jquery 同步和异步请求

1. $.ajax 同步和异步请求

 1 $.ajax({
 2    type: "POST",
 3    url: "some.php",
 4    async : true,   // true 异步,false 同步 
 5    // or  data:{name:"John",locationi:"Boston"}
 6    data: "name=John&location=Boston",
 7    success: function(msg){
 8      alert( "Data Saved: " + msg );
 9    }
10 });

2. $.get 请求
jQuery.get(url, [data], [callback], [type]) String,Map,Function,String，请求成功时可调用回调函数。如果需要在出错时执行函数，请使用 $.ajax

1 $.get("test.cgi", { name: "John", time: "2pm" },function(data){
2     alert("Data Loaded: " + data);
3 });

jQuery.getJSON(url, [data], [callback])

3.$.post 请求

　　jQuery.post(url, [data], [callback], [type]) String,Map,Function,String

1 $.post("test.php", { name: "John", time: "2pm" }, function(data){
2      process(data);
3   });
