父组件接受不到子组件的值

Question

父组件

<my-render :multipleData='item' @division-data='divisionData'>
</my-render>

子组件

<script>
export default {
  name: 'my-render',
  props: {
    multipleData: {
      required: true
    }
  },
  render(h) {
    let _self = this;
    return h(
      'div',
      _self.blankFilling2.split('').map(d => {
        if (_self.target.find(t => t === d)) {
          return h('input', {
            style: {
              outlineStyle: 'none',
              padding: '5px 0px',
              width: '100px',
              fontSize: '12px',
              marginLeft: '10px',
              marginRight: '5px',

              blur: event => {
                _self.division.push(event.target.value);
              }

        } else {

      value: '',
      division: []
    };
  },
