2. 据说 table innerHTML 是只读的。
 
3. window.location.href = "";

关于代码压缩。
 
1. 压缩工具分类之。
 
一类：文件压缩。 Gzip。压缩几个文件成一个 gz 包。下载代码时，可提高速度。》官方网。 这个很早就有了，并且现在还在用着~
 
另一类：去掉文件注释空白等。 如 JSMin，YUI Compressor ，Google Closure Compiler。可能还有 Dojo Compressor 等等。

大概从此后，我会习惯用选择器这个东西。其实我觉得这个还是很好用滴。借此学习并总结下选择器。
 
其实最早有选择器的概念是因为 JQuery。偶尔码了两眼，有个简单的认识。记得去年入职面试还被问到关于选择器的问题，但后来用的很少，前段时间因为 id 的问题搞得头大了，便捡起选择器开始玩。这次又将选择器提了出来。正好想一下什么时候更好的使用什么样的选择器吧。

1.光标不变 
直接obj.focus()，光标会返回之前的位置，即位置不变

2.光标在最前
var r = document.body.createTextRange();
r.collapse(true);
r.select();

3.光标在最后
var r = document.body.c]]>https://blog.youkuaiyun.com/hanyuxinting/article/details/6339378https://blog.youkuaiyun.com/hanyuxinting/article/details/6339378hanyuxintingThu, 21 Apr 2011 18:07:00 +0800今天上代码的时候遇到了一个问题，代码做了压缩和混淆后，某变量undefined。
 
跟踪才发现原来某变量定义在 eval 中。导致混淆时将在其中定义的变量漏掉，导致后续变量 undefined。
 
对于eval，学习过很多次，每次学了每次忘，总是不知道它是干什么的。。只记得曾经把一陀螺数据（字符串）转化为了一个对象。今天栽它头上，郁闷！
 
1.
 

alert(eval('{a:2}')); // ]]>https://blog.youkuaiyun.com/hanyuxinting/article/details/6332825https://blog.youkuaiyun.com/hanyuxinting/article/details/6332825hanyuxintingTue, 19 Apr 2011 10:22:00 +08001 。
var herp="one"; 
{ 
    var herp="two"; 
} 
alert(herp); // two
 
理解块级作用域。对于JS，没有块级作用域~~~~区别与其他强类型语言。
 
 
2 。
另外，局部变量在整个函数内都是有定义的，即整个函数体中都隐藏了同名的全局变量。故：
 
var scope = "gl]]>https://blog.youkuaiyun.com/hanyuxinting/article/details/6330436https://blog.youkuaiyun.com/hanyuxinting/article/details/6330436hanyuxintingMon, 18 Apr 2011 10:02:00 +0800var test = 12;
var test1 = 123;
var b = test || test1;
alert(b);
 
我居然被此困住。谨记。]]>https://blog.youkuaiyun.com/hanyuxinting/article/details/6321303https://blog.youkuaiyun.com/hanyuxinting/article/details/6321303hanyuxintingWed, 13 Apr 2011 18:43:00 +08001. 使用crossdomain.xml让Flash可以跨域传输数据

目的：领会JS实现XPCOM的思想。
    
JS实现的xpcom需要和xpt放在一个文件夹下，即components文件夹下。
（同理，c++实现的xpcom 即 dll文件 需要和xpt放在同一个文件夹下，也是components文件夹下）。
