没有验证属性的部分视图 (ASP.NET MVC 3)
我的一个 ASP.NET MVC 3 应用程序不断发生奇怪的事情。
我通过 jQuery Ajax api 获取插入行,这没有问题。但是,当我返回必要的部分视图时,它没有验证属性,并且我无法重新绑定这些行的验证。
这是我得到的 ajax 响应:
<input type="hidden" name="accommPropertyPeriods.index" autocomplete="off" value="ccaa15b3-76f1-4215-8bb5-a62d700bfc1e" />
<table style="width:100%;">
<tr>
<td>
<div class="editor-field">
<select class="chzn-select-deselect" data-placeholder="Choose an Alias..." id="accommPropertyPeriods_ccaa15b3-76f1-4215-8bb5-a62d700bfc1e__AccommPropertySeasonPeriodAliasID" name="accommPropertyPeriods[ccaa15b3-76f1-4215-8bb5-a62d700bfc1e].AccommPropertySeasonPeriodAliasID" style="min-width:100px;"><option value="302">A</option>
<option value="303">B</option>
<option value="304">C</option>
<option value="305">D</option>
</select>
</div>
</td>
<td>
<div class="editor-field">
<input class="datefield" id="accommPropertyPeriods_ccaa15b3-76f1-4215-8bb5-a62d700bfc1e__PeriodStartsAt" name="accommPropertyPeriods[ccaa15b3-76f1-4215-8bb5-a62d700bfc1e].PeriodStartsAt" type="text" value="" />
</div>
</td>
<td>
<div class="editor-field">
<input class="datefield" id="accommPropertyPeriods_ccaa15b3-76f1-4215-8bb5-a62d700bfc1e__PeriodEndsAt" name="accommPropertyPeriods[ccaa15b3-76f1-4215-8bb5-a62d700bfc1e].PeriodEndsAt" type="text" value="" />
</div>
</td>
</tr>
</table>
这是我应该得到的:
<input type="hidden" name="accommPropertyPeriods.index" autocomplete="off" value="84ddd0f5-a3e2-4f10-8e67-f32528c6393d" />
<table style="width:100%;">

GUID 不必相同。我正在进行所谓的非顺序绑定。
这是我通过 jquery ajax 调用以获得新插入行的操作:
[HttpPost]
public PartialViewResult accommPropertySeasonPeriodCreatePartialView(int id, int subid) {
//some other stuff going on here. non-related to partial view.
return PartialView("_AccommPropertySeasonPeriodCreatePartialView");
}
我几乎无法弄清楚为什么会发生这种情况。有什么想法吗?
A weird thing keeps happening on one of my ASP.NET MVC 3 apps.
I am fetching insert rows via jQuery Ajax api and there is no problem with that. But when I get the necessary partial view back, it is coming without validation attributes and I am unable to rebind the validation for those rows.
Here is what I get as ajax response:
<input type="hidden" name="accommPropertyPeriods.index" autocomplete="off" value="ccaa15b3-76f1-4215-8bb5-a62d700bfc1e" />
<table style="width:100%;">
<tr>
<td>
<div class="editor-field">
<select class="chzn-select-deselect" data-placeholder="Choose an Alias..." id="accommPropertyPeriods_ccaa15b3-76f1-4215-8bb5-a62d700bfc1e__AccommPropertySeasonPeriodAliasID" name="accommPropertyPeriods[ccaa15b3-76f1-4215-8bb5-a62d700bfc1e].AccommPropertySeasonPeriodAliasID" style="min-width:100px;"><option value="302">A</option>
<option value="303">B</option>
<option value="304">C</option>
<option value="305">D</option>
</select>
</div>
</td>
<td>
<div class="editor-field">
<input class="datefield" id="accommPropertyPeriods_ccaa15b3-76f1-4215-8bb5-a62d700bfc1e__PeriodStartsAt" name="accommPropertyPeriods[ccaa15b3-76f1-4215-8bb5-a62d700bfc1e].PeriodStartsAt" type="text" value="" />
</div>
</td>
<td>
<div class="editor-field">

</div>
</td>
</tr>
</table>
Here is what I should be getting :
<input type="hidden" name="accommPropertyPeriods.index" autocomplete="off" value="84ddd0f5-a3e2-4f10-8e67-f32528c6393d" />

GUIDs don't have to be the same. I am doing so-called non-sequential binding.
Here is the the action which I am invoking through jquery ajax to get a new insert row:
[HttpPost]
public PartialViewResult accommPropertySeasonPeriodCreatePartialView(int id, int subid) {
//some other stuff going on here. non-related to partial view.
return PartialView("_AccommPropertySeasonPeriodCreatePartialView");
}
I am nearly out of my mind to figure out why this is happening. Any idea?

Html.*
帮助器(例如Html.TextBoxFor
、Html.CheckBoxFor
...)仅在表单内使用时才会发出验证属性。因此,请确保将它们包装在Html.BeginForm
调用中。就客户端验证而言,您应该调用jQuery.validator.unobtrusive.parse
方法在更新 DOM 后重新应用客户端验证。还有另一篇文章。如果您没有表单,您可以作弊并将以下内容放入部分中:
现在帮助器将在输入字段上发出 data-* 验证属性。
The
Html.*
helpers such asHtml.TextBoxFor
,Html.CheckBoxFor
, ... emit validation attributes only if used inside a form. So make sure you wrap them in aHtml.BeginForm
call. As far as client side validation is concerned, you should call thejQuery.validator.unobtrusive.parse
method after you update your DOM in order to reapply client validation. And yet another article.If you don't have a form you can cheat and put the following in the partial:
Now the helper will emit data-* validation attributes on the input field.
