需求：点击按钮，导出文本到本地。 代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>Document</title> </head> <body> <button onclick="downLoadTxt()">导出txt</button> <script src="./FileSaver.js"></script> <script> // var FileSaver = require('file-saver'); function downLoadTxt() { var blob = new Blob(["Hello, world!"], { type: "text/plain;charset=utf-8" }); saveAs(blob, "hello world.txt"); } </script> </body> </html>FileSaver.js可以百度搜索下载。
