Menu
I want to change the meta tag content i.e. refresh rate and url dynamically using javascript. Using a button to enable javascript function. Tried 3 alternatives but not working. Please help.
Thanks,Amresh
<!DOCTYPE html>
<html>
<head>
<meta HTTP-EQUIV="refresh" name="description" id="mymetatag"
content="5;URL=http://localhost:6985/ChartJSDemo/Is_Mainpage.html">
<meta charset="ISO-8859-1">
<title>Processing Details</title>
<link rel="stylesheet" type="text/css" href="css/MF_job_failTable.css">
</head>
<body>
<button onclick="myFunction()">Click me</button>
<script>
function myFunction() {
<!--document.querySelector('meta[name="description"]').setAttribute("content","5;URL=http://google.co.in");-->
<!--document.getElementById("mymetatag").setAttribute("content", "5;URL=http://google.co.in");-->
var m = document.createElement('meta');
m.name = 'description';
m.id = 'mymetatag';
m.content = '5;URL=http://google.co.in';
m.HTTP-EQUIV= 'refresh';
document.head.appendChild(m);
}
</script>

This works for me.
The issue could have been that you tried a first code which did not work and you commented the code with HTML comments <!-- [...] -->instead of Javascript comments: // [...] or /** [...] */.
