表单onsubmit不起作用

Question

@model MVC_STORE.Models.Product

@{
    Layout = null;
}

<!DOCTYPE html>
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/jquery.validate.js"></script>
<script src="~/Scripts/jquery.validate.unobtrusive.js"></script>

<head>
    <meta name="viewport" content="width=device-width" />
    <title>AddProduct</title>
</head>
<body>
    <div>
        <form id="formAdd" onsubmit=" return SendData(); return false;">
            <table>
                <tr>
                    <td>Serial number:</td>
                    <td>@Html.TextBoxFor(m => m.SerialNo) @Html.ValidationMessageFor(m => m.SerialNo)</td>
                </tr>
                <tr>
                    <td>Product name:</td>
                    <td>@Html.TextBoxFor(m => m.Name) @Html.ValidationMessageFor(m => m.Name)</td>
                </tr>
                <tr>
                    <td>Product price:</td>
                    <td>@Html.TextBoxFor(m => m.Price) @Html.ValidationMessageFor(m => m.Price)</td>
                </tr>
                <tr>
                    <td>Product quatity:</td>
                    <td>@Html.TextBoxFor(m => m.Quatity) @Html.ValidationMessageFor(m => m.Quatity)</td>
                </tr>
            </table>
            <input type="submit" id="toAdd" value="Add product" />
        </form>

        @Html.Partial("ProductsTable")

        <script language="javascript">
            function SendData() {
                $("#status").text("Saving product, please wait..");
                var formData = $("#formAdd").serialize();
                $.post("addProduct", formData, BindData);
                $("#status").text("");
            }
        </script>

    </div>
</body>
</html>

the onsubmit doesn't work for some reason, and I've read a lot of posts about it, but none of them helped me in this case. onsubmit出于某种原因无法正常工作，我已经阅读了很多有关它的文章，但是在这种情况下，没有人帮助我。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;

namespace HW_MVC_STORE.Models
{
    public class Product
    {
        [Key]
        [RegularExpression("^[a-zA-Z0-9]+$", ErrorMessage = "Only upper- and lower- case letters and numbers.")]
        [Required]
        [StringLength(5,MinimumLength=5, ErrorMessage = "Please enter 5 characters serial.")]
        public string SerialNo { get; set; }


        [RegularExpression("^[a-zA-Z]+$", ErrorMessage = "Only upper- and lower- case letters")]
        [Required]
        [StringLength(10, MinimumLength=2, ErrorMessage="Please enter between 2 and 10 characters.")]
        public string Name { get; set; }

        [RegularExpression("^[0-9]+$", ErrorMessage = "Integers only")]
        [Required]
        public string Quatity { get; set; }

        [RegularExpression("^([0-9]+[.][0-9]+)|([1-9]+[0-9]*)$", ErrorMessage = "Numbers only, bigger then zero")]
        [Required]
        public string Price { get; set; }
    }
}

I've tried some suggestions from posts, but none of them worked. 我已经尝试了帖子中的一些建议，但是都没有用。

<form id="formAdd" onsubmit="return SendData(); return false;">
<form id="formAdd" onsubmit="return SendData();">
<form id="formAdd" onsubmit="SendData()">

I don't understand why it's even calls the SendData() function, it doesn't suppose to leave the form until all the text-boxes are correctly filed. 我不明白为什么它甚至调用了SendData（）函数，它不打算在所有文本框都正确归档之前就离开表单。

how can I fix it or at least what is wrong with it? 我该如何解决它，或者至少有什么问题呢？

You need: 你需要：

<form id="formAdd" onsubmit="SendData(); return false;">

the function SendData doesn't return a value, thus return SendData(); 函数SendData不返回值，因此return SendData(); doesn't make sense. 没有道理。
not returning false would cause a reload of the page (default action) 不返回false会导致页面重新加载（默认操作）

If the ajax POST in SendData is not working, we need more details on that. 如果SendData的ajax POST无法正常工作，我们需要更多详细信息。
