SelectTrigger dropdownMatchSelectWidth 属性的使用逻辑有问题,Safari浏览器在测试使用antdesign(3.10.2)的 Calendar组件时年份和月份的下拉选择列表显示不完整。

经查,问题出现在下面:
SelectTrigger.jsx 73行至81行
setDropdownWidth = () => {
if (!this.props.dropdownMatchSelectWidth) {
return;
} // 修复这个bug, 这句判断应去掉
const width = ReactDOM.findDOMNode(this).offsetWidth;
if (width !== this.state.dropdownWidth) {
this.setState({ dropdownWidth: width });
}
}
与SelectTrigger.jsx 159行至161行
if (this.state.dropdownWidth) {
popupStyle[widthProp] = ${this.state.dropdownWidth}px;
}
的逻辑冲突,导致dropdownMatchSelectWidth为false时,逻辑不正确,不能正确设置下拉列表宽度,dropdownMatchSelectWidth为true时,重复的判断。
初步学习react,经过个人测试,删除74至76行判断逻辑即可。不知修复方法是否妥当?
