[英]Looping through an object and adding values to a Javascript object with the incremental count as the key
例子:
{
Do you have a monthly student payment?: 133,
Do you have a monthly car loan payment?: 150,
Do you have a monthly car insurance payment?: 120,
How much do you estimate you spend on gas for your car monthly?: 150
}
Output: {120: 1, 133: 1, 150: 1}
預期 output:
{1: 133, 2: 150, 3: 120 , 4: 150}
我的 function:
getClicked() {
this.newObj = {};
this.mortgageRateFound = [];
for (let key in this.numbersInForm) {
console.log(this.numbersInForm)
if (! this.newObj[this.numbersInForm]) {
this.newObj[this.numbersInForm[key]] = (this.newObj[key]+1) || 1
}
}
console.log(this.newObj);
}
您可以使用Object.values
來獲取 object 中每個鍵的值,然后Array.map
使用數組索引 (+1) 作為對象數組然后,您可以使用Object.assign
將該對象數組展平為單個 object:
const obj = { "Do you have a monthly student payment?": 133, "Do you have a monthly car loan payment?": 150, "Do you have a monthly car insurance payment?": 120, "How much do you estimate you spend on gas for your car monthly?": 150 }; const out = Object.assign({}, ...Object.values(obj).map((v, i) => ({ [i+1]: v }))); console.log(out);
const obj = { "Do you have a monthly student payment?": 133, "Do you have a monthly car loan payment?": 150, "Do you have a monthly car insurance payment?": 120, "How much do you estimate you spend on gas for your car monthly?": 150 }; var output = Object.keys(obj).reduce(function(acc, curr, index) { acc[index] = obj[curr] return acc; }, {}) console.log(output)
