What does submit mean in html
This article is about what submit means in html. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.
The Submit object represents a submit button (submitbutton) in the HTML form. Every time a tag appears in an HTML form, a Submit object is created.
Before the form is submitted, the onclick event handle is triggered, and a handle can cancel the form submission by returning false.
See the Form.submit () method and the Form.onsubmit event handle.
You can access a submit button by iterating through the form's elements [] array, or by using document.getElementById ().
IE:InternetExplorer,F:Firefox,O:Opera,W3C:W3C standard.
