javascript - React.js: onClick function from child to parent -

i used this article example (react way), not working me. please point me mistake, can't understand what's wrong.

this error see:

uncaught typeerror: this.props.onclick not function

here code:

// parent var senddocmodal = react.createclass({   getinitialstate: function() {     return {taglist: []};   },   render: function() {     return (       <div>         {           this.state.taglist.map(function(item) {             return (               <tagitem nameprop={item.name} idprop={item.id} onclick={this.handleremove}/>             )           })         }       </div>     )   },   handleremove: function(c) {     console.log('on remove = ', c);   } });  // child var tagitem = react.createclass({   render: function() {     return (       <span classname="react-tagsinput-tag">         <span>{this.props.nameprop}</span>         <a classname='react-tagsinput-remove' onclick={this.handleremove}></a>       </span>     )   },   handleremove: function() {     this.props.onclick(this);   } }); 

thanks in advance!

the issue this inside map callback not refer react component, hence this.handleremove undefined.

you can set this value explicitly passing second argument map:

this.state.taglist.map(function() {...}, this); 

now this inside callback refers same value this outside callback, namely senddocmodal instance.

this has nothing react, it's how javascript works. see how access correct `this` context inside callback? more info , other solutions.
