控制台中出现javascript错误。尝试在jquery文档就绪而不是body onLoad上运行该函数。另外，没有定义likes，它应该是json.likes

您是否尝试过通过url的ID来调用它？同样的https/http协议也适用于这里。您可能需要使用document.location.protocol调用url，以匹配调用文档的当前协议

仍然不起作用-那个？回调=？这是因为我正在从另一个域FaceBook中提取JSON，我会这么做！还有，你能帮我做点别的吗？我将ul>li更改为带有id的div，这很好，但在这个文件的末尾我添加了这个，但它不起作用：-/var x=document.getElementsByClassNameconnect\u widget\u button\u count\u count[0]。innerHTML；如果x<153{document.writemarked}或者{document.writeddn不起作用}@Marco：你应该这样做，因为它似乎与这个没有关系。仍然不起作用-那个？回调=？这是因为我正在从另一个域FaceBook中提取JSON，我会这么做！还有，你能帮我做点别的吗？我将ul>li更改为带有id的div，这很好，但在这个文件的末尾我添加了这个，但它不起作用：-/var x=document.getElementsByClassNameconnect\u widget\u button\u count\u count[0]。innerHTML；如果x<153{document.writeworked}或者{document.writeddn不起作用}@Marco：你应该这样做，因为它似乎与这个没有关系。
