未捕获的SyntaxError：意外的令牌：在jquery mobile ajax调用中 [英] Uncaught SyntaxError: Unexpected token : in jquery mobile ajax calling
问题描述
我想用jquery mobile获取web服务，我在jquery上调用ajax调用了一个示例，我得到了这个错误Uncaught SyntaxError：Unexpected token：。我的代码在下面
< ！DOCTYPE html >
< html >
< head >
< span class =code-keyword>< meta charset = utf-8 / >
< meta name = viewport content < span class =code-keyword> = width = device-width，initial-scale = 1 / >
< title > webservices示例< ; / title >
< link rel = 样式表 href = jquery.mobile-1.1.0.css / >
< 链接 rel = stylesheet href = my.css / >
< script src = https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js > < / script >
< script < span class =code-attribute> type = text / javascript >
$（document）.ready（function（）{
$ .ajax （{
类型：GET，
url：http://shoperola.com/Restaurant/foodysrest/sample，
crossDomain：true，
contentType：application / json; charset = utf-8，
data：{}，
dataType：jsonp，
success：function（data）{
alert（data）;
}，
错误：函数（数据）{
alert（处理错误-----+ data.status）;
}
}）;
}）
< / script >
< / head >
< / html < span class =code-keyword>>
i试图将jsonp更改为js在，然后我得到了
XMLHttpRequest无法加载http://shoperola.com/Restaurant/foodysrest/sample？{}。请求的资源上不存在Access-Control-Allow-Origin标头。原因'http：//< localhost>：8088'因此不允许访问。
当我执行此代码时，我得到警告处理错误----- 200这条消息。我怎么能解决这个问题？200是成功状态消息仍然出错。我尝试在上面的ajax调用中删除crossDomain，contentType和data属性，仍然是结果是一样的。

你的dataType应该是json，而不是jsonp。
但这只会消除意外的令牌错误，你还是由于CORS问题，将无法读取Web服务...
I want to get the web services with jquery mobile,i wrote a sample example on ajax calling in jquery,i got this error" Uncaught SyntaxError: Unexpected token : ".My code is below
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>webservices example </title>
<link rel="stylesheet" href="jquery.mobile-1.1.0.css" />
<link rel="stylesheet" href="my.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$.ajax({
type:"GET",
url:"http://shoperola.com/Restaurant/foodysrest/sample",
crossDomain: true,
contentType: "application/json; charset=utf-8",
data: "{}",
dataType: "jsonp",
success: function(data) {
alert(data);
},
error: function(data) {
alert("Error in Processing-----" + data.status);
}
});
})
</script>
</head>
</html>
i tried to change jsonp to json,then i got
" XMLHttpRequest cannot load http://shoperola.com/Restaurant/foodysrest/sample?{}. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://<localhost>:8088' is therefore not allowed access".
when i execute this code,I got alert with "Error in Processing-----200" this message.How can i slove this problem? 200 is success status message still getting error. I tried removing crossDomain,contentType and data attributes in the above ajax call,still the result was same.
(document).ready(function() {
.ajax({ type:"GET", url:"http://shoperola.com/Restaurant/foodysrest/sample", crossDomain: true, contentType: "application/json; charset=utf-8", data: "{}", dataType: "jsonp", success: function(data) { alert(data); }, error: function(data) { alert("Error in Processing-----" + data.status); } }); }) </script> </head> </html>

YourdataTypeshould bejson, notjsonp.
But that will only remove the unexpected token error, you still will not be able to read the web service because of CORS problem...
