Javascritpt: Get Your Class Object Name

Here's the script that retrieve your Javascript object class name:

<script>
function getObjectClass(obj){
if (typeof obj != "object" || obj === null) return false;
else return /(\w+)\(/.exec(obj.constructor.toString())[1];}

function myObj(){
this.shout=function(mywords){
alert(mywords);
}
}
var x=new myObj();
x.shout('good day');

var myClassname=getObjectClass(x);
x.shout('My JS Class Name is '+ myClassname);
x.shout('My Object Constructor:' + x.constructor.toString());

外行人吃燕窩，內行人吃白木耳

『外行人吃燕窩，內行人吃白木耳』

by 茶陶音刀 on Thursday, April 21, 2011 at 7:54pm

其實『膠質』和『骨質』在人體內就好比房子的『水泥』和『磚塊』
通常一些老化現象都是膠質缺乏才會引發。

白木耳是養顏秘方，卻鮮少人知道。

人隨著年齡的增長，皮膚內膠質(膠原蛋白)
會漸漸流失，然後皮膚漸漸鬆弛，失去彈性。

至於如何補充膠質(膠原蛋白)，用擦的是沒用的，因為膠原蛋白是大分子，用擦的只能到表皮層增加皮膚保濕度，無法補充到真皮層失去彈性的肌膚。

所以要用吃的補充膠質(膠原蛋白)像是豬腳,雞腳,牛筋,白木耳,燕窩都是富含膠質的食物，如果以現在女性在乎身材為前題，白木耳絕對是補充膠質的最佳食物首選。

白木耳富含的植物膠質絕不輸燕窩，之前是聽人家說：『有錢人吃燕窩，沒錢人吃白木耳』。

但最近有本雜誌說，辜家二少爺辜仲瑩也是
早上吃一碗，煮爛不加糖的白木耳，保養皮膚。

所以應該改成：『外行人吃燕窩，內行人吃白木耳』。

至於如何煮白木耳：

1.去超市買盒裝 "黃"木耳，(! 千萬不要買純白木耳 ,因為純白木耳煮不爛)。

3.倒掉前兩次泡黃木耳的水,因為有些腥味。

4.然後將黃木耳加水放進果汁機打爛。

5.再將打爛的黃木耳放進鍋裡煮約一個小時。(水加多少自己斟酌)
加蓮子糖水，單加糖水，加蜂蜜，加果糖，或冰糖! ...)

一天吃一碗，照上面方法，用果汁機打爛黃木耳去煮，會發現：

吃起來根本跟外面賣的即食燕窩一模一樣。
所以愛美的人，愛美不假手他人，自己來煮白木耳養顏吧!

白木耳是一種營養豐富的滋補品，被譽為[菌中之冠]，有滋陰補腎，潤肺生津，強心健腦，提神補氣等功能，對陰虛火旺不受參茸等溫熱滋補的病人是一種良好的補品。
因其含有天然特性膠質，加上它的滋陰作用，女性長期服用可以潤膚，並有祛除臉部黃褐斑、雀斑的功效。

黑木耳味道鮮美，含有豐富的營養素，可與動物性食物相媲美，被譽為[素中之葷]。
黑木耳含鐵量極高，是豬肝的5倍，為天然的補血佳品，適宜女性常吃，能養血駐顏烏發、防治缺鐵性貧血。
黑木耳中所含膠質具有極強的吸附作用，可以把殘留在人體消化系統內的雜質吸附集中起來排出體外，可以說是'身體清道夫。
黑木耳對於中老年人有特別的好處，其中含有的磷脂類化合物，可以幫助延緩記憶力減退及減少老年痴呆症的發生﹔豐富的纖維素能促進胃腸蠕動，減少食物中脂肪的吸收，起到防止肥胖和減肥作用，對冠心病、動脈硬化、心腦血管病頗為有益。
從營養上來說，黑木耳更勝一籌，這也契合了最近吃黑色食品的風尚。
但吃黑木耳貴在堅持，最好每天都有一道木耳菜，不論涼拌或者炒食都不錯!

Changing HTML Form Element Type with Javascript

I was looking for a solution that allow me to dynamically change the form element's type before a submission.
With following example, once the select box has been changed to a text box, you can assign any value you like to it(of course,alternative way is to create new Option with your desired value, and set the selectedIndex ).
Here's javascript function:

<form method='post'>
<select name='myselect'>
<option value='1'>Option1</option>
<option value='2'>Option2</option>
</select>
<input type='button' onclick='changeInputType(this.form.myselect, "text");'>
</form>
<script>
function changeInputType(oldObject, oType) {
var newObject = document.createElement('input');
newObject.type = oType;
if(oldObject.size) newObject.size = oldObject.size;
if(oldObject.value) newObject.value = oldObject.value;
if(oldObject.name) newObject.name = oldObject.name;
if(oldObject.id) newObject.id = oldObject.id;
if(oldObject.className) newObject.className = oldObject.className;
oldObject.parentNode.replaceChild(newObject,oldObject);
return newObject;
}
</script>

The javascript was copied from this website

JQuery Dialog Remove Form Elements

I have used JQuery UI Dialog box as a container to hold some of my form elements, and show it after a button click. Somehow, all these elements that covered under the Jquery Dialog DIV failed to POST back to the server.
JQuery Dialog seems removed the form element out from the original dom structure, thus causing the problem. The solution will be
1) Add an additional DIV or SPAN before your closing FORM tag(give it an ID),
2) Before the form submit, append the Dialog DIV back to the above created DIV or SPAN

Here's the sample code:

<!DOCTYPE html>
<html lang="en">
<?php
if($_POST['username']) echo "<br/> Username is " . $_POST['username'];
if($_POST['outerfield']) echo "<br/> Username is " . $_POST['outerfield'];
?>
<head>
<meta charset="utf-8">
<title>jQuery demo</title>
</head>
<body>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css" type="text/css" media="screen">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.11/jquery-ui.min.js"></script>
<script>
//google.load("jquery", "1.5.1");
//google.load("jqueryui", "1.8.11");
</script>
<form id="form1" method='post'>
<input type="button" class="button" value="go dialog" onclick="GoDialog()" />
<input type='button' class='button' value='Check Value1' onclick='checkvalue("outerfield");'>
<input type='button' class='button' value='Check Value2' onclick='checkvalue("username");'>
<input type='button' class='button' value='Put It Back' onclick='putitback("username");'>
<br/> OuterField <input type='text' name='outerfield' size='20'>
<div class="dlg" id="msgDlg" style='display:none;'>
<br/>Name: <input type="text" name='username' />
<br/><input type="button" class="button" value="OK" onclick="$('#msgDlg').dialog('close');" />
</div>

<div id="beforesubmit" style="display:none"></div>

$("#form1").submit(function() {

$("#msgDlg").prependTo("#beforesubmit");

});

分享：般若波罗蜜多心经

缘起，小时候大概是初中一二左右，每星期都有两三天会梦见自己半梦半醒之中和灵体有所接触，甚至到来抚摸我的额头，恐怖到极点。

在机缘巧合之下，和般若波罗蜜多心经结下了缘，除了背上了心经，还在房间里贴上了心经。说也奇怪，自从房间里贴上了心经后，那些灵体有关的梦就结束了。

最记得一次的怪遇是有一次我在谁梦中被灵体骚扰，弯起了我的手往自己的喉咙捉去，结果在最紧张的时刻，我心里只念了一句“观自在菩萨”，整个世界突然什么也没了，我的手也松了下来，心经实在是太不可思议了。如果你有缘看到这篇文章，希望你也赶快的背诵心经，好好的感受心经的胜殊。记得哦，背诵心经会开智慧的哦！

般若波罗蜜多心经

唐三藏法师玄奘译

观自在菩萨行深般若波罗蜜多时
照见五蕴皆空度一切苦厄

舍利子
色不异空空不异色
色即是空空即是色
受想行识亦复如是

舍利子
是诸法空相不生不灭
不垢不净不增不减
是故空中无色无受想行识
无眼耳鼻舌身意无色声香味触法
无眼界乃至无意识界
无无明亦无无明尽
乃至无老死亦无老死尽
无苦集灭道无智亦无得以无所得故

菩提萨陲依般若波罗蜜多故
心无　碍无　碍故无有恐怖
远离颠倒梦想究竟涅盘

三世诸佛依般若波罗蜜多故
得阿耨多罗三藐三菩提

故知般若波罗蜜多
是大神咒是大明咒是无上咒
是无等等咒能除一切苦真实不虚

故说般若波罗蜜多咒
即说咒曰揭谛揭谛波罗揭谛
波罗僧揭谛菩提娑婆诃
般若波罗密多心经

青木瓜泡茶痛風不見了治療尿酸效果更佳

Papaya tea for gout

青木瓜泡茶痛風不見了

這是真的有效果，用一般綠茶茶葉泡也可以，我

堂哥吃了有效，我也教有痛風的朋友喝(他腳趾關

節已變形)，一週後就有很明顯的改善，兩週後就

正常了，事隔有近三年了，沒聽他說有痛過，不

過他怕復發，每月都會喝1~3次。

This is a really effective, just mix green papaya cubes to the ordinary green tea, my cousin brother tried and found it very effective. I have also shared with a friend with gout to try this (his "toe joints" started to deform), after a week of drinking this formula there is significant improvement, after two weeks the toe joints heal and revert to normal state. It is almost th! ree years now, the joint pain is gone, but he maintain the intake between 1-3 times monthly to avoid relapse.

其他的朋友喝了都有解決多年痛風的困擾，沒事也可喝，還不錯。

Other friends suffering from years of gout problem have also recovered. It is good for all, even those without gout.

好方法喔~~趕快告訴需要的人吧!!!!

Good formula! Do share with the people in need!

中國藥學院--- 賴教授改良新方式:

An improved sequence by Professor Lai from the China School of Pharmacy :

將青木瓜切成丁放入水中煮沸後才放入茶葉，泡茶過程和一般茶葉相同。

據實際臨床經驗效果更佳，而且治療尿酸效果更佳(須常期喝)

Cut green papaya into small cubes, place into the water, brin! g to boil, then add green tea leaves, similar to the tea-making process. Clinical tests show that this brings better effects for treatment of gout, subject to frequent drinking of this formula.

青木瓜泡茶

台南縣仁德鄉後壁村長劉結慶患胃痛多年，把青木瓜當做茶壺泡茶喝，一個月後竟治癒宿疾，家人尿酸過多喝木瓜泡茶也不藥而癒，劉村長因而種了許多木瓜，送給有病的親友鄉親。

Mr Liu Qing, Chief of the Rende Town in Tainan, was suffering for years from severe stomach pain around the posterior wall of stomach. He used green papaya as a tea pot to prepare the family tea daily, after a month his chronic disease condition was much improved. His family members with high uric acid were also healed by the same papaya tea. For this Mr Liu planted a lot of papaya to sha! re with relatives and friends with similar sickness.

劉村長說，青木瓜最好選擇果實肥短，容量比較大，將木瓜頂部切開，挖出木瓜內的種籽，再開一個小缺口方便倒茶水，8 F一邊開個小洞透氣，放入茶葉、倒進沸水後蓋回木瓜頂部，並以牙籤固定，泡茶過程和一般茶葉相同。

According to Mr Liu, in selection of the Green Papaya as tea pot, pick those whose shape are fat and short, with larger capacity. Cut off the top part of the papaya, clear away the seeds, open a small hole at the upper side wall to facilitate pouring of tea. Create a small ventilation hole at top cover, put in the tea leaves, pour in boiling water, place the top cover back to papaya, you may use the toothpicks to secure the top cover. Similar to normal process of preparing tea.

劉村長表示，茶葉使用一般品質的烏龍茶即可，味道不錯，他當做茶水喝了一個月，困擾多年無法治癒的胃痛居然不藥而癒，自己也感到驚訝，他把木瓜茶葉拿給在醫學中心任職的友人檢驗，證實木瓜酵素有益健康，現在只要果園木瓜有適合的果實，就拿來與親友分享。

Liu like to use Oolong tea as the taste is good. He was pleasantly surprised that the stomach pains he suffered for many years was healed after a month of drinking tea from the green papaya pot, without taking any other medication. He passed some green papaya leaves to a friend who worked at a Medical Center to test and analyse the content. The tests confirmed that healthy the enzyme present in papaya is beneficial to human health. Now as papaya in Mr Liu's orchard is yeilding suitable size fruit, he would share the fruits with family and friends.

種植木瓜多年的農民徐福昌說，本地民眾所指的青木瓜，就是還未成熟! 、果皮仍呈青綠色的木瓜，一般木瓜要四個月左右才會成熟，但成熟後就沒有療效，青木瓜大約在三個月大左右採收，這時果實較，果實內的「木瓜奶」含有木瓜酵素、木瓜等有B健康成份，不但可泡茶喝，還可以切塊連同排骨熬，或切細絲加蒜頭炒，都非常可口，對人體也沒有不良影響。

Xu Fuchang, an experienced papaya farmers, the green papaya refers to papaya that is not ripe, where the skin is still green in colour. Generally, the papaya takes about four months to fully mature and ripe, but there healing effect would be lost after it is fully ripe. Green Papaya should be harvested when the papaya is approximately three months old, when the fruit is still firm, and the "papaya milk" contains high papaya enzyme and other healthy ingredients. Not only the green papaya can be used in tea drinking, you may also cut them into cubes, and boil with the ribs, or even slicing the green papaya into fine long pieces and fried with garlic, very tasty, and no adverse effects on ! the human body.

Process Forking with PHP

Posted March 4th, 2004 in PHP

Unix supports the process of forking which allows a parent process to spawn a subprocess and continue running both processes concurrently. It is possible to do this in PHP using the PHP Process Control Functions. Note that you should never attempt to use these process control forking functions when using a webserver; you shuld only fork applications when using the PHP command line client.

Before you can use the PHP process control functions you must compile the PCNTL extensions into PHP using the --enable-pcntl configure option (ie ./configure --enable-pcntl along with all the other configuration options you would like to compile into the PHP binary). No additional libraries need to be pre-installed. Note that these process control extensions will not work on non-Unix platforms (ie Microsoft Windows).

Basic Forking Example

A very basic and commonly used example for forking a process in PHP is as follows:

$pid = pcntl_fork();

if($pid) {
  // parent process runs what is here
  print "parent\n";
}
else {
  // child process runs what is here
  print "child\n";
}

Running this will output the following:

child
parent

Child process is a copy of the parent process

What actually happens when you call the pcntl_fork() function is that a child process is spawned which is exactly the same as the parent process and continues processing from the line below the function call. All variables and objects etc are copied into the child process as-is but these are new copies which belong to the new process. Modifying them in the child process does not affect the values in the parent (or any other forked) process.

The parent process will have a value assigned to $pid whereas the child process will not, hence the if test. Note that in the above example, both processes would continue running whatever code is after the if statement, something which is rarely mentioned in examples of PHP process forking on the web.

To illustrate this, we'll modify the example above slightly to add additional output as follows:

$pid = pcntl_fork();

print "start\n";

if($pid) {
  // parent process runs what is here
  print "parent\n";
}
else {
  // child process runs what is here
  print "child\n";
}

print "end\n";

Running this will display the following:

start
child
end
start
parent
end

Making the parent process wait until the child has finished

So ideally you want to let either the child or parent continue processing the rest of the script and make the other process exit after the process is forked. If you exit from the parent process, however, you'll end up with "zombie" processes running which do not belong to any process. Therefore the parent process needs to wait until all the child processes have finished running before exiting itself. You can do this using the pcntl_waitpid() function, which will cause the parent process to wait until the child process has completed. You can then either just let the parent process exit, or do any tidy up code that is required.

An example of doing this is as follows:

$pid = pcntl_fork();

if($pid) {
  // this is the parent process
  // wait until the child has finished processing then end the script
  pcntl_waitpid($pid, $status, WUNTRACED);
  exit;
}

// the  child process runs its stuff here and then ends

...

The exit call in the parent process ensures that processing stops at that point and the parent does not execute any of the code intended for the child. Another way of doing the same thing without the exit code would be as follows:

$pid = pcntl_fork();

if($pid) {
  // this is the parent process
  // wait until the child has finished processing then end the script
  pcntl_waitpid($pid, $status, WUNTRACED);
}
else {
  // the child process runs its stuff here
}

Exit codes from the child process

You could optionally have an exit call at the end of the child part of the if statement.

The $status parameter passed to pcntl_waitpid() stores the return value from the child process. If the child process returns 0 (ie success) then it will also be zero. On my Linux desktop the value returned as $status would be the value returned from the exit call multipled by 256. So if the child process ended with exit(2) my system returned 512 as the $status value. Whether this is the same across all Unix systems I do not know.

Getting the parent process to wait until the child process has completed is useful for then doing something else based on the return value of the child process as shown in the following example:

$pid = pcntl_fork();

if($pid) {
  // this is the parent process
  // wait until the child has finished processing then end the script
  pcntl_waitpid($pid, $status, WUNTRACED);
  if($status > 0) {
     // an error occurred so do some processing to deal with it
  }
}
else {
  // the child process runs its stuff here
  ...
  if(...successful condition...) {
     exit(0); // this indicates success
  }
   else {
     exit(1); // this indicates failure
  }
}

Forking multiple child processes

This final example illustrates how you could fork several children from the parent process with PHP. The loop runs three times and forks a child process for each loop, storing the child pids into an array. After running the stuff for the child process the child then exits. A second loop runs in the parent after the first to ensure all child processes have finished running before resuming its own process.

Note it is very important in this sort of process that the child explicitly exits in its section of the script, otherwise each child will continue running through the first, and then second, loop.

$pids = array();

for($i = 0; $i < 3; $i++) {

  $pids[$i] = pcntl_fork();

   if(!$pids[$i]) {
     // child process
     ...
     exit();
  }

}

for($i = 0; $i < 3;  $i++) {
  pcntl_waitpid($pids[$i], $status, WUNTRACED);
}

// complete parent processing now all children have finished
...

The PHP manual pages for process control functions can be found at www.php.net/manual/en/ref.pcntl.php. There are a number of user contributed notes for each of the functions which should also help with your understanding of process forking in PHP.
