I am building a JSP page that contains several IF statements when checking the data being loaded. I would like to call a jQuery function if one of those IF statements renders true. Is this possible?
example:
<c:if test="${!setvariable}">
$(function(){
//execute code here;
});
</c:if>
I can only find answers if a JSP is called within a Jquery function, and not this opposite way.
Why not? Of course, this works.
Your JavaScript code will only be sent to the client by <c:if> if the condition is true.
<script></script> tags around the JavaScript. Or rather it will be sent to the client but the client still needs to know that it should be evaluated as JavaScript and thus the need for the tags. <c:set var="myVar" value="${3000}"/>
<c:if test="${myVar < 1000}">
<script>
$(function () {
alert("Value less than 1000");
});
</script>
Variable <c:out value="${myVar}"/>
</c:if>
<c:if test="${myVar > 2000}">
<script>
$(function () {
alert("Greater than 2000");
});
</script>
Variable <c:out value="${myVar}"/>
</c:if>
Output :
Variable 3000
