速度模板和javascript

java spring-mvc velocity

我尝试将javascript添加到我的速度模板中。

<html>

<head>
<title>:: $currency.CurrencyName Detail Info ::</title>
</head>

<body>
<table>
 <tr>
  <td>Name</td>
  <td>$currency.CurrencyName</td>
 </tr>
 <tr>
  <td>Jual</td>
  <td><div id="$currency.CurrencyName_buy">$currency.Buy</div></td>
 </tr>
 <tr>
  <td>Beli</td>
  <td><div id="$currency.CurrencyName_sell">$currency.Sell</div></td>
 </tr>
</table>


<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script>
    $(document).ready(function() {
        setInterval(function() {
            $.get('updateCurrency.htm', function(data) {
                $('#time').text(data);         
            });
        }, 5 * 60 * 1000); // 1000 milliseconds = 1 second.
    });
</script>

<p>Current date/time is: <span id="time"></span>
</body>

</html>

但我得到以下错误：

org.apache.velocity.exception.ParseErrorException: Encountered "," at line 28, column 29 of currencyDetail.html
Was expecting one of:

如果我删除javascript脚本，网页就会成功加载。任何人都可以解释为什么？我认为如果使用速度模板，javascript就不起作用了。

答案 1

在 Velocity 1.7b1 中引入了新的语法：#[[this is included in output but not parsed]]#

#[[
    $(document).ready(function() {
        ...
    });
]]#

答案 2

当我混合jquery和Velocity时，我发现最简单的方法是使用“jQuery”而不是$，例如

jQuery("#divid")

这避免了任何困难 - 在速度上逃避是棘手且不直观的。
