Skrip -asinkroniseer Eiendom

❮ Skripobjek

Voorbeeld

Vind uit of 'n skrip asynchronies uitgevoer is sodra dit beskikbaar was:

var x = document.getElementById("myScript").async

Definisie en gebruik

Die async-eienskap stel of gee terug of 'n skrip asynchronies uitgevoer moet word sodra dit beskikbaar is, of nie.

Hierdie eienskap weerspieël die async-kenmerk van die <script>-merker.

Let wel: Die async-kenmerk is slegs vir eksterne skrifte (en moet slegs gebruik word as die src-kenmerk teenwoordig is).

Let wel: Daar is verskeie maniere waarop 'n eksterne skrip uitgevoer kan word:

  • As asinkronisering teenwoordig is: Die skrip word asynchronies met die res van die bladsy uitgevoer (die skrip sal uitgevoer word terwyl die bladsy voortgaan met die ontleding)
  • As asinkronisering nie teenwoordig is nie en uitstel teenwoordig is: Die skrip word uitgevoer wanneer die bladsy klaar geparseer het
  • As nóg asinc of uitstel teenwoordig is: Die skrip word dadelik gehaal en uitgevoer voordat die blaaier voortgaan om die bladsy te ontleed

Blaaierondersteuning

Die nommers in die tabel spesifiseer die eerste blaaierweergawe wat die eiendom ten volle ondersteun.

Property
async Yes 10.0 Yes Yes Yes


Sintaksis

Gee die asinc-eienskap terug:

scriptObject.async

Stel die asinc-eienskap:

scriptObject.async = true|false

Eiendomswaardes

Value Description
true|false Specifies whether a script should be executed asynchronously as soon as it is available, or not
  • true - The script will be executed asynchronously as soon as it is available
  • false - The script will not be executed asynchronously as soon as it is available

Tegniese besonderhede

Terugkeerwaarde: 'n Boolean, gee waar as die skrip asynchronies uitgevoer word sodra dit beskikbaar is, anders gee dit vals terug
