Question

下面的JS代码 IE提示：消息: 对象不支持此属性或方法 行: 7 字符: 6 代码: 0 怎么解决

Glider = Class.create();
Object.extend(Object.extend(Glider.prototype, Abstract.prototype), {
initialize: function(wrapper,options){
this.scrolling = false;
this.wrapper = $(wrapper);
this.scroller = this.wrapper.down('div.scroller');
this.section = this.wrapper.getElementsBySelector('div.section');
this.options = Object.extend({ duration: 1.0, frequency: 3 }, options || {});

this.sections.each( function(section, index) {
section._index = index;
});

this.events = {
click: this.click.bind(this)
};

this.addObservers();
if(this.options.initialSection) this.moveTo(this.options.initialSection, this.scroller, { duration:this.options.duration }); // initialSection should be the id of the section you want to show up on load
if(this.options.autoGlide) this.start();
},

addObservers: function() {
var controls = this.wrapper.getElementsBySelector('div.controls a');
controls.invoke('observe', 'click', this.events.click);
},

click: function(event) {
this.stop();
var element = Event.findElement(event, 'a');
if (this.scrolling) this.scrolling.cancel();

this.moveTo(element.href.split("#")[1], this.scroller, { duration:this.options.duration });
Event.stop(event);
},

moveTo: function(element, container, options){
this.current = $(element);

Position.prepare();
var containerOffset = Position.cumulativeOffset(container),
elementOffset = Position.cumulativeOffset($(element));

this.scrolling = new Effect.SmoothScroll(container,
{duration:options.duration, x:(elementOffset[0]-containerOffset[0]), y:(elementOffset[1]-containerOffset[1])});
return false;
},

next: function(){
if (this.current) {
var currentIndex = this.current._index;
var nextIndex = (this.sections.length - 1 == currentIndex) ? 0 : currentIndex + 1;
} else var nextIndex = 1;

this.moveTo(this.sections[nextIndex], this.scroller, {
duration: this.options.duration
});
},
我用的是 IE8

Answer 1

this.section = this.wrapper.getElementsBySelector('div.section');
不支持此属性或方法调用。

Answer 2

html代码也贴出来吗
