    }
   });
   

2. $("#feeds").load("feeds.php", {limit: 25}, function(){
     alert("The last 25 entries in the feed have been loaded");
   });

3. $.get("test.cgi", { name: "John", time: "2pm" },
    function(data){
      alert("Data Loaded: " + data);
    });

success: function (data) {
var item = eval(data.d);
var StrHtml = "";
for (var i in item) {}
}, async: false
});

$("#b01").click(function(){
htmlobj=$.ajax({url:"/jquery/test1.txt",async:false});
