JavaScript 函数优化：根据颜色等级设置行背景色

const setZHRowColor = (colorLevel: '' | '0' | '1' | '2') => { const colorMap = { '0': ZHRedRowColor, '1': ZHBlueRowColor, '2': ZHGreenRowColor };

if (colorMap[colorLevel]) { Object.assign(styleObj, { backgroundColor: colorMap[colorLevel] }); } }

或者更简洁的写法：

const setZHRowColor = (colorLevel: '' | '0' | '1' | '2') => { const colorMap = ['', ZHRedRowColor, ZHBlueRowColor, ZHGreenRowColor]; Object.assign(styleObj, { backgroundColor: colorMap[colorLevel] }); }
