I am a javascript beginner and want to submit a php form by a usual button not submit button.
I wanted to do this by document.<formname>.submit() ,but this did not work and I get an error in javascript console that saied submit() is not a function.

Does this helps?

• Submit a Form Using JavaScript
• Form Submissions Without Submit Buttons

Any reason you don't want to use the normal html submit button?

Thanks Monie,
First, I have to use this method because I use AJAX to send some information to web server and authonticate via mysql. So I have to use another submission method than usual submit button.

Second, Again thanks for your links but they could not help me because I do all the things correct but the submit() does not trigger and I get the following error from javascript console :
document.<formname>.submit() is not a function?

I do not know what I have done that this happen. All the things are correct and work but this.

Did you have this kind of button somewhere else in your page?

HTML: Select all

<input type="submit" name="submit" value="submit">

if you do, that might be the problem!

document.<formname>.submit() is not a function?

The reason was the statement "<formname>.submit();" in the javascript was colliding with the form button, which was also named "submit".

<input type="submit" name="submit" value="Login">

Sollution: Change the name of the button to "login" or something else more reflective of it’s functionality instead of "submit".

Just guessing here since I don't have your full HTML file.

So your submit function would be like this:

HTML: Select all

function submitForm(formId) {
  var formObj = document.getElementById(formId);
  formObj.submit();
}

and your HTML:

Code: Select all

<a href="http://www.homepage.com"
onclick="submitForm('loginForm'); return false">Login</a>

<form id="loginForm">
<input type="submit" name="login" value="Login">
</form>
