012vtr8vm3jk0",
"c8kr8h7012vtr8vm3m5g",
"c8tjghovq0ahq4ccf980",
"c8kr3nn012vtr8vm3jog",
"c8kr3nn012vtr8vm3jo0",
"c8kr3nn012vtr8vm3jp0",
]
},
{
"category": "c8kr0cv012vtr8vm3ivg",
"subcategories": [
"c8kr3d7012vtr8vm3jm0",
"c8kr3d7012vtr8vm3jlg",
"c8kr3d7012vtr8vm3jk0",
"c8kr8h7012vtr8vm3m5g",
"c8tjghovq0ahq4ccf980",
"c8kr3nn012vtr8vm3jog",
"c8kr3nn012vtr8vm3jo0",
"c8kr3nn012vtr8vm3jp0",
]
},
{
"category": "c8kr0cv012vtr8vm3is0",
"subcategories": [
"c8kr3d7012vtr8vm3jm0",
"c8kr3d7012vtr8vm3jlg",
"c8kr3d7012vtr8vm3jk0",
"c8kr8h7012vtr8vm3m5g",
"c8kr3nn012vtr8vm3jog",
"c8kr3nn012vtr8vm3jo0",
"c8kr3nn012vtr8vm3jp0",
]
},
{
"category": "c8kr0cv012vtr8vm3ir0",
"subcategories": [
"c8kr3d7012vtr8vm3jm0",
"c8kr3d7012vtr8vm3jlg",
"c8kr3d7012vtr8vm3jk0",
"c8kr8h7012vtr8vm3m5g",
"c8tjghovq0ahq4ccf980",
"c8kr3nn012vtr8vm3jog",
"c8kr3nn012vtr8vm3jo0",
"c8kr3nn012vtr8vm3jp0",
]
}
]
例如，我想從subcategory陣列中洗掉值c8tjghovq0ahq4ccf980
我嘗試了以下代碼：
tempPayload.some(function (a) {
return a.subcategories.some(function (b, i, bb) {
if (b === "c8tjghovq0ahq4ccf980") {
bb.splice(i, 1);
return true;
}
});
});
但它不知道如何解決這個問題？
uj5u.com熱心網友回復：
嘗試使用以下代碼：
tempPayload.map((item) => {
const index = item.subcategories.indexOf("c8tjghovq0ahq4ccf980");
if (index > -1) {
item.subcategories.splice(index, 1);
}
});
uj5u.com熱心網友回復：
for(let i=0; i<tempPayload.length; i ){
tempPayload[i].subcategories = tempPayload[i].subcategories.filter(i => i!== "c8tjghovq0ahq4ccf980")
}
console.log(tempPayload)
