[英]HTML tabs not showing in webform (ASP.NET)
我正在使用html-tab视图,其中选项卡被CSS隐藏,并且仅由JavaScript函数可见。 但是它不适用于ASP.NET的Web表单。
它只是立即显示,并在半秒内消失。
我从这里复制。
代码是:
<%@ Page Title="" Language="C#" MasterPageFile="~/MASTER/MASTER.Master" AutoEventWireup="true" CodeBehind="CREATE_USER.aspx.cs" Inherits="CRM_CAPSULE.MASTER.WebForm2" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<style>
body {font-family: "Lato", sans-serif;}
/* Style the tab */
div.tab {
overflow: hidden;
border: 1px solid #ccc;
background-color: #f1f1f1;
}
/* Style the buttons inside the tab */
div.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 */
div.tab button:hover {
background-color: #ddd;
}
/* Create an active/current tablink class */
div.tab button.active {
background-color: #ccc;
}
/* Style the tab content */
.tabcontent {
display: none;
padding: 6px 12px;
-webkit-animation: fadeEffect 1s;
animation: fadeEffect 1s;
}
/* Fade in tabs */
@-webkit-keyframes fadeEffect {
from {opacity: 0;}
to {opacity: 1;}
}
@keyframes fadeEffect {
from {opacity: 0;}
to {opacity: 1;}
}
</style>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<h3>Fade in Tabs</h3>
<div id="tabs" class="tab">
<button class="tablinks" onclick="openCity(event, 'London')">London</button>
<button class="tablinks" onclick="openCity(event, 'Paris')">Paris</button>
<button class="tablinks" onclick="openCity(event, 'Tokyo')">Tokyo</button>
</div>
<div id="tabs">
<div id="London" class="tabcontent">
<h3>London</h3>
<p>London is the capital city of England.</p>
</div>
<div id="Paris" class="tabcontent">
<h3>Paris</h3>
<p>Paris is the capital of France.</p>
</div>
<div id="Tokyo" class="tabcontent">
<h3>Tokyo</h3>
<p>Tokyo is the capital of Japan.</p>
</div>
</div>
<script>
function openCity(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";
}
</script>
</asp:Content
您的CSS和JavaScript代码可以正常工作。
一种
<style> body {font-family: "Lato", sans-serif;} /* Style the tab */ div.tab { overflow: hidden; border: 1px solid #ccc; background-color: #f1f1f1; } /* Style the buttons inside the tab */ div.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 */ div.tab button:hover { background-color: #ddd; } /* Create an active/current tablink class */ div.tab button.active { background-color: #ccc; } /* Style the tab content */ .tabcontent { display: none; padding: 6px 12px; -webkit-animation: fadeEffect 1s; animation: fadeEffect 1s; } /* Fade in tabs */ @-webkit-keyframes fadeEffect { from {opacity: 0;} to {opacity: 1;} } @keyframes fadeEffect { from {opacity: 0;} to {opacity: 1;} } </style> <h3>Fade in Tabs</h3> <div id="tabs" class="tab"> <button class="tablinks" onclick="openCity(event, 'London')">London</button> <button class="tablinks" onclick="openCity(event, 'Paris')">Paris</button> <button class="tablinks" onclick="openCity(event, 'Tokyo')">Tokyo</button> </div> <div id="tabs"> <div id="London" class="tabcontent"> <h3>London</h3> <p>London is the capital city of England.</p> </div> <div id="Paris" class="tabcontent"> <h3>Paris</h3> <p>Paris is the capital of France.</p> </div> <div id="Tokyo" class="tabcontent"> <h3>Tokyo</h3> <p>Tokyo is the capital of Japan.</p> </div> </div> <script> function openCity(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"; } </script> </script>
asp:Content可能有问题...
从浏览器检查页面,并确保CSS和JS代码在页面上的正确位置。
首先,将第二个id =“ tabs”替换为class =“ tab”,因为您不能使用重复的ID。 并尝试此脚本。
var tabArea = ".tab .tablinks",
tabContent = '.tabcontent';
$(tabArea).add(tabContent).each(function () {
$(this).siblings(':first-child').addClass('active');
});
$(tabArea).on('click', function(){
$(this).each(function(){
var tabIndex = $(this).index();
$(this).siblings().removeClass('active');
$(this).parent('.tab').next(".tab")
.find(tabContent).removeClass('active');
$(this).addClass('active');
$(this).parent('.tab').next(".tab")
.find(tabContent).eq(tabIndex).addClass('active');
})
});
还添加以下CSS
.tabcontent.active {
display: block;
}
