I am using Ajax in my JavaScript and that sets an array of objects of following class in a response:
public class RetrieveTempSecVersions {
private String templateName;
private int[] versionNumber;
public String getTemplateName() {
return templateName;
}
public void setTemplateName(String templateName) {
this.templateName = templateName;
}
public int[] getVersionNumber() {
return versionNumber;
}
public void setVersionNumber(int[] i) {
this.versionNumber = i;
}
}
using:
aoRes.setContentType("text/xml");
aoRes.setHeader("Cache-Control", "no-cache");
aoRes.getWriter().write(template[]);
Now I want to read all the elements from template array and its details into my JavaScript.
Can anyone help me in how to do that?
JavaScript is designed on a simple object-based paradigm. An object is a collection of properties, and a property is an association between a name (or key) and a value. A property's value can be a function, in which case the property is known as a method.
Other Similar Java JVMDoppio – is a Java JVM that can run Java in a JavaScript engine. It is written in CoffeeScript. This is the one that claims to have the most support for features.
The call() method is a predefined JavaScript method. It can be used to invoke (call) a method with an owner object as an argument (parameter). With call() , an object can use a method belonging to another object.
A nested data structure is an array or object which refers to other arrays or objects, i.e. its values are arrays or objects. Such structures can be accessed by consecutively applying dot or bracket notation. Here is an example: const data = { code: 42, items: [{ id: 1, name: 'foo' }, { id: 2, name: 'bar' }] };
Have you considered using Google Web Toolkit? With GWT you have a number of choices for sending objects between client and server, including GWT RPC, RequestFactory, and JSON.
You need to transform your array of Java objects into something JavaScript understands. There are two obvious choices : XML (AJAX means Asynchronous Javascript And XML), or JSON. JSON is probably easier and more lightweight.
All the AJAX JavaScript libraries (JQuery, etc.) have good support for JSON. See http://api.jquery.com/jQuery.getJSON/ for example.
There are also several Java APIs to transform Java objects into JSON (look at GSON for example).
You'll have to modify the content type of the response : it's not text/html, but application/json if you use JSON.
