JS大数字转换为万

  //数字改变（加万位）
   function(value){
    const newValue = ['', '', '']
    let fr = 1000
    let num = 3
    let text1 = ''
    let fm = 1
    while (value / fr >= 1) {
      fr *= 10
      num += 1
      // console.log('数字', value / fr, 'num:', num)
    }
  if (num <= 8) { // 万
      text1 = parseInt(num - 4) / 3 > 1 ? '千万' : 'W'
      // tslint:disable-next-line:no-shadowed-variable
      fm = text1 === 'W' ? 10000 : 10000000
      if (value % fm === 0) {
        newValue[0] = parseInt(value / fm) + ''
      } else {
        newValue[0] = parseFloat(value / fm).toFixed(2) + ''
      }
      newValue[1] = text1
    }
    if (value < 1000) {
      newValue[0] = value + ''
      newValue[1] = ''
    }
    return newValue.join('')
  }
