This is probably an easy question but I can't seem to think of an answer to it.
I have this simple Thymeleaf code:
<ul data-th-switch="${someVar}">
<li data-th-case="${gt 6}">someVar is greater than 6.</li>
<li data-th-case="*">Default case.</li>
</ul>
I get an error on data-th-case="${gt 6}". Is there a way to do this in Thymeleaf?
Thanks in advance.
The syntax is wrong indeed. Details.
A correct syntax one be "${someVar} gt 6" but of course, it will not work correctly, although the template will render. That is because ${someVar} evaluates to 12 (for example) while ${someVar} gt 6 evaluates to true. These are not equal.
If you enable the ThyemeLeaf trace you will see how thymeleaf will interpret this:
o.t.s.expression.GreaterThanExpression : Evaluating GREATER THAN expression: "${someVar} > 6". Left is "12", right is "6". Result is "true"
o.t.s.expression.EqualsExpression : Evaluating EQUALS expression: "${someVar} == (${someVar} > 6)". Left is "12", right is "true". Result is "false"
Depending on the logic which you want to implement you may come to very different solutions - e.g. from putting a gadget in your model to implementing if-else logic. Check this question for some more ideas.
