所以我有一个弹出窗口，在这个弹出窗口上我有一个 X 按钮用于关闭。它的代码在 html:<a class="close-reveal-modal">×</a>
和 js 中
(function($) {
/*---------------------------
Defaults for Reveal
----------------------------*/
/*---------------------------
Listener for data-reveal-id attributes
----------------------------*/
$('a[data-reveal-id]').live('click', function(e) {
e.preventDefault();
var modalLocation = $(this).attr('data-reveal-id');
$('#'+modalLocation).reveal($(this).data());
});
/*---------------------------
Extend and Execute
---------------------------*/
$.fn.reveal = function(options) {
var defaults = {
animation: 'fadeAndPop', //fade, fadeAndPop, none
animationspeed: 300, //how fast animtions are
closeonbackgroundclick: true, //if you click background will modal close?
dismissmodalclass: 'close-reveal-modal' //the class of a button or element that will close an open modal
};
//Extend dem' options
var options = $.extend({}, defaults, options);
return this.each(function() {
/*---------------------------
Global Variables
---------------------------*/
var modal = $(this),
topMeasure = parseInt(modal.css('top')),
topOffset = modal.height() + topMeasure,
locked = false,
modalBG = $('.reveal-modal-bg');
/*---------------------------
Create Modal BG
----------------------------*/
if(modalBG.length == 0) {
modalBG = $('<div class="reveal-modal-bg" />').insertAfter(modal);
}
/*---------------------------
Open & Close Animations
----------------------------*/
//Entrance Animations
modal.bind('reveal:open', function () {
modalBG.unbind('click.modalEvent');
$('.' + options.dismissmodalclass).unbind('click.modalEvent');
if(!locked) {
lockModal();
if(options.animation == "fadeAndPop") {
modal.css({'top': $(document).scrollTop()-topOffset, 'opacity' : 0, 'visibility' : 'visible'});
modalBG.fadeIn(options.animationspeed/2);
modal.delay(options.animationspeed/2).animate({
"top": $(document).scrollTop()+topMeasure + 'px',
"opacity" : 1
}, options.animationspeed,unlockModal());
}
if(options.animation == "fade") {
modal.css({'opacity' : 0, 'visibility' : 'visible', 'top': $(document).scrollTop()+topMeasure});
modalBG.fadeIn(options.animationspeed/2);
modal.delay(options.animationspeed/2).animate({
"opacity" : 1
}, options.animationspeed,unlockModal());
}
if(options.animation == "none") {
modal.css({'visibility' : 'visible', 'top':$(document).scrollTop()+topMeasure});
modalBG.css({"display":"block"});
unlockModal()
}
}
modal.unbind('reveal:open');
});
//Closing Animation
modal.bind('reveal:close', function () {
if(!locked) {
lockModal();
if(options.animation == "fadeAndPop") {
modalBG.delay(options.animationspeed).fadeOut(options.animationspeed);
modal.animate({
"top": $(document).scrollTop()-topOffset + 'px',
"opacity" : 0
}, options.animationspeed/2, function() {
modal.css({'top':topMeasure, 'opacity' : 1, 'visibility' : 'hidden'});
unlockModal();
});
}
if(options.animation == "fade") {
modalBG.delay(options.animationspeed).fadeOut(options.animationspeed);
modal.animate({
"opacity" : 0
}, options.animationspeed, function() {
modal.css({'opacity' : 1, 'visibility' : 'hidden', 'top' : topMeasure});
unlockModal();
});
}
if(options.animation == "none") {
modal.css({'visibility' : 'hidden', 'top' : topMeasure});
modalBG.css({'display' : 'none'});
}
}
modal.unbind('reveal:close');
});
/*---------------------------
Open and add Closing Listeners
----------------------------*/
//Open Modal Immediately
modal.trigger('reveal:open')
//Close Modal Listeners
var closeButton = $('.' + options.dismissmodalclass).bind('click.modalEvent', function () {
modal.trigger('reveal:close')
});
if(options.closeonbackgroundclick) {
modalBG.css({"cursor":"pointer"})
modalBG.bind('click.modalEvent', function () {
modal.trigger('reveal:close')
});
}
$('body').keyup(function(e) {
if(e.which===27){ modal.trigger('reveal:close'); } // 27 is the keycode for the Escape key
});
/*---------------------------
Animations Locks
----------------------------*/
function unlockModal() {
locked = false;
}
function lockModal() {
locked = true;
}
});//each call
}//orbit plugin call
})(jQuery);

现在 X 按钮始终位于顶部。如何更改脚本以使关闭按钮随页面向下滚动？我需要帮助，因为我对 javascript 知之甚少。有什么办法可以改变，所以弹出窗口总是在关闭它并重新打开后从头开始，而不是从你在关闭它之前阅读的内容开始？
