javascript - Invariant Violation in React Render OR the proper way to iterate and return in React -

-

I am running into problems with constant renders in the {{ This.props.answers.map (function (reply, i) {return (

{answer.text} );}, this)}}}); Var QuizTaking = React.createClass ({componentDidMount: function () {}, render: function () {return (
div classname = 'submit' & gt; & lt; / div & gt; & lt; / div & gt;
)}})

me Ornamental violation: Answer: (): A valid response component should be returned. You can undefined, return an array or any other invalid object. Errors However, it works every time: 

  / ** @ jsx response DOM * / var TestIndex = React.createClass ({propTypes: {}, loadTest: function (i) {window.location .replace (this.props.tests [i] .url.replace (".json", "/ take "), Render: function () {return (
 
 {this.props.tests.map (function (Test, i) {return (
 
 )}});

I should understand what is happening here, and maybe this is the right way to do it.

You can not return many elements (like the Orange returned by the mapp function) from the Render function. Also, if you are missing a return statement, try it:

var response = response .createclass ({componentDidMount: function () {}, render: function () {return (& lt ; Div> gt; {this.props.answers.map (function (answer, i) {return (

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
