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.

Examples

Functionvalidate ()

{

Varat=document.getElementById ("email") .value.indexOf ("@")

Varage=document.getElementById ("age"). Value

Varfname=document.getElementById ("fname"). Value

SubmitOK= "true"

If (fname.length > 10)

{

Alert ("first name must be less than 10 characters.")

SubmitOK= "false"

}

If (isNaN (age) | | age100)

{

Alert ("Age must be a number between 1 and 100.")

SubmitOK= "false"

}

If (at==-1)

{

Alert ("not a valid email address.")

SubmitOK= "false"

}

If (submitOK== "false")

{

Returnfalse

}

}
