Javascript Form Submit - Confirm or Cancel Submission Dialog Box

JavaScript Form Submit - Confirm or Cancel Submission Dialog Box

A simple inline JavaScript confirm would suffice:

<form onsubmit="return confirm('Do you really want to submit the form?');">

No need for an external function unless you are doing validation, which you can do something like this:

<script>
function validate(form) {

    // validation code here ...


    if(!valid) {
        alert('Please correct the errors in the form!');
        return false;
    }
    else {
        return confirm('Do you really want to submit the form?');
    }
}
</script>
<form onsubmit="return validate(this);">

Add a confirmation alert before submitting a form

Instead of alert, you have to use confirm and return in your form, for an example:

<form 
    method="post"
    onSubmit="return confirm('Are you sure you wish to delete?');">
...
</form>

Why JS confirm() won't Cancel the submit action when I hit Cancel in confirm dialog?

Handle it on the form instead of the button, and have the handler return the outcome from the confirm dialog:

<form onsubmit="return confirm('stop or proceed');">

You can also handle the events of each button, but don't forget to return:

<button onclick="return confirm('blabla');">Button</button>

Confirm alert before submit form javascript

You can use SweetAlert with AJAX in Laravel

How can I add confirmation dialog to a submit button in html5 form?

Have onsubmit attribute in your form tag like this if you just want a confirmation from user.

https://jsfiddle.net/yetn60ja/

<form id="id"
    method="POST" action="/y/b/"
    enctype="multipart/form-data"
    onsubmit="return confirm('Do you really want to submit the form?');"
>
    <input class="btn btn-primary"
        type="submit" name="submit" value="A"
    />
</form>

EDIT: Or try below code

<form id="id"
    method="POST" action="/y/b/"
    enctype="multipart/form-data"
>
    <input class="btn btn-primary"
        type="submit" name="submit" value="A"
        onclick="return confirm('Do you really want to submit the form?');"
    />
</form>

On 'Cancel' confirm() still allows form to submit

You need to precede the next() with a return in your HTML:

function next() {  return confirm('Are you sure you want to Foo');}

<form method="GET" action="/foo" onsubmit="return next()">  <input type="hidden" name="delete" value={{$foo} />  <button class="btn btn-warning" type="submit"> Foo</button></form>

$("#button").click(function(event){
    if(!confirm ("your message"))
       event.preventDefault();
});
