HTML DOM Element klasnaam

❮ Die elementvoorwerp

Voorbeeld

Stel die klaskenmerk vir 'n element:

element.className = "myStyle";

Kry die klaskenmerk van "myDIV":

let value = document.getElementById("myDIV").className;

Wissel tussen twee klasname:

if (element.className == "myStyle") {
  element.className = "newStyle";
} else {
  element.className = "myStyle";
}

Meer voorbeelde hieronder.


Definisie en gebruik

Die classNameeienskap stel of gee 'n element se klaskenmerk terug.


Sintaksis

Gee die className-eienskap terug:

HTMLElementObject.className

Stel die className-eienskap:

HTMLElementObject.className = class

Eiendomswaardes

Value Description
class The class name(s) of an element.
Separate multiple classes with spaces, like "test demo".


Terugkeerwaarde

Type Description
StringThe class, or a space-separated list of classes, of an element

Meer voorbeelde

Kry die klaskenmerk van die eerste <div>-element (indien enige):

let value = document.getElementsByTagName("div")[0].className;

Kry 'n klaskenmerk met veelvuldige klasse:

<div id="myDIV" class="myStyle test example">
<p>I am myDIV.</p>
</div>
let value = document.getElementById("myDIV").className;

Oorskryf 'n bestaande klaskenmerk met 'n nuwe een:

element.className = "newClassName";

Om nuwe klasse by te voeg, sonder om bestaande waardes te oorskryf, voeg 'n spasie en die nuwe klasse by:

element.className += " class1 class2";

as "myDIV" 'n "myStyle"-klas het, verander die lettergrootte:

const elem = document.getElementById("myDIV");

if (elem.className == "mystyle") {
  elem.style.fontSize = "30px";
}

As jy 50 pixels van die bokant van hierdie bladsy af blaai, word die klas "toets" bygevoeg:

window.onscroll = function() {myFunction()};

function myFunction() {
  if (document.body.scrollTop > 50) {
    document.getElementById("myP").className = "test";
  } else {
    document.getElementById("myP").className = "";
  }
}
