Saya ingin mendapatkan nilai yang dipilih dari sekelompok tombol radio.
Inilah HTML saya:
<div id="rates">
<input type="radio" id="r1" name="rate" value="Fixed Rate"> Fixed Rate
<input type="radio" id="r2" name="rate" value="Variable Rate"> Variable Rate
<input type="radio" id="r3" name="rate" value="Multi Rate" checked="checked"> Multi Rate
</div>
Ini .js saya:
var rates = document.getElementById('rates').value;
var rate_value;
if(rates =='Fixed Rate'){
rate_value = document.getElementById('r1').value;
}else if(rates =='Variable Rate'){
rate_value = document.getElementById('r2').value;
}else if(rates =='Multi Rate'){
rate_value = document.getElementById('r3').value;
}
document.getElementById('results').innerHTML = rate_value;
Saya terus terdefinisi.
.checked
<form></form>
wadah.
$("input[type='radio'][name='rate']:checked").val();
