之前已经问过类似的问题(Custom ValidationSummary template Asp.net MVC 3)但是这两个答案都没有满足我的额外要求,即解决方案不会破坏客户端验证。
那么,有没有人知道如何获得这样的功能:
@if (!ViewData.ModelState.IsValid)
{
<div class="form-errors">
<p>Please have another look at the fields highlighted below</p>
@Html.ValidationSummary()
</div>
}
是否适用于客户端验证?
当客户端验证关闭时,这正是我想要的,即如果模型有效则排除整个div,如果有任何错误则显示它。但是,条件意味着当评估为false时首次呈现表单时,不会呈现整个部分,因此jquery.validate找不到任何插入验证摘要的位置。
有什么想法吗?

助手:
public static MvcHtmlString MyValidationSummary(this HtmlHelper helper, bool excludePropertyErrors = false)
{
string html = "";
html += helper.ViewData.ModelState.IsValid ? "<div class='form-errors' style='display:none;'>" : "<div class='form-errors'>";
html += "<p>Please have another look at the fields highlighted below</p>";
html += helper.ValidationSummary(excludePropertyErrors);
html += "</div>";
return new MvcHtmlString(html);
}
查看:
@using (Html.BeginForm("Index", "Home",FormMethod.Post, new {id="myform"}))
{
@Html.MyValidationSummary()
...
<input type="button" id="submitbutton" value="Submit" />
}
JS:
$("#submitbutton").click(function () {
$("#myform").validate();
if (!$("#myform").valid()) {
$("#myform .form-errors").show();
}
else {
$("#myform").submit();
}
});

如果你想使用局部视图
共享/ _MyValidationSummary.cshtml
@if (!ViewData.ModelState.IsValid)
{
<div class="form-errors">
<p>Please have another look at the fields highlighted below</p>
@Html.ValidationSummary()
</div>
}
else
{
<div class="form-errors" style="display:none;">
<p>Please have another look at the fields highlighted below</p>
@Html.ValidationSummary()
</div>
}
查看:
@using (Html.BeginForm("Index", "Home",FormMethod.Post, new {id="myform"}))
{
@Html.Partial("_MyValidationSummary")
...
<input type="button" id="submitbutton" value="Submit" />
}
