How to use JavaScript to change the meta tags of the page?
To use JavaScript to change the meta tags of the page, we can set the properties that are available in a meta element.
For instance, we write
document.getElementsByTagName("meta")["keywords"].content =
"My new page keywords!!";
document.getElementsByTagName("meta")["description"].content =
"My new page description!!";
to select the meta tag with the name attribute set to keywords with
document.getElementsByTagName("meta")["keywords"]
and set its content attribute value.
Likewise, we select the meta tag with the name attribute description with
document.getElementsByTagName("meta")["description"]
and set its content attribute value.
