I have a .jsp page in which I used on click JavaScript function for further validation and other processing stuff. Now I've created an array in jsp scriptlets and how do I pass into this JavaScript function that gets called when submit button is hit? I tried something like this:
var jsArray = <%=lineArray%>;
But that didn't work out.
In fact the function wasn't getting called after I the put above scriptlet. So how do I copy this java array into a JavaScript array?
Try something like this:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
var jsArray = [
<c:forEach var="item" items="${lineArray}">
<c:out value="${item}"/>,
</c:forEach>
];
This will generate javascript array variable jsArray and put the Java lineArray values into it. If that's what you need to do.
Actually You can't Access Java object(server) directly Into "JavaScript"(client). You have to Create a service(Ajax call) and get the response Object from the server........
But you can do something like this.....
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
var jsArray = {
<c:forEach items="${employees}" var="employee">
"${employee.id}": {
name:"${employee.employeeName}",
cv:"${employee.employeeCV}",
},
</c:forEach>
}
After Jsp parse....
var employees = {
"1": {
name:"foo",
cv:"cv1",
},
"2": {
name:"bar",
cv:"cv2",
},
}
Then you can modify js object as per your need...
