The HTML <script> Element
The <script> element is employed to declare client-side JavaScripts.
The subsequent JavaScript code writes “Hello JavaScript!” into an HTML element identified by id=”demo”:
Example
<script>
function myFunction() {
document.getElementById(“demo”).innerHTML = “Hello JavaScript!”;
}
</script> |
The HTML <base> Element
The <base> element defines the base URL and/or target for all relative URLs within a page.
The <base> tag must contain either an href attribute, a target attribute, or both.
A document can contain only a single <base> element.
Example
Define a default URL and target for all links within a page:
<head>
<base href=”https://www.code7school.com/” target=”_blank”>
</head>
<body>
<img src=”images/stickman.gif” width=”24″ height=”39″ alt=”Stickman”>
<a href=”tags/tag_base.asp”>HTML base Tag</a>
</body> |
