html - 链接到当前页面中的元素

Question

我创建了一个 HTML 页面，其中包含许多带有如下标题的表格：Content、Main_Page、Document、Expenses 等。

我想为页面顶部创建一个链接。当我单击该链接时，它应该转到特定部分。所以我使用下面的代码来映​​射内容。但这对我不起作用。

<a href="#Content">Content Section</a>

Answer 1

您需要为链接创建一个锚点。这样做的现代方法是给适当的元素一个id="Content"属性。这样做的旧方法是使用<a name="Content"></a>.

Answer 2

将要“跳转”的元素指定为明确的 ID，如下所示：

<p id="idOfTag">Your content goes here</p>

然后在页面顶部的链接中，使其引用该元素的 id（注意#）：

<a href="#idOfTag">Jump</a>

具有多个链接的完整示例：

<ul>
  <li><a href="#contentParagraph">Content</a></li>
  <li><a href="#mainPageParagraph">Main page</a></li>
  <li><a href="#documentParagraph">Document</a></li>
  <li><a href="#expensesParagraph">Expenses</a></li>
</ul>
<p id="contentParagraph">

Answer 3

您可以使用标签的name属性anchor来实现这一点。

假设你有一个div带 idcontent

<div id="content">This is my div</div>

接下来确保您有一个与 的属性相同的anchor标签nameiddiv content

<a href="#" name="content">Click to go to the top</a>

现场演示。

向下滚动以查看链接

另一种方法是

<div id="content">My div</div>

那么你的锚标签的href应该是#content

<a href="#content">Click to go to top</a>

看起来这个问题已经得到解答，但是如果你想在过渡到这些元素时使用滚动效果，这里有一点 JS 片段。$（函数（）{

    function filterPath(string) {
        return string
        .replace(/^\//,'')
        .replace(/(index|default).[a-zA-Z]{3,4}$/,'')
        .replace(/\/$/,'');
    }

    var locationPath = filterPath(location.pathname);
    var scrollElem = scrollableElement('html', 'body');

    // Any links with hash tags in them (can't do ^= because of fully qualified URL potential)
    $('a[href*=#]').each(function() {

        // Ensure it's a same-page link
        var thisPath = filterPath(this.pathname) || locationPath;
        if (  locationPath == thisPath
            && (location.hostname == this.hostname || !this.hostname)
            && this.hash.replace(/#/,'') ) {

                // Ensure target exists
                var $target = $(this.hash), target = this.hash;
                if (target) {

                    // Find location of target
                    var targetOffset = $target.offset().top;
                    $(this).click(function(event) {

                        // Prevent jump-down
                        event.preventDefault();

                        // Animate to target
                        $(scrollElem).animate({scrollTop: targetOffset}, 2000, function() {

                            // Set hash in URL after animation successful
                            location.hash = target;

                        });
                    });
                }
        }

    });

    // Use the first element that is "scrollable"  (cross-browser fix?)
    function scrollableElement(els) {
        for (var i = 0, argLength = arguments.length; i <argLength; i++) {
            var el = arguments[i],
            $scrollElement = $(el);
            if ($scrollElement.scrollTop()> 0) {
                return el;
            } else {
                $scrollElement.scrollTop(1);
                var isScrollable = $scrollElement.scrollTop()> 0;
                $scrollElement.scrollTop(0);
                if (isScrollable) {
                    return el;
                }
            }
        }
        return [];
    }

});
