Question

请问我的JS代码出了什么问题，为什么按钮按下去没反应？

<style type="text/css">
table{
border-collapse: collapse;
}
td{
border:1px silver solid;
padding:5px;
font-size: 12px;
}
input{
width: 80px;
}
</style>
<script type="text/javascript">
function converToNumbers(id){
return parseFloat(document.getElementById(id).value);
}
function totalmoney(){
var money=converToNumbers("money");
var years=converToNumbers("years");
var addition=converToNumbers("addition");
var rate=converToNumbers("rate");
rate/=100;
var sum_money=money+(years-1)*addition;
var firstyear=money+money*(1+rate);
var sum=firstyear;
for(int i=1;i<years;i++){
sum+=addition;
sum*=1+rate;
}
document.getElementById("sum_money").value=sum_money;
document.getElementById("sum_profit").value=sum-sum_money;
document.getElementById("moneyAndProfit").value=sum;
}
</script>

Answer 1

JS哪来的int类型的变量 把init i 改成var i

for(int i=1;i<years;i++)

Answer 2

for(int i=1;i<years;i++)你这样写是会报错的，编不过。改成for(var i=1;i<years;i++)即可
