我是初学者,需要一些帮助。我使用此 W3Schools 脚本在我的 Shopify 网站上复制折扣代码。

(这与 W3Schools 的代码相同:)
<!DOCTYPE html>

<head>
<meta name="viewport" content="width=device-width, initial-scale=1">

.tooltip {
position: relative;
display: inline-block;
}
.tooltip .tooltiptext {
visibility: hidden;
width: 140px;
background-color: #555;

text-align: center;
border-radius: 6px;
padding: 5px;
position: absolute;
z-index: 1;
bottom: 150%;
left: 50%;
margin-left: -75px;

}
.tooltip .tooltiptext::after {
content: "";
position: absolute;
top: 100%;
left: 50%;
margin-left: -5px;
border-width: 5px;
border-style: solid;
border-color: #555 transparent transparent transparent;
}
.tooltip:hover .tooltiptext {
visibility: visible;
opacity: 1;
}
</style>
</head>
<body>
<p>Click on the button to copy the text from the text field. Try to paste the text (e.g. ctrl+v) afterwards in a different window, to see the effect.</p>
<input type="text" value="Hello World" id="myInput">
<div class="tooltip">
<button onclick="myFunction()" onmouseout="outFunc()">
<span class="tooltiptext" id="myTooltip">Copy to clipboard</span>
Copy text
</button>
</div>
<script>
function myFunction() {
var copyText = document.getElementById("myInput");
copyText.select();
copyText.setSelectionRange(0, 99999);
navigator.clipboard.writeText(copyText.value);
var tooltip = document.getElementById("myTooltip");
tooltip.innerHTML = "Copied: " + copyText.value;
}
function outFunc() {
var tooltip = document.getElementById("myTooltip");
tooltip.innerHTML = "Copy to clipboard";
}
</script>
</body>
</html>
我已经设置得很好,但遇到了问题。单击“复制”时,输入字段边框会变为粗体或变宽,文本会变为白色并以蓝色突出显示。由于某种原因,在我的网站上,它在输入字段/边框周围添加了第二个灰色边框,并且文本保持黑色并带有灰色突出显示。
无论我在样式中或在底部的脚本中尝试使用CSS。我无法在不弄乱其他内容的情况下对此单击后边框和突出显示进行任何更改。
我在代码中没有看到任何控制它的内容。
有什么想法吗?
再次强调,无论我在样式中还是在底部的脚本中尝试使用 CSS。我无法在不弄乱其他内容的情况下对此单击后边框和突出显示进行任何更改。
此问题的解决方案是使用 JavaScript 代码取消选择它。您可以使用
window.getSelection().removeAllRanges();
取消选择输入框。只需使用your-input-id.blur();
。
