Question

我正在使用OMDb API来获取电影的标题，年份和运行时间。这些应该在加载后立即显示在页面上。我使用了j查询ajax。但它不起作用。

一旦页面加载，它就会显示未定义的内容。我在哪里弄错了？

我是j新查询ajax和API的，所以任何帮助都会受到赞赏。谢谢提前:)

为了从对象获取所有返回的值，您需要按键和值获取每个属性，返回的json如下所示：

{"Title":"Spiderman","Year":"1990","Rated":"N/A","Released":"N/A","Runtime":"5 min","Genre":"Short","Director":"Christian Davi","Writer":"N/A","Actors":"N/A","Plot":"N/A","Language":"German","Country":"Switzerland","Awards":"N/A","Poster":"N/A","Metascore":"N/A","imdbRating":"5.7","imdbVotes":"90","imdbID":"tt0100669","Type":"movie","Response":"True"}

所以只需使用带键和值作为参数的$ .each调用e.Title获取标题或循环到对象。第一个参数是属性名称（KEY），第二个参数是值。

$.each(e,function(key,value){
     result+="<p>"+ key + " : " + value +"</p>";         
});
