我有一个像这样的jQuery代码:
$(this).next().next().next().next().html('<span>anything</span>');
现在我想知道那些.next()
函数还有其他选择吗? (类似于4*next()
)
注意: .nextUntil()
对我没用,因为我没有任何线索可以在.nextUntil()
中使用它。 (我的HTML结构是动态的。换句话说,它不是常数。有时候最后的元素是span
,有时它是div
等等......)
编辑:以下是我的HTML结构的一些示例:
例1:
<button>click it</button>
<div>div1</div>
<div>div2</div>
<span>span1</span>
<a>a1</a> <!-- target !! and it should be <span>anything</span> -->
<div>div3</div>
例2:
<button>click it</button>
<span>span1</span>
<b>b1</b>
<span>span2</span>
<div>div1</div> <!-- target !! and it should be <span>anything</span> -->
<div>div2</div>
<div>div3</div>

您可以合并.nextAll()
/ .eq()
方法:
$(this).nextAll().eq(3);
作为旁注,.eq()
方法接受从零开始的索引,这意味着.eq(3)
将选择第四个元素。
$('div.nextAll span:first').nextAll().eq(3).addClass('selected');
$('div.multipleNext span:first').next().next().next().next().addClass('selected');
.selected {
color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="nextAll">
<span>1</span><span>2</span><span>3</span><span>4</span><span>5</span><span>6</span><span>7</span>
</div>
<div class="multipleNext">
<span>1</span><span>2</span><span>3</span><span>4</span><span>5</span><span>6</span><span>7</span>
</div>
或者,正如评论中所指出的,您还可以使用general sibling combinator, ~
和:eq()
选择器的组合:
$('~:eq(3)', this);
或:
$(this).find('~:eq(3)');
$('~:eq(3)', 'div.nextAll span:first').addClass('selected');
$('div.multipleNext span:first').next().next().next().next().addClass('selected');
.selected {
color: #f00;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="nextAll">
<span>1</span><span>2</span><span>3</span><span>4</span><span>5</span><span>6</span><span>7</span>
</div>
<div class="multipleNext">
<span>1</span><span>2</span><span>3</span><span>4</span><span>5</span><span>6</span><span>7</span>
</div>

可以使用next siblings selector,:eq()
。正如@JoshCrozier所指出的,.eq()
和:eq()
是基于0的索引
$("~ :eq(3)", this)
$("button").click(function() {
$("~ :eq(3)", this).html("<span>anything</span>")
})
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button>click it</button>
<div>div1</div>
<div>div2</div>
<span>span1</span>
<a>a1</a> <!-- target !! and it should be <span>anything</span> -->
<div>div3</div>
