我正在使用ajax进行跨域调用。但是我收到错误或Uncaught SyntaxError：意外的令牌：

I am making cross domain call with ajax. But i am getting error or Uncaught SyntaxError: Unexpected token :

<script src="code.jquery/jquery-latest.min.js" type="text/javascript"></script> <script type="text/javascript"> debugger; var prodID = "4220"; var txRef = "d38e92010"; var amt = "10000"; var hasKey = "60e0fac58c36accabc393172d6546320ecf00628fbba3a4bb4f9ef72c51f1c11e0c677fd9de5f7b9e45e2336871617fa845b24a6c85d541fc5a59726537d0abf"; var mackey = "199F6031F20C63C18E2DC6F9CBA7689137661A05ADD4114ED10F5AFB64BE625B6A9993A634F590B64887EEB93FCFECB513EF9DE1C0B53FA33D287221D75643AB"; var trgurl = "stageserv.interswitchng/test_paydirect/api/v1/gettransaction.json?productid=" + prodID + "&transactionreference=" + txRef + "&amount=" + amt + "&hash=" + hasKey + "&mackey=" + mackey + ""; $.ajax({ url: trgurl, dataType: 'JSONP', type: 'GET', contentType: 'application/json', crossDomain: true, success: function (data) { debugger; alert('success!' + data); }, error: function (data) { debugger; alert('success!' + data); }, complete: function (xhr, status) { debugger; } }); </script>

我的尝试： 我检查我的响应是json，我正在进行jsonp调用，这就是我收到错误的原因。但如果我让它Json调用我有跨域错误。我已经在我的asp项目全局文件中添加了跨域标题。

What I have tried: I check that my response is json and i am making jsonp call that's why i get that error. But if i make it Json call i had cross domain error. I have already added the cross domain headers in my asp project globle files.

推荐答案

.ajax（{ url：trgurl， dataType：' JSONP'，类型： ' GET'， contentType：' application / json'， crossDomain： true ，成功：函数（数据）{ 调试器; alert（' 成功！' +数据）; }，错误：功能（数据）{ 调试器; alert（' success！' + data）; }，完成： function （xhr，status）{ debugger ; } }）; < / script> .ajax({ url: trgurl, dataType: 'JSONP', type: 'GET', contentType: 'application/json', crossDomain: true, success: function (data) { debugger; alert('success!' + data); }, error: function (data) { debugger; alert('success!' + data); }, complete: function (xhr, status) { debugger; } }); </script>

之后我做了很多编码，并且知道只有你的代码必须是跨域但是目标域应该允许您进行跨域调用。请检查您的网址域是否允许您。 I have done lot of coding afterwards and came to knew only your code has to be cross domain but the target domain should allow you to make that cross domain call. Please check if your url domain allows you.
