Question

我在 trouble忙地为以下这些密码的图像挑选人。原文为$(g.gallery )[0];将投入使用,但它也尝试了$(g.advance-link )和$( gallery ).find(img) [0];。

感谢你们的帮助!

JS Fiddle:

传真:

<div class="gallery front">
    <span class="image-wrapper current">
        <a class="advance-link" rel="history" href="#1" title="Title #10">
            <img alt="Title #10" src="../img/10.jpeg">
        </a>
    </span>
</div>

Answer 1

有了这种构造,就有很多机会获得图像:

快速而容易

$( .advance-link>img )

(仅供参考:)

$( div.gallery.front>span.image-wrapper.current>a.advance-link>img )

Answer 2

$( .gallery .image-wrapper .advance-link img ).css( border ,  10px solid black );

仅像CSS选择者一样使用。

如同,对事先连接的管治所含每一图像进行检测,必须由图像-图像-图像-图像-校正控制在“彩色”内。

如果你想要获得“金”结果,请考虑:

result[0] will give you the DOM node and no jQuery object, so result[0].attr( href ) will be an error

result.eq(0) will give you a jQuery Object just containing the first result, so result.eq(0).attr( href ) will work.

Answer 3

$( .gallery img ).addClass( test );

Answer 4

$(>div.gallery img” should work

Answer 5

$( img.gallery ) your image doesnt have the class gallery one of its parents does. $( img.advance-link ) your image doesnt have the class advance-link its parent does.

Answer 6

$ ("img:eq(0)”).addClass (“test”);
