element-ui的rules中正则表达式

rules: {
    loseEfficacyReason: [
          { required: true, message: '请输入原因', trigger: 'blur' },
          { min: 2, message: '请输入不少于2个字符', trigger: 'blur' },
          { pattern: /^[A-Za-z0-9u4e00-u9fa5]+$/, message: '不允许输入空格等特殊符号' }
      ]
}

　　

1. 大于0的数，最多可以有两位小数正则表达式

　　(^[1-9](d+)?(.d{1,2})?$)|(^d.d{1,2}$)

2. 利率：  ^([1-9]|[1-9]d)(.d{1,2})?$|(^0.[1-9])$|(^0.d[1-9])$

3. 利率正则表达式

　　^\d+(\.\d)?\d{0,1}%$

　　/^(([1-9]\d{0,9})|0)(\.\d{1,2})?%$/
