javascript – Jquery getJSON跨域问题

当使用 JQuerys getJSON从另一个域中拉出时,我似乎无法让我的JSON文件工作.我把回调部分放在了URL的末端,但仍然没有喜悦. Firebug告诉我一个跨域问题,这似乎是有道理的,好像我将本地的json文件放在下面的代码(不包括？jsoncallback =？工作正常)

属于Jquery部分

$.getJSON("http://anotherdomain/js/morearticles.js?jsoncallback=?",function(json){
        if (show5More.nextSetCount < json.items.length) { // Check not on last group of data
            $('#lineupswitch li').hide();  // Hide the existing items    
            $.each(json.items,function(key,value){ // Loop over the returned data from the json file
                if (key === show5More.nextSetCount) {  // If the itteration is equal to the datablock continure
                     show5More.nextSetCount = show5More.nextSetCount + 1; // 
                     $(value).each( function(index) {
                         if( (index % 2) == 0) {
                             $('<li class="even ' + this.cname +'"><a href="' + this.href + '" class="lineup-thumb"><img src="' + this.thumbimg + '" /></a><h3><a href="' + this.href + '">' + this.titletext + '</a></h3><p>' + this.paratext + '</p></li>').appendTo("#lineupswitch");
                          } else {
                              $('<li class="odd ' + this.cname +'"><a href="' + this.href + '" class="lineup-thumb"><img src="' + this.thumbimg + '" /></a><h3><a href="' + this.href + '">' + this.titletext + '</a></h3><p>' + this.paratext + '</p></li>').appendTo("#lineupswitch");                              
                          } 
                     });
                     return false;
                }
            });
        }
    });         
}

和我已经验证的JSON.

        ]
}

解决方法

altCognito是正确的.这是一个工作示例：

把它放在你打电话的页面的顶部

$.getJSON("http://www.yourotherdomain.com/testcross.PHP?jsoncallback=?",function(data){
      $('body').html(data.name).css("color","green");  
    });

和PHP将返回的东西：

$data = '{"name" : "hello world"}';
  echo $_GET['jsoncallback'] . '(' . $data . ');';
