【问题描述】：
我在尝试调用时收到错误消息“Uncaught TypeError: $(...).valid is not a function”...
javascript
$('input[data-val=true]').on('blur', function() {
$(this).valid();
});
HTML
<div class="col-xs-12 col-sm-5" style="margin-left:4px">
<input required="True" class="form-control" data-bind="value: battleModel.ReserveTroopCount" data-val="true" data-val-number="The field Troop reserve must be a number." data-val-range="Troop reserve must be between 0 and 1000." data-val-range-max="1000" data-val-range-min="0" data-val-required="Troop reserve is required." id="ReserveTroopCount" name="ReserveTroopCount" placeholder="Troop reserve..." tabindex="1" title="Enter the minimum troops you want to reserve after the battle" type="text" value="5">
<span class="field-validation-valid" data-valmsg-for="ReserveTroopCount" data-valmsg-replace="true"></span>
</div>

我的 jquery 文件是本地的，但它们是有效的。今天刚刚将它们从 NuGet 中删除。我看到浏览器中加载了我的所有脚本...

我错过了什么？我在网上看到的所有内容都表明脚本参考丢失或顺序错误。不知道还能做什么。该错误表明引用的 jquery 文件没有被加载。我还尝试了对 jquery 文件的在线 cdn 引用，但得到了同样的错误。

当我将 jquery 版本从 1.11.1 更新到 3.x.x 时遇到了同样的问题。
