Internet Explorer中是否存在输入类型为“ image”的错误
|
我目前正在使用IE9（rtm），我想知道这是我自己做的问题还是Internet Explorer 9中的错误。
我正在使用ASP.NET MVC，将表单控制器定义为：
[HttpPost()]
[UrlRoute(Path = \"Checkout/Cart\")]
public ActionResult Cart(ShoppingCartModel cart, string submitButton)
<input type=\"image\" src=\"/resources/images/removeselected.png\" class=\"rightButton removeSelected\" alt=\"Remove Selected\" name=\"submitButton\" value=\"<%= Html.Encode(Model.REMOVE_SELECTED) %>\" />
submitButton=removeSelected
没有找到相关结果

，是的，但是根据规范，没有义务这样做。因此，您不应依赖此参数。其他浏览器正在发送它的事实可能只是实现细节（您当然不应该依赖它）。 解决方法是使用普通的提交按钮，然后尝试使用CSS设置样式。死狸蔽垂藐
