  • 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?

    1. <script type="text/javascript"> 
    2.   if (navigator.onLine) { 
    3.       alert("online"); 
    4.   } else { 
    5.       alert("offline"); 
    6.   } 
    7. </script> 
    <script type="text/javascript">
      if (navigator.onLine) {
          alert("online");
      } else {
          alert("offline");
      }
    </script>

    jQuery Mobile中显示online/offline状态

    1. <div data-role="content"> 
    2.     <button id="home_network_button" data-icon="check">Internet Access Enabled</button> 
    3.   </div> 
    <div data-role="content">
        <button id="home_network_button" data-icon="check">Internet Access Enabled</button>
      </div>
    
    
    1.   <script type="text/javascript"> 
    2.      if (navigator.onLine) {   
    3.       } else {   
    4.         $("#home_network_button").text('No Internet Access') 
    5.          .attr("data-icon", "delete") 
    6.          .button('refresh'); 
    7.       }   
    8.   </script> 
    9. </div> 
      <script type="text/javascript">
    	 if (navigator.onLine) {  
    	  } else {  
    	    $("#home_network_button").text('No Internet Access')
    	     .attr("data-icon", "delete")
    	     .button('refresh');
    	  }  
      </script>
    </div>
