$ ("img"). Toggle (function () { $ ("img"). attr ("src", "imags/1.jpg"); $ ("img"). attr ("title", This.src);},function () { $ ("img"). attr ("src", "imags/2.jpg"); $ ("img"). attr ("title", This.src);},function () { $ ("img"). attr ("src", "imags/3.jpg"); $ ("img"). attr ("title", This.src);}); Click the picture, change one at a time, execute three functions in turn

Unbind (); Removes the Click event //$ ("input") for all input forms. Unbind ("click", Oclick); Only remove the event of button two});<input type= "button" value= "buttons One" class= "BNT"/><input type= "button" value= "button two" class= "BNT"/><input Type= "button" value= "Delete event" class= "BNT"/><div id= "Divtip" > </div>
One (type,[data],function) methodThis method is used to trigger only one event binding, similar to the bind () method
Trigger (Type,[data]) methodDelegate (Childselector,event,data,function) method$ ("button"). Click (function () { $ ("input"). Trigger ("select");});$ ("div"). Delegate ("button", "click", Function () { $ ("P"). Slidetoggle (); });
