项目有个需求，用户便捷付款完成后自动退出小程序。没什么值得逗留。 但苦于找不到退出自己小程序的方法，请求大家告知。

使用外库 https://github.com/abdmob/x2js 解析xml2json. 在web端正常，移植到小程序就报错了。错误如下： thirdScriptError Cannot read property 'ActiveXObject' of undefined;at api getLocation success callback function TypeError: Cannot read property 'ActiveXObject' of undefined     at Object.parseXmlString (http://1074917368.appservice.open.weixin.qq.com/utils/xml2json.js:425:27)     at Object.xml_str2json (http://1074917368.appservice.open.weixin.qq.com/utils/xml2json.js:481:22)     at Object.SearchParkInfo (http://1074917368.appservice.open.weixin.qq.com/app.js:31:36)     at Function.success (http://1074917368.appservice.open.weixin.qq.com/app.js:44:17)     at Object.success (http://1074917368.appservice.open.weixin.qq.com/WAService.js:3:6898)     at http://1074917368.appservice.open.weixin.qq.com/WAService.js:4:8110     at Object.u [as 0.16555421337887521] (http://1074917368.appservice.open.weixin.qq.com/asdebug.js:1:14219)     at i (http://1074917368.appservice.open.weixin.qq.com/asdebug.js:1:13547)     at p (http://1074917368.appservice.open.weixin.qq.com/asdebug.js:1:4336)     at http://1074917368.appservice.open.weixin.qq.com/asdebug.js:1:5158 请问我该怎么解决啊？谢谢各位。
