新手求教jquery代码含义
var arrowimages={down:['downarrowclass', 'arrow-down.gif', 25], right:['rightarrowclass', 'arrow-right.gif']}
var jquerycssmenu={
fadesettings: {overduration: 350, outduration: 100},
buildmenu:function(menuid, arrowsvar){
jQuery(document).ready(function($){
var $mainmenu=$("#"+menuid+">ul")
var $headers=$mainmenu.find("ul").parent()
$headers.each(function(i){
var $curobj=$(this)
var $subul=$(this).find('ul:eq(0)')
this._dimensions={w:this.offsetWidth, h:this.offsetHeight, subulw:$subul.outerWidth(), subulh:$subul.outerHeight()}
this.istopheader=$curobj.parents("ul").length==1? true : false
$subul.css({top:this.istopheader? this._dimensions.h+"px" : 0})
$curobj.children("a:eq(0)").css(this.istopheader? {paddingRight: arrowsvar.down[2]} : {}).append(
'<img src="'+ (this.istopheader? arrowsvar.down[1] : arrowsvar.right[1])
+'" class="' + (this.istopheader? arrowsvar.down[0] : arrowsvar.right[0])
+ '" style="border:0;" />'
)
$curobj.hover(
function(e){
var $targetul=$(this).children("ul:eq(0)")
this._offsets={left:$(this).offset().left, top:$(this).offset().top}
var menuleft=this.istopheader? 0 : this._dimensions.w
menuleft=(this._offsets.left+menuleft+this._dimensions.subulw>$(window).width())? (this.istopheader? -this._dimensions.subulw+this._dimensions.w : -this._dimensions.w) : menuleft
$targetul.css({left:menuleft+"px"}).fadeIn(jquerycssmenu.fadesettings.overduration)
},
function(e){
$(this).children("ul:eq(0)").fadeOut(jquerycssmenu.fadesettings.outduration)
}
) //end hover
}) //end $headers.each()
$mainmenu.find("ul").css({display:'none', visibility:'visible'})
}) //end document.ready
}
}
//build menu with ID="myjquerymenu" on page:
jquerycssmenu.buildmenu("myjquerymenu", arrowimages)
这是全部的代码，我想问的是这几行代码的含义：
var arrowimages={down:['downarrowclass', 'arrow-down.gif', 25], right:['rightarrowclass', 'arrow-right.gif']}
var jquerycssmenu={
fadesettings: {overduration: 350, outduration: 100},
buildmenu:function(menuid, arrowsvar){ jquery menu function
[解决办法]
前面定义了json串，剩下的都是基本语法，访问元素，并设置一些事件，比如hover的效果
