1. app end() and prepend()
Assume that
<p class='a'> //<---you want p c to append in this <p class='b'>b</p> </p>
is used
$('.a').append($('.c'));
The effect is as follows:
<p class='a'> //<---you want p c to append in this <p class='b'>b</p> <p class='c'>c</p> </p>
Similarly use
$('.a').prepend($('.c'));
The effect is as follows:
<p class='a'> //<---you want p c to append in this <p class='c'>c</p> <p class='b'>b</p> </p>
2. Use after() and before()
Also use the hypothetical code:
$('.a').after($('.c'));
The effect is as follows:
<p class='a'> <p class='b'>b</p></p><p class='c'>c</p>
Also use before()
$('.a').before($('.c'));
The effect is as follows:
<p class='c'>c</p><p class='a'> <p class='b'>b</p></p>
Summary:
append() & prepend() insert content into the element (the content becomes a child element or node of the element), after () & before() inserts content outside the element (its content becomes the sibling node of the element)
