How to prevent google app script reloading/redirecting my webpage after form data submission ..?

Question

I am using google app script to submit form data to my email. It's a webpage contact form. But by default after hitting the submit button it takes to a different page and shows a "result:success" weird kinda message. I want to prevent that reload or redirect. How can I do that?

HTML

<form id="email-form" class="gform" action="https://script.google.com/macros/s/AKfyJu890G2t-RuhJxTNIA/exec" method="post">
        <div class="email-name">
            
            <input id="name" name="name" type="text" class="form-control" placeholder="write name" autocomplete="off">
        </div>
        <div class="email-main">
            
            <input id="email" name="email" type="text" class="form-control" placeholder="write email" autocomplete="off">
        </div>
        <div class="email-subject">
            
            <input id="subject" name="subject" type="text" class="form-control" placeholder="write related sub" autocomplete="off">
        </div>
        <div class="email-message">
            
            <textarea id="message" name="message" class="form-control" placeholder="write message here"></textarea>
        </div>

        <button id="send-email" type="submit">SUBMIT EMAIL</button>

        
    </form>

I can add an alert using onclick event but still the reload happens. Please provide javascript code for preventing the default behavior for this form.

I've been able to get around this before by moving the submit button out of the form.

<form id="email-form" class="gform" action="https://script.google.com/macros/s/AKfyJu890G2t-RuhJxTNIA/exec" method="post">
        <div class="email-name">
            
            <input id="name" name="name" type="text" class="form-control" placeholder="write name" autocomplete="off">
        </div>
        <div class="email-main">
            
            <input id="email" name="email" type="text" class="form-control" placeholder="write email" autocomplete="off">
        </div>
        <div class="email-subject">
            
            <input id="subject" name="subject" type="text" class="form-control" placeholder="write related sub" autocomplete="off">
        </div>
        <div class="email-message">
            
            <textarea id="message" name="message" class="form-control" placeholder="write message here"></textarea>
        </div>
    </form>

        <button id="send-email" type="submit">SUBMIT EMAIL</button>

If that does not work you can try using target to a hidden iframe.
