MDBSelect Array of Options - Get Value Errors

Hi there,

I have tried to reproduce your problem, but it looks like everything works fine. Please try the code presented above:

import React, { Component } from "react";
import { MDBSelect } from "mdbreact";


class App extends Component {
  state = {
    options: [
      {
        checked: false,
        disabled: false,
        icon: null,
        text: "Option one"
      },
      {
        checked: false,
        disabled: false,
        icon: null,
        text: "Option two"
      },
      {
        checked: true,
        disabled: false,
        icon: null,
        text: "Option three"
      },
      {
        checked: false,
        disabled: false,
        icon: null,
        text: "Option four"
      }
    ]
  };


  getDateRange = (value) =>{
    const dateRange = value[0];
    this.setState({dateRange}, () => console.log(this.state));
  }

  render(){
    return (
      <div>
        <Select menuItems={this.state.options} multiple={false}  search={false}  color="primary" label="Select" returnValue={this.getDateRange}   />
      </div>
    );
  }

};



const Select = (props) => {
  const { menuItems, multiple,  color, label, returnValue } = props;

  return (
    <div>
      <MDBSelect
        multiple={multiple}
        color={color}
        options={menuItems}
        getValue={returnValue}
        selected="Choose your option"
      />
      <label>{label}</label>
    </div>
  );
};

export default App;

Hello,

I did more research into this thanks to the information you provided. The code you provided works perfectly and I have been able to now reproduce the error consistently.

It seems that options need to be fed in from the state for some reason. Below is a code example that contains the same options in this.state.options and options2. If you update the code to contain menuItems={options2} instead of menuItems={options} you should be able to reproduce the error.

I am also console logging both of the values to compare the differences, at this time I can see none. I also ran JSON.stringify on both of the variables and compared the output text and there does not appear to be a difference.

import React, { Component } from "react";
import { MDBRow, MDBCol, MDBSelect } from 'mdbreact';

class Scans extends Component {
  constructor(props) {
    super(props);
    this.state = {
      options: [
        { checked: true, value: '7', text: '7 Days' },
        { value: '30', text: '30 Days' },
        { value: '90', text: '90 Days' },
        { value: 'custom', text: 'Custom Range' },
      ],
    };

    this.getDateRange = this.getDateRange.bind(this);
  }


  getDateRange(value) {
    const dateRange = value[0];
    this.setState({ dateRange });
  }

  render() {
    const { getDateRange } = this;
    const { options } = this.state;
    const options2 = [
      { checked: true, value: '7', text: '7 Days' },
      { value: '30', text: '30 Days' },
      { value: '90', text: '90 Days' },
      { value: 'custom', text: 'Custom Range' },
    ];

    console.log(options);
    console.log(options2);
    return (
      <div className="d-flex flex-column">
        <MDBRow>
          <MDBCol size="2">
            // Update this instance of options to options2 to produce error
            <Select menuItems={options} color="primary" label="Select" returnValue={getDateRange} />
          </MDBCol>
        </MDBRow>
      </div>
    );
  }

}

const Select = (props) => {
  const { menuItems, multiple, color, label, returnValue } = props;

  return (
    <div>
      <MDBSelect
        multiple={multiple}
        color={color}
        options={menuItems}
        getValue={returnValue}
        selected="Choose your option"
      />
      <label>{label}</label>
    </div>
  );
};


export default Scans;

Hello,

Thank you so much for explaining that. Having never run into it before I would have never guessed that was the issue. Again, thank you.

run into the exact same issue using #next as a version from gitlab, I'm using nextjs.

I was preparing the options in render and I run into maximum update depth ....

In componentDidMount I'm fetching my data and then programmatically build the options from the response.

example:

componentDidMount() {
let id = localStorage.getItem("_id");
axiosCallApi.get(`${apiUrl}/account/user/${id}`).then(response => {
  const user = response.data;
  const ranges = [
    {
      checked: user.comRange === 5000,
      disabled: false,
      icon: null,
      value: 5000,
      text: 5
    },
    {
      checked: user.comRange === 10000,
      disabled: false,
      icon: null,
      value: 10000,
      text: 10
    }
  ];
  this.setState({ user, ranges });
});
}

 handleDistanceChange = value => {
this.setState(
  update(this.state, {
    user: {
      comRange: {
        $set: value[0]
      }
    }
  })
);

};

  <MDBSelect
      color="primary"
      getValue={value =>
         this.handleDistanceChange(value)
      }
      options={this.state.ranges}
      selected="Choose your option"
  />

The issue comes from getValue, it seems it infinite runs if the options are inside render()

Hi @stathisntonas,

unfortunately, it's a bug, I've added it our TODO list - we will try to fix this as soon as possible. Sorry for the inconvenience.

Best regards,

Hi any news on fixing this?

I'm trying to make a custom selection where you choose a different outfit option and it will give a different price value on the second form dropdown

class Dashboard extends Component {
  constructor(props) {
    super(props);
    this.state = {
  outfits: "",
  outfits_budget: "",
  outfits14: "block",
  outfits17: "none",
  outfits2: "none",

Mid

        };

    this.onChange = this.onChange.bind(this);
    this.onSubmit = this.onSubmit.bind(this);
  }

  onChange(e) {
    this.setState({ [e.target.name]: e.target.value });
  }

  componentDidMount() {
    if (!this.props.auth.isAuthenticated) {
      this.props.history.push("/login");
    }
    if (this.props.auth.user.user_type == "1") {
      this.props.history.push("/admin");
    }
  }

  filterOutfits(e) {
    e.preventDefault();
    this.setState({ outfits: e.target.value, outfits_budget: "" });
    switch (e.target.value) {
      case "1 OUTFIT 4HRS":
        this.setState({
          outfits_budget: "",
          outfits14: "block",

Use react-select, it's free and simple. I'm sad to be a PRO user and not be able to use
