定義

Function類可以表示開發(fā)者定義的任何函數(shù)，用Function類直接創(chuàng)建函數(shù)的語法如下：

var function_name=new Function(agrument1,agrument2,...,argumentN,function_body);每個argument都是一個參數(shù)，最后一個參數(shù)是函數(shù)主體(要執(zhí)行的代碼)。

示例：

復制代碼 代碼如下:

function sayHi(sName,sMessage){

alert(“Hello ”+sName+“,”+sMessage);

}

還可以如下定義它：

var sayHi=new Function(“sName”,“sMessage”,“alert(”Hello“+sName+”,“+sMessage);”);

注：盡管可用Function構(gòu)造函數(shù)創(chuàng)建函數(shù)，但最好不要使用它，因為用它定義函數(shù)比用傳統(tǒng)方式要慢得多。不過，所有函數(shù)都應(yīng)看作是Function類的實例。

屬性和方法

因為函數(shù)是引用類型，所以它們也有屬性和方法，ECMAScript定義的屬性length聲明了函數(shù)期望的參數(shù)個數(shù)，例如：

復制代碼 代碼如下:

function doAdd(iNum){

alert(iNum+10);

}

function sayHi(){

alert(“Hi”);

}

alert(doAdd.length);//outpus 1

alert(sayHi.length);//outpus 0

Function對象也有與所有對象共享的標準valueOf()方法和toString()方法，這兩個方法返回的都是函數(shù)的源代碼，在調(diào)試時尤其有用。

例如：

復制代碼 代碼如下:

function doAdd(iNum){

alert(iNum+10);

}

alert(doAdd.toString());

這段代碼輸出了doAdd()函數(shù)的文本。

閉包

定義

所謂閉包，是指詞法表示包括不必計算的變量的函數(shù)，也就是說，該函數(shù)能使用函數(shù)外定義的變量。在ECMAScript中使用全局變量是一個簡單的閉包實例。

示例：

復制代碼 代碼如下:

var sMessage=“Hello World”;

function sayHelloWold(){

alert(sMessage);

}

sayHelloWorld();

在一個函數(shù)中定義另一個函數(shù)會使閉包變得更復雜，如：

復制代碼 代碼如下:

var iBaseNum=10;

function addNumbers(iNum1,iNum2){

function doAddtion(){

return iNum1+iNum2+iBaseNum;

}

return doAddtion();

}

這里函數(shù)addNumbers()包括函數(shù)doAddtion()（閉包）。內(nèi)部函數(shù)是個閉包，因為它將獲取外部函數(shù)的參數(shù)iNum1和iNum2以及全局變量iBaseNum的值。addNumbers()的最后一步調(diào)用了內(nèi)部函數(shù)，把兩個參數(shù)和全局變量相加，并返回它們的和。這里要掌握的重要概念是doAddtion()函數(shù)根本不接受參數(shù)，它使用的是從執(zhí)行環(huán)境中獲取的。

可以看到，閉包是ECMAScript中非常強大多用的一部分，可以用于執(zhí)行復雜的計算。就像使用任何高級函數(shù)一樣，在使用閉包時要當心，因為它們可能會變得非常復雜。本文示例代碼

復制代碼 代碼如下:

Length:

valueOf()/toString():

基礎(chǔ)體溫 女性隨時了解自身健康的法寶 2012年09月08日 | 作者: songhoubo | 分類:|

簡介：每個月的天是女性，而不是擔心一天后，有時提前延遲，疼痛痛經(jīng)冷汗淚水流在一起。

尤其是在冬天，裙子，褲子，等等，婦女往往因為愛美，而忽略了溫暖，導致痛經(jīng)加劇，還是有很多女性月經(jīng)將被推遲，等。

溫度不規(guī)則的月經(jīng)周期紊亂，痛經(jīng)閉經(jīng)

>” f=”點擊圖片進入下一頁>> ” d=”Click on image to enter the next page > >”>點擊圖片進入下一頁>>

月經(jīng)不動，周期紊亂，痛經(jīng)，閉經(jīng)等，其實是子宮出現(xiàn)一些不健康的因素，反映了外部。當這些不健康的因素表現(xiàn)為一些癥狀，表明他們已經(jīng)開始對健康產(chǎn)生 了一定的影響。女人都希望盡快知道自己如果沒有健康的因素，以避免對健康的影響，最簡單的方法是測量基礎(chǔ)體溫。準媽媽們不知道基礎(chǔ)體溫可以幫助找到最好的 GET懷孕，但它也可以反映女性功能的變化，有利于發(fā)現(xiàn)，女性的健康問題。女人不應(yīng)該只是希望當寶寶測量基礎(chǔ)體溫，應(yīng)堅持很長一段時間的測量，讓自己有一 個健康快樂的生活。

測量基礎(chǔ)體溫，容易提高健康寶寶

測量基礎(chǔ)體溫可以幫助準媽媽們找到自己的最佳GET懷孕，容易提高健康的寶寶。婦女基礎(chǔ)體溫在月經(jīng)周期目前高溫期和低溫階段兩個階段的變化?；A(chǔ)體 溫高溫相變溫度的低溫階段之前和之后，在3-4天的準媽媽是懷孕的最佳時期。如果基礎(chǔ)體溫不高低溫兩相變化，說沒有排卵，如果缺乏高溫期是12天，黃體元 素分泌不足，更困難的概念。這些將導致雌性不育。同時，懷孕后基礎(chǔ)體溫持續(xù)高溫，如果突然下降，可能是前兆流產(chǎn)。未準媽媽們發(fā)現(xiàn)，這些條件必須及時就醫(yī)。

對比基礎(chǔ)體溫，發(fā)現(xiàn)健康問題，盡快

婦女應(yīng)該堅持很長一段時間測量基礎(chǔ)體溫，相比以前的基礎(chǔ)體溫曲線，及時發(fā)現(xiàn)基礎(chǔ)體溫的異常變化，早在可能的健康問題。女性如果低溫期或http:///基礎(chǔ)體溫是不 是穩(wěn)定的高溫期，日平均氣溫變化大，這可能是因為工作繁忙，疲勞，成都發(fā)票，心情不好的原因。這時候多休息，學會緩解壓力，保持愉快的心情。如果比以往任 何時候整個身體溫度下降，可能是因為子宮寒。子宮寒多的原因，可能是因為冬天穿的夠溫暖，夏天久坐空調(diào)房，吃生冷食物過多或過冷的食品，快速減肥是不是當 地的藥物，這一次，及時關(guān)注生活，調(diào)整飲食，服裝，等等。

觀察基礎(chǔ)體溫快樂的單身漢遲早也會結(jié)婚，幸福地度過更年期

更年期婦女的基礎(chǔ)體溫測量也是非常重要的，觀察基礎(chǔ)體溫的變化可以幫助女性過了更年期的幸福。更年期婦女絕經(jīng)前絕經(jīng)后一個較長的時間，每個女性更年 期開始時間是不同的，持續(xù)時間也不同。陷入衰退的卵巢功能強勁，婦女進入更年期后，雌激素分泌減少，卵泡成熟發(fā)生障礙，甚至不再排卵。在基礎(chǔ)體溫，可用于 高溫期間的表現(xiàn)更短的時間，高低溫溫度差異較小的，即使沒有高低溫兩相變化等觀察基礎(chǔ)體溫變化，就可以知道，無論是作為盡快進入絕經(jīng)期，盡快調(diào)整心態(tài)，準 備好讓一個女性，以滿足新的人生階段。

測量基礎(chǔ)體溫，一定要使用女性專用體溫計。女性專用體溫計和普通的家用溫度計的最大區(qū)別是，它可以顯示2位小數(shù)，因為基礎(chǔ)體溫的溫度變化差異較小，只能顯示2位小數(shù)的溫度計可以準確的測量。同時，它是一種測量口腔溫度的溫度計，因為口腔的溫度更接近真正的人體溫度，因此安全性也很重要，最好選擇電子 體溫計。今天，女性特殊的體溫計不再是傳統(tǒng)的“筆型”，也出現(xiàn)了一些人性化更方便女性專用體溫計。如歐姆龍女性專用體溫計MC – 440，形狀如小化妝盒，它的大屏幕上自動生成基礎(chǔ)體溫變化曲線，讓身體溫度變化一目了然，超強的記憶功能，更方便的比較，60秒預測模型，大大縮短測量 時間，各種人性化的功能，更適合現(xiàn)代忙碌的女性。

The basal body temperature of women to keep abreast of a magic weapon of their own health

September 8, 2012 | Author: songhoubo | Category: white-collar health |

Description: The day of the month is a woman, and not to worry about the day, sometimes ahead of time delay, dysmenorrhea pain cold sweat tears flow together.Especially in winter, skirts, pants, and so women often because of beauty, while ignoring the warm, resulting in dysmenorrhea intensifies, there are still a lot of female menstruation will be postponed, etc..Temperature irregular menstrual cycle disorders, dysmenorrhea, amenorrhea

Menstruation does not move, cycle disorders, dysmenorrhea, amenorrhea, in fact some unhealthy factors uterus, reflects the external.When these unhealthy factors showed some of the symptoms, and that they have certain health.Women want to know as soon as possible of their own if there is no health factors, in order to avoid the impact of health, the easiest way is to measure basal body temperature.Mothers who do not know the basal body temperature can help find the best GET pregnant, but it can also reflect the changes in the function of the female, is conducive to the discovery, women's health issues.The woman should not just hope that when the baby basal body temperature measurement, should adhere to a long period of time measurement, so that they have a healthy and happy life.Measurement of basal body temperature, easy to improve the health of the baby

Measurement of basal body temperature can help mothers who find their own best GET pregnant, easy to improve the health of the baby.Women's basal body temperature changes in the high temperature phase of the menstrual cycle and the low-temperature phase of two phases.Before and after the basal body temperature high-temperature phase transition temperature of the low temperature phase, in the best period of 3-4 days, the expectant mother is pregnant.The basal body temperature is high and low temperature phase change, that there is no ovulation, if the lack of high-temperature period is 12 days, inadequate secretion of luteal elements, the more difficult concepts.These will lead to female infertility.Pregnant basal body temperature sustained high temperatures, if a sudden drop may be a precursor to abortion.Not expectant mothers, these conditions must be timely medical treatment.Contrast basal body temperature found health problems as soon as possible

Women should adhere to a long period of time to measure basal body temperature, compared to the previous basal body temperature curve, to detect abnormal changes in basal body temperature, as early as possible health problems.Women if the period of cold or basal body temperature is not stable high temperature period, the average daily temperature changes, this may be because of busy work, fatigue and mental stress, bad mood reason.This time to rest, learn to relieve stress and maintain a happy mood.Entire body temperature drops, more than ever, it might be cold

because the uterus.Uterine cold winter wear warm enough in summer sedentary air-conditioned rooms, eat too much cold food or cold food, fast weight loss is not a local drug, this time, life concerns in a timely manner, adjusting the diet, clothing, and so on.Observe the basal body temperature and happy man should marry happily through menopause

Menopausal women, basal body temperature measurement is also very important, the observed changes in basal body temperature can help women after menopause happiness.Menopausal women menopause before menopause after a longer time, each female menopause start time, duration.Strong recession ovarian function, women enter menopause, estrogen secretion reduce follicular maturation occurs obstacles, and even longer ovulation.In basal body temperature, can be used for high temperature during the performance of a shorter time, the high cryogenic temperature differences smaller, even in the absence of both high and low temperature phase change observed changes in basal body temperature, you can know whether it is as soon as possible to enter menopause, as soon as possible to adjust mentality, ready for a female, to meet a new stage of life.Measure basal body temperature, be sure to use the women-only thermometer.The women-only thermometer and ordinary household thermometer biggest difference is that it can display two decimal places, because the temperature changes of the basal body temperature differences, can only display two decimal thermometer can accurately measure.The same time, it is a measurement of the oral temperature thermometer, closer to the true body temperature because the temperature of the mouth, so the security is also very important, the best choice electronic thermometer.Today, women's special thermometer is no longer the traditional ”pen type", there have been some humanity more convenient women dedicated thermometer.Such as Omron women dedicated thermometer MC-440, shape, such as a small cosmetic case, it's the big screen on automatic generation of basal body temperature curve, changes in body temperature at a glance, super memory function, more convenient comparison, 60 seconds forecasting model greatly shorten the measurement time, a variety of user-friendly features, more suitable for the busy modern women.Health information, women's health, health knowledge, health knowledge network Roland Dean, good health, and the white-collar health knowledge, health, maternal and child knowledge, sexual life
