This is a error about function not defined

Question

In my html file, I have defined onclick event for forgot password() function which is defined in another js file sigin.js but on live server it is giving error:

VM19 signin.html:20 Uncaught ReferenceError: forgotPass is not defined
    at HTMLAnchorElement.onclick (VM19 signin.html:20:67)

This is my html code:

Signin





    <img src="users.png">
    <h2>Sign in</h2>
    

        <input type="text" id="username" class="input-box" placeholder="username"><br>
        <input type="email" id= "email" class="input-box" placeholder="email id"><br>
        <input type="password" id="password" class="input-box" placeholder="passsword"><br>
        <a href="#" class="forgetpass" onclick="forgotPass()">forget password?</a>
    
        <button type="submit" id="signIn" class="signin-btn">Sign in</button>

    </form>
</div>

   .catch((error) => {

 }

I have tried a lot but I don't found any solution for this problem. Please try to find out the problem so that I can go ahead:)

Answer 1

You also have not passed in auth to your sendPasswordResetEmail method which will cause an API error.

It's odd that your debugger/IDE didn't pick up that you were missing an argument, perhaps it's because you're using inline JS.

It's always good to move JS into seperate files callable from the HTML file. You can do this with html script tags.
