Hoe OM - Tabopskrifte
Leer hoe om oortjieopskrifte met CSS en JavaScript te skep.
Oortjieopskrifte
Klik op die "stad"-knoppies om die toepaslike kopskrif te vertoon:
Tokio
Tokio is die hoofstad van Japan.
Skep wisselbare oortjieopskrifte
Stap 1) Voeg HTML by:
Voorbeeld
<div id="London" class="tabcontent">
<h1>London</h1>
<p>London is the
capital city of England.</p>
</div>
<div id="Paris" class="tabcontent">
<h1>Paris</h1>
<p>Paris is the capital of France.</p>
</div>
<div id="Tokyo" class="tabcontent">
<h1>Tokyo</h1>
<p>Tokyo is the
capital of Japan.</p>
</div>
<div id="Oslo" class="tabcontent">
<h1>Oslo</h1>
<p>Oslo is the capital of Norway.</p>
</div>
<button class="tablink" onclick="openCity('London', this, 'red')" id="defaultOpen">London</button>
<button class="tablink" onclick="openCity('Paris', this,
'green')">Paris</button>
<button class="tablink" onclick="openCity('Tokyo',
this, 'blue')">Tokyo</button>
<button class="tablink" onclick="openCity('Oslo',
this, 'orange')">Oslo</button>
Skep knoppies om spesifieke oortjie-inhoud oop te maak. Alle <div>-elemente met class="tabcontent"
is by verstek versteek (met CSS & JS). Wanneer die gebruiker op 'n knoppie klik - sal dit die oortjie-inhoud oopmaak wat by hierdie knoppie "pas".
Stap 2) Voeg CSS by:
Stileer die knoppies en die oortjie-inhoud:
Voorbeeld
/* Style the tab buttons */
.tablink {
background-color: #555;
color: white;
float: left;
border: none;
outline: none;
cursor: pointer;
padding: 14px 16px;
font-size: 17px;
width: 25%;
}
/* Change background color of buttons on hover */
.tablink:hover {
background-color: #777;
}
/* Set default styles for tab content */
.tabcontent
{
color: white;
display: none;
padding: 50px;
text-align: center;
}
/* Style
each tab content individually */
#London {background-color:red;}
#Paris {background-color:green;}
#Tokyo {background-color:blue;}
#Oslo {background-color:orange;}
Stap 3) Voeg JavaScript by:
Voorbeeld
function openCity(cityName, elmnt, color) {
// Hide all
elements with class="tabcontent" by default */
var i,
tabcontent, tablinks;
tabcontent =
document.getElementsByClassName("tabcontent");
for (i =
0; i < tabcontent.length; i++) {
tabcontent[i].style.display = "none";
}
// Remove the background color of all tablinks/buttons
tablinks = document.getElementsByClassName("tablink");
for (i = 0; i < tablinks.length; i++) {
tablinks[i].style.backgroundColor = "";
}
// Show the specific tab content
document.getElementById(cityName).style.display = "block";
// Add the specific color to the button used to open the tab content
elmnt.style.backgroundColor = color;
}
// Get the element with id="defaultOpen"
and click on it
document.getElementById("defaultOpen").click();
