</title>
<script type="text/javascript">
function disable(){
var a=document.getElementById("link");
a.setAttribute("class","disabled");
a.setAttribute("style","color:black;pointer-events:none;");
}
</script>
</head>
<body>
<a href="www.google.com" id="link">www.google.com</a>
<button onclick="disable()" >Disable</button>
</body>
</html>
- <!DOCTYPE html> tag which is instruct the web browser about what version of HTML file written in and it’s not have any ending tag.

- As above shown <head> tag is contain information about webpage and some websites when need to use external files those links are declared here. <title> tag is used for set the webpage title.
- Both <head> and <title> tags having their pair end tag, so we need to close the ending tags respectively. If your not closed anyone of ending tag properly that is also affect the webpage result.

- Here when user clicks disable button onclick event will loads the disable() function.
- Var used to declare an variable in javascript, ‘a’ is variable name. In document.getElementById() document is document object used for access any HTML element in webpage and getElementById() is a method return the value of elements ID attribute.
- So we used document.getElementById(‘link’) to get the value of <a> tag. setAttribute() is method for sets the value of an attribute on specified element.
- a.setAttribute("class","disabled") line sets value of ‘disabled’ to class attribute on element ‘a’and a.setAttribute("style","color:black;pointer-events:none;") line sets value color to black, pointer-events to none on the element ‘a’.
- So we achieve the result, when click disable button disable() function will load then <a> tag disabled, color changed to black & pointer-events response also stopped.
- Both </body>,</html> tags closed respectively. </body> tag indicates the end of body, Then </html> tag indicates the end of HTML document.
