最近浏览过的商品

    public function actionView($id) {
        $model = $this->loadModel($id);

        /* 记录浏览历史 */

        if (isset(Yii::app()->request->cookies['history'])) {

            $history = explode(',', Yii::app()->request->cookies['history']->value);
            array_unshift($history, $id);
            $history = array_unique($history);

            while (count($history) > 5) {
                array_pop($history);
            }

            $cookie = new CHttpCookie('history', implode(',', $history));
            $cookie->expire = F::gmtime() + 3600 * 24 * 30;
            Yii::app()->request->cookies['history'] = $cookie;
        } else {
            $cookie = new CHttpCookie('history', $id);                     //value = $id;
            $cookie->expire = F::gmtime() + 3600 * 24 * 30;
            Yii::app()->request->cookies['history'] = $cookie;
        }

        /* 更新点击次数 */
        $model->click_count = $model->click_count + 1;
        $model->save();
        $this->render('view', array(
            'model' => $model,
        ));
    }

public function actionClearHistory() {
        unset(Yii::app()->request->cookies['history']);
    }

	/*
	 * 暴力清除商品浏览历史记录！
	 */
	$("#clearRec").click(function(event) {
            alert(1);
	    $.ajax({
		url: "<?php echo Yii::app()->createUrl('/item/clearHistory') ?>",
		async: false
	    }),
	    $(".recent").html("").append("<div style='padding:20px'>没有商品浏览记录!</div>");
