使用JQuerys getJSON从其他域中提取时，我似乎无法使用我的JSON文件。我已将回调部分放在网址的末尾，但仍然没有任何乐趣。 Firebug告诉我它是一个跨域问题，这似乎有意义，好像我将json文件本地放在下面的代码中（不包括？jsoncallback =？工作正常）
继承人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;
}
});
}
});
}
JSON，我已经验证过。

答案 0 :(得分：12)
altCognito是正确的。这是一个有效的例子：
将此信息放在您打电话的页面顶部，在
中$.getJSON("http://www.yourotherdomain.com/testcross.php?jsoncallback=?",
function(data){
$('body').html(data.name).css("color","green");
});
和将返回内容的php：
$data = '{"name" : "hello world"}';
echo $_GET['jsoncallback'] . '(' . $data . ');';
答案 1 :(得分：11)
它没有返回回调函数，因此无法进行评估。
你的PHP代码应该有这样的东西：
echo $_GET['callback'] . '(' . $jsonData . ');';
哈哈，对不起，如果你使用的是php，那就是这种情况。
你想在你的javascript文件中使用它，并且你需要指定一个硬编码回调，因为它是一个静态列表。
