Hi i have a two page basic website with a submission box where you write down a name, then a second page that displays "Welcome___", however my website displays ?Welcome=___, I know i need to parse a query string but I'm not sure how to
form.html
<body>
<form action="action.html" method="GET">
<input type="text" name="Welcome" />
<input type="submit" value="Submit" />
</form>
</body>
action.html
<body>
<div id="write">
<p> Welcome </p>
</div>
<script>
document.getElementById("write").innerHTML = window.location.search;
</script>
</body>
To parse the querystring and extract from it the parameter you want the URLSearchParams interface offers useful methods to help you do what you want. A simple implementation might look like this.
<form action='action.html' method='GET'>
<input type='text' name='Welcome' />
<input type='submit' />
</form>
<div id='write'>
<p>Welcome </p>
</div>
<script>
let args=new URLSearchParams( location.search );
if( args.has('Welcome') ){
document.getElementById('write').querySelector('p').textContent += args.get('Welcome');
}
</script>
