求助：将字符串数组转换为JavaScript对象的方法

Got it, let's work through this problem! Your input strings are semi-structured key-value lists separated by commas, but they aren't valid JSON—so JSON.parse() can't process them directly. Here's a straightforward, customizable approach to turn them into the object array you need:

Step-by-Step Explanation #

1. Split each string into individual key-value pairs: Use split(',') to break the string apart at each comma.
2. Extract keys and values: For each pair, split at the first colon (:) to separate the key (left side) from the value (right side).
3. Clean up values: Handle ellipsis (…) by removing them, and decide how to treat empty values (e.g., set to null or leave as an empty string).
4. Map over the input array: Apply the parsing function to every string in your input array to get the final object array.

Example Code (JavaScript) #

const inputStrings = [
  "Time:25/10/2019 14:49:47.41,Server:Daniel.Europe.A…itical,Area:Europe,Site:,Station:Aberdeen,Stream:",
  "Time:25/10/2019 14:49:48.16,Server:Daniel.Europe.U…,Area:Europe,Site:United Kingdom,Station:,Stream:"
];

function parseSemiStructuredString(str) {
  const keyValuePairs = str.split(',');
  const parsedObject = {};

  keyValuePairs.forEach(pair => {
    const colonPosition = pair.indexOf(':');
    if (colonPosition === -1) return; // Skip any invalid pairs without a colon

    const key = pair.slice(0, colonPosition).trim();
    let value = pair.slice(colonPosition + 1).trim();

    // Remove ellipsis characters (adjust if you want to keep them instead)
    value = value.replace(/…/g, '');
    // Handle empty values: set to null or leave as empty string
    parsedObject[key] = value === '' ? null : value;
  });

  return parsedObject;
}

// Convert the input array to the desired object array
const resultArray = inputStrings.map(parseSemiStructuredString);
console.log(resultArray);

Output #

Running this code will give you:

[
  {
    "Time": "25/10/2019 14:49:47.41",
    "Server": "Daniel.Europe.Aitical",
    "Area": "Europe",
    "Site": null,
    "Station": "Aberdeen",
    "Stream": null
  },
  {
    "Time": "25/10/2019 14:49:48.16",
    "Server": "Daniel.Europe.U",
    "Area": "Europe",
    "Site": "United Kingdom",
    "Station": null,
    "Stream": null
  }
]

Customization Tips #

• If you need to keep ellipsis instead of removing them, delete the value.replace(/…/g, '') line.
• If empty values should stay as empty strings instead of null, change parsedObject[key] = value === '' ? null : value; to parsedObject[key] = value;.
• If your strings ever have commas inside values (e.g., Description:Hello, world), you'll need a more robust parser (like using a regex that ignores commas inside quotes), but this solution works perfectly for your provided input.
