如何让 Velocity 输出大于/小于而不转义？

我试图让 Velocity 输出以下 Javascript 代码：

if ((whichOne+1) <= numCallouts ) {
whichOne = whichOne + 1; } else {
whichOne = 1;
     }

每当我尝试让 Velocity 打印 > 时或a <，表示为& > >或& lt;，这对我没有帮助，因为我试图让它生成 Javascript。我已经尝试过：

#set ( $gt = ">" )

但即使这样最终也会成为 & > >

提前致谢。

I'm trying to get Velocity to output the following Javascript code:

if ((whichOne+1) <= numCallouts ) {
whichOne = whichOne + 1; } else {
whichOne = 1;
     }

Whenever I try to get Velocity to print a > or a <, it represents it as a & gt; or & lt;, which doesn't help me since I'm trying to get it to produce Javascript. I've tried:

#set ( $gt = ">" )

But even that ends up as a & gt;

Thanks in advance.

这不是默认行为，我能想到发生这种情况的唯一原因是，如果您在 velocity.config 中配置了 EscapeHtmlReference 事件 ReferenceInsertionEventHandler 或在 Velocity 初始化代码中。

这是有关事件的更多信息

我对 Velocity 也有同样的问题 - 但是，问题是我使用 Velocity 作为第三方嵌入式语言，并且无权更改 Velocity 设置。

不幸的是，我能找到的唯一解决方案是重写代码而不显式使用大于/小于，这无疑是可怕的，但这都是为了让它工作......

这是您正在尝试的条件的示例解决方法查看一个数字是否大于另一个数字：

if (n1 > n2) //Doesn't work because velocity turns this into if (n1 > n2)

if (n1 != n2)
{
    diff = n1 - n2;
    abs = abs(n1 - n2);
    if (diff / abs == 1) //Greater than
    else //if == -1 then less than
}
else //Equal

I've had the same issue with Velocity - however, the problem is that I was using Velocity as an third party embedded language, and didn't have access to change the Velocity settings.

Unfortunately the only solution I was able to find was to rewrite the code without using greater than/less than explicitly, which admittedly is awful, but it's all about getting it to work...

Here is an example workaround for conditionals where you are trying to see if one number is larger than another:

if (n1 > n2) //Doesn't work because velocity turns this into if (n1 > n2)

if (n1 != n2)
{
    diff = n1 - n2;
    abs = abs(n1 - n2);
    if (diff / abs == 1) //Greater than
    else //if == -1 then less than
}
else //Equal
