引入jquery插件问题 报错

html代码

 <!DOCTYPE html>
<html>
<head>
<script src="jquery.pagination.js"></script>
<script src="jquery-1.11.1.min.js"></script>
<script >
alert(1);
$('.M-box').pagination({

callback:function(index){
    $('.now').text(index);
}
},function(api){

$('.now').text(api.getCurrent());
});
</script>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<div class="M-box"></div>
</body>
</html>

jquery.pagination.js和jquery-1.11.1.min.js文件都放项目下了
报错Uncaught ReferenceError: jQuery is not defined
43.html:8
Uncaught TypeError: $(...).pagination is not a function word_search.js:155
Uncaught TypeError: Cannot read property 'id' of null

发现jquery,js应该在第一行。。改了之后

Uncaught TypeError: Cannot read property 'id' of null 这个错啥意思。。

放入dom ready中,要不找不到对象

     $(function () {
        $('.M-box').pagination({

            callback: function (index) {
                $('.now').text(index);
            }
        }, function (api) {

            $('.now').text(api.getCurrent());
        });
    })
