解决json包含html标签无法显示的问题

主要是将json无法识别的字符进行转义   
function dotran($str) {
        $str = str_replace('"','\\"',$str);
        $str = str_replace("\r\n",'\\r\\n',$str);
        $str = str_replace("\t",'\\t',$str);
        $str = str_replace("\\",'\\',$str);
        $str = str_replace("\b",'\\b',$str);
        return $str;
    }
这样返回的数据就可以正常显示，下面是转换后的内容：
jsontext='{"jqry":[{"id":"121","userid":"0","status":"1","filename":"","url":"333333333","title":"aaaaaaa","type":"WatchTV","seq":"1","remark":"remarktext","content":"<p>\\r\\n\\t<object classid=\\"clsid:d27cdb6e-ae6d-11cf-96b8-444553540000\\" codebase=\\"http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0\\"><param name=\\"quality\\" value=\\"high\\" /><param name=\\"movie\\" value=\\"
