把value换成数字或者别的不是函数的对象 就报错 也不时的刷屏 幅度较小
livereload.js?snipver=1:637 Uncaught TypeError: __indexOf.call is not a function
换成f1就不挺的刷屏 幅度很大 连复制粘贴都不能做 没报错 输出
01.html:11 {writable: true, enumerable: false, configurable: true, value: ƒ}
01.html:22 {writable: true, enumerable: false, configurable: true, value: ƒ}
livereload.js?snipver=1:351 LiveReload protocol error (no supported protocols found) after receiving data: "undefined"..
如果把call改成别的就不会出错
在nodejs里 是正常的
