以特定方式订购对象

Question

我正在尝试按name对以下对象进行排序。我希望列表按以下方式排序1(balloon2(term3(instalment。

loanAdjustmentList = [
{
"description": "Restructure Option",
"name": "instalment",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
},
{
"description": "Restructure Option",
"name": "term",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
},
{
"description": "Restructure Option",
"name": "balloon",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
}
]

知道我能试试什么吗？

Answer 1

您希望对数组进行排序。

您只需要编写一个将另一个对象用作映射的排序函数。

const order = ["balloon", "installment", "term"]

loanAdjustmentList.sort((el1, el2) => { 
if (order.indexOf(el1.name) < order.indexOf(el2.name) {
return -1;
} else (order.indexOf(el1.name) > order.indexOf(el2.name) {
return 1;
} else {
return 0;
}
});

当然，这是假设它们只是有问题的三个选项之一。如果您有任何其他名称类型，它可能会引发错误。

我已经包含了name元素可能相同的可能性，这将允许对3个以上的选项进行排序。

Answer 2

如果您的意思是按照提到的三个名称排序，您可以尝试以下操作：

let loanAdjustmentList = [
{
"description": "Restructure Option",
"name": "instalment",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
},
{
"description": "Restructure Option",
"name": "term",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
},
{
"description": "Restructure Option",
"name": "balloon",
"restructureAllowed": "N",
"reason": "Due to the status of your account we are unable to process your request. Please contact 0860 669 669 for more information",
"reasonCode": "1"
}
]
loanAdjustmentList = [
...loanAdjustmentList.filter(x => x.name === 'balloon'),
...loanAdjustmentList.filter(x => x.name === 'term'),
...loanAdjustmentList.filter(x => x.name === 'instalment')
];
console.log(loanAdjustmentList);
