如何防止我的锚点如此多地跳到我的屏幕上?

标签: javascript css anchor pseudo-class fragment-identifier

我决定尝试使用CSS和HTML创建一个标签式菜单。使用:target伪类来显示适当的div,我实现了它,只是它跳得太多而不方便用户使用:

无论如何我能解决这个问题吗?最初,我想远离JavaScript,但如果能解决这个问题,我会很乐意添加一些。

注意:我知道我可以使用jQuery /某些花哨的库重建一个新的选项卡式菜单,但如果可能的话,我宁愿修复它。

因为您在锚中使用哈希值。这会导致它跳转到具有哈希指定的id的div。

要对此进行排序,您可以使用jQuery通过.preventDefault();

来停止跳转

你可以通过给每个跳过prevent类的锚点然后使用jQuery来停止跳跃来使用它。当然,您可以根据您的html结构更改此选择器。

$(".prevent").click(function(e) { //Note the e for event
  e.preventDefault();
});

不使用jQuery编辑

在诅咒没有使用jQuery之后,我试图整合一个纯粹的js解决方案。您需要检查一下以确保它在您的页面上有效。

Here is the jsfiddle example

我所做的是找到页面上的所有锚点,然后在其onclick属性中添加return false。如果要在您的实际网站上进行此操作,则需要进一步选择锚点,请参阅此example和解释:

我还为你不想跳的锚添加了一个类。要使用此功能,您需要将“menuControl”类添加到要停止跳转的任何锚点。

以下是我的JavaScript,因为jsfiddle链接被破坏了。仅举几个例子,您现在需要使用JavaScript控制这些标签的导航,因为使用return false将停止导航。

var anchors = document.getElementsByTagName("a");

for(var i = 0; i < anchors.length; i++) {
    if ( anchors[i].className == "menuControl" ) {
        anchors[i].setAttribute("onclick", "return false");
    }
} ​

您可以在每次点击后使用window.scrollTo(0, 0);滚动回到文档的顶部,很可能发生的速度太快,任何用户都无法注意到。

对于水平跳跃,您可以在身体上使用overflow-y: scroll,以便滚动条始终位于页面上,即使内容不足以导致滚动。

答案 2 :(得分:2)

您可以将页面的最小高度设置为div使用css移动到顶部所需的高度。

body { min-height: 1000px; } 

用你需要的px替换1000px。

这样可以防止所有跳转超出使浏览器视图成为div的初始点击。

就像点击“销售订单处理”然后单击“现在订购处理”一样。如果您不想在页面加载时显示所有额外的空白区域,则只有在单击选项卡时才能设置高度。

我会使用jQuery使其顺利滚动。有一个很好的演示here

答案 4 :(得分:1)

$(window).scroll(function () { 
       var newTop = $(window).scrollTop();
       if (newTop <= 130){
            newTop = 130;
       }
       $("#idofElementToScroll").stop()
       .animate({'top': newTop}, "slow");
});

这是我在个人网站上的私人部分编写和实现的功能。

这里发生的事情是你声明你当前在屏幕上的位置,然后向下滚动你滚动的元素顺利滚动。

我知道您要求移动锚点,但您可以非常轻松地将此功能用于此目的。

请注意,'130'指的是我希望移动元素位于窗口顶部的最小距离。

祝你好运!

你遇到了问题,因为你的容器高度是如此不同。

我建议你将所有内容容器包装在一个无样式的div中。然后循环遍历所有容器。计算容器的最大高度。然后给所有包装div这个最大高度。

使用带有目标伪类的兄弟选择器来避免此问题,遵循Stu Nicholls的示例,但要注意Webkit bug

        <h2>John Constable</h2>
        <img src="painters/constable2.jpg" alt="The Hay Wain" title="The Hay Wain" />
        <p>Although he showed an early talent for art and began painting his native Suffolk scenery before he left school, his great originality matured slowly.</p>
        <p>He committed himself to a career as an artist only in 1799, when he joined the Royal Academy Schools and it was not until 1829 that he was grudgingly made a full Academician, elected by a majority of only one vote.</p>
        <p>In 1816 he became financially secure on the death of his father and married Maria Bicknell after a seven-year courtship and in the fact of strong opposition from her family. During the 1820s he began to win recognition: The Hay Wain (National Gallery, London, 1821) won a gold medal at the Paris Salon of 1824 and Constable was admired by <a href="http://www.ibiblio.org/wm/paint/auth/delacroix/">Delacroix</a> and Bonington among others.</p>
        <p>His wife died in 1828, however, and the remaining years of his life were clouded by despondency.</p>

        <h2>Claude Monet</h2>
        <img src="painters/monet2.jpg" alt="Women in the Garden" title="Women in the Garden" />
        <p>His youth was spent in Le Havre, where he first excelled as a caricaturist but was then converted to landscape painting by his early mentor <a href="http://www.ibiblio.org/wm/paint/auth/boudin/">Boudin</a>, from whom he derived his firm predilection for painting out of doors.</p>
        <p>In 1859 he studied in Paris at the Atelier Suisse and formed a friendship with <a href="http://www.ibiblio.org/wm/paint/auth/pissarro/">Pissarro</a>. After two years' military service in Algiers, he returned to Le Havre and met <a href="http://www.ibiblio.org/wm/paint/auth/jongkind/">Jongkind</a>, to whom he said he owed `the definitive education of my eye'.</p>
        <p>He then, in 1862, entered the studio of Gleyre in Paris and there met Renoir, Sisley, and Bazille, with whom he was to form the nucleus of the Impressionist group.</p> 
        <p>Monet's devotion to painting out of doors is illustrated by the famous story concerning one of his most ambitious early works, Women in the Garden (Mus&#233;e d'Orsay, Paris; 1866-67). The picture is about 2.5 meters high and to enable him to paint all of it outside he had a trench dug in the garden so that the canvas could be raised or lowered by pulleys to the height he required.</p>

        <p>Gogh, Vincent (Willem) van (b. March 30, 1853, Zundert, Neth.--d. July 29, 1890, Auvers-sur-Oise, near Paris), generally considered the greatest Dutch painter and draughtsman after <a href="http://www.ibiblio.org/wm/paint/auth/rembrandt/">Rembrandt</a>.</p>
        <p>With <a href="http://www.ibiblio.org/wm/paint/auth/cezanne/">C&#233;zanne</a> and <a href="http://www.ibiblio.org/wm/paint/auth/gauguin/">Gauguin</a> the greatest of Post-Impressionist artists. He powerfully influenced the current of <a href="http://www.ibiblio.org/wm/paint/glo/expressionism/">Expressionism</a> in modern art. His work, all of it produced during a period of only 10 years, hauntingly conveys through its striking colour, coarse brushwork, and contoured forms the anguish of a mental illness that eventually resulted in suicide. Among his masterpieces are numerous self-portraits and the well-known <a href="http://www.ibiblio.org/wm/paint/auth/gogh/starry-night/">The&nbsp;Starry&nbsp;Night</a> (1889).</p>

        <h2>Marc Chagall</h2>
        <img src="painters/chagall2.jpg" alt="Adam and Eve" title="Adam and Eve" />
        <p>Russian-born French painter. Born to a humble Jewish family in the ghetto of a large town in White Russia, Chagall passed a childhood steeped in Hasidic culture.</p>
        <p>Very early in life he was encouraged by his mother to follow his vocation and she managed to get him into a St Petersburg art school. Returning to Vitebsk, he became engaged to Bella Rosenfeld (whom he married twelve years later), then, in 1910, set off for Paris, 'the Mecca of art'.</p>
        <p>He was a tenant at La Ruche, where he had Modigliani and Soutine for neighbours. His Slav Expressionism was tinged with the influence of <a href="http://www.artchive.com/artchive/D/daumier.html">Daumier</a>, Jean-Fran&#231;ois Millet, the Nabis and the Fauves.</p>
        <p>He was also influenced by <a href="http://www.artchive.com/artchive/cubism.html">Cubism</a>. Essentially a colourist, Chagall was interested in the Simultaneist vision of Robert Delaunay and the Luminists of the Section d'Or.</p>

        <p>Pablo Picasso, born in Spain, was a child prodigy who was recognized as such by his art-teacher father, who ably led him along.</p>
        <p>The small Museo de Picasso in Barcelona is devoted primarily to his <a href="http://www.artchive.com/artchive/P/picasso_early.html">early works</a>, which include strikingly realistic renderings of casts of ancient sculpture.</p>
        <p>He was a rebel from the start and, as a teenager, began to frequent the Barcelona cafes where intellectuals gathered.</p>
        <p>He soon went to Paris, the capital of art, and soaked up the works of Manet, Gustave Courbet, and <a href="http://www.artchive.com/artchive/T/toulouse-lautrec.html">Toulouse-Lautrec</a>, whose sketchy style impressed him greatly. Then it was back to Spain, a return to France, and again back to Spain - all in the years 1899 to 1904.</p>

这应该可以解决锚点固定的问题。它可以跳一次,但之后就不会了。
