一、表单校验方式：
fileSort: [
{ required: true, message: "请输入排序", trigger: "blur" },
{ pattern: /^[1-9]\d*$/, message: '请输入正整数',trigger: 'blur' }
]二、el-input的type设置为number，然后去掉上下箭头
/deep/ input::-webkit-outer-spin-button,
/deep/ input::-webkit-inner-spin-button {
-webkit-appearance: none !important;
}
/deep/ input[type='number'] {
-moz-appearance: textfield !important;
}
