Question

尝试从javascript中的文本文件读取时遇到错误。

这是代码

<!Doctype html>
<html>
    <head>

        Dwell time for workers

    </head>
    <script src = "https://requirejs.org/docs/release/2.3.6/comments/require.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
    <script type="text/javascript" src="workers_dwell_time_final1.json"></script>
    <script type = "text/javascript"></script>
    <script>

    //var mydata = JSON.parse(data);
    //console.log(mydata[0].name);
    //console.log(mydata[0].time);
    //  <script src = "https://requirejs.org/docs/release/2.3.5/minified/require.js" > /script>
    const fs = require('fs') 

    // Reading data in utf-8 format 
    // which is a type of character set. 
    // Instead of 'utf-8' it can be  
    // other character set also like 'ascii' 
    fs.readFile('myfile.txt', 'utf-8', (err, data) => { 
        if (err) throw err; 

    // Converting Raw Buffer to text 
    // data using tostring function. 
    console.log(data); 
}) 



    </script>


<body>
    <h1> worker time : </h1>

</body>


</html>

这是错误

require.js:168 Uncaught Error: Module name "fs" has not been loaded yet for context: _. Use require([])

我该如何删除错误。如果有人拥有适当的require.js文件，请共享它

Answer 1

您要执行的操作是加载未与应用程序捆绑在一起的模块。而且我也不认为您可以这样阅读。不在网页中（与nodejs相比）。您需要从服务器（该文件是公用文件夹，请参见：https://www.w3schools.com/html/html_filepaths.asp）中的服务器提供该文件。
