javascript 判断IE6/7/8

#无框架支持 var isIE = !! window.ActiveXObject; var isIE6 = isIE && !window.XMLHttpRequest; var isIE8 = isIE && !! document.documentMode && (document.documentMode == 8); var isIE7 = isIE && !isIE6 && !isIE8;

IE下使用filter实现纯色背景半透明

IE滤镜采用AARRGGBB（16进制）进行排列，AA位值也为 00-FF，也就是说10进制需要转成16进制 计算规则 10进制值*256/100然后再转16进制，就是说如果设置0.4的透明度40*256/100 = 102.4转16进制为66

  .rgba .test{ 
    background:rgba(255,255,255,.4); 
    background:none\9; 
    filter:progid:DXImageTransform.Microsoft.Gradient(startColorStr=#66FFFFFF,endColorStr=#66FFFFFF);
  }

我们将详细讲解一下各种类型的函数是如何影响上下文的变量对象以及每个函数的作用域链都包含什么。

#EcmaScript function ##概要 In this article we will talk about one of the general ECMAScript objects — about functions. In particular, we will go through various types of functions, will define how each type influences variables object of a context and what is contained in the scope chain of each function. We will answer the frequently asked questions such as: “is there any difference (and if there are, what are they?) between functions created as follows:
在这一章节中，我们来探讨下ECMAScript中一个很重要的对象-函数。我们将详细讲解一下各种类型的函数是如何影响上下文的变量对象以及每个函数的作用域链都包含什么，我们将回答诸如像下面这样的问题：下面声明的函数有什么区别么？（如果有，区别是什么）。

var foo = function () {
  ...
};

from functions defined in a “habitual” way?:

JSONP

利用Script标签可以跨域请求
返回的script中：my_callback({['some string 1', 'some data', 'whatever data']});
已定义好的函数：my_callback(){}
