如何刪除 HTML / CSS 中選定選項卡的邊框？
[英]How can I remove the border of the selected tab in HTML / CSS?
問題描述
I have the html and css for creating the horizontal tab bar in which I have some classes and a javascript function which bascially changes the tab based on the selection of the specific tab:
function openPage(evt, cityName) { var i, tabcontent, tablinks; tabcontent = document.getElementsByClassName("tabcontent"); for (i = 0; i < tabcontent.length; i++) { tabcontent[i].style.display = "none"; } tablinks = document.getElementsByClassName("tablinks"); for (i = 0; i < tablinks.length; i++) { tablinks[i].className = tablinks[i].className.replace(" active", ""); } document.getElementById(cityName).style.display = "block"; evt.currentTarget.className += " active"; } // Get the element with id="defaultOpen" and click on it document.getElementById("defaultOpen").click();
body { font-family: Arial; } /* Style the tab */.tab { overflow: hidden; border: 1px solid #ccc; background-color: #f1f1f1; } /* Style the buttons inside the tab */.tab button { background-color: inherit; float: left; border: none; outline: none; cursor: pointer; padding: 14px 16px; transition: 0.3s; font-size: 17px; } /* Change background color of buttons on hover */.tab button:hover { background-color: #ddd; } /* Create an active/current tablink class */.tab button.active { background-color: #FFFFFF; border-bottom-color: #FFFFFF; } /* Style the tab content */.tabcontent { display: none; padding: 6px 12px; border: 1px solid #ccc; border-top: none; } /* Style the close button */.topright { float: right; cursor: pointer; font-size: 28px; }.topright:hover { color: red; }
<h2>Tabs</h2> <p>Click on the x button in the top right corner to close the current tab:</p> <div class="tab"> <button class="tablinks" onclick="openPage(event, 'Home')" id="defaultOpen">Home</button> <button class="tablinks" onclick="openPage(event, 'AboutUs')">AboutUs</button> <button class="tablinks" onclick="openPage(event, 'Careers')">Careers</button> </div> <div id="Home" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Home</h3> <p>Home Page.</p> </div> <div id="AboutUs" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>AboutUs</h3> <p>AboutUs page.</p> </div> <div id="Careers" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Careers</h3> <p>Careers Page.</p> </div>
當我運行它時，它工作正常，但在我要刪除的選定選項卡下方有一個下划線。 有誰知道，如何在選定的選項卡下將其刪除？
謝謝

如果我錯了，請告訴我，但你想看看這樣嗎？
<html> <head> <style> body { font-family: Arial; } /* Style the tab */.tab { overflow: hidden; border: 1px solid #ccc; border-bottom: none; background-color: #f1f1f1; } /* Style the buttons inside the tab */.tab button { background-color: inherit; float: left; border: none; outline: none; cursor: pointer; padding: 14px 16px; transition: 0.3s; font-size: 17px; } /* Change background color of buttons on hover */.tab button:hover { background-color: #ddd; } /* Create an active/current tablink class */.tab button.active { background-color: #FFFFFF; border-bottom-color: #FFFFFF; } /* Style the tab content */.tabcontent { display: none; padding: 6px 12px; border: 1px solid #ccc; border-top: none; } /* Style the close button */.topright { float: right; cursor: pointer; font-size: 28px; }.topright:hover { color: red; } </style> </head> <body> <h2>Tabs</h2> <p>Click on the x button in the top right corner to close the current tab:</p> <div class="tab"> <button class="tablinks" onclick="openPage(event, 'Home')" id="defaultOpen">Home</button> <button class="tablinks" onclick="openPage(event, 'AboutUs')">AboutUs</button> <button class="tablinks" onclick="openPage(event, 'Careers')">Careers</button> </div> <div id="Home" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Home</h3> <p>Home Page.</p> </div> <div id="AboutUs" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>AboutUs</h3> <p>AboutUs page.</p> </div> <div id="Careers" class="tabcontent"> <span onclick="this.parentElement.style.display='none'" class="topright">×</span> <h3>Careers</h3> <p>Careers Page.</p> </div> <script> function openPage(evt, cityName) { var i, tabcontent, tablinks; tabcontent = document.getElementsByClassName("tabcontent"); for (i = 0; i < tabcontent.length; i++) { tabcontent[i].style.display = "none"; } tablinks = document.getElementsByClassName("tablinks"); for (i = 0; i < tablinks.length; i++) { tablinks[i].className = tablinks[i].className.replace(" active", ""); } document.getElementById(cityName).style.display = "block"; evt.currentTarget.className += " active"; } // Get the element with id="defaultOpen" and click on it document.getElementById("defaultOpen").click(); </script> </body> </html>

唯一的變化是
.tab {
overflow: hidden;
border: 1px solid #ccc;
border-bottom-color: transparent;
background-color: #f1f1f1;
}
/* Style the buttons inside the tab */
.tab button {
background-color: inherit;
float: left;
border-bottom: 1px solid #ccc;
outline: none;
cursor: pointer;
padding: 14px 16px;
transition: 0.3s;
font-size: 17px;
}

你可以寫這樣的代碼。
elm.style.textDecoration = "none";
頁面刷新更改“選定”選項卡並顯示主選項卡。 如何保持所選標簽完整無缺？
