这是我的html：

                join prodName in db.Products on req.ProductId equals prodName.Id
                join partRequestStatus in db.PartRequestStatus on req.PartRequestStatusId equals partRequestStatus.Id           
                select new ShowRequestsModel
                {                                                                                                                
                    WarantyExpirationDate = req.PurchasedDate.AddYears(2),
                    IsWarantyExpired = false

        <a href="http://HappyHelps.com/conseils-bac-de-francais/" class="responsive-menu-item-link">Commence ici !</a>
    </li>
    <li id="responsive-menu-item-6434" class="responsive-menu-item-current-ancestor">
        <a class="responsive-menu-item-link">Méthode
        <div class="responsive-menu-subarrow">▼</div>
        </a>
    </li>
    <ul class="responsive-menu-submenu responsive-menu-submenu-depth-1">
        <li id="responsive-menu-item-19480" class=" responsive-menu-item-current-ancestor">

            </a>
        </li>
        </ul>
</ul>

这就是我得到的错误：

未捕获的错误：语法错误，无法识别的表达式：[objectObject] .response-menu-subarrow

Answer 1

我想您应该使用如下的jQuery代码：

jQuery('.responsive-menu-item-link').click(function(){
    var clicked = jQuery(this);
    jQuery( clicked ).find(".responsive-menu-subarrow").trigger( "click" );
});

Answer 2

在您的代码中，clicked不是对象，因此.trigger()函数会出错。

尝试一下：

jQuery('.responsive-menu-item-link').click(function(){
     var clicked = jQuery(this);
    jQuery(clicked).find(".responsive-menu-subarrow").trigger( "click" );
 });

Answer 3

var clicked = jQuery(this);将返回.responsive-menu-item-link的DOM元素对象

尝试jQuery(".responsive-menu-item-link .responsive-menu-subarrow").trigger( "click" );

无法识别的表达式：[object Object] .class：jquery
