需求：

我们有一个这样的字符串

`以下数据：{"title": "标题一", "text": "内容一", "tag": "tag1"}{"title": "标题二", "text": "内容二", "tag": "tag二"}`

需要提取里面的字符串

function extractDataFromString(str) {const regexTitle = /"title": "(.*?)"/g;const regexText = /"text": "(.*?)"/g;const regexTag = /"tag": "(.*?)"/g;let titles = [];let texts = [];let tags = [];let match;while ((match = regexTitle.exec(str))) {titles.push(match[1]);}while ((match = regexText.exec(str))) {texts.push(match[1]);}while ((match = regexTag.exec(str))) {tags.push(match[1]);}let result = [];for (let i = 0; i < titles.length; i++) {let obj = {title: titles[i],text: texts[i] || "",tag: tags[i] || ""};result.push(obj);}return JSON.stringify(result);
}const jsonData = extractDataFromString(inputString);
console.log(jsonData);
