如何将变量作为字符串进行比较? [英] How to compare variables as String?

问题描述

如果 myData.value 是 blablabla 那么变量 tmp 应该等于 ABC:

 
<br><span th:utext="*{myData.value}">___</span><br><span th:utext="${tmp}">___</span>

输出:

<块引用>

blablabla
XYZ

解决方案

您可以以这种方式利用 thymeleaf 实用程序，例如 strings

<p th:text="${#strings.equals(first, second)}"></p><p th:text="${#strings.equalsIgnoreCase(first, second)}"></p>

在你的情况下是:

${#strings.equals(myData.value, blablabla)}

If the myData.value is blablabla then variable tmp should be equal ABC:

 <div th:with="tmp=*{myData.value} eq 'blablabla' ? 'ABC' : 'XYZ'">
      <br>
      <span th:utext="*{myData.value}">___</span>
      <br>
      <span th:utext="${tmp}">___</span>
</div>

Output:

blablabla
XYZ

解决方案

You can take advantage of thymeleaf utilities such as strings with that fashion

<p th:text="${#strings.equals(first, second)}"></p>
<p th:text="${#strings.equalsIgnoreCase(first, second)}"></p>

in your case it would be :

${#strings.equals(myData.value, blablabla)}
