How get data from material-ui TextField, DropDownMenu components?

Question

I create form, I have several TextField, DropDownMenu material-ui components included, question is how I can collect all data from all TextFields, DropDownMenus in one obj and sent it on server. For TextField it has TextField.getValue() Returns the value of the input. But I can`t understand how to use it.

var React = require('react'),     mui = require('material-ui'),     Paper = mui.Paper,     Toolbar = mui.Toolbar,     ToolbarGroup = mui.ToolbarGroup,     DropDownMenu = mui.DropDownMenu,     TextField = mui.TextField,     FlatButton = mui.FlatButton,     Snackbar = mui.Snackbar;  var menuItemsIwant = [   { payload: '1', text: '[Select a finacial purpose]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsIcan = [   { payload: '1', text: '[Select an objective]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsHousing = [   { payload: '1', text: '[Select housing]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsIlive = [   { payload: '1', text: '[Select family mambers]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsLifestyle = [   { payload: '1', text: '[Select lifestyle]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsLifestyle2 = [   { payload: '1', text: '[Select savings]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var menuItemsIncome = [   { payload: '1', text: '[Select your yearly income]' },   { payload: '2', text: 'Every Night' },   { payload: '3', text: 'Weeknights' },   { payload: '4', text: 'Weekends' },   { payload: '5', text: 'Weekly' } ]; var Content = React.createClass({    getInitialState:

I want sent it on server in _handleClick method.

Answer 1

Add an onChange handler to each of your TextField and DropDownMenu elements. When it is called, save the new value of these inputs in the state of your Content component. In render, retrieve these values from state and pass them as the value prop. See Controlled Components.

var Content = React.createClass({      getInitialState: function() {         return {             textFieldValue: ''         };     },      _handleTextFieldChange: function(e) {         this.setState({             textFieldValue: e.target.value         });     },      render: function() {         return (             <div>                 <TextField value={this.state.textFieldValue} onChange={this._handleTextFieldChange} />             </div>         )     }  }); 

Now all you have to do in your _handleClick method is retrieve the values of all your inputs from this.state and send them to the server.

You can also use the React.addons.LinkedStateMixin to make this process easier. See Two-Way Binding Helpers. The previous code becomes:

var Content = React.createClass({      mixins: [React.addons.LinkedStateMixin],      getInitialState: function() {         return {             textFieldValue: ''         };     },      render: function() {         return (             <div>                 <TextField valueLink={this.linkState('textFieldValue')} />             </div>         )     }  });
