发件人:88001223<\/font><\/p>

发件时间:2009-5-26 12:32:7<\/font><\/p>","msgSubject":"send mesgddddd","sender":"88001223","status":"success","senderId":"6562","sign":"unread","msgId":"637","activityId":"0","receiver":"88001223","receiverId":"6562","label":"common","msgType":"site","source":"msg","priority":"normal","sendDate":"2009-06-26"},{"typeSign":"site_read","msgContent":"beyond 1983---1993","msgSubject":"反复反复反复反复反复发放","sender":"88001231","status":"success","senderId":"6569","sign":"read","msgId":"636","activityId":"0","receiver":"88001223","receiverId":"6562","label":"common","msgType":"site","source":"msg","priority":"normal","sendDate":"2009-06-22"}]}';[/code]
要把内容中的【\"】 替换成[\\"] ，原因是在Ext.util.decode(msglistValue );回报【无法解析字符】。
球各位达人 多多帮忙 ，着急啊

这个地方，正在表达式是不起作用的，因为在字符串里面，并没有\，\"实际上就等于"。你要做的是对由FCKEditor生成的HTML内容进行转义，把<、>、和"都进行转义，变成<、>和&quot；这样的话，再变成JSON的时候就不会出问题了。
