There are two ways to go about doing this.

Create a state in the constructor that contains the text input. Attach an onChange event to the input box that updates state each time. Then onClick you could just alert the state object.
handleClick: function() { alert(this.refs.myInput.value); },

First of all  you can t pass to alert second argument  use concatenation instead   alert  Input is     inputValue     Example  However in order to get values from input better to use states like this   x000D   x000D  var MyComponent   React createClass   x000D    getInitialState  function      x000D      return   input        x000D       x000D   x000D    handleChange  function e    x000D      this setState   input  e target value     x000D       x000D   x000D    handleClick  function     x000D      console log this state input   x000D       x000D   x000D    render  function     x000D      return   x000D         lt div gt  x000D           lt input type  text  onChange   this handleChange     gt  x000D           lt input x000D            type  button  x000D            value  Alert the text input  x000D            onClick  this handleClick  x000D            gt  x000D         lt  div gt  x000D         x000D      x000D      x000D   x000D  ReactDOM render  x000D     lt MyComponent   gt   x000D    document getElementById  container   x000D     x000D   lt script src  https   cdnjs cloudflare com ajax libs react 15 1 0 react min js  gt  lt  script gt  x000D   lt script src  https   cdnjs cloudflare com ajax libs react 15 1 0 react-dom min js  gt  lt  script gt  x000D   lt div id  container  gt  lt  div gt  x000D   x000D   x000D
