It can be seen that the value of parent is very clear, which is the parent element of the current element; parents is the ancestor element of the current element. Examples are listed below:
$('p').parent() gets div2, div3, div4 $('p').parent('.a') gets div3 $('p').parent().parent() obtains div1, which is rather strange; however, the characteristics of the Jquery object itself determine that this is feasible. $('p').parents() gets div1, div2, div3, div4 $('p').parents('.a') gets div3 parent (exp) Usage: Get an element set containing the unique parent element of all matching elements.
Among them: this.parent() is the td in front of input this.parent().parent() gets tr this.parent( ).parent().parent() obtains table this.parent().next() obtains td adjacent to td. In the example:
Hello
Hello
$("p").parent() gets:
Hello
< ;p>Hello
object, because the parent tag of the p tag is div
