javascript - How to use Variables in setState in JSX -

i use variable in setstate function in jsx file react.

how restructure code:

var name = e.target.name; if(name == "title"){     this.setstate({ title: e.target.value}); } else if(name == "date"){     this.setstate({ date: e.target.value}); } else if(name == "amount"){     this.setstate({ amount: e.target.value}); } 

into (so don't repeat myself)?

var name = e.target.name; this.setstate({ name: e.target.value}); 

the above syntax sets state of "name" , not value of "name" variable.

easy:

var newstate = {}; newstate[e.target.name] = e.target.value; this.setstate(newstate);
