Javascript 位置250处JSON中的意外标记
我是javascript新手。我有一个表格，可以根据城市和邮政编码查找医生。但是，对于“城市”下拉列表，有一个特定的城市呈现错误。我不知道为什么对于那个特定的城市，它会抛出JSON错误。我唯一能想到的是，当传递值时，可能会有一个隐藏的值 代码如下：Javascript 位置250处JSON中的意外标记,javascript,json,coldfusion,Javascript,Json,Coldfusion,我是javascript新手。我有一个表格，可以根据城市和邮政编码查找医生。但是，对于“城市”下拉列表，有一个特定的城市呈现错误。我不知道为什么对于那个特定的城市，它会抛出JSON错误。我唯一能想到的是，当传递值时，可能会有一个隐藏的值 代码如下： <div class="form-group"> <SELECT name="proCity" class="form-control" id="city" placeholder="City" ng-model=

可能您的json字符串包含一些无效的Unicode字符 当这个测试完成时，我发现了下面的ASCII控件 作为内联JSON交付时可能出现问题的字符： 8232-行分隔符 8233-段落分隔符
在没有看到实际生成的字符串的情况下，我猜有些值包含需要转义的特殊字符。不要使用自己的JSON。而是使用有一些怪癖的JSON库或现有的JSON库。@Leigh我没有使用我自己的JSON。我正在使用angular.min.js版本。1.4.4为什么不使用angular的未统一版本并添加一个断点，以便您可以检查任何转换为JSON的内容。@JAEGERNINJA您使用的是自己的JSON，您正在使用查询创建它。。。选择{城市：['+stuff@tmp，1,1，+']}作为col，您应该使用数据创建一个coldfusion数组或结构，然后将其序列化为json。@KevinB是的，您是正确的，仍在学习中
