PROSAGA码农传奇-jqueryMobile-JQueryMobile中的弹出/工具提示位置

<div class =“post-text”itemprop =“text”>
  <P>
    正如问题评论中所讨论的，本机/香草Javascript工具提示，可完全自定义。直观，即使我自己这么说。这是现场演示：

<h2>Light-weight Tooltip by FC</h2>

<p>The <span class="tool">WHO<span class="tip">World Health Organization</span></span> was established in 1948.</p>

<p>
        It is part of the
        <span class="tool">UN
            <span class="tip">United Nations, <br>the successor of the <br>League of Nations</span>
        </span>,
        which was established in 1945.
    </p>

<p>Explanation and 'minds':</p>

<ul>
        <li>The method consists of local nested spans ('tools' with 'tips' inside), positioned relative-absolute.</li>
        <li>If the same tips are to be used several times throughout the page or website, the tip spans can be populated centrally with Javascript or server-side scripting.</li>
        <li>In the current code the width of the tips is set to <i>auto</i>, and controlled with &lt;br&gt;s in the tip text. Change to fixed width as desired.</li>
        <li>With the current code tablet users must tap (= <i>onclick</i>) rather than press-hold (= <i>onmousedown</i>). It is assumed that that is the intuitive thing most tablet users do, but it can be changed to press-hold.</li>
        <li>The HTML is valid and the code also works in IE8.</li>
        <li>It is said that <i>getElementsByClassName(class)</i> returns a dynamic node list, whereas <i>querySelectorAll(.class)</i> would return a static one. That would make the latter unsuited for dynamically updated elements/sections. Also, it is said to be slower/require more CPU power than the first. However, <i>querySelectorAll(.class)</i> is supported by IE8 (not 7). Mind the dot.</li>
        <li>For the sake of completeness: IE9 does not form a border-radius when the element has no declared border, or a border-width of 0.</li>
    </ul>
