我想检测JavaScript上的强制刷新事件。当用户单击浏览器重新加载按钮或按 Ctrl + f5 (在Windows上)/ Cmd + r (在Mac)和刷新在移动设备上。
我尝试了 // Code inside method evaluateJSONObject() that evaluate JSON received
//from http request to server that return the values for ListPreference
String currentEntry = (String) listPreferenceEntrances.getEntry();
listPreferenceEntrances.setEntries(entries);
listPreferenceEntrances.setEntryValues(entryValues);
listPreferenceEntrances.setSummary(currentEntry);
//Write the currentEntry into SharedPreferences
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString(getString(R.string.current_listpreference_entry_key), currentEntry);
editor.commit();
事件,但是此事件在每次加载页面时触发并导航到其他页面。
//SharedPreference instance
sharedPref = PreferenceManager.getDefaultSharedPreferences(this);
setBaseUrl();
// This show the string entry VALUE of selected ListPreference
String entry_settings_id = sharedPref
.getString("entry_preference", "-1");
// This show the string entry of selected ListPreference
String entry_settings_name = sharedPref
.getString(
getString(R.string.current_listpreference_entry_key),
getString(R.string.current_listpreference_entry_default_value));

我能想到的最佳解决方案是Navigation Timing
window.performance
属性提供了与性能相关的属性的托管区域。
if (window.performance) {
if (performance.navigation.type === performance.navigation.TYPE_RELOAD) {
console.info( "Reload detected" );
} else {
console.info( "Reload not detected");
}
} else {
console.info("window.performance is not supported");
}
