React submit form on select change event

react get form values on submit
react label
react input component
select react
react submit form programmatically
react get multiple input value on button click
react hook form
react js dropdown selected value

I'm using ant design. I have a form. In that form I have submit button and select dropdown.

when I click submit button it triggers the form submit action.

I need to submit form and get values on select change event.

Code sandbox: https://codesandbox.io/s/xrpzw7wn8q

handleSubmit = e => {
    e.preventDefault();
    this.props.form.validateFields((err, values) => {
      if (!err) {
        console.log("Received values of form: ", values);
      }
    });
  };

You can add a callback to the onchange event of the Ant Design Select component, that could handle the form submit:

<Select
  allowClear
  onChange={
    (value) => {
      // your code to submit the form
    }
  }
>
  <Option key={1} value={1}>
    something 1
  </Option>
  <Option key={2} value={2}>
    something 2
  </Option>
</Select>

BUT from an UX perspective, if the submit button has to be present, it should be it to trigger submitting

Forms – React, In HTML, form elements such as <input> , <textarea> , and <select> typically maintain setState({value: event.target.value}); } handleSubmit(event) { alert('A name was <label> Name: <input type="text" value={this.state.value} onChange​={this. keeping track of the visited fields, and handling form submission, Formik is  In HTML, form data is usually handled by the DOM. In React, form data is usually handled by the components. When the data is handled by the components, all the data is stored in the component state. You can control changes by adding event handlers in the onChange attribute:

You can do something along those lines:

<Select allowClear onSelect={ (val, event) => this.handleSubmit(event) }>

Handling Forms in React, How to handle forms in a React application. When an element state changes in a form field managed by a component, we track it using the onChange attribute. class Form handleSubmit.bind(this) } handleChange(event) { this. createRef​() , and use that to get the value of it in the submit handler:. React, instead of using this selected attribute, uses a value attribute on the root select tag. This is more convenient in a controlled component because you only need to update it in one place. This is more convenient in a controlled component because you only need to update it in one place.

Add the onChange() or onSelect() from ant design select and access the values from the form in the callbacks.

state={
  selectValue : "default value",
  otherFormItemValue: "default other value"
}

handleSubmit = () => {
  serviceCallToSubmitForm(this.state.selectValue, this.state.otherFormItemValue);
}


//In the render() of component

<Select
  onChange={ 
//or onSelect
  (value) => {
    this.setState({selectValue: value}); 
    this.handleSubmit() 
    }
  }
>
  <Option key={1} value={"value 1"}>
    something 1
  </Option>
  <Option key={2} value={"value 2"}>
   something 2
  </Option>
</Select>

<Button onClick={this.handleSubmit}>Submit</Button>

Hope this helps and is clear enough.

The handleSubmit function is used to access the form values from the state and submit it. The onChange function call it used to : 1. Store the dropdown value in the state 2. call the handleSubmit function to actually submit in the same action [not recommended UX-wise]

How to Work with Forms, Inputs and Events in React, Capture changes of a form element using onChange() as they happen. 3. We can listen to the form submit event by creating an event listener  The form element itself can have events.

In HTML5 we have form elements like input,textarea, select they maintain there own internal state in the dom but in react we maintain the form elements state inside the component so that we can have full control over the form elements.
