How to get parent in jquery

When using jQuery, getting the parent element of an element is a common requirement. jQuery provides multiple methods to get the parent of an element.

Common methods to obtain the parent include parent(), parentUntil(), closest(), etc. These methods require a selector to select the parent element. These methods will be introduced one by one below.

1. parent()

parent() method can get the direct parent element of an element. For example, we can use the following code to get the parent of an element:

$("#child").parent();

The "child" here is the ID of a child element, and we can get its parent element through this method. If we want to obtain the attributes, styles, etc. of the parent element, we can use other jQuery methods to achieve this. For example:

$("#child").parent().attr("class");
$("#child").parent().css("color", "red");

2. parentsUntil()

parentsUntil() method can get the parent elements of an element until the specified ancestor element. For example:

$("#child").parentsUntil("#ancestor");

Here "child" is the ID of a child element, and "ancestor" is the ID of an ancestor element. This method returns all ancestor elements of the child whose ancestors are not found.

Similarly, we can use other jQuery methods to manipulate these elements.

3. closest()

closest() method is used to get the nearest parent element of an element, which must match the specified selector. For example:

$("#child").closest(".parent");

The ".parent" here is a selector matching the parent element. This method returns the nearest parent element that matches the selector.

Similarly, we can use other jQuery methods to manipulate these elements. For example:

$("#child").closest(".parent").attr("class");
$("#child").closest(".parent").css("color", "red");

Summary

In jQuery, getting the parent element of an element is a very common requirement. In order to achieve this goal, we can use methods such as parent(), parentUntil(), and closest(). These methods all need to choose the corresponding selector according to the specific situation. Through these methods, we can get the parent element of the element and operate on it.
