How can I create a "first-load" event in html or Javascript?
I'm starter. I have an idea. I want to implement an event like this. Is it possible?
<html>
<head>
<title>First visit event</title>
<script>
function do_something()
{
alert("Hello my friend. This is your first visit.");
}
</script>
</head>
<body firstVisitEvent="do_something()">
</body>
Answer
Use on load. It will execute when the page loads, and you will see your alert. Good luck with your knowledge.
<html>
<head>
<script>
function load()
{
alert("Page is loaded");
}
</script>
</head>
<body onload="load()">
<h1>Hello World!</h1>
</body>
</html>
Edit: You can get more advance and set cookies to see if it's the user's first time, but I'm not sure you're at that level yet, but anyways:
You could for example set a localStorage property like
if(!localStorage["alertdisplayed"]) {
alert("Your text")
localStorage["alertdisplayed"] = true
}
Note that localStorage isn't supported by older Browsers.
An alternative would be setting a Cookie and check against its existence
If you don't know how to set / get cookies with javascript, i would suggest, reading this article: https://developer.mozilla.org/en-US/docs/Web/API/document.cookie?redirectlocale=en-US&redirectslug=DOM%2Fdocument.cookie
