我有一个代表一个项目的表格。该表单包含一个提交按钮。如果单击提交按钮，则应在这些字段上进行不显眼的验证。
如果验证失败，则不会发生其他任何事情。
如果验证通过，则该项目应添加到 Knockout.js 观察数组集合中。
在这两种情况下，整个过程都应该保留在客户端而不提交给服务器。提交和服务器端验证将在流程的后期进行。
我怎样才能达到预期的效果？
我正在使用带有数据注释的 ASP.Net MVC。我不想在客户端手动复制验证逻辑。
我还应该提到我在同一页面上有几个表格。
这是我到目前为止所做的......
这是我的 ASP.Net MVC 布局文件：

这是我目前正在处理的相关部分的代码（有几个类似的部分将放在同一页面上）：
<form id="AddCrimeForm">
<div class="panel panel-success">
<div class="panel-heading">
<div class="form-horizontal">
<div class="row">
<div class="col-lg-11">Add a crime incident to the list</div>
<div class="col-lg-1">
<button type="submit" class="btn btn-success btn-xs" onclick="addCrime();"><i class="fa fa-plus"></i> Add</button>
</div>
</div>
</div>
</div>
<div class="panel-body">
<div class="form-horizontal">
<div class="row">
<div class="col-lg-6">
<input data-val="true" data-val-number="The field Id must be a number." data-val-required="The Id field is required." id="Id" name="Id" type="hidden" value="">
<div class="form-group">
<label class="control-label col-md-4" for="CaseNumber">Case Number</label>
<div class="col-md-8">
<input class="form-control text-box single-line" data-val="true" data-val-required="The Case Number field is required." id="CaseNumber" name="CaseNumber" type="text" value="">
<span class="field-validation-valid" data-valmsg-for="CaseNumber" data-valmsg-replace="true"></span>
</div>
</div>
<div class="form-group">
<label class="control-label col-md-4" for="DateOfIncident">Date Of Incident</label>
<div class="col-md-8">
<input class="form-control text-box single-line valid" data-val="true" data-val-required="The Date of Incident field is required." id="DateOfIncident" name="DateOfIncident" type="date" value="">
<span class="field-validation-valid" data-valmsg-for="DateOfIncident" data-valmsg-replace="true"></span>
</div>
</div>
</div>
<div class="col-lg-6">
<div class="form-group">
<label class="control-label col-md-4" for="Description">Description</label>
<div class="col-md-8">
<textarea class="form-control text-box multi-line" data-val="true" data-val-required="The Description field is required." id="Description" name="Description"></textarea>
<span class="field-validation-valid" data-valmsg-for="Description" data-valmsg-replace="true"></span>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</form>
<table class="table table-striped table-hover " id="CrimeList">
<thead>
<tr>
<th>Case Number</th>
<th>Date of Incident</th>
<th>Description</th>
<th></th>
</tr>
</thead>
<tbody data-bind="foreach: items">
<tr>
<td data-bind="text: $data.CaseNumber">Column content</td>
<td data-bind="text: $data.DateOfIncident">Column content</td>
<td data-bind="text: $data.Description" style="text-wrap: normal">Column content</td>
@*<td></td>
<td></td>
<td></td>*@
<td>...</td>
</tr>
</tbody>
</table>
这是 client_crime_kjs.js 的代码，以及我所有的 KnouckoutJS 视图模型代码：
$(document).ready(
function ()
{
var Crime = function(CaseNumber, DateOfIncident, Description)
{
this.CaseNumber = CaseNumber;
this.DateOfIncident = DateOfIncident;
this.Description = Description;
}
var initialData = new Array();
var crimes = function (items)
{
var self = this;
//Data
self.items = ko.observableArray(items)
//operations
self.addCrime = function()
{
if ($("#AddCrimeForm").valid()) {
self.crime = new Crime($("#CaseNumber").val(), $("#DateOfIncident").val(), $("#Description").val());
//var JSONObj = { CaseNumber: $("#CaseNumber").val(), DateOfIncident: $("#DateOfIncident").val(), Description: $("#Description").val() };
self.items.push(this.crime);
}
//$("#CaseNumber").val() = "";
//$("#DateOfIncident").val() = "";
//$("#Description").val() = "";
}
}
ko.applyBindings(crimes(initialData), $("#CrimeList")[0])
}
);
基本上在这个阶段发生的情况是，当字段无效时，表单不会提交（正确如此），但是当它验证时它确实提交（与我的要求相反），并且我的 KO observablearray 随后重置。
