jQuery 回调函数 缺少”:” 错误

 

使用jQuery官方网站提供的例子无法运行，老是报缺少”:” 不知道是什么原因。

 

 

 

Load JSON data using an HTTP GET request.

As of jQuery 1.2, you can load JSON data located on another domain if you specify a  JSONPcallback, which can be done like so: "myurl?callback=?". (The other domain needs to support JSON-P output.) jQuery automatically replaces the ? with the correct method name to call, calling your specified callback. This callback parameter may vary depending on API, for instance Yahoo Pipes requires "_callback=?"

Note: Keep in mind, that lines after this function will be executed before callback.

$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?tags=cat&tagmode=any&format=json&jsoncallback=?",
        function(data){
          $.each(data.items, function(i,item){
            $("<img/>").attr("src", item.media.m).appendTo("#images");
            if ( i == 3 ) return false;
          });
        });

 

所以还是使用老版本的 $.getJSON函数：

 function getResult(){
	$.getJSON(path,null,function call(data){
	    flag_sync = data.result;
	    if(flag_sync == true) {
	     	$("#waitdiv").hide();
		$("#main").show('slow');
	    }else {
	    	setTimeout(function() { getResult() }, interval_getSyncflag);
	    }
   	});
 }
