In HTML5, returning false in a form gives the red line, indicating there is an error, even though I am able to achieve my expected output. Is there any way to fix this line and have a bug free code as it is triggering my OCD. Also, I am a big beginner with my code so please try to keep it as simple as possible. i do not understand JQUERY at all.

return false here brings a red line. even tried it with the "return <function()> and that also gave red line

    does hovering over the red line give helpful message? `i do not understand JQUERY at all.` - you're not using it, so, don't worry about that - you could try `onsubmit="return userRegister1()"` and have `userRegister1` function `return false` – Bravo Mar 26 '22 at 05:37
  • It might just be warning you that if you're doing anything more complicated than calling a single function, you should use an event listener instead of inline JavaScript. But without the detailed explanation of the squiggle, it's hard to know. – Barmar Mar 26 '22 at 05:50
  • @Bravo perhaps jQuery was mentioned because of this? https://stackoverflow.com/a/56296637/3196753 – tresf Mar 26 '22 at 05:58

<form action="#" method="get">
        <input type="text" name="name">
        <button type="submit" onclick="
            // you can code javascript code here, this's same how you code in <script>.....</script>
            function userRegister1(){
                console.log('your code in userRegister1 function');
            }
            userRegister1();

            // so you return false that's wrong syntax
            //onsubmit='userRegister1(); return false;'
            // return must be use in function, in this case you can use in function userRegister1()

            // BUT i don't suggest use this way
        ">Click me</button>
    </form>
