我已经安装了一个jQuery滚动插件，基本上只是让滚动看起来更好，问题是我有一个函数会重新加载页面的大部分（必须在程序中完成）和div的滚动是其中的一部分。
.load：
$('.show_page').load('events.php');
我知道：
$(document).on(...,...,function(e){
战术，但脚本很长，为此复杂，滚动插件的主要控制功能（我认为）就是这部分（在文档加载中）：
scroll_bar = $('.cndr_sidebar_inner').jScrollPane(
{
mouseWheelSpeed: 30,
autoReinitialise: true,
maintainPosition: false,
animateScroll:true
}).data('jsp');
然后有这部分（外侧文档加载）：
(function (factory) {
if ( typeof define === 'function' && define.amd ) {
// AMD. Register as an anonymous module.
define(['jquery'], factory);
} else if (typeof exports === 'object') {
// Node/CommonJS style for Browserify
module.exports = factory;
} else {
// Browser globals
factory(jQuery);
}
}(function ($) {
var toFix = ['wheel', 'mousewheel', 'DOMMouseScroll', 'MozMousePixelScroll'];
var toBind = 'onwheel' in document || document.documentMode >= 9 ? ['wheel'] : ['mousewheel', 'DomMouseScroll', 'MozMousePixelScroll'];
var lowestDelta, lowestDeltaXY;
if ( $.event.fixHooks ) {
for ( var i = toFix.length; i; ) {
$.event.fixHooks[ toFix[--i] ] = $.event.mouseHooks;
}
}
$.event.special.mousewheel = {
setup: function() {
if ( this.addEventListener ) {
for ( var i = toBind.length; i; ) {
this.addEventListener( toBind[--i], handler, false );
}
} else {
this.onmousewheel = handler;
}
},
teardown: function() {
if ( this.removeEventListener ) {
for ( var i = toBind.length; i; ) {
this.removeEventListener( toBind[--i], handler, false );
}
} else {
this.onmousewheel = null;
}
}
};
$.fn.extend({
mousewheel: function(fn) {
return fn ? this.bind("mousewheel", fn) : this.trigger("mousewheel");
},
unmousewheel: function(fn) {
return this.unbind("mousewheel", fn);
}
});
function handler(event) {
var orgEvent = event || window.event,
args = [].slice.call(arguments, 1),
delta = 0,
deltaX = 0,
deltaY = 0,
absDelta = 0,
absDeltaXY = 0,
fn;
event = $.event.fix(orgEvent);
event.type = "mousewheel";
// Old school scrollwheel delta
if ( orgEvent.wheelDelta ) { delta = orgEvent.wheelDelta; }
if ( orgEvent.detail ) { delta = orgEvent.detail * -1; }
// New school wheel delta (wheel event)
if ( orgEvent.deltaY ) {
deltaY = orgEvent.deltaY * -1;
delta = deltaY;
}
if ( orgEvent.deltaX ) {
deltaX = orgEvent.deltaX;
delta = deltaX * -1;
}
// Webkit
if ( orgEvent.wheelDeltaY !== undefined ) { deltaY = orgEvent.wheelDeltaY; }
if ( orgEvent.wheelDeltaX !== undefined ) { deltaX = orgEvent.wheelDeltaX * -1; }
// Look for lowest delta to normalize the delta values
absDelta = Math.abs(delta);
if ( !lowestDelta || absDelta < lowestDelta ) { lowestDelta = absDelta; }
absDeltaXY = Math.max(Math.abs(deltaY), Math.abs(deltaX));
if ( !lowestDeltaXY || absDeltaXY < lowestDeltaXY ) { lowestDeltaXY = absDeltaXY; }
// Get a whole value for the deltas
fn = delta > 0 ? 'floor' : 'ceil';
delta = Math[fn](delta / lowestDelta);
deltaX = Math[fn](deltaX / lowestDeltaXY);
deltaY = Math[fn](deltaY / lowestDeltaXY);
// Add event and delta to the front of the arguments
args.unshift(event, delta, deltaX, deltaY);
return ($.event.dispatch || $.event.handle).apply(this, args);
}
}));
最后是核心编程（也是doc加载）：
