單擊按鈕時如何添加數值？例如，如果我單擊 100,000 兩次，則輸入中將輸入 200,000。
$(document).ready(function() {
$('#myform button').on('click', function() {
$('#cvalue').val($(this).val());
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<div class="box">
<form id="myform">
<div class="inputdiv">
<input type="text" id="cvalue" class="money">
</div>
<button class="button1" type="button" value="100,000">100,000</button>
<button class="button1" type="button" value="200,000">200,000</button>
<button class="button1" type="button" value="300,000">300,000</button>
<button class="button1" type="button" value="500,000">500,000</button>
<button class="button1" type="button" value="1,000,000">1,000,000</button>

const fmt = new Intl.NumberFormat('en-US', { minimumFractionDigits: 0, maximumFractionDigits: 0 });
$(document).ready(function() {
const $cvalue = $('#cvalue');
$('#myform .button1').on('click', function() {
const val = $(this).val().replace(/\D/g, "") $cvalue.val().replace(/\D/g, "")
$cvalue.val(fmt.format(val));
});
