如何在鼠标悬停时调用 c# 按钮单击

Question

我正在开发购物车应用程序，我在 ListView 中列出了所有产品。然后单击每个产品的按钮，图像滑块会发生变化。现在我想在鼠标悬停而不是单击时进行。下面是我试图实现的代码。

平均售价

 <div class="col-md-12 ">
                <div class="col-md-4 single_left pull-left">
                    <div class="flexslider">

Answer 1

我必须说，您触发点击的鼠标悬停方法似乎不是正确的解决方案。 （只是说）

无论如何 - 将您的代码更改为：

<asp:LinkButton ... CssClass="myButton"
  ...                   
</asp:LinkButton>

然后，通过 jQuery（您已经使用过）：

$(function (){
    $(".myButton").on('mouseover',function (){this.click()});
});
