var arr = [ { email: '', role: 'normal', password: '' },
  { email: '', role: 'normal', password: '' },
  { email: '', role: 'normal', password: '' },
  { email: '', role: 'normal', password: '' },
  { email: '', role: 'normal', password: '' },
  { email: '', role: 'normal', password: '' } ]

arr.forEach(o => { o.password =Math.random() })

output :[ { email: '', role: 'normal', password: 0.16326031488429638 },
  { email: '', role: 'normal', password: 0.4941354999549721 },
  { email: '', role: 'normal', password: 0.6802056630925 },
  { email: '', role: 'normal', password: 0.5038916232454755 },
  { email: '', role: 'normal', password: 0.5232000715886489 },
  { email: '', role: 'normal', password: 0.1599782533612224 } ]

当使用 for 创建一个 对象数组

 var obj  = {
    email: '1',
    role: 'normal',
    password: ''
},array=[]

for(let i =0;i<6;i++){
     array.push(function(){
         obj.password = Math.random()
         return obj
     })   
}

output: [ { email: '1', role: 'normal', password: 0.4311454570811686 },
  { email: '1', role: 'normal', password: 0.4311454570811686 },
  { email: '1', role: 'normal', password: 0.4311454570811686 },
  { email: '1', role: 'normal', password: 0.4311454570811686 },
  { email: '1', role: 'normal', password: 0.4311454570811686 },
  { email: '1', role: 'normal', password: 0.4311454570811686 } ]

My problem is that in the second object array generated by for, the value of obj.password is not repeated
