submit is not a function in javascript

Why is the following basic javascript function giving me an error document.getElementById("form").submit is not a function.

The only thing i have on a page is a form and this javascript function. I want he form to auto submit when page is accessed.

<script>
 window.onload = function(){
 document.getElementById('form').submit();
}
</script>

回答1:

Make sure that there is no name="submit" or id="submit" in the form

回答2:

This is probably because the form contains input with name=submit; then the submit property contains object of the element. Rename it or use

document.createElement('form').submit.call(document.getElementById('form'));
