HTML includes are done by JavaScript.
Example
<script>
function includeHTML() {
var z, i, elmnt, file, xhttp;
/* Loop through a collection of all HTML elements: */
z =
document.getElementsByTagName("*");
for (i = 0; i < z.length; i++)
{
elmnt = z[i];
/*search for
elements with a certain atrribute:*/
file =
elmnt.getAttribute("w3-include-html");
if (file) {
/* Make an HTTP request using the attribute value as the file name: */
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4) {
if (this.status == 200) {elmnt.innerHTML = this.responseText;}
if (this.status == 404) {elmnt.innerHTML = "Page not found.";}
/* Remove the attribute, and call this function once more: */
elmnt.removeAttribute("w3-include-html");
includeHTML();
}
}
xhttp.open("GET", file, true);
xhttp.send();
/* Exit the function: */
return;
}
}
