The difference between js submission and submit button submission:
1. js will not be used when submitting the form The value of the submit button (because it has not been clicked) in all browsers
2. Press Enter to submit. The w3c browser will bring the value of the submit button, but ie6 will not.
Solution: Add a hidden domain, Use this to judge, no matter which method is used to submit, there will be a value
Bind the submit event on the submit button:
That is:
will bring the value of submit, and the onsubmit status cannot be detected when submitting with js
w3c: Submit once
ie6: Submit in two times, submit js in the form first
Solution: If the button is submit, use onsubmit event detection when detecting
If the button is button, the submit event will be triggered after the detection is passed
Be sure not to use js to submit the form, and then use onsubmit to detect
Simply use js to submit the form, alert, ff will block the submission of the form, while other browsers
