1.第一个参数是事件类型，常用的click，blur，hover等<br>2.多个事件类型可以通过将每个空格分隔开来一次绑定<br>3.我们可以通过传递事件类型/处理程序对的对象来同时绑定多个事件处理程序
$( "#foo" ).bind( "click", function() {
<br>alert( "User clicked on 'foo.'" );
<br>});
$( "#foo" ).bind( "mouseenter mouseleave", function() {
<br>$( this ).toggleClass( "entered" );
<br>});
$( "#foo" ).bind({
<br>click: function() {
<br>// Do something on click
<br>},
<br>mouseenter: function() {
<br>// Do something on mouseenter
<br>}
<br>});
