Is there a way to use JavaScript to display a form for entering a name when a page loads, and then hide the form when the user clicks submit?
<div id="small-form">
<form>
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname"><br>
<input type="submit" value="Submit" onclick="hideForm()">
</form>
</div>
To hide the form, use the hideForm() function and apply the display:none style to the div called small-form.
Here's how you can do it:
var formElement = document.getElementById("small-form");
formElement.style.display = "none";
To prevent the form from submitting to the server without hiding it, you have a couple of options. You can either use Ajax to submit the form in the background, target an iframe or open a new tab.
If the form submission results in loading the same page, you can choose to hide the form on the server side or store a directive in localStorage instructing the page not to display the form.
I would strongly advise against using the onclick event for a submit button; instead, utilize the submit event for better control and functionality.
document.getElementById("myForm").addEventListener("submit", function(e) {
e.preventDefault(); // To prevent form submission
document.getElementById("small-form").classList.add("hide");
// Perform other actions such as AJAX requests here
}).hide { display: none; }<div id="small-form">
<form id="myForm">
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname"><br>
<input type="submit" value="Submit">
</form>
</div>To conceal the form using JavaScript, you can simply set the display style to none within the hideForm() function.
However, if your form contains a submit button, it will trigger a redirection upon being clicked. To prevent this behavior (in case you don't want the form to be submitted), you can change the input type from "submit" to "button".
function hideForm()
{
document.getElementById('small-form').style.display = 'none';
}<div id="small-form">
<form >
<label for="fname">First name:</label><br>
<input type="text" id="fname" name="fname"><br>
<input type="button" value="Submit" onclick="hideForm();">
</form>
</div>If you want to hide the form permanently, one way to do it is by setting the display property of the form to none. This will effectively hide the form while still keeping it in the HTML code.
function hideForm() {
event.preventDefault();
var myForm = document.getElementById("My-Form");
myForm.style.display = "none";
var name = document.getElementById("Name");
alert(name.value);
}<div id="small-form">
<form id="My-Form">
<label for="fname">First name:</label><br>
<input id="Name" type="text" id="fname" name="fname"><br>
<input type="submit" value="Submit" onclick="hideForm(event)">
</form>
</div>Another approach to achieving the same result is by removing the form altogether using the remove() function. This action will completely eliminate the form from the HTML.
function hideForm(event) {
event.preventDefault();
var myForm = document.getElementById("My-Form");
var name = document.getElementById("Name");
alert(name.value);
myForm.remove();
}<div id="small-form">
<form id="My-Form">
<label for="fname">First name:</label><br>
<input id="Name" type="text" id="fname" name="fname"><br>
<input type="submit" value="Submit" onclick="hideForm(event)">
</form>
