我在app.js 里面给Object原型添加了一个方法
onLaunch: function() { Object.prototype.foo = function(){ console.log("xxxx") }} |
然后新建了一个自定义组件，开发工具就一直报错，去掉上面这段代码就正常了，这是为什么？？
报错信息：
VM2026:1 thirdScriptError sdk uncaught third Error Cannot read property 'name' of undefined TypeError: Cannot read property 'name' of undefined at j (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:844772) at G (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:849707) at Object.t (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:851485) at yt (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:950556) at Bt (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:964920) at http://127.0.0.1:60556/appservice/components/coin/index.js:4:1 at require (http://127.0.0.1:60556/appservice/__dev__/WAService.js:1:971778) at <anonymous>:17:7 at HTMLScriptElement.scriptLoaded (http://127.0.0.1:60556/appservice/appservice?t=1551863441632:1133:21) at HTMLScriptElement.script.onload (http://127.0.0.1:60556/appservice/appservice?t=1551863441632:1145:20) |
目前暂不支持此功能。
是不支持在Object.prototype上添加方法么？其他原型呢，比如Array.prototype?
