$(document).on("mouseover",".close",function()什么意思？怎么调用？

[「已注销」]

$(document).on("mouseover",".close",function()
{
var icon = $(this);
icon.find("div").find("img").attr("src","/iims/home/image/close_hover.png");
});

$(document).on("mouseout",".close",function()
{
var icon = $(this);
icon.find("div").find("img").attr("src","/iims/home/image/close.png");
});

不懂什么意思? 请查jquery的on方法... 简单的说就是为.close绑定mouseover 处理方法在function里面.

on: function( types, selector, data, fn, /*INTERNAL*/ one ) {
		var type, origFn;

		// Types can be a map of types/handlers
		if ( typeof types === "object" ) {
			// ( types-Object, selector, data )
			if ( typeof selector !== "string" ) {
				// ( types-Object, data )
				data = data || selector;
				selector = undefined;
			}
			for ( type in types ) {
				this.on( type, selector, data, types[ type ], one );
			}
			return this;
		}

		if ( data == null && fn == null ) {
			// ( types, fn )
			fn = selector;
			data = selector = undefined;
		} else if ( fn == null ) {
			if ( typeof selector === "string" ) {
				// ( types, selector, fn )
				fn = data;
				data = undefined;
			} else {
				// ( types, data, fn )
				fn = data;
				data = selector;
				selector = undefined;
			}
		}
		if ( fn === false ) {
			fn = returnFalse;
		} else if ( !fn ) {
			return this;
		}

		if ( one === 1 ) {
			origFn = fn;
			fn = function( event ) {
				// Can use an empty set, since event contains the info
				jQuery().off( event );
				return origFn.apply( this, arguments );
			};
			// Use same guid so caller can remove using origFn
			fn.guid = origFn.guid || ( origFn.guid = jQuery.guid++ );
		}
		return this.each( function() {
			jQuery.event.add( this, types, fn, data, selector );
		});
	},

谢谢楼上各位回答。基本懂了，由于之前没接触jquery1.10.
