我正在尝试通过ajax提交表单，它可以正常工作，但是没有验证。因此，我已经添加了JQuery验证库并将代码添加到了文档中所述的处理程序中，但是似乎没有执行
cshtml页面：
@{
ViewData["Title"] = "CreateProduct";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h1 class="text-center">Create Product</h1>
<br>
<form method="post" id="formdata" asp-controller="Product" asp-action="UploadProduct">
<div class="form-group">
<p>Please provide a name for your product:</p>
<input type="text" name="Name" required />
</div>
<div class="form-group">
<p>Please provide a price for your product:</p>
<input type="number" name="Price" required />
</div>
<div class="form-group">
<p>Please provide a description for your product:</p>
<input type="text" name="Description" required />
</div>
</form>
<button class="btn btn-primary" id="subBtn">Upload Files</button>
@section scripts
{
<script>
$(function () {
$('#subBtn').click(function (e) {
var formData = $('#formdata').serialize();
$('#formdata').validate({
debug: true,
submitHandler: function () {
$.ajax({
type: 'POST',
url: '/Product/UploadProduct',
data: formData,
success: function (e) {
Toastify({
text: "Product submition successful!",
duration: 3000,
gravity: "bottom", // `top` or `bottom`
position: 'right', // `left`, `center` or `right`
backgroundColor: 'blue',//"linear-gradient(to right, #00b09b, #96c93d)",
stopOnFocus: true, // Prevents dismissing of toast on hover
onClick: function () { } // Callback after click
}).showToast();
$(':input', '#formdata')
.not(':button, :submit, :reset, :hidden')
.val('')
.prop('checked', false)
.prop('selected', false);
}
}).fail(function (e) {
//toastr.error('Product not added');
});
}
});
});
});
</script>
}
并且我已将引用添加到_Layout.cshtml：
<environment include="Development">
<script src="~/lib/jquery/dist/jquery.js"></script>
<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.js"></script>
<script src="~/lib/jquery-validation/dist/jquery.validate.js"></script>
<script src="~/lib/jquery-validation/dist/additional-methods.js"></script>
<script src="~/lib/jquery-validation-unobtrusive/jquery.validate.unobtrusive.js"></script>
</environment>
我想再次补充一下，逻辑是有效的，只是validate（）方法没有执行。
答案 0 :(得分：1)
ALTER FUNCTION [dbo].[UDF_GetNumeric]
(@strAlphaNumeric VARCHAR(256))
RETURNS VARCHAR(256)
AS
BEGIN
DECLARE @intAlpha INT
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric)
BEGIN
WHILE @intAlpha > 0
BEGIN
SET @strAlphaNumeric = STUFF(@strAlphaNumeric, @intAlpha, 1, '' )
SET @intAlpha = PATINDEX('%[^0-9]%', @strAlphaNumeric )
END
END
RETURN ISNULL(@strAlphaNumeric,0)
END
方法仅用于初始化表单上的插件。它不属于提交按钮的单击处理程序内。您应该将.validate()方法移到客户端处理程序之外，并在validate()事件内序列化数据：
submitHandler然后您可以使用<script>
$(function () {
$('#formdata').validate({
submitHandler: function () {
var formData = $('#formdata').serialize();
alert("ad");
$.ajax({
type: 'POST',
url: '/Product/UploadProduct',
data: formData,
success: function (e) {
Toastify({
text: "Product submition successful!",
duration: 3000,
gravity: "bottom", // `top` or `bottom`
position: 'right', // `left`, `center` or `right`
backgroundColor: 'blue',//"linear-gradient(to right, #00b09b, #96c93d)",
stopOnFocus: true, // Prevents dismissing of toast on hover
onClick: function () { } // Callback after click
}).showToast();
$(':input', '#formdata')
.not(':button, :submit, :reset, :hidden')
.val('')
.prop('checked', false)
.prop('selected', false);
}
}).fail(function (e) {
//toastr.error('Product not added');
});
}
});
});
</script>
标签内的“提交”按钮来触发提交：
