我正在封裝我的表單以提供自動驗證(我不想使用redux-form)。React Redux和副作用解釋
我想傳遞一個onsubmit處理必須在表單中的每個輸入進行驗證之後被解僱:但我怎麼等待form.valid屬性來包裝提交被解僱後,變成真正的& &?我在這裏錯過了一些邏輯!
//in my Form.js hoc wrapping the forms
@autobind
submit(event) {
event.preventDefault();
this.props.dispatch(syncValidateForm({ formName: this.props.formName, form: this.props.form }));
// ==> what should I do here? Here I know submit button was pressed but state is not updated yet with last dispatch result reduced!
//if(this.props.form.valid)
// this.props.submit();
}
render() {
return (
<form name={this.props.formName} onSubmit={this.submit}>
{ this.props.children }
</form>
);
//action.js validating given input
export const syncValidateInput = ({ formName, input, name, value }) => {
let errors = {<computed object with errors>};
return { type: INPUT_ERRORS, formName, input, name, value: errors };
};
//action.js validating every input in the form
export const syncValidateForm = ({ formName, form }) => {
return dispatch => {
for(let name in form.inputs) {
let input = form.inputs[name];
dispatch(syncValidateInput({ formName, input, name: input.name, value: input.value }));
}
};
};
//in my reducer I have
case INPUT_ERRORS:
let errors = value;
let valid = true;
let errorText = '';
_.each(errors, (value, key) => {
if(value) {
valid = false;
errorText = `${errorText}${key}\n`;
}
});
form.inputs[name].errors = errors;
form.inputs[name].valid = valid;
form.inputs[name].errorText = errorText;
_.each(form.inputs, (input) => form.valid = !!(form.valid && input.valid));
return state;
幫助!
