为什么要在更新导航标签时判断 index == 0 这个条件??比较疑问
updateNav() {
this.navList = [];
const _this = this;
this.getTabs().forEach((pane, index) => {
_this.navList.push({
label: pane.label,
name: pane.name || index
});
if (!pane.name) {
pane.name = index;
}
if (index == 0) {
if (!_this.currentValue) {
_this.currentValue = pane.name || index;
}
}
});
this.updateStatus();
}

这么做是为了当tab组件没有设置activeKey或者activeKey为空时,默认显示第一个pane
