ReactJS - trigger event even if the same option is selected from select dropdown

How do I fire an event when an option is selected from dropdown in ReactJS. Currently I am using onChange but I need to fire an event even if same option is selected again.

Current code: 

<select name="select1" onChange={this.onChangeOption}>
    <option value='A'>Please select A...</option>
    <option value='B'>Please select B...</option>
    <option value='C'>Please select C...</option>
    <option value='D'>Please select D...</option>
</select>

I even tried adding onClick handler to option but that does not fire on click over the options as it works only with elements.

I know there are solutions using jquery by binding click event with option element, but need a solution in React. Dont want to include jQuery for only this requirement.

onchange reactjs events html javascript

This is trick, but if you need to fire function with the all changes, even with change of the same option, only one solution I know - use onClick and its detail:

class Select extends React.Component{
    onChangeOption(e){
        if (e.detail === 0){
            console.log(e.target.value);
        }
    }
    render(){
        return (
            <select name="select1" onClick={this.onChangeOption}>
                <option value='A'>Please select A...</option>
                <option value='B'>Please select B...</option>
                <option value='C'>Please select C...</option>
                <option value='D'>Please select D...</option>
            </select>
        )
    }
}

Hope this will solve your issue since we dont have anything bydefault in javascript. Just a work around. Its better not to do that math with better u call the callback everytime onclick is triggered.

let a = 0; //temporary variable - not requred until its particular
let onChangeOption = ()=>{
a = a+1; //not requred until its particular
if(a%2 == 0){// not requred until its particular
console.log("triggered ")
}
}
<select name="select1"  onclick="onChangeOption()">
    <option value='A'>Please select A...</option>
    <option value='B'>Please select B...</option>
    <option value='C'>Please select C...</option>
    <option value='D'>Please select D...</option>
</select>
