写了一个简短的正则用作验证是否为手机号
var rg = new RegExp(/^[1][34578]\d{9}$/g); if(rg.test("15988888888")){ console.log(1); }else{ console.log(2); }
上面的代码直接在网页中运行，控制台返回2。而无论是在线测试，还是在控制台直接将代码输入，返回是1。为什么会出现这种情况（如下图）

var rg = /^[1][3|4|5|7|8]\d{9}$/g; if(rg.test("15988888888")){ console.log(1); }else{ console.log(2); }
