[html] Submit button doesn't work

I have a form with <input type="submit". In chrome submit doesn't do anything. On a "network" in tab in developer tools I see nothing. No errors in developer tools either. Meanwhile, if I do save a page and open a saved page, then after I press submit button, I see something appears in "network" tab. This happens in chrome and firefox. This works as expected in IE.

Does anybody have a hindsight, what should I look at?

EDIT: I don't need a direct answer, I only need to know, where should I look at. If someone posts a direction and that'll help me to solve my problem, I'll accept it as a correct answer.

EDIT2: Structure of a page looks like this:

html
    head
    body
        div
        div
            form
            form
            form
            form
            form
                input
                input
                table
                table
                    tbody
                        tr..td..input type=submit

EDIT3: We found the actual problem, it was that in a page was a link, containing href="#" and after clicking on that link submit stopped to work, because # was added to the end of URL and because action of the form was empty so it picked up URI from current URI, which contained # at the, so instead of submitting, browser did jump on a current page.

I ran into this on a friend's HTML code and in his case, he was missing quotes.

For example:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
<input type="text" name="fname" id="fname" style="width:90;font-size:10>     
<input type="submit" value="submit"/>
</form>

In this example, a missing quote on the input text fname will simply render the submit button un-usable and the form will not submit.

Of course, this is a bad example because I should be using CSS in the first place ;) but anyways, check all your single and double quotes to see that they are closing properly.

Also, if you have any tags like center, move them out of the form.

<form action="formHandler.php" name="yourForm" id="theForm" method="post">  
<center> <-- bad

As strange it may seems, it can have an impact.

Are you using HTML5? If so, check whether you have any <input type="hidden"> in your form with the property required. Remove that required property. Internet Explorer won't take this property, so it works but Chrome will.

Hello from the future.

For clarity, I just wanted to add (as this was pretty high up in google) - we can now use

<button type="submit">Upload Stuff</button>

And to reset a form

<button type="reset" value="Reset">Reset</button>

Check out button types

We can also attach buttons to submit forms like this:

<button type="submit" form="myform" value="Submit">Submit</button>

I faced this problem today, and the issue was I was preventing event default action in document onclick:

document.onclick = function(e) {
    e.preventDefault();
}

Document onclick usually is used for event delegation but it's wrong to prevent default for every event, you must do it only for required elements:

document.onclick = function(e) {
    if (e.target instanceof HTMLAnchorElement) e.preventDefault();
}

Check if you are using any sort of jquery/javascript validation on the page and try disabling it and see what happens. You can use your browser's developer tools to see if any javascript file with validate or validation is being loaded. You can also look for hidden form elements (ie. style set to display:none; or something like that) and make sure there isn't a hidden validation error on those that's not being rendered.
