Form數據的收集和初始化

@Form.create({
    mapPropsToFields: (props) => {

        const keys = Object.keys(formData);
        const newFormData = {};

            newFormData[keys[i]] = Form.createFormField({
                ...formData[keys[i]],
                value: formData[keys[i]] && formData[keys[i]].value,
            });
        }
        return newFormData;
    },
    onFieldsChange(props, fields) {
        let baseKey = ['deptcode', 'reportYear', 'reportMonth', 'deptname', 'deptPeopleNow', 'deptPeoplePre', 'certificatePeopleNow', 'certificatePeoplePre', 'premiumTotal', 'premiumPre', 'turnoverTotal', 'turnoverPre', 'profitNow', 'profitPre'];
        const keys = Object.keys(fields);
        let key = keys[0]; // 基本信息中的key / property / life
        let newFields = {};
        if (baseKey.includes(key)) { // 對於普通的formItem
            props.onFormChange(fields);
        } else { // 成組增長的formItem
            let subFields = fields[key] || {};
            let subFieldsKey = Object.keys(subFields)[0];

                let realyFieldsKey = Object.keys(arr)[0];
                if (!realyFieldsKey) return;
                let value = arr[realyFieldsKey];

對於modal中的表單

經過modalVisible控制modal是否可見,以及modal的加載和銷燬.對於modal中的數據,能夠經過initialValue進行初始化

{modalVisible ? (<EditModal
    formData={formData}
    closeModal={this.closeModal}
    modalType={modalType}
    modalVisible={modalVisible}
    handlePageSearch={this.handlePageSearch}
    insuranceCityData={insuredCityList}
    issuingTypeList={issuingTypeList}
    licensedCityData={cities}
/>) : null}

<FormItem {...modalFormItemLayout} label="城市">
    {
        getFieldDecorator('cityId', {
            initialValue: cityId && cityId + '',
            rules: [{ required: true, message: '請選擇城市' }],
            onChange: (value, options) => {
                setFieldsValue({
                    'cityName': options.props.children,
                });
            },
        })(<Select
            allowClear
            showSearch
            placeholder="請選擇"
            onChange={this.handleCityChange}
            defaultActiveFirstOption={false}
            optionFilterProp="children"
            >
            {
                getSelectOptions([{ cityId: -1 , cityName: '所有' }], cityData, ['cityId', 'cityName'])
            }

Form-批量增長一組表單

經過getFieldDecorator進行裝飾時, 賦值爲number[${k}]或number{k},他們對應的值分別爲number[k]和fields[number{k}];

<FormItem>
    {
        getFieldDecorator(`number[${k}]`)(<Select
            placeholder="請選擇"
            defaultActiveFirstOption={false}
            style={config.selectStyle}
            disabled={!canEdit}
        >
            <Option value='0'>0-0</Option>
            <Option value='1'>0-1</Option>
        </Select>)
    }
</FormItem>
