在React中,可以通过以下步骤来实现在单击提交按钮时重置表单:
import React, { useState } from 'react';
const FormComponent = () => {
const [formData, setFormData] = useState({
name: '',
email: '',
password: ''
});
const handleInputChange = (event) => {
const { name, value } = event.target;
setFormData({ ...formData, [name]: value });
};
const handleSubmit = (event) => {
event.preventDefault();
// 处理表单提交逻辑
// 重置表单
setFormData({
name: '',
email: '',
password: ''
});
};
return (
<form onSubmit={handleSubmit}>
<label>
Name:
<input
type="text"
name="name"
value={formData.name}
onChange={handleInputChange}
/>
</label>
<label>
Email:
<input
type="email"
name="email"
value={formData.email}
onChange={handleInputChange}
/>
</label>
<label>
Password:
<input
type="password"
name="password"
value={formData.password}
onChange={handleInputChange}
/>
</label>
<button type="submit">Submit</button>
</form>
);
};
export default FormComponent;
这样,在React中,当用户单击提交按钮时,会触发handleSubmit函数,该函数会阻止表单的默认提交行为,并重置表单的值为初始值,实现了在单击提交按钮时重置表单的功能。
