、什么是面向对象?
面向对象仅仅是一个概念或者编程思想
通过一种叫做原型的方式来实现面向对象编程
1、 创建对象(自定义对象,内置对象)
基于Object对象的方式创建对象-自定义对象
示例:
var 对象名称=new Object( );
var flower=new Object();
flower.name="长春花";
flower.genera="夹竹桃科 长春花属";
flower.area="非洲、亚热带、热带以及中国大陆的华东、西南、中南等地";
flower.uses="观赏或用药等";
flower.showName=function(){ alert(this.name); }
flower.showName();
常见的内置对象
String(字符串)对象
Date(日期)对象
Array(数组)对象
Boolean(逻辑)对象
Math(算数)对象
RegExp对象
二、
如何解决使用同一个接口不需要创建很多对象,减少产生大量的重复代码?
1、构造函数:
function Flower(name,genera,area,uses){
this.name=name;
…….
this.showName=function(){
alert(this.name);
}
}
var flower1=new Flower("长春花","夹竹桃科 长春花属","非洲、亚热带、热带以及中国大陆的华东、西南、中南等地","观赏或用药等")
flower1.showName();
2、原型对象:
function Flower(){
}
Flower.prototype.name="曼陀罗花";
Flower.prototype.genera="茄科 曼陀罗属";
Flower.prototype.area="印度、中国北部";
Flower.prototype.uses="观赏或药用";
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、继承
1.原型链:一个原型对象是另一个原型对象的实例
相关的原型对象层层递进,就构成了实例与原型的链条,就是原型链
示例:
function Humans(){
this.foot=2;
}
Humans.prototype.getFoot=function(){
return this.foot;
}
function Man(){
this.head=1;
}
Man.prototype=new Humans(); //继承了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.对象继承:
function Humans(){
this.clothing=["trousers","dress","jacket"];
}
function Man(){ }
//继承了Humans
Man.prototype=new Humans();
var man1=new Man();
man1.clothing.push("coat");
alert(man1.clothing);
var man2=new Man();
alert(man2.clothing);
3.组合继承:
组合继承:有时也叫做伪经典继承
将原型链和借用构造函数的技术组合到一块,发挥二者之长的一种继承模式
使用原型链实现对原型属性和方法的继承,而通过借用构造函数来实现对实例属性的继承

老婆做进出口的,前一段发了一个知识贴给我,以为是要打印,搞了半天是因为网页不让复制,所以分享给我。
这可笑坏我了,还有什么方法能突破“禁止复制”禁术,当然唯我漩涡鸣人的影分身之术了。看我如何活学活用,复制粘贴。
实际上,我觉得老婆大人的方法是最实际的了。这绝不仅仅是出于对老婆大人的尊重,而是实事求是。不让复制就不复制呗。我也就平时存起来备查。当然,如果实在找不到人分享,那就分享给“文件传输助手”吧。
有一种孤独叫智能发给穿书助手
同样的寂寞(划掉)方法,我们也可以通过QQ把地址分享给“我的Android手机”。
比方法1稍微高级一点的是,将有关内容在微信中打开后,选择“收藏”,这样以后就可以直接在我的“收藏”中找到了。
当然,以上方法还只是迂回作战,说白了禁术还在,只是找了个方法替代。真的如果需要复制的时候就白瞎了。
使用Chrome浏览器或者360浏览器,然后直接选择部分文字,鼠标按住左键,就可以把文字拖拽到QQ对话框了。
step1
step2
同样是在360浏览器上面,鼠标选择要复制的文字,然后右击鼠标,选择保存为文本。
step1
再选择一个文件夹保存。
step2
打开指定文件夹中的TXT文档,就能得到相应的文字了。
如果要评论这种生拉硬拽的方法,那就是霸气。
当然,也有不足,每一次都要这么拖拽,鼠标手是跑不掉的了。而且并没有办法一次性全部选择。
step1:使用QQ对话框的截图工具。
step2:然后右击图片,选择提取图中文字。
step3:点击下载。
step4:就可以在指定文件夹中找到picture和result两个文件。马上就能下载了。
当然,这个和方法3一样,不能全选,需要反复的复制粘贴。
使用手机自带功能进行滚动截屏后,再打开微信小程序“传图识字”,然后进行orc识字,就可以复制了。
step1:我的手机是华为的,使用指关节写一个“S”,就可以滚动截屏。
step2:然后进入传图识字后,点击“从相册中选取”。
step3:点击全选,然后复制,就可以在对话框中张贴了。
不过需要注意的是,过长的图片也可能出现识别失败。像这次,我就只选择了一半。而orc识别最大的问题,还是准确性。只能安慰自己就当是检查作业,外加复习了呗。
step1:使用手机edge,然后在网址中点击阅读模式;
step2:选择“全选”-“复制”;
step3:再粘贴到备忘录中。
同样的方式,也可以在UC上使用。
比起edge和UC还要使用阅读模式,夸克直接跳过了第一步。
难怪这款手机App会受到大家的喜欢。
在谷歌浏览器上打开网页,点击“F12”,又或者在网页上点击右键,选择“检查”。
然后再选择“setting”或者直接按“F1”,然后找到debugger-disable Javascript,勾选,就可以复制粘贴了。
不过,记得用完取消勾选disable-Javascript,需要的时候才开启。
总结一下,其实无非就是三种方法,一种是听之任之,一种是使用其他工具进行orc识别,最后一种就是破坏网页的规则。以上的方法大部分也是小白级别,还没涉及到油猴脚本等等。但是贵在实用,平时有文案撰写、论文写作等需求的值友欢迎收藏,毕竟用的时候才能记得住。
为工作中经常用到这些方法,所有便把这些方法进行了总结。
