我是一個年輕的開發人員在asp.net mvc,現在我試圖做一個簡單的計算器,計算出用戶輸入的值。顯示結果從控制器的視圖在asp.net mvc c#
這是我的MVC模式:
public class MoneyInstallments
{
[Required(ErrorMessage="The price is required.")]
public double price { get; set; }
[Required(ErrorMessage = "The duration is required.")]
public int duration { get; set; }
public double interestRate = 0.029;
public double total_interest { get; set; }
public double total_money { get; set; }
public double total_money_month { get; set; }
}
控制器:
public ActionResult Index()
{
return View();
}
[HttpPost]
public ActionResult Index(FormCollection frm)
{
string price_str = frm["price"].ToString();
string duration_str = frm["duration"].ToString();
double price;
double duration;
try
{
price = Convert.ToDouble(price_str);
duration = Convert.ToDouble(duration_str);
double interestRate = 0.029;
double total_interest = interestRate * duration;
double total_money = total_interest + price;
double total_money_month = total_money/duration;
}
catch (FormatException)
{
Response.Write("Unable to caculate"+price_str);
}
catch (OverflowException)
{
Response.Write("Unable to caculate" + price_str);
}
return View();
}
的觀點:
<% Html.BeginForm(); %>
<fieldset>
<legend>Money Information</legend>
<table>
<tr>
<td>Product Price:</td>
<td>:</td>
<td>
<%: Html.TextBoxFor(m => m.price, new { id = "price", name = "price"})%> <!-- user can type only 50 char of the string -->
<%: Html.ValidationMessageFor(m => m.price)%>
</td>
</tr>
<tr>
<td>Interest per month</td>
<td>:</td>
<td>2.9%</td>
</tr>
<tr>
<td>Duration</td>
<td>:</td>
<td>
<%: Html.TextBoxFor(m => m.duration, new {id="duration", name="duration"}) %>
<%: Html.ValidationMessageFor(m => m.duration) %>
</td>
</tr>
<tr>
<td colspan="3" align="right"><input type="submit" value="Calculate"id="btnCalculate"/></td>
</tr>
<tr>
<td>Monthly Pay is</td>
<td>:</td>
<td><div id="result"></div></td>
</tr>
</table>
</fieldset>
<% Html.EndForm(); %>
我想顯示從我的控制器total_money_month到中我的意見,但我知道這個想法。任何人都可以告訴我。
使用ViewBag有錯誤:它不會在我的當前上下文包含。 – Nothing
你使用MVC3嗎?如果沒有,您可以使用ViewData代替。 –
