Question

事情是我的2警报运作良好，但不是我的功能！它在Chrome和Firefox上完美运行，但在safari中我的ShowLoading（）没有显示

 <form onsubmit="alert('lol');ShowLoading(); alert('bla'); return true;" method="post" class="std" enctype="multipart/form-data">

我的功能：

function ShowLoading() {

var loading_screen = pleaseWait({
logo: "logoloader.png",
backgroundColor: 'rgba(23, 22, 22, 0.94)',
loadingHtml: ""
}); 
}

我使用please-wait.js：http://pathgather.github.io/please-wait/

让我们尝试新的东西：

  <script>
      function ShowLoading() {
         var loading_screen = pleaseWait({
             logo: "logoloader.png",
             backgroundColor: 'rgba(23, 22, 22, 0.94)',
             loadingHtml: ""
         }); 
       }
      $('#test').click(function() {
          alert('click!');
          ShowLoading();
          $('#target').submit();
      });
  </script>
 <form id="target" method="post" class="std" enctype="multipart/form-data">
<div id="test">test</div>
</form>

这在实际提交之前发生。它适用于所有浏览器。我没有测试我的代码，就像我说它只是另一种方法。
