将重复的JSON名称转换为对象？

问题描述

我有以下字符串...

{
    "Qualifications[0].DegreeType": "Degree Type 1",
    "Qualifications[0].Classification": "Clasification 1",
    "Qualifications[0].CourseTitle": "Course Title 1",
    "Qualifications[0].YearOfAward": "2018",
    "Qualifications[0].AwardingInstitution": "Awarding institution 1",
    "Qualifications[1].DegreeType": "Degree Type 2",
    "Qualifications[1].Classification": "Classification 2",
    "Qualifications[1].CourseTitle": "Course Title 2",
    "Qualifications[1].YearOfAward": "2019",
    "Qualifications[1].AwardingInstitution": "Awarding Institution 2",
    ... and so on...
 }

有谁知道将其转换为javascript对象的简单方法，这样我就可以有效地...

$(Qualifications).each(i, v){
    //do stuff on whatever property of Qualifications[i]
}

我能想到的唯一方法是使用字符串操作以及类似下面的内容，但是它需要针对每个属性进行大量自定义代码检查映射，而我正在寻找更通用，更简单的方法。

    let i = 0;
    while (Qualifications[" + i +"].whateverProperty..) {
        //add to object array
        i++;
    }

您可以像这样简单地使用标准的Object.keys ：

 let qualifications = []
 const my_object = {
    "Qualifications[0].DegreeType": "Degree Type 1",
    "Qualifications[0].Classification": "Clasification 1",
    "Qualifications[0].CourseTitle": "Course Title 1",
    ...
 }


Object.keys(my_object).forEach(key => {
    //to access the index you could then do:
    const idx = Number(key.split('[')[1].split(']')[0])
    const sub_key = key.split('.')[1]
    //not here that i don't verify if the index exists
    if (!qualifications[idx]) qualifications[idx] = {}
    qualifications[idx][sub_key] = my_object[key]
})
