javascript write to text file
A JavaScript function that fire on the button click event. I’ll show you how to do that in a couple minutes! To create a text file from javascript, we’ll need to use Blob object.
Example
function WriteToFile(passForm) { set fname = CreateObject("Scripting.FileSystemObject"); set solution = fname.CreateTextFile("<your Path>/pakainfo.txt", True); var MemberUserName = document.getElementById('MemberUserName'); var memberSirname = document.getElementById('memberSirname'); solution.writeline("Member User Name :" + MemberUserName); solution.writeline("Member Sir Name :" + memberSirname); solution.writeline("-----------------------------"); solution.Close(); } // HTML Source Code <form onSubmit="WriteToFile(this)"> <label>Type your Member name:</label> <input type="text" name="MemberUserName" id="MemberUserName" size="20"> <label>Type your Member sir name: </abel> <input type="text" name="memberSirname" id="memberSirname" size="20"> <input type="submit" value="submit"> </form>
javascript write to file
first of all Requiring fs module in which writeFile function is defined. and Data which will write in a file and // Write data in ‘Results.txt’.
<script> const fs = require('fs') let data = "Welcome To Pakainfo.com free download source code." fs.writeFile('Results.txt', data, (err) => { // In case of a error throw err. if (err) throw err; }) </script>
write to file
var mainExFlData = "c:/product.txt"; var flName = new File(mainExFlData); var userString = "Welcome To Pakainfo.com"; flName.open("w"); // open file with write access flName.writeln("First line of text"); flName.writeln("Second line of text " + userString); flName.write(userString); flName.close();
read from file
var mainExFlData = "c:/product.txt" var flName = new File(mainExFlData); flName.open("r"); // open file with read access var userString = ""; while (!flName.eof) { // read each line of text userString += flName.readln() + "\n"; } flName.close(); alert(userString);
writeTextFile write data to file on hard drive
function writeTextFile(filepath, output) { var mainExFlData = new File(filepath); mainExFlData.open("w"); // mainExFlData.writeln(output); mainExFlData.close(); }
readTextFile read data from file
function readTextFile(filepath) { var userString = ""; var mainExFlData = new File(filepath); mainExFlData.open("r"); while (!mainExFlData.eof) { // read each line of text userString += mainExFlData.readln() + "\n"; } return userString; }
JavaScript write to text file
<html> <h2>Create Text file in JavaScript</h2> <script> function createFile(){ var object = new ActiveXObject("Scripting.FileSystemObject"); var file = object.CreateTextFile("C:\\Welcome.txt", false); file.WriteLine('Welcome To Pakainfo'); file.WriteLine('Free Download Source code for Pakainfo,com'); file.Close(); } </script> <input type="Button" value="Make File" onClick='createFile()'> </html>
