javascript 获取来源 document.referrer

这里要使用js location.href；$this->redirect()获取不到

// EntfavpersonController.class.php
class EntfavpersonController extends BaseController{

	function __construct(){
		parent::__construct();
		if(!session('ent_id')){
			die('<script>location.href="/zp/login/quick";</script>');
		}
	}

	function add($person_id=0,$job_id=0,$pk=0){

	}

}

// quick.html
<layout name="base2" />
<script>
	layui.use(['form', 'jquery', 'layer'], function () {
		var form = layui.form
			, $ = layui.jquery
			, layer = layui.layer
			, from = document.referrer

		console.log('from：', from)

	})
</script>
