Solution for submit () objects that do not support this attribute or Method

This strange problem is encountered today ~
The. Submit () object does not support this attribute or method!
Depressed for a long time ~ After checking the information, the solution is as follows:
------------------------------------------------------
Because form contains a submit button named submit
<Input type = "Submit" name = "Submit" value = "Submit"/>
This is automatically generated by dreamwaver ~ Submit is the reserved field of the default submit form button.
Therefore, you can change the name as long as it is not a submit.
<Input type = "Submit" name = "submit2" value = "Submit"/>
The problem is solved ~
