MDBSelect Selected Value cannot be set programmatically

Topic: MDBSelect Selected Value cannot be set programmatically

snh5499 priority asked 1 year ago

I am using the Google address validation and completion. Once the user enters the address parts in a single input text MBDInput (called address Search in screenshot) and selects the address that Google returns, I then want to auto-populate the address separate fields with the returned data. I use the "setState" to set all other inputs like address1, address2, city, zip country.

However, I am using the MDBSelect with US states loaded in as options. I use the "setState" to set the value of the MDBSelect however the selected item does not change to the correct selecteditem. Looks like the MDBSelect is turned into a HTML input and does not support the same attributes, methods, etc, as a HTML Select and I cannot find a way to change the selecteditem programmatically. Works fine if I click on the MDBSelect option and make the selection manually.

Also, have it working fine with a standard HTML Select element, so my logic is sound. You provide the onValueChange method where I can tie to function to then get the selected value. Just can't find a way to set. Is this not supported? If so, that is a major miss.

If there is no way to set the selecteditem programmatically, can you at least support a work around to mimic the mouseclick or keypress to manually select the proper selected item?

This is a screenshot with a HTML Select element that I reskinned to match the MDB look to match the other form elements. enter image description here The state form element is a standard Select that works. Your MDBSelect does not work.

<p>Yes, it does not work perfectly, so we're planning to make multiple fixes and changes to the MDBSelect and also improve the way of controlling our components in general.</p>

<p>Check my snippet, it may be useful in your case.</p>

<pre class="prettyprint"><code>import React, { useState, useCallback } from "react";
import { MDBBtn, MDBSelect } from "mdb-react-ui-kit";

export default function App() {
const [selectValue, setSelectValue] = useState([
  { text: "One", value: 1 },
  { text: "Two", value: 2 },
  { text: "Three", value: 3 },
  { text: "Four", value: 4 },
  { text: "Five", value: 5 },
  { text: "Six", value: 6 },
  { text: "Seven", value: 7 },
  { text: "Eight", value: 8 },
  { text: "Nine", value: 9 },
  { text: "Ten", value: 10 },
]);

const changeValue = useCallback((value) => {
  setSelectValue(
    selectValue.map((option) =>
      option.value === value ? { ...option, defaultSelected: true } : option
    )
  );
}, []);

return (
  <>
    <MDBSelect data={selectValue} />
    <MDBBtn onClick={() => changeValue(2)}>Change selected option</MDBBtn>
  </>
 );
}
</code></pre>

I got this to work with your snippet. Probably not the most eloquent solution so I look forward to the fix to the component. Please advise when it's available. Also there is a defect in the solution provided where the defaultSelected=true in the form if other states are selected. I fixed by just adding a defaultSelected: false on the other side of the inline if. to ensure only one option is in a true state.
