1.2 新增nextAll([selector])
selector (String) 可选参数,用于匹配元素的选择器字符串
Given a jQuery object that represents a set of DOM elements, the .nextAll()
method allows us to search through the successors 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 selector is supplied, the elements will be filtered by testing whether they match it.
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 elements which come after it:
$('li.third-item').nextAll().css('background-color', 'red');
The result of this call is a red background behind items 4 and 5. Since we do not supply a selector expression, these following elements are unequivocally included as part of the object. If we had supplied one, the elements would be tested for a match before they were included.
示例:
Locate all the divs after the first and give them a class.
<!DOCTYPE html>
<html>
<head>
<style>
div { width: 80px; height: 80px; background: #abc;
border: 2px solid black; margin: 10px; float: left; }
div.after { border-color: red; }
</style>
<script src="jquery.min.js"></script>
</head>
<body>
<div>first</div>
<div>sibling<div>child</div></div>
<div>sibling</div>
<div>sibling</div>
<script>
$("div:first").nextAll().addClass("after");
</script>
</body>
</html>
