我在网站上使用的是jquery幻灯片菜单,如下所示:
http://www.dynamicdrive.com/style/csslibrary/item/jquery_multi_level_css_menu_2/
然后,当我开始更新我的网站时,我看到了:
http://osvaldas.info/drop-down-navigation-responsive-and-touch-friendly/tag/touch
在移动设备上很不错,但只有一个级别的深度。
我试图将它们合并在一起,但是我不能。有可能做到吗?如果可以,怎么办?
//jqueryslidemenu.js
//Specify full URL to down and right arrow images (23 is padding-right to add to top level LIswith drop downs):
var arrowimages={down:['downarrowclass', 'down.gif', 23], right:['rightarrowclass', 'right.gif']}
var jqueryslidemenu={
animateduration: { over: 200, out: 100 }, //duration of slide in/ out animation, in milliseconds
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>$(window).width())? (this.istopheader? -this._dimensions.subulw+this._dimensions.w : -this._dimensions.w) : menuleft
if ($targetul.queue().length<=1) //if 1 or less queued animations
$targetul.css({left:menuleft+"px", width:this._dimensions.subulw+'px'}).slideDown(jqueryslidemenu.animateduration.over)
},
function(e){
var $targetul=$(this).children("ul:eq(0)")
$targetul.slideUp(jqueryslidemenu.animateduration.out)
}
) //end hover
$curobj.click(function(){
$(this).children("ul:eq(0)").hide()
})
}) //end $headers.each()
$mainmenu.find("ul").css({display:'none', visibility:'visible'})
}) //end document.ready
}
}
//build menu with ID="myslidemenu" on page:
jqueryslidemenu.buildmenu("myslidemenu", arrowimages)
我想将此代码与下面的代码合并。我尝试过,但无法成功。我应该在哪里添加它?
// Doubletaptogo.js
;(function ($, window, document, undefined) {
$.fn.doubleTapToGo = function (params) {
if (!('ontouchstart' in window) &&
!navigator.msMaxTouchPoints &&
!navigator.userAgent.toLowerCase().match(/windows phone os 7/i)) return false;
this.each(function () {
var curItem = false;
$(this).on('click', function (e) {
var item = $(this);
if (item[0] != curItem[0]) {
e.preventDefault();
curItem = item;
}
});
$(document).on('click touchstart MSPointerDown', function (e) {
var resetItem = true,
parents = $(e.target).parents();
for (var i = 0; i < parents.length; i++)
if (parents[i] == curItem[0])
resetItem = false;
if (resetItem)
curItem = false;
});
});
return this;
};
})(jQuery, window, document);
$(function () {
$('#myslidemenu li:has(ul)').doubleTapToGo();
});
谢谢
最佳答案
我要做的是在第一次单击时注册一个计时器,将该变量保存在插件范围内,然后再次访问它以确定是否已经经过了足够的时间将其确定为双击。我认为标准双击是750毫秒。
或者我相信jQuery具有内置的.dblclick()
(可能仅在使用click事件的桌面上有效)。
我在网上找到了以下代码片段:
(function($) {
$.fn.doubleTap = function(doubleTapCallback) {
return this.each(function(){
var elm = this;
var lastTap = 0;
$(elm).bind('vmousedown', function (e) {
var now = (new Date()).valueOf();
var diff = (now - lastTap);
lastTap = now ;
if (diff < 250) {
if($.isFunction( doubleTapCallback ))
{
doubleTapCallback.call(elm);
}
}
});
});
}
})(jQuery);
关于javascript - 双击Jquery滑动菜单即可,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/22483618/
