Global
在 JavaScript 中什么是全局對象？
- 簡單來說，在 JavaScript 中，有那么一個對象，它的所有屬性可以在程序中的任何地方調用、訪問，並且所有在全局創建的變量常量都會綁定在這個對象上，那么這一個對象就是全局對象。
- 全局對象只是一個對象，它不是類，它沒有構造函數，也無法實例化一個新的全局對象，在一個程序中有且只有一個全局對象。
- 真實的全局對象是不可以被直接訪問的，通過關鍵字可以引用全局對象，被引用的是全局對象的代理，雖然真實全局對象和全局對象代理有所區別，但在平時使用中，可以直接把引用的全局對象代理當作真實的全局對象使用。
- 在瀏覽器環境中，JavaScript 的全局對象就是 Window 對象。在瀏覽器中運行 JavaScript ，全局對象會和 window 對象結合，相當全局對象於寄生 window 對象，可以通過 window 對象訪問全局對象的所有屬性。
- 在node.js 環境中，JavaScript 的全局對象是 Global 對象。在 node.js 環境中，可以通過 global 對象訪問全局對象的所有屬性。
- 其他環境，比如微信小程序等環境，這種也可以看作一個瀏覽器，不過這個瀏覽器通過刪減一些不用的屬性再添加或修改一些自定義的屬性變成一個新的瀏覽器環境，但其核心還是沒有變化的。當然，這種瀏覽器環境的全局對象同樣也是 Window 對象。
不同 JavaScript 環境中怎么獲取全局對象？
由於在 JavaScript 中，全局對象不是任何對象的屬性，它沒有自己的名稱，但在頂層 JavaScript 中，大部分情況下可以使用關鍵字 this、window 引用全局對象（node.js 環境中不可以，其宿主與瀏覽器環境不同）。
關於使用關鍵字引用全局對象，下面整理了一個表格，可以進行查看：
/* ; 下表中數據含意： ; g : 表示輸出全局對象 ; - 瀏覽器：window（含各內置對象、本地對象、BOM、DOM） ; - 小程序：window（含部分內置對象、部分本地對象、一些自定義對象、少量BOM、極少DOM） ; - node ：全局對象（含各內置對象、無window、無DOM、極少極少BOM） ; n : 表示其他非全局對象的對象（node 中，全局this為空對象，准確說應該是 module.exports。函數中的this為全局對象 global） ; / : 表示輸出 not defined ---------------------------------------------------------------- ; : IE : 正常瀏覽器 : node : 小程序 ; ;--------------------------------------------------------------- ;this : g : g : n : g ; ;self : g : g : / : g ; ;window : g : g : / : g ; ;global : / : / : g : n ; ;globalTthis : / : g : g : / ; ;top : g : g : / : g ; ;parent : g : g : / : g ; ;frames : g : g : / : / ; ---------------------------------------------------------------- */
各瀏覽器中全局對象的屬性數量：
通過測試，得到市面上比較流行的瀏覽器在空頁面時全局對象的屬性的數量（大概數量，同樣瀏覽器不同版本都會有所不同）：
常見瀏覽器：
- google：960+
- opera：950+
- firefox：810+
- safari：760+
- 360：920+
- edge：670+
- ie-11：470+
- ie-10：410+
- ie-9：320+
其他 Javascript 環境：
- 微信小程序：180+
- node：70+
全局對象的屬性：
由於不同環境全局對象的屬性都不盡相同，甚至同一個環境不同版本的全局對象屬性都有不同，下面主要列出 google 瀏覽器( 版本 83.x+) 和 node.js( 版本 14.x+)的全局對象所有屬性：
瀏覽器中的全局對象的屬性：

瀏覽器環境和 node.js 環境全局對象屬性對比：
既然列出了瀏覽器和 node.js 的全局對象屬性，那就稍微對比一下在 node.js 環境中多了哪些屬性吧。
// 在 node.js 環境中， 通過 Object.getOwnPropertyNames(globalThis) 得到以下 NodeGlobalThisPropsNames var NodeGlobalThisPropsNames = [ 'Object', 'Function', 'Array', 'Number', 'parseFloat', 'parseInt', 'Infinity', 'NaN', 'undefined', 'Boolean', 'String', 'Symbol', 'Date', 'Promise', 'RegExp', 'Error', 'EvalError', 'RangeError', 'ReferenceError', 'SyntaxError', 'TypeError', 'URIError', 'globalThis', 'JSON', 'Math', 'console', 'Intl', 'ArrayBuffer', 'Uint8Array', 'Int8Array', 'Uint16Array', 'Int16Array', 'Uint32Array', 'Int32Array', 'Float32Array', 'Float64Array', 'Uint8ClampedArray', 'BigUint64Array', 'BigInt64Array', 'DataView', 'Map', 'BigInt', 'Set', 'WeakMap', 'WeakSet', 'Proxy', 'Reflect', 'decodeURI', 'decodeURIComponent', 'encodeURI', 'encodeURIComponent', 'escape', 'unescape', 'eval', 'isFinite', 'isNaN', 'SharedArrayBuffer', 'Atomics', 'WebAssembly', 'global', 'process', 'Buffer', 'URL', 'URLSearchParams', 'TextEncoder', 'TextDecoder', 'clearInterval', 'clearTimeout', 'setInterval', 'setTimeout', 'queueMicrotask', 'clearImmediate', 'setImmediate' ] // 在瀏覽器環境中（本例子為 google），獲得以下 googleGlobalThisPropsNames // 大概有近千個屬性，由於篇幅關系就不一一列出了，可以參考上面的 瀏覽器中的全局對象的屬性 var googleGlobalThisPropsNames = Object.getOwnPropertyNames(globalThis) // 過濾出 node.js 獨有的全局對象屬性 var nodeProps = NodeGlobalThisPropsNames var webProps = googleGlobalThisPropsNames var noRepProps = nodeProps.filter(i=>webProps.indexOf(i)===-1) // 打印得到 noRepProps = ['global','process','Buffer','clearImmediate','setImmediate']
得到過濾后的 node.js 全局屬性：
- global 用於指向全局對象。
- clearImmediate 和 setImmediate 是用於執行回調函數的定時器，一個 set 一個 clear 和其他定時器使用相似，其實在新版的 IE 已經被提出，但由於各種因素應該不會成為標准。
- process 提供了有關當前 Node.js 進程的信息並對其進行控制。
- Buffer 用於以字節序列的形式來表示二進制數據。 Uint8Array 類的子類。
全局對象的常見屬性：
Infinity
功能：代表正的無窮大的數值。
注意：Infinity代表了超出JavaScript處理范圍的數值。也就是說JS無法處理的數值都是Infinity。實踐證明，JS所能處理的最大值是1.7976931348623157e+308，而最小值是5e-324。
示例：
console.log(6/0); //Infinity console.log(-6/0); //-Infinity console.log(0/0); //NaN console.log(1.7976931348623157E+10308); //Infinity console.log(-1.7976931348623157E+10308); //-Infinity
NaN
功能：代表非數字的值。
注意：請使用 isNaN() 方法來判斷一個值是否是數字，原因是 NaN 與所有值都不相等，包括它自己。
示例：
var a = Number('100'); var b = Number('hello world'); console.log(a); //100 console.log(b); //NaN console.log(isNaN(a)); //false console.log(isNaN(b)); //true
Undefined
功能：代表未定義的值。
注意：判斷一個變量是否未定義，只能用 === undefined 運算來測試，因為 == 運算符會認為 undefined 值等價於 null，即undefined == null會返回true。null 表示無值，而 undefined 表示一個未聲明的變量，或已聲明但沒有賦值的變量，或一個並不存在的對象屬性。
示例：
var a; var b = ''; var c = null; console.log(a === undefined); //true console.log(b === undefined); //false console.log(c == undefined); //true
全局對象的常見方法：
1、encodeURI(URIString)
功能：
- 將字符串作為URI進行編碼，返回值為URIstring 的副本。
- 該方法不會對 ASCII 字母和數字進行編碼，也不會對這些 ASCII 標點符號進行編碼： - _ . ! ~ * ' ( ) 。
- 該方法的目的是對 URI 進行完整的編碼，因此對以下在 URI 中具有特殊含義的 ASCII 標點符號，encodeURI() 函數是不會進行轉義的：;/?:@&=+$,#
- 提示：如果 URI 組件中含有分隔符，比如 ? 和 #，則應當使用 encodeURIComponent() 方法分別對各組件進行編碼。
參數：
- URIString(必須)：一個待編碼的字符串。
示例：
console.log(encodeURI('http://www.baidu.com')); //http://www.baidu.com
console.log(encodeURI('http://www.baidu.com/my mind')); //http://www.baidu.com/my%20mind
console.log(encodeURI(',/?:@&=+$#')); //,/?:@&=+$#
2、encodeURIComponent(URIString)
功能：
- 將字符串作為URI組件進行編碼，返回值為URIstring的副本。
- 該方法不會對 ASCII 字母和數字進行編碼，也不會對這些 ASCII 標點符號進行編碼： - _ . ! ~ * ' ( ) 。
- 其他字符（比如 ：;/?:@&=+$,# 這些用於分隔 URI 組件的標點符號），都是由一個或多個十六進制的轉義序列替換的。
參數：
- URIString(必須)：一個待編碼的字符串。
注意：encodeURI和encodeURIComponent的區別：
- 它們都是編碼URL，唯一區別就是編碼的字符范圍，其中encodeURI方法不會對下列字符編碼 ASCII字母、數字、~!@#$&*()=:/,;?+'
- encodeURIComponent方法不會對下列字符編碼 ASCII字母、數字、~!*()'
- 所以encodeURIComponent比encodeURI編碼的范圍更大。
- 實際例子來說，encodeURIComponent會把 http:// 編碼成 http%3A%2F%2F 而encodeURI卻不會。
- 相應的，存在decodeURI()和decodeURIComponent是用來解碼的，逆向操作。
示例：
// 當你需要編碼整個URL，然后使用這個URL，則使用encodeURI。 console.log(encodeURI('http://www.baidu.com/home/some other thing')); //編碼后為：http://www.baidu.com/home/some%20other%20thing; 其中，空格被編碼成了%20 //但是如果你用了encodeURIComponent console.log(encodeURIComponent('http://www.baidu.com/home/some other thing')); //http%3A%2F%2Fwww.baidu.com%2Fhome%2Fsome%20other%20thing 連 "/" 都被編碼了，整個URL已經沒法用了 // 當你需要編碼URL中的參數時，那么使用encodeURIComponent。 var param = "http://www.baidu.com/home/"; //param為參數 param = encodeURIComponent(param); var url = "http://www.baidu.com?next=" + param; console.log(url) //'http://www.baidu.com?next=http%3A%2F%2Fwww.baidu.com%2Fhome%2F' //顯然，參數中的 "/" 被編碼了，而如果用encodeURI肯定要出問題，因為后面的/是需要編碼的。
3、parseInt(string,radix)
功能：解析一個字符串，並返回一個整數。
參數：
- string(必須)：待解析的字符串
- radix(可選)：表示要解析的數字的基數。該值介於 2 ~ 36 之間。
如果省略該參數或其值為 0，則數字將以 10 為基礎來解析。如果它以 “0x” 或 “0X” 開頭，將以 16 為基數。如果該參數小於 2 或者大於 36，則 parseInt() 將返回 NaN。
示例：
console.log(parseInt('10')); //10
console.log(parseInt('11',9)); //10 (9+1)
console.log(parseInt('11',2)); //3 (2+1)
console.log(parseInt('17',8)); //15 (8+7)
console.log(parseInt('1f',16)); //31 (16+15)
console.log(parseInt('010')); //10
console.log(parseInt('0x0011')); //17
4、parseFloat()
功能：解析一個字符串，並返回一個浮點數。該函數指定字符串中的首個字符是否是數字。如果是，則對字符串進行解析，直到到達數字的末端為止。
參數：
- string(必須)：待解析的字符串
注意：開頭和結尾的空格是允許的。如果字符串的第一個字符不能被轉換為數字，那么 parseFloat() 會返回 NaN。如果只想解析數字的整數部分，請使用 parseInt() 方法。
示例：
console.log(parseFloat('10')); //10
console.log(parseFloat('10.00')); //10
console.log(parseFloat('10.33')); //10.33
console.log(parseFloat(' 60 ')); //60 首尾的空格會忽略
console.log(parseFloat('23 34 45')); //23 中間的空格不會忽略，會中斷
console.log(parseFloat('23 years')); //23
console.log(parseFloat('i am 23')); //NaN
5、isFinite(number)
功能：用於檢查其參數是否是無窮大。
參數：
- number(必須)：待檢測數字。
- 如果 number 是有限數字（或可轉換為有限數字），那么返回 true。否則，如果 number 是 NaN（非數字），或者是正、負無窮大的數，則返回 false。
示例：
console.log(isFinite(123)); //true console.log(isFinite(-1.23)); //true console.log(isFinite(5-2)); //true console.log(isFinite(0)); //true console.log(isFinite(0/0)); //false console.log(isFinite('Hello')); //false
6、isNaN(number)
功能：用於檢查其參數是否為非數字值。
參數：
- number(必須)：待檢測數字。
- 如果 number 是非數字值 NaN（或者能被轉換成NaN），返回 true，否則返回 false。
注意：isNaN() 函數通常用於檢測 parseFloat() 和 parseInt() 的結果，以判斷它們表示的是否是合法的數字。當然也可以用 isNaN() 函數來檢測算數錯誤，比如用 0 作除數的情況。
示例：
console.log(isNaN(123)); //false console.log(isNaN(-1.23)); //false console.log(isNaN(5-2)); //false console.log(isNaN(0)); //false console.log(isNaN(0/0)); //true console.log(isNaN('Hello')); //true
7、Number(object)
功能：把對象的值轉換為數字。
參數：
- object(必須)：待轉換的對象。
- 如果參數是 Date 對象，Number() 返回從1970年1月1日至今的毫秒數，即時間戳。如果對象的值無法轉換為數字，那么 Number() 函數返回 NaN。
示例：
console.log(Number(new Boolean(true))); //1 console.log(Number(new Boolean(false))); //0 console.log(Number(new Date())); //1506266494726 console.log(Number(new String('999'))); //999 console.log(Number(new String('999 888'))); //NaN
8、String(object)
功能：把對象的值轉換為字符串。
參數：
- object(必須)：待轉換的對象。
示例：
console.log(String(new Boolean(true))); //'true' console.log(String(new Boolean(false))); //'false' console.log(String(new Date())); //'Sun Sep 24 2017 23:25:43 GMT+0800 (CST)' console.log(String(new String('999'))); //'999' console.log(String(new String('999 888'))); //'999 888' console.log(String(12345)); //'12345'
