當鼠標指針位於行上時,我想將行突出顯示到JSF表中。我發現這個tutorial突出顯示JSF數據表的行

我試圖執行這裏的例子:

<?xml version='1.0' encoding='UTF-8' ?>

    <h:head> 
     <ui:insert name="header">

     </ui:insert> 
     <script type="text/javascript" src="resources/js/jquery-1.7.2.min.js"></script> 
    </h:head> 
    <h:body> 

     <script type="text/javascript"> 

      $("tr").not(':first').hover(
       function() { 
       $(this).css("background","yellow"); 
       }, 
       function() { 
       $(this).css("background",""); 
       } 
      ); 

     </script> 

     <h1><img src="resources/css/images/icon.png" alt="NVIDIA.com" /> History Center</h1> 
     <!-- layer for black background of the buttons -->

        </h:form> 

       </div> 

       <div id="settingsdiva" style="width:350px; height:400px; position:absolute; background-color:transparent; top:20px; left:400px">

       <div id="settingsdivb" style="width:350px; height:400px; position:absolute; background-color:transparent; top:20px; left:800px"> 

       </div> 
      </div> 
     </div> 

    </h:body> 
</html> 

什麼也沒有發生。我想JavaScript必須能夠工作。在突出顯示JSF表格和普通HTML表格中的行時是否存在疑惑?也許問題是JQuery的版本?

最良好的祝願

的問題是,你的腳本被執行前的DOM完全加載。

您可以把您的腳本,因爲它是在頁面的底部,或者把它當文檔準備好把它裏面$(function() {})

<script type="text/javascript"> 
    $(function() { 
    $("tr").not(':first').hover(
     function() { 
     $(this).css("background","yellow"); 
     }, 
     function() { 
     $(this).css("background",""); 
     } 
    ); 
    }) 
</script>

如何在tr的click事件中添加相同的事物? – 2012-08-31 11:47:54

它甚至有可能嗎? – 2012-08-31 11:49:02

可以DataTable中使用這些JS行動呼籲:

onrowmouseover="this.style.cursor='default';this.style.backgroundColor='#F1F1F1';" 
onrowmouseout="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'"

什麼是添加此js操作的正確方法?我必須放置這些代碼的位置? – 2012-04-13 17:46:51

你可以像這樣在數據表中使用它: ....... 2012-04-13 19:57:27

是的,我嘗試,但Netbeans的返回我錯誤:屬性onrowmouseover是未在組件的界面 – 2012-04-13 20:28:16
