.next()
Get the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.
.next(selector)🡢 jQuery
selector
| Selector | A string containing a selector expression to match elements against. |
Given a jQuery object that represents a set of DOM elements, the .next() method allows us to search through the immediately following sibling of these elements in the DOM tree and construct a new jQuery object from the matching elements.
The method optionally accepts a selector expression of the same type that we can pass to the $() function. If the immediately following sibling matches the selector, it remains in the newly constructed jQuery object; otherwise, it is excluded.
Consider a page with a simple list on it:
<ul>
<li>list item 1</li>
<li>list item 2</li>
<li class="third-item">list item 3</li>
<li>list item 4</li>
<li>list item 5</li>
</ul>
If we begin at the third item, we can find the element which comes just after it:
$("li.third-item").next().css("background-color", "red");
The result of this call is a red background behind item 4. Since we do not supply a selector expression, this following element is unequivocally included as part of the object. If we had supplied one, the element would be tested for a match before it was included.
Find the very next sibling of each disabled button and change its text "this button is disabled".
<div><button disabled="disabled">First</button> - <span></span></div>
<div><button>Second</button> - <span></span></div>
<div><button disabled="disabled">Third</button> - <span></span></div>
span {
color: blue;
font-weight: bold;
}
button {
width: 100px;
}
$("button[disabled]").next().text("this button is disabled");
Find the very next sibling of each paragraph. Keep only the ones with a class "selected".
<p>Hello</p>
<p class="selected">Hello Again</p>
<div><span>And Again</span></div>
$("p").next(".selected").css("background", "yellow");
