我想在不使用JQuery的情况下从跨域获取JSON数组.来自跨域的数据如下:

{
      "transactionid": "LBS_48550801",
      "status": 0,
      "countrylist": 
    [
   { "id": 1, "name": "France", "latitude": 37.00039, "longitude": 35.31411, "extent": { "minlatitude": 36.53888499, "minlongitude": 34.76786904, "maxlatitude": 38.37851496, "maxlongitude": 36.40534884 }},
   { "id": 2, "name": "Germany", "latitude": 37.76454, "longitude": 38.27645, "extent": { "minlatitude": 37.40771898, "minlongitude": 37.43326512, "maxlatitude": 38.21203404, "maxlongitude": 39.24767592 } },
   //... .... .... 
   //... .... .... 
   //... .... .... 
   { "id": 98, "name": "Belgium", "latitude": 38.75754, "longitude": 30.5387, "extent": { "minlatitude": 37.78126803, "minlongitude": 29.68963308, "maxlatitude": 39.27915099, "maxlongitude": 31.71549708 } },
   { …

我想将一个Javascript值传递给JSP中的Java函数.我怎样才能做到这一点？id来自JSP中的组合框,通过Javascript.我将从ComboBox获取ID并将其作为参数发送到Java函数以获取Java结果.

function Display()
{
   var IdFromCB = (document.getElementById("MListSelect")).value;
   //CALL JAVA FUNCTION HERE BY USING IdFromCB as function parameter
   //'<% getSomething(-----IdFromCB-----);%>'

}

谢谢,马克
