firefox only：TypeError：toggler is undefined

Question

我已经拼凑了一些工作了几年的mootools手风琴代码，但突然间我发现firefox打破了它 - safari，chrome或IE中没有问题。

控制台显示：类型错误：toggler这里未定义：

toggler.setStyle（ '颜色'， '＃666'）;

我想它的东西非常简单，但对于这个新手而言，我不知道是怎么回事？任何帮助？下面完整的代码：

window.addEvent('domready', function() { 
var myAccordion = new Accordion($('accordion'), 'h1.toggler', 'div.element', { 
    display: -1, 
    opacity: true, 
    alwaysHide: true, 
    onActive: function(toggler, element){ 
     toggler.setStyle('color', '#df1a00'); 

     //remove the toggler hover events to clear out its events when it was inactive 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     { 
      //... 
     }); 
    }, 
    onBackground: function(toggler, element){ 
     toggler.setStyle('color', '#666'); 

     //remove the toggler hover events to clear out its events when it was active 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     {this.setStyle('color', '#df1a00'); 

     toggler.addEvent('mouseleave',function() 
     {this.setStyle('color', '#666'); 

     }); 

     }); 
    } 

}); 

变种myAccordion2 =新手风琴（$（ 'accordion2'）， 'h4.toggler'， 'div.element2'，{ 显示：-1， 不透明度：真， alwaysHide ：真， onActive：功能（toggler，元件）{ toggler.setStyle（ '颜色'， '＃df1a00'）;

 //remove the toggler hover events to clear out its events when it was inactive 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     { 
      //... 
     }); 
    }, 
    onBackground: function(toggler, element){ 
     toggler.setStyle('color', '#666'); 

     //remove the toggler hover events to clear out its events when it was active 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     {this.setStyle('color', '#df1a00'); 

     toggler.addEvent('mouseleave',function() 
     {this.setStyle('color', '#666'); 

     }); 

     }); 
    } 

}); 

var myAccordion = new Accordion($('accordion3'), 'h5.toggler', 'div.element3', { 
    display: -1, 
    opacity: true, 
    alwaysHide: true, 
    onActive: function(toggler, element){ 
     toggler.setStyle('color', '#df1a00'); 

     //remove the toggler hover events to clear out its events when it was inactive 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     { 
      //... 
     }); 
    }, 
    onBackground: function(toggler, element){ 
     toggler.setStyle('color', '#666'); 

     //remove the toggler hover events to clear out its events when it was active 
     toggler.removeEvents('mouseenter'); 
     toggler.removeEvents('mouseleave'); 

     //then add your events again 
     toggler.addEvent('mouseenter',function() 
     {this.setStyle('color', '#df1a00'); 

     toggler.addEvent('mouseleave',function() 
     {this.setStyle('color', '#666'); 

     }); 

     }); 
    } 

}); 

}）;

我看到你正在使用mootools 1.2 mootools最近发布了一个修复1.2导致Firefox的错误，因为新的firefox和mootools与String.concat相撞。

你可以看到一个关于它的Blog Post。 无论如何尝试更新到新的1.2版本，看看它是否解决了问题
