用ExtJS开发将近一年了，也遇到了很多奇怪的问题，印象最深的要算是ExtJS在ie中显示的问题了。由于开发过程中大多用chrome来调试，很少在ie中调试（现在两者都要兼顾），导致最后在ie中页面不能正常加载，当时那个囧啊，看到ie报的错，我都想哭，连出错的堆栈信息都没有（这一点，ie做的真不好），无从下手啊。尝试过N多方法，最后发现导致出现这种问题的原因（90%以上的可能性）是js的数组中多了一个英文的逗号','，而这种在chrome和火狐中是没有问题的，如下面的代码所示：

复制代码 代码如下:

var win = Ext.create('Ext.window.Window',{
//此处省略若干代码
//........
items:[
{
title:'hello',
width:100,
height:100
},{
title:'world',
width:100,
height:100
},{
title:'foo',
width:100,
height:100
},//注意这里的英文逗号，在chrome和火狐中不会报错
]
//此处省略若干代码
//........
})

这是浏览器对数组处理的一个差异。大家写代码的时候要注意一下，如果有类似的问题可以试着找找看，也许就能够解决了，我遇见过三次，都是这个问题。（完）^_^
