Provided Methods

fn connect_will_send_submit_event<F: Fn(&Self, &Value, &Frame, &Frame) + 'static>( &self, f: F, ) -> SignalHandlerId

This signal is emitted when the DOM submit event is about to be fired for @form. JavaScript code may rely on the submit event to detect that the user has clicked on a submit button, and to possibly cancel the form submission before #WebKitWebFormManager::will-submit-form signal is emitted. However, beware that, for historical reasons, the submit event is not emitted at all if the form submission is triggered by JavaScript. For these reasons, this signal may not be used to reliably detect whether a form will be submitted. Instead, use it to detect if a user has clicked on a form’s submit button even if JavaScript later cancels the form submission, or to read the values of the form’s fields even if JavaScript later clears certain fields before submitting. This may be needed, for example, to implement a robust browser password manager, as some misguided websites may use such techniques to attempt to thwart password managers.

form

the #JSCValue to be submitted, which will always correspond to an HTMLFormElement

source_frame

the #WebKitFrame containing the form to be submitted

target_frame

the #WebKitFrame containing the form’s target, which may be the same as @source_frame if no target was specified

fn connect_will_submit_form<F: Fn(&Self, &Value, &Frame, &Frame) + 'static>( &self, f: F, ) -> SignalHandlerId

This signal is emitted when @form will imminently be submitted. It can no longer be cancelled. This event always occurs immediately before a form is submitted to its target, so use this event to reliably detect when a form is submitted. This signal is emitted after #WebKitWebFormManager::will-send-submit-event if that signal is emitted.
