GWT: creating associated jsarray

Question

I want to create a js array of type

Name(
{title : "Mr.",firstname : "Bill",lastname : "Gates"},
{title : "Mr.",firstname : "Bill",lastname : "Gates"},
{title : "Mr.",firstname : "Bill",lastname : "Gates"}
)

So basically i want to create associated array. All the examples are like converting javascript array to java but in my case i want the other way round. I will be filling this array from java.

JSArray and JsMixedArray seems to be doing this but i could figure out how to add to them.

Answer 1

One approach could be to use a JSNI method to create the items/entries of your Array/Map as follows:

 JsArray arr = JavaScriptObject.createArray().cast();
 arr.push(newEntry("Mr.", "Bill", "Gates"));      

 ....

 private final native JavaScriptObject newEntry(String title, 
                               String firstname, String lastname)/*-{
     return {title: title, firstname: firstname, lastname: lastname};
 }-*/; 

You could also try to create the data structure you have in mind using the JSON utility methods: Put JSONObjects inside a JSONArray.
