私のataから、最初の5つの値を取得するだけです。Jquery を使用してどのようにできるか。

スライスメソッドを使用できます

var first5 = server.slice(0,5)

array.slice(begin[, end])

詳細な構文はこちら

これを使用してみてください：

server.slice(0,5)

このコードを試してみてください。これが必要なものだと思います。

$(document).ready(function() {
    $.each(server, function(index, item) {
                if(index < 5) {
                    //DoSomeThings
                } else {
                    return;
                }
            });
       });

forループを使用します。

for (var i = 0; i < 5; i++) {
   var obj = server[i];

   // Do something...
   // obj.jobid, obj.browser, etc.
}

jQueryを使用している場合:

$.getJSON('/api/Controller/Action', {}, function (result) {
    $.each(result, function (i, v) {
        if (i > 4) return false; // Stop processing after 5 entries

        // 'v' now is your current object
        // v.jobid, v.browser, etc.
    });
});

.forEach()ではなく .each( )であるべきだと思います

server.each(function (index,result) {
  if(index<5){
   //do stuff;
  //array.push(item);
  }     
});
