javascript - 如何暂时禁用 div 的悬停？

Question

我正在制作一个网页。我创建了一个弹出窗口，当我将鼠标悬停在 div 上时，弹出窗口会打开，如果没有，它会关闭。我想创建一个功能，如果我单击 div，弹出窗口将保持打开状态而无需悬停。我该怎么办？提前致谢。

我有这个代码:

HTML:

<div class="password-lost-tooltip" onclick="blockTooltip()">Lost password?
        <span class="password-lost-tooltiptext" id="lostpasswordtooltip">LOL</span>
</div>

CSS:

.password-lost-tooltip {
    position: relative;
    display: inline-block;
    position: fixed;
    top: 55px;
    left: 380px;
    font-family: 'Nunito', sans-serif;
    font-size: 15;
    text-decoration: none;
    transition-duration: 0.3s;
    color: grey;
}

.password-lost-tooltip:hover {
    color: black;
    cursor: pointer;
}

.password-lost-tooltip .password-lost-tooltiptext {
    visibility: hidden;
    width: 120px;
    background-color: #555;
    color: #fff;
    text-align: center;
    padding: 5px 0;
    border-radius: 6px;

    position: fixed;
    top: 49px;
    left: 610px;
    margin-left: -60px;

    opacity: 0;
    transition: opacity 0.3s;
}

.password-lost-tooltip .password-lost-tooltiptext::after {
    content: "";
    position: fixed;
    transform: rotate(90deg);
    top: 57.5px;
    left: 542.5px;
    margin-left: -5px;
    border-width: 6px;
    border-style: solid;
    border-color: #555 transparent transparent transparent;
}

.password-lost-tooltip:hover .password-lost-tooltiptext {
    visibility: visible;
    opacity: 1;
}

您可以使用 onClick 和 onBlur 事件来设置或删除 div 上的类，然后将其添加到 css 以控制可见性。

请检查这个运行示例:

function blockTooltip () {
  document.querySelector('.password-lost-tooltip').classList.add('showTip');
}

function hideTooltip () {
  document.querySelector('.password-lost-tooltip').classList.remove('showTip');
}

.password-lost-tooltip {
    position: relative;
    display: inline-block;
    position: fixed;
    top: 55px;
    left: 380px;
    font-family: 'Nunito', sans-serif;
    font-size: 15;
    text-decoration: none;
    transition-duration: 0.3s;
    color: grey;
}

.password-lost-tooltip:hover {
    color: black;
    cursor: pointer;
}

.password-lost-tooltip .password-lost-tooltiptext {
    visibility: hidden;
    width: 120px;
    background-color: #555;
    color: #fff;
    text-align: center;
    padding: 5px 0;
    border-radius: 6px;

    position: fixed;
    top: 49px;
    left: 610px;
    margin-left: -60px;

    opacity: 0;
    transition: opacity 0.3s;
}

.password-lost-tooltip .password-lost-tooltiptext::after {
    content: "";
    position: fixed;
    transform: rotate(90deg);
    top: 57.5px;
    left: 542.5px;
    margin-left: -5px;
    border-width: 6px;
    border-style: solid;
    border-color: #555 transparent transparent transparent;
}

.password-lost-tooltip:hover .password-lost-tooltiptext {
    visibility: visible;
    opacity: 1;
}

.password-lost-tooltip.showTip .password-lost-tooltiptext {
    visibility: visible;
    opacity: 1;
}

<div class="password-lost-tooltip" tabindex="0"
     onclick="blockTooltip()" onblur="hideTooltip()">Lost password?
        <span class="password-lost-tooltiptext" id="lostpasswordtooltip">LOL</span>
</div>
