Solution to "uncaught typeerror: Property 'submit 'of object # is not a function"

Today, I encountered a problem and found that many people on foreign websites are asking questions. Some people suspect that this is an unknown bug ..

SeeCode:

<Input type = "button" name = "Submit" onclick = "XXX ()"/>

<SCRIPT type = "text/JavaScript">
XXX () {form. Submit ();}
</SCRIPT>

If you click submit, the following error will be reported:

"Uncaught typeerror: Property 'submit 'of object #  
Actually, it's actually .. All of this is because you wrote the button for type and the submit for name. If you changed the name to the button, it would be okay ~~
 
In this case, writing form. Submit () in XXX () will not report an error.
