html 5检查Mobile App是否在线

               

在PhoneGap应用,或者黑莓Java/HTML混搭应用中,如何使用JavaScript检查Mobile App网络连接状态呢?

<script type="text/javascript"if (navigator.onLine) {      alert("online");  } else {      alert("offline");  }</script>

jQuery Mobile中显示online/offline状态

<div data-role="content">    <button id="home_network_button" data-icon="check">Internet Access Enabled</button>  </div>
  <script type="text/javascript"if (navigator.onLine) {     } else {       $("#home_network_button").text('No Internet Access')      .attr("data-icon", "delete")      .button('refresh');   }    </script></div>
