我有2个div(动态创建),我想为这些现有的div添加父div。
HTML: -
<div id="a">div1</div>
<div id="b">div2</div>
输出应该是这样的: -
<div id="1">Main Div
<div id="a">div1</div>
<div id="b">div2</div>
</div>

使用.wrapAll()
- 围绕匹配元素集中的所有元素包装HTML结构。
$( ".inner" ).wrapAll( "<div id='1' />");
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.0/jquery.min.js"></script>
<div class="inner" id="a">div 1</div>
<div class="inner" id="b">div 2</div>
&#13;

向DOM元素添加类
$( ".inner" ).wrapAll( "<div id='1' />");
然后使用jQuery
#include <stdio.h>
#include <stdlib.h>
#include <iostream>
using namespace std;
class A
{
public:
void aFunction()
{
cout<<"This is aFunction"<<endl;
}
private:
void anotherFunction()
{
cout<<"This is anotherFunction"<<endl;
}
};
class B: public A
{
public:
void anotherFunction()
{
cout<<"This is also anotherFunction, but it's accessible!"<<endl;
}
};
int main(int argc, char* argv[])
{
A firstClass;
B coach;
firstClass.aFunction();
coach.anotherFunction();
return 0;
}
