JSP和JavaScript衝突我認爲

-1

嗯，我有一個HTML格式的文件。當我將它作爲一個jsp文件進行更改並放入某些jsp代碼時，javascript停止響應並且沒有任何反應。這只是一個貨幣轉換器，交換按鈕通過JavaScript進行管理。JSP和JavaScript衝突我認爲

下面是代碼：

<html> 
<head> 
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.js"></script> 
    <script type="text/javascript"> 
     $(document).ready(function() { 
      $('#swap').click(function() { 
        s1=$('#to').val();   
        s0=$('#from').val();   
        $('#to').val(s0);   
        $('#from').val(s1); 
      }); 
     }); 
</script> 
</head> 
<body> 

    <%@ page import="java.util.*" %> 

    <div class="background"></div> 

    <div id="heading"> 
     <% 
     String currency = (String)request.getAttribute("currency"); 
     if(currency == null) 
     { 
      out.print("live currency converter"); 
     }else{ 
      out.println("Currency Converted: " +currency); 
     } 
     %> 
    </div> 

<div id="currencyBox"> 
<form method="POST" action="CurrencyConverter.do"> 

    <div class="data"> 
     <label for="from">Convert:</label> 
     <input type="text" name="amount" id="amount" value="1" /> 
    </div> 
    <div class="data"> 
     <label for="fromCurrency">From Currency:</label> 
     <select name="from" id="from"> 
      <option selected="" value="EUR">Euro - EUR</option> 
      <option value="USD">United States Dollars - USD</option> 
      <option value="GBP">United Kingdom Pounds - GBP</option> 
     </select> 
    </div> 

    <div class="data"> 
     <label for="to">To Currency:</label> 
     <select name="to" id="to"> 
      <option value="USD">United States Dollars - USD</option> 
      <option value="GBP">United Kingdom Pounds - GBP</option> 
      <option value="CAD">Canada Dollars - CAD</option> 
     </select> 
    </div> 
    <div class="data"> 
     <input type="submit" name="submit" id="submit" value="Convert the input"> 
     <input type="button" name="swap" id="swap" value="Swap values"> 
    </div> 
</form> 
<form method="GET" action="CodeGrabber.do"><input type="submit" value="Grab the code!"></form> 
<form method="GET" action="ListenTest.do"><input type="submit" value="On line report!"></form> 

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

當我刪除了<% %>部分的代碼在上面的作品就像一個魅力的JavaScript。我不熟悉jsp和servlets，我有一個php背景！

這裏是開發模式我的輸出

這就是即使Java看起來像一個普通的舊PHP腳本:)。 – FloydThreepwood

一眼就看不出是什麼原因造成的。發佈頁面的實際瀏覽器源輸出。正如Balus所說，JSP不是你的根本問題。 – Matthew

根據您對我已刪除答案的評論，您尚未發佈真實的SSCCE。你已經發布了一個半透明的，過度簡化和不完整的代碼片段，並不代表你真正的問題。作爲示例，請在演示之前自行運行代碼。 – BalusC

我不知道你所說的「開發商模式」的意思 - 就是你所看到的，當你在瀏覽器中加載頁面，然後單擊「查看源文件「？ - 但由於所有「Â」字符，以下JavaScript無效。他們來自哪裏？

$(document).ready(function() { 
     $('#swap').click(function() { 
    Â   s1=$('#to').val(); Â 
    Â   s0=$('#from').val(); Â 
    Â   $('#to').val(s0); Â 
    Â   $('#from').val(s1); 
      }); 
    });

我沒有看到任何方式，在<% %>標籤Java代碼可能會造成任何問題。

是的，這也很奇怪，但只有當我將代碼放入代碼<% %>剛剛消失，JavaScript再次順利運行......我無法在我的IDE（尾聲）中看到這些字符。他們不存在那裏。 –

解決它只是刪除新行 –
