How do I navigate to hashtag after page load?
For some reason both MS Edge 42 and IE 11 will not scroll to the new bookmark for me, even when doing a window.location.reload(true)
after setting the new bookmark. So I came up with this solution: insert this script on the page you're loading (requires jquery)
$(document).ready(function() {
var hash = window.location.hash;
if (hash) {
var elem = document.getElementById(hash.substring(1));
if (elem) {
elem.scrollIntoView();
}
}
});
If you simply want to change the hash after page loads:
window.onload = function (event) {
window.location.hash = "#my-new-hash";
};
If you want to navigate to the URL with new hash:
window.location.href = "http://website.com/#my-new-hash";
If you want to listen for changes in the hash of the URL; you can consider using the window.onhashchange DOM event.
window.onhashchange = function () {
if (location.hash === "#expected-hash") {
doSomething();
}
};
But it is not supported by every major browser yet. It now has a wide browser support. You can also check for changes by polling the window.location.hash
on small intervals, but this is not very efficient either.
For a cross-browser solution; I would suggest Ben Alman's jQuery hashchange plugin that combines these methods and a few others with a fallback mechanism.
EDIT: After your question update, I understand you want the page to scroll to a bookmark?:
You can use Element.scrollTop
or jQuery's $.scrollTop()
method.
$(document).ready(function (event) {
var yOffset = $("#my-element").offset().top;
$("body").scrollTop(yOffset);
});
