Javascript Error: submit is not a function

Took me a google search to find this one, but for some reason one of my forms was not submitting using javascript.

The reason was the statement “formObj.submit();” in the javascript was colliding (resulting in ambiguity within the browser) with the form button, which was also named “submit”.


Change the name of the button to “login” or something else more reflective of it’s functionality instead of “submit”.

  • Eduardo Rodrigues


    thank you sooooo much!!!!!!

    I´ve been over this for hours!!!
    In debug, it would show the form as a form, with the submit method and all… but, error on the call. There was nothing poiting that the submit was being misplaced with the form button that had the same name.

    You were a NINJA to find this out!

    Thank you!!!!!!!!!!

    OMG THANK YOU SO MUCH! I searched high and low on Google and I finally found this article that saved my insanity. THANK YOU!

  • HTML was stripped out of my previous message.

    I’ll try to use HTML equivs:

    < input type=”checkbox” name=”toggle_all” onclick=”toggle_all();” >

    < input type=”checkbox” name=”toggle_everything” onclick=”toggle_all();” >

  • It’s not only a matter of reserved words, it’s also a matter of element naming conflicts that you do yourself.

    Found out this after a good half hour of scratching my head:

    will trigger a JS error “toggle_all is not a function” BECAUSE toggle_all is the name of the input element.

    this code works:

    because I set the name of the input element to something else than the function name.

    Hope this saves somebody some time.

    best regards,

    This is it. Thanks

  • Tony

    Thank you for this solution! I’ve been googling this issue for half an hour. Very helpful.

  • r1tman

    I had a submit button named submit and that is what totally jacked my submit code. So all 1001 ways I coded it would never work because document.formname.submit was an object and I guess it found that before finding the submit function? Not sure why but I know what the problem was at least!

  • Thanks, I was starting to get frustrated :)

  • my french isn’t all that great….and your example got truncated COOLDEV, so I’m not sure what you’re trying to show.

  • chovy

    COKE – why don’t you use the javascript debugger in Firefox? just type “javascript:” in the address bar, then reload the page.

  • Coke

    I f$·%ing HATE JAVASCRIPT SO f$·%ing MUCH.

    So incompatible, so weird, you can’t trace the source of the problem quick. Sucks, Sucks and don’t stop sucking.

  • Oscar González

    Your article is very usefull; In Safari the error is
    Object [object INPUT] (result of expression document.form1.submit) does not allow calls.

  • TracyTrace

    Definitely worth googling this. I wasted about 30 minutes on this before finding your post. Thanks!

  • jon

    Thanks!! Luckily, I only lost 40 minutes before I found your incredibly useful article.

  • Ian Good

    Thanks for the tip! I spent an hour trying to figure it out before I googled it. I need to learn to google first.

  • I know – first thing I should’ve checked when I got the unexplainable was “reserved words”.

  • Three hours of searchin my codes and javascripts books about this error, thank you so much, you haved my ***

  • crazy

  • Kevin


    You rock!

  • Thanks for that. Just saved me hours cause I would not have thought of a name clash!

  • Okay, it got me too. Put me down for 5 hours wasted on a Sunday night :)

    I’m sure it was a good idea at the time, but what a hunk of junk HTML and JavaScript are. Thanks a bunch W3C. And no Bill Gates that doesn’t mean you are right, you don’t play well with others so you are completely invalid.

  • jeconais

    Well, this’ll teach me to use google first rather than try and figure it out myself.

    My wife thanks you for keeping my hair on my head, where it belongs.

  • The Swede

    Thanx man. I just spent the last hour wondering why all funktions but submit() worked fine in my form. And there it was: a button named submit…

  • haval

    THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • T Grove

    This article is f***ing amazing, I should hire you at my company!! I have been searching all day for this stupid issue. And of course, with DOT syntax it blows my mind that IE supports this method. Submit is an object of the page, in DOT syntax it should be named differently. Thanks Again – you are a life savor!!

    Now, how in the hell to you change all those other stupid f***ing posts on Google so they get it right???
