Question

我有图像，当鼠标悬停时我想要一个div，但我不希望它在onmouseout上。我编写了代码并且它有效，但它闪烁了。这是代码：

<div id="div" style="opacity:0.6; background-color:#2c3e50; width:136px; height:163px; z-index:199; position:absolute; vertical-align:top; font-size:120px; text-align:center; color:White; display:none;">1</div>
<img alt="ברק לוי" src="" style="background-color:red; height:163px; width:136px" onmouseover="picture(true)" onmouseout="picture(false)"/>

function picture(bool) {
    if (bool) {
        document.getElementById("div").style.display = "block";
    }
    else if (bool==false) {
        document.getElementById("div").style.display = "none";
    }
}

jsBin 我该如何解决？

Answer 1

只需将onmouseover="picture(true)" onmouseout="picture(false)添加到div div。

Answer 2

因为您需要在onmouseout

上使用div事件

<div id="div" style="opacity:0.6; background-color:#2c3e50; width:136px; height:163px; z-index:199; position:absolute; vertical-align:top; font-size:120px; text-align:center; color:White; display:none;" onmouseout="picture(false)">1</div>

<img alt="ברק לוי" src="" style="background-color:red; height:163px; width:136px" onmouseover="picture(true)"/>

function picture(bool) {
    if (bool) {
        document.getElementById("div").style.opacity = "0.6";
    }
    else {
        document.getElementById("div").style.opacity = "0.0";
    }
}

试试这个。闪烁的原因在于，当您设置“显示：无”时，它不存在，并且“鼠标输出”被触发。将不透明度设置为0.0时，它仍然是不可见的，但鼠标输出不会触发。

Div闪烁onmouseover，onmouseout
