    • submit

      public void submit(SubmittableElement submitElement)
      INTERNAL API - SUBJECT TO CHANGE AT ANY TIME - USE AT YOUR OWN RISK.

      Submits this form to the server. If submitElement is null, then the submission is treated as if it was triggered by JavaScript, and the onsubmit handler will not be executed.

      IMPORTANT: Using this method directly is not the preferred way of submitting forms. Most consumers should emulate the user's actions instead, probably by using something like DomElement.click() or DomElement.dblClick().

      Parameters:
      submitElement - the element that caused the submit to occur

    • getWebRequest

      public WebRequest getWebRequest(SubmittableElement submitElement)
