Question

我正在开发一个c＃项目。

我有一个锚标记，我想基于某些条件添加/删除onlick和onserverclick属性。

设计： -

<a class="btnSelected" href="#" name="Platinum" onclick="if (!confirm('Are you sure you want to change the plan?')) return false;" onserverclick="UpdatePackage_Click" runat="server">upgrade</a>

jQuery的： -

 if ($("#" + '<%= hdnPackType.ClientID %>').val() != $("#" + '<%= hdnOrigionalPackType.ClientID %>').val()) {         
        $('a.btnSelected').html('select').attr("onclick", "if (!confirm('Are you sure you want to change the plan?')) return false;");
        }
        else {
            $('a.btnSelected').html('<i class="fa fa-check mr-10"></i>selected').removeAttr('onclick').removeAttr('href');
        }

您需要使用数据属性。我为你做了一个例子。

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools" tools:context="net.ossrs.yasea.demo.MainActivity">
    <item android:id="@+id/action_settings" android:title="action_settings"
        android:orderInCategory="200" app:showAsAction="never" />
  <item
        android:id="@+id/menu_search"
        android:menuCategory="system"
      android:title="action_settings"
        android:icon="@drawable/logo"
        app:showAsAction="always"

        />

    <item android:id="@+id/original_filter" android:title="Original"  app:showAsAction="never"/>
    <item android:id="@+id/beauty_filter" android:title="Beauty" app:showAsAction="never"/>
    <item android:id="@+id/cool_filter" android:title="Cool" app:showAsAction="never"/>
    <item android:id="@+id/early_bird_filter" android:title="Early Bird" app:showAsAction="never"/>
    <item android:id="@+id/evergreen_filter" android:title="Evergreen" app:showAsAction="never"/>
    <item android:id="@+id/n1977_filter" android:title="N1977" app:showAsAction="never"/>
    <item android:id="@+id/nostalgia_filter" android:title="Nostalgia" app:showAsAction="never"/>
    <item android:id="@+id/romance_filter" android:title="Romance" app:showAsAction="never"/>
    <item android:id="@+id/sunrise_filter" android:title="Sunrise" app:showAsAction="never"/>
    <item android:id="@+id/sunset_filter" android:title="Sunset" app:showAsAction="never"/>
    <item android:id="@+id/warm_filter" android:title="Warm" app:showAsAction="never"/>
    <item android:id="@+id/tender_filter" android:title="Tender" app:showAsAction="never"/>
    <item android:id="@+id/toast_filter" android:title="Toast" app:showAsAction="never"/>
    <item android:id="@+id/valencia_filter" android:title="Valencia" app:showAsAction="never"/>
    <item android:id="@+id/walden_filter" android:title="Walden" app:showAsAction="never"/>

</menu>

<div class="row text-center">
<div class="col-md-4">
    plan 1 
    <button class="btn btn-info btnSelect" data-plan="1">select</button>
</div>
<div class="col-md-4">
    plan 2
    <button class="btn btn-info btnSelect" data-plan="2">select</button>
</div>
<div class="col-md-4">
    plan 3
    <button class="btn btn-info btnSelect" data-plan="3">select</button>
</div>
