RegExp对象—应用案例

长度为10位，最多带两位小数的正则

    {
        pattern: /^(-)?[0-9]((\d)+)?(\.(\d)+)?$/,
        message: "请输入数字",
        trigger: "blur"
    },
    {
        pattern: /^[0-9]((\d)+)?(\.(\d)+)?$/,
        message: "请输入非负数",
        trigger: "blur"
    },
    {
        pattern: /^[0-9](\d){0,9}?(\.(\d+)?)?$/,
        message: "整数部分长度不能超过10位",
        trigger: "blur"
    },
    {
        pattern: /^[0-9](\d){0,9}?(\.(\d+))?$/,
        message: "请输入正确的数字格式",
        trigger: "blur"
    },
    {
        pattern: /^[0-9](\d){0,9}?(\.(\d){1,2})?$/,
        message: "请最多保留两位小数点",
        trigger: "blur"
    }

长度10位的整数

    {
        pattern: /^[1-9](\d+)?$|^0$/,
        message: "请输入整数",
        trigger: "blur"
    },
    {
        pattern: /^[1-9](\d){0,9}?$|^0$/,
        message: "长度不能超过10位",
        trigger: "blur"
    }

或

    {
        pattern: /^[1-9][0-9]*$|^0$/,
        message: "请输入格式正确的整数"
    },
    {
        pattern: /^[1-9][0-9]{0,9}?$|^0$/,
        message: "长度不能超过10位",
        trigger: "blur"
    }

百分比的整数

    {
        pattern: /^[1-9][0-9]*$|^0$/,
        message: "请输入格式正确的整数"
    },
    {
        pattern: /^[1-9][0-9]{0,8}?$|^0$/,
        message: "长度不能超过9位",
        trigger: "blur"
    },
    {
        pattern: /^100$|^[1-9]\d$|^\d$/,
        message: "请输入0至100的整数",
        trigger: "blur"
    }
