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