jquery remove, bind, trigger element events

Unbind (type [, data])     //data is the function to be removed $ ('#btn'). Unbind (" Click " // Remove Click$ ('#btn'// Remove all

For a case that only needs to be triggered once and then immediately unbound, use one ()

$ ('#btn'). One ("click", function () {...});

Trigger action: the trigger () method triggers the specified event type for the selected element.

$ ('#btn'). Trigger ("click");

Trigger Custom Event: the bind () method adds one or more event handlers for the selected element and specifies the function to run when the event occurs.

$ ('#btn'). Bind ("myclick", function () {...});

Impersonation triggers the above binding function

$ ('#btn'). Trigger ("myclick");

Pass Data trigger (EVENT,[PARAM1,PARAM2,...])

$ ('#btn'). Bind ("myclick", Function (event, Message1,message2) () {...}); $ ('#btn'). Trigger ("myclick", [" Pass it to Message1 "," passed to Message2"]);

Triggering the execution of the default action

$ ("input"). Trigger ("Focus"); // not only does it trigger the focus event that the input element binds to, it also triggers the default action--Get Focus

Triggers only binding events, not browser default actions

$ ("input"). Triggerhandler ("Focus"); // triggers only binding events, not browser default actions

Other usage

Binding multiple Event types

$ ("div"). Bind ("mouseover mouseout", function () {...});

To add an event namespace

$ ("div"). Bind ("click.plugin", function () {...});

Add a namespace after the event type you are binding so that you only need to specify the namespace when you delete the event.

$ ("div"). Unbind (". Plugin");   // Delete the event within the space $ ("div"). Trigger ("click! " // trigger so does not include the click Method in the namespace

If it is included in the namespace, it will also be triggered

$ ("div"). Trigger ("click");

Cancel or bind a function

$ ('div'). Bind ('click', recommandproduct); // bind the Recommandproduct function $ ('div') for Div. Unbind ('click ', recommandproduct); // Cancel the Recommandproduct function
