HTML DOM Dokument querySelectorAll()

Voorbeeld

Kies alle elemente met class="example":

document.querySelectorAll(".example");

Meer voorbeelde hieronder.


Definisie en gebruik

Die querySelectorAll()metode gee alle elemente terug wat by 'n CSS-keurder(s) pas.

Die querySelectorAll()metode gee 'n NodeList terug .

Die querySelectorAll()metode gooi 'n SYNTAX_ERR-uitsondering as die kieser(s) ongeldig is


HTML DOM NodeList / HTMLCollection

Die verskille tussen 'n HTML-versameling en 'n nodelys

'n NodeList en 'n HTMLCollection is albei skikking-agtige versamelings (lyste) van nodusse (elemente) wat uit 'n dokument onttrek is. Die nodusse kan verkry word deur indeksnommers. Die indeks begin by 0.

Albei voorwerpe het 'n lengte- eienskap wat die aantal elemente in die lys terugstuur.

'n HTML-versameling is 'n lewendige versameling : As jy 'n <li>-element by 'n lys in die DOM voeg, sal die lys in die HTML-versameling ook verander.

'n NodeList is 'n statiese versameling : As jy 'n <li> element by 'n lys in die DOM voeg, sal die lys in NodeList nie verander nie.

Die getElementsByClassName()en getElementsByTagName() metodes gee 'n HTMLCollection terug.

Die querySelector()en querySelectorAll() metodes gee 'n NodeList terug.

For multiple selectors, separate each selector with a comma (See "More Examples").

Terugkeerwaarde

Meer voorbeelde

Voeg 'n agtergrondkleur by die eerste <p>-element:

const nodeList= document.querySelectorAll("p");
nodeList[0].style.backgroundColor = "red"; 

Voeg 'n agtergrondkleur by die eerste <p>-element met class="example":

const nodeList = document.querySelectorAll("p.example");
nodeList[0].style.backgroundColor = "red"; 

Aantal elemente met class="example":

let numb = document.querySelectorAll(".example").length;

Stel die agtergrondkleur van alle elemente met class="example":

const nodeList = document.querySelectorAll(".example");
for (let i = 0; i < nodeList.length; i++) {
  nodeList[i].style.backgroundColor = "red";
}

Stel die agtergrondkleur van alle <p>-elemente:

let nodeList = document.querySelectorAll("p");
for (let i = 0; i < nodeList.length; i++) {
  nodeList[i].style.backgroundColor = "red";
}

Stel die grens van alle <a>-elemente met 'n "teiken"-kenmerk:

const nodeList = document.querySelectorAll("a[target]");
for (let i = 0; i < nodeList.length; i++) {
  nodeList[i].style.border = "10px solid red";
}

Stel die agtergrondkleur van elke <p>-element waar die ouer 'n <div>-element is:

const nodeList = document.querySelectorAll("div > p");
for (let i = 0; i < nodeList.length; i++) {
  nodeList[i].style.backgroundColor = "red";
}

Stel die agtergrondkleur van alle <h3>-, <div>- en <span>-elemente:

const nodeList = document.querySelectorAll("h3, div, span");
for (let i = 0; i < nodeList.length; i++) {
  nodeList[i].style.backgroundColor = "red";
}
