在属性中组合两个字符串对象以在 .map 循环中使用

Question

我将 PHP 对象组合成字符串，这给了我这个结果：{"icon":"dark-mode","classes":"dark-mode","local":"test1"}{"icon":"settings","classes":"settings","local":"test2"}如何将此字符串转换为数组，以便可以使用 .map 函数对其进行映射？

Answer 1

好吧，您的示例描述了两个 JavaScript 对象，因此不确定您到底要什么。

这些方法之一？

var line1 = {

  "icon": "dark-mode",

  "classes": "dark-mode",

  "local": "test1"

};

var line2 = {

  "icon": "settings",

  "classes": "settings",

  "local": "test2"

};

var combined = {};

Object.keys(line1).forEach(function(key) {

  if (combined[key]) {

    combined[key].push(line1[key]);

  } else {

    combined[key] = [line1[key]]

  }

});

Object.keys(line2).forEach(function(key) {

  if (combined[key]) {

    combined[key].push(line2[key]);

  } else {

    combined[key] = [line2[key]]

  }

});

console.log(combined);

console.log([line1, line2]);

Answer 2

使用Object.keys(youObj) 转换对象的键并将其用于映射

const someObj = {"icon":"dark-mode","classes":"dark-mode","local":"test1"}

const objToString = Object.keys(someObj).map(item => `key = ${item}, item = ${someObj[item]}`)

console.log(objToString)
