Use the pageBreakBefore property in JavaScript to set the page-break behavior before an element. Use the always property to insert a page break before an element.
Note − The changes would be visible while printing or viewing the print preview.
Example
You can try to run the following code to return the page-break behavior before an element with JavaScript −
<!DOCTYPE html>
<html>
<body>
<h1>Heading 1</h1>
<p>This is demo text.</p>
<p>This is demo text.</p>
<p id = "myFooter">This if footer text.</p>
<button type="button" onclick = "display()">Set page-break</button>
<script>
function display() {
document.getElementById("myFooter").style.pageBreakBefore = "always";
}
</script>
</body>
</html>
