Menu
I have 2 pages, when the second page load in first page, the JavaScript of that pages run after all the JavaScript and load very slowly. I wrote the below code to show the spinner till the second page load completely. But the spinner doesn't s work. Here is my code:
<script>
$('.tourajaxi').html('<i class="fa fa-spinner fa-pulse fa-3x fa-fw" ></i><span class="sr-only">Loading ...</span>');
$(window).load(function() {
$('.tourajaxi').load('/toursajax.bc?gid=325');
});
</script>

There are two different types of issues that can cause admin-ajax. php slow server responses. The first is a backend CPU issue and the second is more of a frontend issue where you will notice third party plugins polling this file in your website speed tests.
In my app, there are a lot of ajax calls. A user may do 50 ajax calls per session, so speed is very important. The ajax call queries the database and returns a list of records.
Javascript provides client-side support whereas AJAX provides server-side support by exchanging data with the server. Javascript is applicable when there is an HTML and AJAX functionality that takes data using XMLHttpRequest. Javascript is a well-known programming language whereas AJAX is not a programming language.
A guess, since you haven't included any HTML:
Your script is in the <head> of the document, and tries to apply HTML to the element "tourajaxi", but that element does not exist until the rest of the document is loaded.
