在redux表单第一次提交后,关闭第二次提交按钮可以通过以下步骤实现:
isFormSubmitted
,初始值为false
。isFormSubmitted
字段设置为true
,表示表单已经提交过。isFormSubmitted
字段的值来控制第二次提交按钮的状态。如果isFormSubmitted
为true
,则禁用第二次提交按钮;如果为false
,则启用第二次提交按钮。以下是一个示例代码:
// Redux action
const submitForm = () => {
return {
type: 'SUBMIT_FORM',
};
};
// Redux reducer
const initialState = {
isFormSubmitted: false,
};
const formReducer = (state = initialState, action) => {
switch (action.type) {
case 'SUBMIT_FORM':
return {
...state,
isFormSubmitted: true,
};
default:
return state;
}
};
// React component
import { connect } from 'react-redux';
const FormComponent = ({ isFormSubmitted, submitForm }) => {
const handleSubmit = () => {
// Perform form submission logic
submitForm();
};
return (
<form onSubmit={handleSubmit}>
{/* Form fields */}
<button type="submit">Submit</button>
<button type="button" disabled={isFormSubmitted}>
Second Submit
</button>
</form>
);
};
const mapStateToProps = (state) => {
return {
isFormSubmitted: state.isFormSubmitted,
};
};
const mapDispatchToProps = {
submitForm,
};
export default connect(mapStateToProps, mapDispatchToProps)(FormComponent);
在上述示例中,isFormSubmitted
字段表示表单是否已经提交过。在表单提交的action中,调用submitForm
方法来更新redux的state中的isFormSubmitted
字段为true
。在渲染表单的组件中,根据isFormSubmitted
字段的值来控制第二次提交按钮的disabled
属性,从而实现关闭第二次提交按钮的效果。
