PHP ArrayHelper::removeKeys方法代码示例

 /**
  * Generates the JavaScript with the specified client changes.
  * @param string $event event name (without 'on')
  * @param array $htmlOptions HTML attributes which may contain the following special attributes
  * specifying the client change behaviors:
  * <ul>
  * <li>submit: string, specifies the URL to submit to. If the current element has a parent form, that form will be
  * submitted, and if 'submit' is non-empty its value will replace the form's URL. If there is no parent form the
  * data listed in 'params' will be submitted instead (via POST method), to the URL in 'submit' or the currently
  * requested URL if 'submit' is empty. Please note that if the 'csrf' setting is true, the CSRF token will be
  * included in the params too.</li>
  * <li>params: array, name-value pairs that should be submitted together with the form. This is only used when 'submit' option is specified.</li>
  * <li>csrf: boolean, whether a CSRF token should be automatically included in 'params' when {@link CHttpRequest::enableCsrfValidation} is true. Defaults to false.
  * You may want to set this to be true if there is no enclosing form around this element.
  * This option is meaningful only when 'submit' option is set.</li>
  * <li>return: boolean, the return value of the javascript. Defaults to false, meaning that the execution of
  * javascript would not cause the default behavior of the event.</li>
  * <li>confirm: string, specifies the message that should show in a pop-up confirmation dialog.</li>
  * <li>ajax: array, specifies the AJAX options (see {@link ajax}).</li>
  * <li>live: boolean, whether the event handler should be delegated or directly bound.
  * If not set, {@link liveEvents} will be used. This option has been available since version 1.1.11.</li>
  * </ul>
  * @see http://www.yiiframework.com/doc/api/1.1/CHtml/#clientChange-detail
