Question

js input事件

比如，
<input type="number" id="thousandOfNum1" onKeyUp="thousandOfNUmber(this.value)" \>
<input type="number" id="thousandOfNum2" onKeyUp="thousandOfNUmber(this.value)" \>
<input type="number" id="thousandOfNum3" onKeyUp="thousandOfNUmber(this.value)" \>

thousandOfNUmber（value）{
value = value + 1;
...
}
thousandOfNUmber方法怎么使得input显示对应的值，id名称不固定。。。

Answer 1

function thousandOfNUmber(obj){
obj.value = obj.value*1 + 1;
}

<input type="number" id="thousandOfNum1" onKeyUp="thousandOfNUmber(this)" />
<input type="number" id="thousandOfNum2" onKeyUp="thousandOfNUmber(this)" />
<input type="number" id="thousandOfNum3" onKeyUp="thousandOfNUmber(this)" />
