Use JavaScript to write to text file?
I have a need to capture the topics of a search from one of my blog pages and write it to text file for followup. I have been able to capture the input string, however, am not able to write it to a text file. I have read and tried to implement all the solutions I have found with no success. I include a very simple sample of code to write text to file but I can't get it to work. The Onblur event functions fine to access myFunction, so that's not problem. I'm going crazy as samples shown from others are so simple.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" >
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type" />
<title>fs=Server CreateObject ("Scripting FileSystemObject")</title>
<script type="text/javascript">
function myFunction()
{
var fs = ActiveXObject("Scripting.FileSystemObject");
var f = fs.OpenTextFile("d:\\test\\topics.txt", 8, true);
f.WriteLine("This text will be added to the end of file");
f.Close();
}
</script>
</head>
<body>
<input name="Text1" type="text" size="55" onblur="myFunction()" />
</body>
</html>
Answer
If your're using modern browsers which support data-uri, you can create content with javascript and force a download by base64 encoding it and making it compatible with data-uri, then simply pointing window location at it.
This answer demonstrates an HTML-only way to do it.
You can also use a flash helper to take care of this. For instance, Downloadify does this.
