I am done with below solution but now i am facing 1 more problem. When i do changes to text file that don't become effective, while the browser takes the old values only? How to sort it out?

Answer 1

You need AJAX to load the file:

xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", path, true);
xmlhttp.send();
xmlhttp.onreadystatechange=function() {
    if (xmlhttp.readyState==4 && xmlhttp.status==200) {
        parse(xmlhttp.responseText);
    }
}

And then Split the text:

function parse (text) {
    var array = text.split(",");
    //Do something
}

出于安全原因 ，您不能使用Javascript（不是在谈论服务器端js，例如node.js）来读取本地文件系统文件，而是可以使用某些服务器端语言（例如PHP，JSP等）来读取本地文件系统文件。
