    </style>
    
    <script type="text/javascript">
       
            $("#more").click(function(){
                var text = $("#more").text();
                if(text == '更多'){
                    $(".hidden").show();
                    $("#more").text("简化");
                }
                else{
                    $(".hidden").hide();
                    $("#more").text("更多");
                }
            });
        
            
    </script>
    <body>
        <ul>
            <li>1</li>
            <li>1</li>
            <li class="hidden">1</li>
            <li class="hidden">1</li>

两个问题，使用jq的时候要先引用<script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>

a的点击事件的先去掉去跳转<a href="javascript:void(0);" id="more" onclick="js_method();return false;">更多</a>
