使用jquery查找具有特定属性的锚点(finding an anchor with a certain attribute using jquery)

我正在尝试在具有特定属性的div中找到一个锚点,但jquery代码用于查看锚点的hreef值,而不是锚点本身。 这是我正在使用的代码:

<script type="text/javascript">
            $(document).ready(function() {
            $("#ax_campaign_nav a").each(function (i) {
                if (this.attr('data-ident') == "ax_models") {
                        this.hide();
                    }
            });
        });
    </script>

我的链接看起来像这样:

<a href="javascript:void(0);" data-ident="ax_models" onclick="scrollToAnchor('#a_ax_models')">+ Model Bios</a>

我究竟做错了什么? 谢谢您的帮助。


I'm trying to find an anchor inside a div that posses a specific attribute, but the jquery code is for some looking at the hreef value of the anchor, not the anchor itself. This is the code I'm using:

<script type="text/javascript">
            $(document).ready(function() {
            $("#ax_campaign_nav a").each(function (i) {
                if (this.attr('data-ident') == "ax_models") {
                        this.hide();
                    }
            });
        });
    </script>

And my link looks like this:

<a href="javascript:void(0);" data-ident="ax_models" onclick="scrollToAnchor('#a_ax_models')">+ Model Bios</a>

What am I doing wrong? Thanks for the help.

最满意答案

如错误消息所示,您可以添加

android:exported="true"

对你的活动。

虽然如果我正确阅读android文档,这应该是默认值:

机器人:出口

活动是否可以由其他应用程序的组件启动 - 如果可以,则为“true”,否则为“false”。 如果为“false”,则活动只能由相同应用程序的组件或具有相同用户ID的应用程序启动。 默认值取决于活动是否包含意图过滤器。 缺少任何过滤器意味着只能通过指定其确切的类名来调用活动。 这意味着该活动仅供应用程序内部使用(因为其他人不知道类名)。 所以在这种情况下,默认值为“false”。 另一方面, 至少存在一个过滤器意味着该活动旨在供外部使用,因此默认值为“true”

也许其他人可以澄清这一点。


As the error message suggests, you could add

android:exported="true"

to your activity.

Although this should be the default value if I read the android documentation right:

android:exported

Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID. The default value depends on whether the activity contains intent filters. The absence of any filters means that the activity can be invoked only by specifying its exact class name. This implies that the activity is intended only for application-internal use (since others would not know the class name). So in this case, the default value is "false". On the other hand, the presence of at least one filter implies that the activity is intended for external use, so the default value is "true".

Maybe someone else can clarify this.
