React JS reference function in another component

javascript, reactjs

Solution

You could accomplish this by creating a parent component that is responsible for managing the state and then just push the state down to the sub-components as props.

/** @jsx React.DOM */

var Inputs = React.createClass({

    render: function () {
        var items = [];
        var inputs;
        for (var i = 0; i < this.props.count; i++) {
            items.push( <input type="text" name={[i]} />);
            items.push(<br />);
        }
        return ( 
            <div className = "col-md-9"> 
                <form action = "/" method = "post" name = "form1"> 
                    {items} 
                    <input type="submit" className="btn btn-success" value = "Submit Form" />            
                </form>
            </div> 
       );
    }
});

var Add = React.createClass({
    render: function () {
        return (<input type = "button" className="btn" value="Add an Input" onClick={this.props.fnClick}/> );
  }
});

var Parent = React.createClass({
    getInitialState: function(){
        return {count:1}
    },
    addInput: function(){
        var newCount = this.state.count + 1;
        this.setState({count: newCount});
    },
    render: function(){
        return (
            <div>
                <Inputs count={this.state.count}></Inputs>
                <Add fnClick={this.addInput}/>
            </div>
        );
    }
});

React.renderComponent(<Parent></Parent> , document.body);

Problem

I'm trying to get a button rendered through another component to reference and/or influence the state of a different component. ``` var Inputs = React.createClass({ getInitialState: function(){ return {count: 1}; }, add: function(){ this.setState({ count: this.state.count + 1 }); }, render: function(){ var items = []; var inputs; for (var i = 0; i < this.state.count; i++){ items.push(<input type="text" name={[i]} />); items.push(<br />); } return ( <div className="col-md-9"> <form action="/" method="post" name="form1"> {items} <input type="submit" className="btn btn-success" value="Submit Form" /> </form> </div> ); } }); ``` I want to write a new component that will be able to access the add function in Inputs. I tried to reference it directly with `Inputs.add` like this: ``` var Add = React.createClass({ render: function(){ return ( <input type="button" className="btn" value="Add an Input" onClick={Inputs.add} /> ); } }); ``` But that didn't work. How would I be able to access a component's functions through another component, or influence the state of a component through another component? Thanks.
