Wordpress supports custom URL rewrites for search engine friendly URLs, but the fact is they can be a real pain in the ass for WP plugin authors. As is evidenced by the plethora of confused posts out there desperately seeking help with add_rewrite_rule() and add_rewrite_tag(), slapping a few new rules and custom querystring variables in your plugin’s functions.php just doesn’t always cut it. Custom URLs for Wordpress PluginsTake the following scenario: you have a custom plugin for displaying pro ...

I was reading Steve Souder’s blog post on loading scripts without blocking in which he notes that dynamically creating a <script> element and assigning its src attribute leads to a download that doesn’t block other downloads or page processes. His post is missing an example of how to do this, so I thought I’d pick up from there. I think most developers tend to use JavaScript libraries for such behavior (the YUI Get utility comes to mind) but a discussion of the underlying technique is s ...

http://blog.csdn.net/zmyde2010/article/details/6863717有时候需要在显示UI的时候不中断原来的Activity比如在播放视频时或者玩游戏时，需要显示某个菜单(可以是系统提示，或类似于TV菜单)显然用Activity来做是不行的，因为新Activity启动的时候会把原来的Activity pause掉怎么做呢，可以参考系统电量提示窗口或statusbar那样在service中启动窗口新窗口将会出现在UI最上层，但不会中断原来的Activity效果图，一个是播视频中，一个是玩游戏中:看一下WindowManager.LayoutParams的两个属性:intTYPE_SYSTEM_ALERT        Window type: system window, such as low power alert.intTYPE_SYSTEM_OVERLAYWindow&nb ...

Chrome下执行如下代码：注意，这个时候obj的constructor已经不再是创建它的函数，但是修改构造函数的prototype的contructor并不会影响构造函数所产生的对象！这里仍然会调用原来定义的MyClass进行构造，而不会调用新的MyClass.prototype.constructor进行构造。更多烧脑筋的constructor例子请 参考：Constructors considered mildly confusing (如果连接无法打开，可向作者索要pdf文档)这里仅摘录两段 instanceof 例子：function MyConstructor() {}MyConstructor.prototype = {};var myobject = new MyConstructor();myobject instanceof MyConstructor // true  ...

function A() { A.prototype = { print: function(){ alert(“print”); } };}var a = new A();a.print(); // will cause exception: Object #<A> has no method ‘print’a = new A(); // new second timea.print(); // ok now  A本身是一个普通对象：   第一次new A() 的时候，先申请一片内存空间，赋予变量a，并将a的[[Prototype]]指向A.prototype（此时还没有print函数） 然后执行constructor，即A函数体，并将A的prototype重设（此时print函数设置完成）   这样第二次new A() 的时候，a的[[Prototype]]指向我们自己设置的那个prototype对象，就可以调用print函数了     参考：Jav ...
