我用ajax请求本地的jsonp文件为什么会没反应
$.ajax({
type: "get",
url: "http://127.0.0.1:8080/jsonp.txt",
cache: false,
dataType: "jsonp",
jsonp:"fn1",
success: function(data) {
alert(data);
},
error: function() {
alert("出错");
}
});
----jsonp.txt----

建议楼主把json文件后缀改成.jsonp
var test =true;
$.ajax({
type: 'GET',
url: test ? 'resources/data/data3.jsonp' : url,
dataType: 'jsonp',
jsonp: false,
jsonpCallback: 'fn1',
data: {
id: pid
},
//timeout: 1000,
success: function (data, status, xhr) {
//
},
error: function () {
alert('error');
}
});说一个可能原因，要用服务器方式访问文件如127.0.0.1/test.html 而不是file://test.html
jsonp:"fn1" -> jsonpCallback: "fn1"
jsonp
类型: String
在一个JSONP请求中重写回调函数的名字。这个值用来替代在"callback=?"这种GET或POST请求中URL参数里的"callback"部分，比如{jsonp:'onJsonPLoad'}会导致将"onJsonPLoad=?"传给服务器。在jQuery 1.5，，设置jsonp选项为false，阻止了jQuery从加入"?callback"字符串的URL或试图使用"=?"转换。在这种情况下，你也应该明确设置jsonpCallback设置。例如, { jsonp: false, jsonpCallback: "callbackName" }
楼上提出了一个问题，还有一个问题就是你的JSONP文件是txt应该是html或者JS吧 不然怎么执行fn1函数，（window平台）你可以看一下http://blog.jobbole.com/18012/
