将值数组存储在 html（来自 php）属性中然后从 javascript/jQuery 访问它们的最佳实践是什么？

<div class="storage" someAttr=?? /></div>

它基本上是一个简单的数组，就像(code_1,code_2,code_3,...)
我想做一个简单的someAttr="code_1;code_2;code_3"然后爆炸它一样：

      var a = $(this).attr('someAttr');
      (a.split(";")).forEach(function (attr){
        console.log(attr);
      });

我试图实现一个相当简单的目标.有一个螺旋桨的imageView,旋转的无限LinearInterpolator动画直到按下按钮.用户按下按钮后,如何将动画减慢到停止状态？

这是一个非常简单的动画代码:

<?xml version="1.0" encoding="UTF-8"?>
<rotate
    android:interpolator="@anim/linear_interpolator"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:toDegrees="360"
    android:pivotX="50%"
    android:pivotY="50%"
    android:repeatCount="infinite"
    android:fillAfter="true"
    android:fillEnabled="true"
    android:duration="800" />

如何从课堂上取消注册接收器？到目前为止我得到了这个代码..当我第一次按下按钮时,一切正常,但当我再次按下它时,应用程序崩溃并出现错误:..Error接收广播意图...并且错误未得到处理.根据我的理解,我不能两次注册接收器,但如何克服这一点？

public class ApplianceButtonToggleOnClickListener implements OnCheckedChangeListener {
LinearLayoutWithImage mHardwareCell;
Activity mActivity;
    public ApplianceButtonToggleOnClickListener(
            LinearLayoutWithImage mHardwareCell, Activity mActivity) {
        this.mHardwareCell = mHardwareCell;
        this.mActivity = mActivity;
    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
     ...

          mActivity.startService(intentMyIntentService);
          ApplianceStateChangeSuccessReceiver successReceiver = new  ApplianceStateChangeSuccessReceiver(mActivity,mHardwareCell);
          IntentFilter intentHardwareSyncFilter = new IntentFilter(UpdateHardwareStateService.ACTION_UpdateHardwareStateService);
      intentHardwareSyncFilter.addCategory(Intent.CATEGORY_DEFAULT);    


      try {
          mActivity.registerReceiver(successReceiver, intentHardwareSyncFilter);} catch (IllegalArgumentException e) {
                Log.d ("APPLIANCE_BUTTON_TOGGLE_ON_CLICK", "ApplianceButtonToggleOnClick: error " +e);
          }



    }

}
