使用动态变量以获取状态值反应本机

Question

因此，我在EV1-EV15编号的初始状态中有多个对象，如何在循环中获取数据？这样的东西：

    for (var i = 0; i < 15; i++) {
        percentage = (0.5 / this.state.EVi.timeToFull) * 100;
        newSOC = Math.round((this.state.EVi.soc + percentage) * 10) / 10;
        if (newSOC >= 100) {
            newSOC =  100;
        }
        array.push(newSOC);
    }

Answer 1

this.state.EVi专门寻找this.state中称为EVi的属性。相反，将索引插入字符串中，并使用从状态获得适当的东西。

for (var i = 0; i < 15; i++) {
    const currentItem = `EV${i}`;
    percentage = (0.5 / this.state[currentItem].timeToFull) * 100;
    newSOC = Math.round((this.state[currentItem].soc + percentage) * 10) / 10;
    if (newSOC >= 100) {
        newSOC =  100;
    }
    array.push(newSOC);
}
