HTML DOM nodeValue Eiendom

Element Voorwerp

Voorbeeld

Kry die noduswaarde van die eerste <button>-element in die dokument:

var x = document.getElementsByTagName("BUTTON")[0].childNodes[0].nodeValue;

Meer "Probeer dit self" voorbeelde hieronder.


Definisie en gebruik

Die nodeValue-eienskap stel of gee die noduswaarde van die gespesifiseerde nodus terug.

As die nodus 'n elementnodus is, sal die nodeValue-eienskap nul terugstuur.

Let wel: As jy die teks van 'n element wil terugstuur, onthou dat teks altyd binne 'n Teksnodus is, en jy sal die Teksnodus se noduswaarde ( element .childNodes[0].nodeValue) moet terugstuur.

Vir ander nodustipes sal die nodeValue-eienskap verskillende waardes vir verskillende nodustipes terugstuur.

Wenk: 'n Alternatief vir die nodeValue-eienskap kan die textContent- eienskap wees.


Blaaierondersteuning

Property
nodeValue Yes Yes Yes Yes Yes

Sintaksis

Gee die noduswaarde terug:

node.nodeValue

Stel die noduswaarde:

node.nodeValue = value

Eiendomswaardes

Value Description
value  Specifies the node value of the specified node


Tegniese besonderhede

Terugkeerwaarde: 'n String, wat die waarde van die nodus verteenwoordig.

Moontlike waardes:

  • Wys nul vir element nodusse en dokument nodusse
  • Wys die waarde van die kenmerk vir kenmerknodes
  • Wys die inhoud vir teksnodes
  • Wys die inhoud vir kommentaarnodes
DOM weergawe Kernvlak 1 Node-objek

Meer voorbeelde

Voorbeeld

Kry die nodus naam, nodus waarde en die node tipe van die <div> element se eerste kind node:

<div id="myDIV">This is a div element.</div>

<script>
var x = document.getElementById("myDIV").firstChild;
var txt = "";
txt += "The node name: " + x.nodeName + "<br>";
txt += "The node value: " + x.nodeValue + "<br>";
txt += "The node type: " + x.nodeType;
</script>
