Hoe OM - Lengte-omskakelaar
Leer hoe om 'n lengte-omskakelaar met HTML en JavaScript te skep.
Lengte-omskakelaar
Tik 'n waarde in enige van die velde om tussen lengtemetings om te skakel:
Skep 'n lengte-omskakelaar
Skep 'n invoerelement wat 'n waarde van een lengtemeting na 'n ander kan omskakel.
Stap 1) Voeg HTML by:
Voorbeeld - Voete tot Meter
<p>
<label>Feet</label>
<input id="inputFeet" type="number" placeholder="Feet"
oninput="lengthConverter(this.value)" onchange="lengthConverter(this.value)">
</p>
<p>cm: <span id="outputMeters"></span></p>
Stap 2) Voeg JavaScript by:
Voorbeeld - Voete tot Meter
/* When the input field receives input, convert the value from feet to meters */
function lengthConverter(valNum) {
document.getElementById("outputMeters").innerHTML = valNum / 0.0022046;
}
