1. Usage scenarios

This example describes how to format and verify bank card numbers on the YIDA form page.

2. Implement functions

2.1 Create form page

2.2 page configuration

(1) configure variables

As shown in the following figure:

(2) copy the following code to Page JS

Note that the following unique identifier is modified.

export function onChange({ value }) {
  //防止循环调用
  if (!this.state.fixed) {
    this.setState({
      fixed: true,
    });
    const formatted = value.replace(/D/g, '').replace(/....(?!$)/g, '$& ')
    this.$('textField_l9pdvjxn').setValue(formatted)
    this.setState({
      fixed: false,
    });
  }
}

export function customValidation(num) {
  // 去除空格
  num = (num + '').replace(/D+/g, '')
  const regExp = /^([1-9])(d{15}|d{18})$/
  // 校验非0开始及长度
  if (!regExp.test(num)) {
    return false
  }
  num = num.split('').reverse();
  let total = 0
  for (let i = 0; i < num.length; i++) {
    num[i] = parseInt(num[i]);
    total += i % 2 ? 2 * num[i] - (num[i] > 4 ? 9 : 0) : num[i];
  }
  if (total === 0) {
    return false;
  }
  return (total % 10) === 0;
}

(3) event binding

function customValidation(num) {
  return this.customValidation(num);
}
