Question

我需要将单独的文件路径和文件名插入到大量 HTML 文件中。路径应在</title> 标记之后输入。

最快的方法是什么？

解决方案 1

const fs = require("fs");
const nodePath = require('path');
const path = 'C:\\Users\\Sudhakar_r_R\\Desktop\\test';

function change(path) {
    const files = fs.readdirSync(path);
    files.forEach((i) => {
        let x = nodePath.join(path, i);
        if (fs.statSync(x).isFile()) {
            fs.readFile(x, 'utf-8', function (err, data) {
                if (err) throw err;
                let newStuff = data.replace('</title>', `</title><!-- fullpath: ${x} filename: ${nodePath.basename(x)} path: ${nodePath.dirname(x)} -->`);
                fs.writeFile(x, newStuff, 'utf-8', function (err) {
                    if (err) throw err;
                    console.log(x,"done");
                });
            })
        }
        else {
            change(x);
        }
    });
}

change(path);

解决方案 2（使用“jsdom”）

const jsdom = require("jsdom");
const fs = require("fs");
const { JSDOM } = jsdom;
JSDOM.fromFile("./old.html", { runScripts: "dangerously" }).then(dom => {
    let node = dom.window.document.getElementsByTagName('title')[0];
    // you can create html elements or put it in string format
    node.insertAdjacentHTML('afterend', '</title><script src="test.js"></script>');
    fs.writeFile('new.html', dom.serialize(), 'utf-8', function (err) {
        if (err) throw err;
        console.log('Now, you can check the output');
    });
});
