The rewritten title is: Use buttons outside the <form> tag to submit the form

Question

Translation result:

<p>Suppose I have the following: <code><form method="get" action="something.php">
    <input type="text" name="name" />
</form>

<input type="submit" /></code>

How do I submit this form using a submit button located outside the form? I know there is a submit action attribute in HTML5, but I'm not sure if it's fully cross-browser compatible. If not, is there any other way to achieve this functionality?

Answer 1

In HTML5, there is form attribute. basically

<form id="myform" method="get" action="something.php">
    <input type="text" name="name" />
</form>

<input type="submit" form="myform" value="Update"/>

Answer 2

Update: In modern browsers, you can use the form attribute to achieve this .

As far as I know, you can't achieve this functionality without using JavaScript.

This is the description in the specification

This is the part I bolded

submitButtons are considered controls.

Based on comments

Why not put the input inside the form, but use CSS to place it elsewhere on the page?
