我有以下代码。以格式编号为货币的Javascript
<select id="cage_options">
<option>Please select</option>
<option value="2,63330">option1</option>
<option value="3,13300">option2</option>
<option value="4,2000.00">option3</option>
</select>
<input id="cage_labor_estimate" disabled>
<script>
function format(n) {
return n.toFixed(2).replace(/(\d)(?=(\d{3})+\.)/g, "$1,");
}
document.getElementById("cage_options").addEventListener("change", cageOptionFunction);
function cageOptionFunction() {
select=document.getElementById('cage_options').value.split(',');
cage_option = select[1];
document.getElementById("cage_labor_estimate").value = format(cage_option);
}
</script>
我试图在禁用输入框中输入输出格式在当前的格式,但出现以下错误:
TypeError: n.toFixed is not a function. (In 'n.toFixed(2)', 'n.toFixed' is undefined)
谁能帮助?
感谢,
