胸腺th:每个在元素之间添加昏迷 [英] Thymeleaf th:each adding coma between elements

问题描述

我有收藏集X

我遍历它并像这样写它:

I iterate through it and write it like that:

<span th:each="a, stat : ${X}"
      th:text="${X[__${stat.index}__].someProperty} + ','">
</span>

我其他的尝试是:

<span th:each="a, stat : ${X}" th:for="|a${stat.index}|"
      th:text="${X[__${stat.index}__].someProperty} + ','">
</span>

不幸的是，输出是相同的.

unfortunately the output is the same.

范围中的输出为:

test1, test2, test3,

我希望输出为:

test1, test2, test3

，末尾没有逗号.我该如何实现?

without the comma at the end. How can I achieve that?

解决方案:

1. 提防与元素类型span相关的属性th:text的值不得包含'<'字符.

1. Beware of The value of attribute th:text associated with an element type span must not contain the '<' character.

代码:

<span th:each="a, stat : ${X}"
      th:text=" ${X[__${stat.index}__].someProperty} +  (${stat.size-1 > stat.index}? ',':'') ">
</span>

推荐答案

Thymeleaf具有迭代属性last，请参见此处的文档:

Thymeleaf has an iteration property last see the documentation here: http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#keeping-iteration-status

使用

<span th:each="a, iterStat : ${X}" th:text="!${iterStat.last} ? ${a} + ',': ${a}"></span>
