、什么是面向?qū)ο?
面向?qū)ο髢H僅是一個(gè)概念或者編程思想
通過(guò)一種叫做原型的方式來(lái)實(shí)現(xiàn)面向?qū)ο缶幊?/p>
1、 創(chuàng)建對(duì)象(自定義對(duì)象,內(nèi)置對(duì)象)
基于Object對(duì)象的方式創(chuàng)建對(duì)象-自定義對(duì)象
示例:
var 對(duì)象名稱(chēng)=new Object( );
var flower=new Object();
flower.name="長(zhǎng)春花";
flower.genera="夾竹桃科 長(zhǎng)春花屬";
flower.area="非洲、亞熱帶、熱帶以及中國(guó)大陸的華東、西南、中南等地";
flower.uses="觀(guān)賞或用藥等";
flower.showName=function(){ alert(this.name); }
flower.showName();
常見(jiàn)的內(nèi)置對(duì)象
String（字符串）對(duì)象
Date（日期）對(duì)象
Array（數(shù)組）對(duì)象
Boolean（邏輯）對(duì)象
Math（算數(shù)）對(duì)象
RegExp對(duì)象
二、
如何解決使用同一個(gè)接口不需要?jiǎng)?chuàng)建很多對(duì)象，減少產(chǎn)生大量的重復(fù)代碼？
1、構(gòu)造函數(shù):
function Flower(name,genera,area,uses){
this.name=name;
…….
this.showName=function(){
alert(this.name);
}
}
var flower1=new Flower("長(zhǎng)春花","夾竹桃科 長(zhǎng)春花屬","非洲、亞熱帶、熱帶以及中國(guó)大陸的華東、西南、中南等地","觀(guān)賞或用藥等")
flower1.showName();
2、原型對(duì)象:
function Flower(){
}
Flower.prototype.name="曼陀羅花";
Flower.prototype.genera="茄科 曼陀羅屬";
Flower.prototype.area="印度、中國(guó)北部";
Flower.prototype.uses="觀(guān)賞或藥用";
Flower.prototype.showName=function() {
alert(this.name);
}
var flower1=new Flower();
flower1.showName();
var flower2=new Flower();
flower2.showName();
alert(flower1.showName==flower2.showName);
三、繼承
1.原型鏈:一個(gè)原型對(duì)象是另一個(gè)原型對(duì)象的實(shí)例
相關(guān)的原型對(duì)象層層遞進(jìn)，就構(gòu)成了實(shí)例與原型的鏈條，就是原型鏈
示例:
function Humans(){
this.foot=2;
}
Humans.prototype.getFoot=function(){
return this.foot;
}
function Man(){
this.head=1;
}
Man.prototype=new Humans(); //繼承了Humans
Man.prototype.getHead=function(){
return this.head;
}
var man1=new Man();
alert(man1.getFoot()); //2
alert(man1 instanceof Object); //true
alert(man1 instanceof Humans); //true
alert(man1 instanceof Man); //true
2.對(duì)象繼承:
function Humans(){
this.clothing=["trousers","dress","jacket"];
}
function Man(){ }
//繼承了Humans
Man.prototype=new Humans();
var man1=new Man();
man1.clothing.push("coat");
alert(man1.clothing);
var man2=new Man();
alert(man2.clothing);
3.組合繼承:
組合繼承：有時(shí)也叫做偽經(jīng)典繼承
將原型鏈和借用構(gòu)造函數(shù)的技術(shù)組合到一塊，發(fā)揮二者之長(zhǎng)的一種繼承模式
使用原型鏈實(shí)現(xiàn)對(duì)原型屬性和方法的繼承，而通過(guò)借用構(gòu)造函數(shù)來(lái)實(shí)現(xiàn)對(duì)實(shí)例屬性的繼承

內(nèi)容來(lái)源于@什么值得買(mǎi)APP，觀(guān)點(diǎn)僅代表作者本人 ｜作者：突突兔too禿
老婆做進(jìn)出口的，前一段發(fā)了一個(gè)知識(shí)貼給我，以為是要打印，搞了半天是因?yàn)榫W(wǎng)頁(yè)不讓復(fù)制，所以分享給我。
這可笑壞我了，還有什么方法能突破“禁止復(fù)制”禁術(shù)，當(dāng)然唯我漩渦鳴人的影分身之術(shù)了?？次胰绾位顚W(xué)活用，復(fù)制粘貼。
實(shí)際上，我覺(jué)得老婆大人的方法是最實(shí)際的了。這絕不僅僅是出于對(duì)老婆大人的尊重，而是實(shí)事求是。不讓復(fù)制就不復(fù)制唄。我也就平時(shí)存起來(lái)備查。當(dāng)然，如果實(shí)在找不到人分享，那就分享給“文件傳輸助手”吧。
有一種孤獨(dú)叫智能發(fā)給穿書(shū)助手
同樣的寂寞（劃掉）方法，我們也可以通過(guò)QQ把地址分享給“我的Android手機(jī)”。
比方法1稍微高級(jí)一點(diǎn)的是，將有關(guān)內(nèi)容在微信中打開(kāi)后，選擇“收藏”，這樣以后就可以直接在我的“收藏”中找到了。
當(dāng)然，以上方法還只是迂回作戰(zhàn)，說(shuō)白了禁術(shù)還在，只是找了個(gè)方法替代。真的如果需要復(fù)制的時(shí)候就白瞎了。
使用Chrome瀏覽器或者360瀏覽器，然后直接選擇部分文字，鼠標(biāo)按住左鍵，就可以把文字拖拽到QQ對(duì)話(huà)框了。
step1
step2
同樣是在360瀏覽器上面，鼠標(biāo)選擇要復(fù)制的文字，然后右擊鼠標(biāo)，選擇保存為文本。
step1
再選擇一個(gè)文件夾保存。
step2
打開(kāi)指定文件夾中的TXT文檔，就能得到相應(yīng)的文字了。
如果要評(píng)論這種生拉硬拽的方法，那就是霸氣。
當(dāng)然，也有不足，每一次都要這么拖拽，鼠標(biāo)手是跑不掉的了。而且并沒(méi)有辦法一次性全部選擇。
step1：使用QQ對(duì)話(huà)框的截圖工具。
step2：然后右擊圖片，選擇提取圖中文字。
step3：點(diǎn)擊下載。
step4：就可以在指定文件夾中找到picture和result兩個(gè)文件。馬上就能下載了。
當(dāng)然，這個(gè)和方法3一樣，不能全選，需要反復(fù)的復(fù)制粘貼。
使用手機(jī)自帶功能進(jìn)行滾動(dòng)截屏后，再打開(kāi)微信小程序“傳圖識(shí)字”，然后進(jìn)行orc識(shí)字，就可以復(fù)制了。
step1：我的手機(jī)是華為的，使用指關(guān)節(jié)寫(xiě)一個(gè)“S”，就可以滾動(dòng)截屏。
step2：然后進(jìn)入傳圖識(shí)字后，點(diǎn)擊“從相冊(cè)中選取”。
step3：點(diǎn)擊全選，然后復(fù)制，就可以在對(duì)話(huà)框中張貼了。
不過(guò)需要注意的是，過(guò)長(zhǎng)的圖片也可能出現(xiàn)識(shí)別失敗。像這次，我就只選擇了一半。而orc識(shí)別最大的問(wèn)題，還是準(zhǔn)確性。只能安慰自己就當(dāng)是檢查作業(yè)，外加復(fù)習(xí)了唄。
step1：使用手機(jī)edge，然后在網(wǎng)址中點(diǎn)擊閱讀模式；
step2：選擇“全選”-“復(fù)制”；
step3：再粘貼到備忘錄中。
同樣的方式，也可以在UC上使用。
比起edge和UC還要使用閱讀模式，夸克直接跳過(guò)了第一步。
難怪這款手機(jī)App會(huì)受到大家的喜歡。
在谷歌瀏覽器上打開(kāi)網(wǎng)頁(yè)，點(diǎn)擊“F12”，又或者在網(wǎng)頁(yè)上點(diǎn)擊右鍵，選擇“檢查”。
然后再選擇“setting”或者直接按“F1”，然后找到debugger-disable Javascript，勾選，就可以復(fù)制粘貼了。
不過(guò)，記得用完取消勾選disable-Javascript，需要的時(shí)候才開(kāi)啟。
總結(jié)一下，其實(shí)無(wú)非就是三種方法，一種是聽(tīng)之任之，一種是使用其他工具進(jìn)行orc識(shí)別，最后一種就是破壞網(wǎng)頁(yè)的規(guī)則。以上的方法大部分也是小白級(jí)別，還沒(méi)涉及到油猴腳本等等。但是貴在實(shí)用，平時(shí)有文案撰寫(xiě)、論文寫(xiě)作等需求的值友歡迎收藏，畢竟用的時(shí)候才能記得住。
為工作中經(jīng)常用到這些方法，所有便把這些方法進(jìn)行了總結(jié)。
