8.完善的事件处理功能 jquery已经为我们提供了各种时间处理方法，我们无需在html元素上直接写事件，而可以直接为通过jquery获取的对象添加事件。如：$("#msg").click(function(){alert("good")}) //为元素添加了单击事件 jquery中有几个自定义的事件：（1）hover(fn1,fn2):当鼠标移到一个匹配的元素上面时，会触发指定的第一个函数。当鼠标移出这个函数时，会触发指定的第二个函数。 //当鼠标放在表格的某行上时将class置为over,离开时置为out。 $("tr").hover(function(){ $(this).addClass("over"); }, function(){ $(this).addClass("out"); }); （2）ready(fn):当DOM载入就绪可以查询及操纵时绑定一个要执行的函数。（3）toggle(evenFn,oddFn): 每次点击时切换要调用的函数。如果点击了一个匹配的元素，则触发指定的第一个函数，当再次点击同一元素时，则触发指定的第二个函数。随后的每次点击都重复对这两个函数的轮番调用。（4）trigger(eventtype): 在每一个匹配的元素上触发某类事件。例如： $("p").trigger("click"); //触发所有p元素的click事件（5
