Styl vertoon Eiendom
Voorbeeld
Stel 'n <div>-element om nie vertoon te word nie:
document.getElementById("myDIV").style.display = "none";
Definisie en gebruik
Die vertoon-eienskap stel of gee die element se vertoontipe terug.
Elemente in HTML is meestal "inlyn" of "blok" elemente: 'n Inlyn element het drywende inhoud aan sy linker- en regterkant. 'n Blokelement vul die hele lyn, en niks kan aan sy linker- of regterkant vertoon word nie.
Die vertoon-eienskap laat die skrywer ook toe om 'n element te wys of te versteek. Dit is soortgelyk aan die sigbaarheidseiendom . As jy egter instel display:none, versteek dit die hele element, terwyl visibility:hiddendit beteken dat die inhoud van die element onsigbaar sal wees, maar die element bly in sy oorspronklike posisie en grootte.
Wenk: As 'n element 'n blokelement is, kan sy vertoontipe ook met die float-eienskap verander word.

Voorbeeld
Verskil tussen die vertooneienskap en die sigbaarheidseienskap:
function demoDisplay() {
document.getElementById("myP1").style.display = "none";
}
function demoVisibility() {
document.getElementById("myP2").style.visibility = "hidden";
}
Voorbeeld
Wissel tussen versteek en wys van 'n element:
function myFunction() {
var x = document.getElementById('myDIV');
if (x.style.display === 'none') {
x.style.display = 'block';
} else {
x.style.display = 'none';
}
}
Voorbeeld
Verskil tussen "inlyn", "blok" en "geen":
function myFunction(x) {
var whichSelected = x.selectedIndex;
var sel = x.options[whichSelected].text;
var elem = document.getElementById("mySpan");
elem.style.display = sel;
}
Voorbeeld
Gee die vertoontipe van 'n <p>-element terug:
alert(document.getElementById("myP").style.display);
