javascript - How to edit an element's text with React.js? -


i wanna edit p element's text when press edit button.

when click edit button, display textarea , keyed text alert can't put text p element.

what simple way react.js ?

jsfiddle

when press edit button, editing state changing , textarea shows up.the code below.

rendernormal: function() {     return (       <div>         <p>edit me</p>         <button onclick={this.edit}>edit</button>     </div>     )   },   renderform: function() {     return (       <div>          <textarea ref="newtext" defaultvalue="edit me"></textarea>         <button onclick={this.save}>save</button>     </div>     )   },   render: function() {     if (this.state.editing) {       return this.renderform()     } else {       return this.rendernormal()     }   }

you need store , retrieve text state variable. modifying state causes re-render, display updated text. copied jsfiddle... note i've added "text" property state

var mycom = react.createclass({   getinitialstate: function() {     return {       editing: false,       // ** initialize "text" property empty string here       text: ''     }   },   edit: function() {     this.setstate({       editing: true     })   },   save: function() {     var val = this.refs.newtext.value;     alert(val)     this.setstate({       // ** update "text" property new value (this fires render() again)       text: val,       editing: false     })   },   rendernormal: function() {     // ** render "state.text" inside <p> whether empty or not...     return (       <div>         <p>{this.state.text}</p>         <button onclick={this.edit}>edit</button>     </div>     )   },   renderform: function() {     return (       <div>          <textarea ref="newtext" defaultvalue="edit me"></textarea>         <button onclick={this.save}>save</button>     </div>     )   },   render: function() {     if (this.state.editing) {       return this.renderform()     } else {       return this.rendernormal()     }   } })  reactdom.render(   <div>   <mycom/>     <mycom/>     </div>,   document.queryselector(".box") )
