如何向 React JS 中动态创建的元素添加类？

Question

 {temp_array_beg.map((el,index) => ( <div key={index} className="subRenderButton"> <input type="button" value={el.i} className="paginationBtn" onClick= {this.handlePaginationClick.bind(this)} /> </div> ))}

Ihave tried Conditional Rendering of class but then all the rendered divs got the active class

Answer 1

 {temp_array.map((btn,index) => ( <div key={index} className="subRenderButton"> <input type="button"value={btn.i} className={["paginationBtn",buttonNumber == btn.i? "active":""].join(' ')} onClick={this.handlePaginationClick.bind(this)} /> </div> ))}

I have managed to solve the problem Thanks!
