即使从服务器返回成功,我仍收到JSON parseerror.这是我的保存代码,其中总是运行fail()
@model.save()
.fail(=> @resetForm() )
.always (obj, error) ->
console.log obj
console.log obj.responseText
console.log JSON.parse(obj.responseText)
这是我的错误对象:
"parsererror"
"No conversion from text to http://api2.local/users/auth"
一些注意事项:
我正在使用Jquery 1.8.3和Backbone 0.9.9
服务器使用json正确响应-这是我的响应标头
Access-Control-Allow-Headers:origin, x-requested-with, content-type, accept
Access-Control-Allow-Methods:GET, POST, PUT, DELETE, OPTIONS

console.log JSON.parse(obj.responseText)正确地给了我一个JSON对象

解决方法:
Ahhhh-编程有时会很烦人.终于弄清楚了-谢谢大家的帮助,但这是一个简单的coffeescript编译问题
所以在我之前
$.ajaxPrefilter ( (options, originalOptions, jqXHR) ->
options.url = "#{ API_URL }" + options.url
)
编译后将返回options.url和$.ajaxPrefilter.无论出于何种原因,Jquery都会在ajaxPrefilter函数中将options.url设置为DataTypes argument.解决方案是返回false:
$.ajaxPrefilter \
(options, originalOptions, jqXHR) ->
options.url = "#{ API_URL }" + options.url
no
给出正确的编译版本
return $.ajaxPrefilter(function(options, originalOptions, jqXHR) {
options.url = ("" + API_URL) + options.url;
return false;
});
