onfocusin gebeurtenis

Voorbeeld

Voer 'n JavaScript uit wanneer 'n invoerveld besig is om fokus te kry:

<input type="text" onfocusin="myFunction()">

Meer "Probeer dit self" voorbeelde hieronder.


Definisie en gebruik

Die onfokusingebeurtenis vind plaas wanneer 'n element op die punt is om fokus te kry.

Wenk: Die onfocusin-geleentheid is soortgelyk aan die onfokus -gebeurtenis. Die belangrikste verskil is dat die fokusgebeurtenis nie borrel nie. Daarom, as jy wil uitvind of 'n element of sy kind die fokus kry, moet jy die onfocusin-gebeurtenis gebruik.

Wenk: Die onfokusgebeurtenis is die teenoorgestelde van die onfokusuitgebeurtenis .


Blaaierondersteuning

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

Event
onfocusin Yes Yes 52.0 Yes Yes

Let wel: Die onfocusin-geleentheid sal dalk nie werk soos verwag in Chrome, Safari en Opera 15+ deur die JavaScript HTML DOM-sintaksis te gebruik nie. Dit moet egter werk as 'n HTML-kenmerk en deur die addEventListener()-metode te gebruik (Sien sintaksisvoorbeelde hieronder).



Sintaksis

In HTML:

<element onfocusin="myScript">

In JavaScript (werk dalk nie soos verwag in Chrome, Safari en Opera 15+ nie):

object.onfocusin = function(){myScript};

In JavaScript, gebruik die addEventListener() metode:

object.addEventListener("focusin", myScript);

Let wel: Die addEventListener() metode word nie in Internet Explorer 8 en vroeër weergawes ondersteun nie.


Tegniese besonderhede

borrels: Ja
Kanselleerbaar: Geen
Soort gebeurtenis: FokusGebeurtenis
Ondersteunde HTML-etikette: ALLE HTML-elemente, BEHALWE: <basis>, <bdo>, <br>, <kop>, <html>, <iframe>, <meta>, <param>, <skrif>, <styl> en <titel>
DOM weergawe: Vlak 2-geleenthede

Meer voorbeelde

Voorbeeld

Gebruik "onfocusin" saam met die "onfocusout" gebeurtenis:

<input type="text" onfocusin="focusFunction()" onfocusout="blurFunction()">

Voorbeeld

Gebeurtenisdelegering: stel die useCapture- parameter van addEventListener() op waar (vir fokus en vervaag):

<form id="myForm">
  <input type="text" id="myInput">
</form>

<script>
var x = document.getElementById("myForm");
x.addEventListener("focus", myFocusFunction, true);
x.addEventListener("blur", myBlurFunction, true);

function myFocusFunction() {
  document.getElementById("myInput").style.backgroundColor = "yellow";
}

function myBlurFunction() {
  document.getElementById("myInput").style.backgroundColor = "";
}
</script>

Voorbeeld

Gebeurtenisdelegering: gebruik die focusin gebeurtenis:

<form id="myForm">
  <input type="text" id="myInput">
</form>

<script>
var x = document.getElementById("myForm");
x.addEventListener("focusin", myFocusFunction);
x.addEventListener("focusout", myBlurFunction);

function myFocusFunction() {
  document.getElementById("myInput").style.backgroundColor = "yellow";
}

function myBlurFunction() {
  document.getElementById("myInput").style.backgroundColor = "";
}
</script>
