Jstl choose when boolean algebra

You can have a look at the EL (expression language) description here. Both your code are correct, but I prefer the second one, as comparing a. JSTL core tags: c:choose,c:when,c:otherwise - syntax, description and code boolean. The test expression which determines whether the body of the tag is The c:when>tag has an attribute 'test' to indicate test expression. The question-mark denotes the end of the boolean expression, and what follows is what will be used when the condition is true. The colon.

taglib prefix="c" uri="vozdejubilo.com" %> EL Expression Examples Boolean and Null Values c:set. Examine the JSTL expression language in detail, starting with expressions The logical operators prefer to work with Boolean operands. Subsequently, the c: out> action accesses the first item in the array with ${array[0]}. c:if> action. The most basic and simplest condition is c:if> action. The c:if> action is used to output its body content based on a Boolean expression.

The set of JSTL conditional tags are designed to support the two most c:if>. With mutually exclusive conditional execution, only one among a number of this is by simply having a custom logic tag export a boolean scripting variable. c:if> is a JSTL core tag which is used for testing conditions. For using this tag we generally use expression language to evaluate an relational expression. after evaluating the condition and we need the boolean value for test attribute. And you'll learn about JSTL's simplified expression language. The result of the comparison is returned as a boolean value. The logical operators The first JSTL custom tag we will consider is the c:set> action. As already. Earlier we have seen examples of JSTL foreach tag and JSTL core set tag boolean expression" var="variable" scope="scope">.
