我已经解决了与我的问题相关的其他问题,但解决方案dint对我有用。这是我的ajax代码:
$.ajax({
url:'http://localhost:8080/items?callback=?',
type:'GET',
//the name of the callback function
jsonp: "jsonpcallback",
dataType:'jsonp',
success:function(data){
alert("hello" + data);
var length = data.length;
for(var i=0;i<length;i++){
var object = data[i];
var item = new Item(object.id,object.name,object.price,object.quantity);
$("#items-container").append(getItemHtml(item.id));
}
},
error:function(xhr,status,error){
alert(status);
}
});
这是我的回调函数:
function jsonpcallback(data){
console.log(data);
}
我收到一个名为parse错误的错误。有人可以告诉我哪里出错了???来自服务器的响应没有任何错误。
修改 添加了服务器响应:
[
{
"id": 1,
"name": "Snickers",
"price": 1.5,
"quantity": 7
},
{
"id": 2,
"name": "M&M's",
"price": 1.25,
"quantity": 8
},
{
"id": 3,
"name": "Almond Joy",
"price": 1.25,
"quantity": 11
},
{
"id": 4,
"name": "Milky Way",
"price": 1.65,
"quantity": 3
},
{
"id": 5,

"price": 1.75,
"quantity": 2
},
{
"id": 6,

"quantity": 5
},
{
"id": 7,

},
{

您的通话响应是JSON,而不是JSONP。它们不可互换。要将此集dataType
修复为'json'
,请删除对JSONP回调的引用。试试这个:
$.ajax({
url: 'http://localhost:8080/items',
type: 'GET',
dataType: 'json',
success: function(data) {
console.log(data); // only for testing
var length = data.length;
for (var i = 0; i < length; i++) {
var object = data[i];
var item = new Item(object.id, object.name, object.price, object.quantity);
$("#items-container").append(getItemHtml(item.id));
}
},
error:function(xhr, status, error) {
alert(status);
}
});
