JSON解析错误:错误的转义字符

我从控制器中的数据库中获取这些数据。我在保存和检索数据时使用了斜杠。请参阅控制器和php文件。我需要得到这个错误修复。我希望有人能指出我做错了什么。

{"records":[{"id":"425","name":"a","content":"a'b<br>a<br>b"},{"id":"426","name":"1","content":"1'2"}]} 

也请检查…Ionicnotepad.com/www这是我练习制作的。如果你保存的数据中有一个断点…无论在文本区显示什么
，都是不规则的。我什么都试过了。$sce, ng-bind-html, ng-sanitize，甚至是指令，如果你使用div和conteneditable。

//controller
