Question

在实现jquery mobile之前，我有以下代码正常工作。现在，我没有得到任何测试警报，所以它让我觉得它没有执行onbodyload函数。我如何让它工作？

    function onBodyLoad()
    {       
        document.addEventListener("deviceready",onDeviceReady,false);
        alert('body');
    }

    /* When this function is called, PhoneGap has been initialized and is ready to roll */
    /* If you are supporting your own protocol, the var invokeString will contain any arguments to the app launch.

    function onDeviceReady()
    {
    alert('device');

        // do your thing!
        parms = getUrlVars();
        type = parms['type'];
        page = parms['page'];
        if(page=='') {
         page = 0;
        }
        filter_value = parms['filter_val'];


        vars = articles_get_info(type,page,filter_value);

        document.getElementById('pagetitle').innerHTML = vars['title'];
        document.getElementById('pagecontent').innerHTML = vars['page'];

    }

    </script>
  </head>
  <body onload="alert('hello');onBodyLoad()">
  <div data-role="page">
  <div data-role="header" id="header"><a href="index.html" style="float:right;" class="btn">Back</a>
      <h1 id="pagetitle"></h1>
      </div>
      <div data-role="content" id="pagecontent">

      </div>
      </div>
  </body>
</html>

我已经尝试用以下内容替换onbodyload（）并删除onload =“”，但它仍然无效：

window.addEventListener('load', function () {
    document.addEventListener('deviceready', onDeviceReady, false);
}, false);

Answer 1

在加载文档时使用jQuery简写表示法：

$(function(){
    //The document is loaded. Put your code here
});

Answer 2

根据PhoneGap documentatio n，你可以这样做：

$( function() {
     document.addEventListener("deviceready", onDeviceReady, false);
});

function onDeviceReady（）{...}
