错误的基于名称属性的对象数组

我有一个包含状态和名称属性的对象数组。 我想要使​​用他们的name属性使用下面的代码：

 array = array.sort(function(a,b){ return a.name - b.name }); 

但是它不会返回正确的sorting数组。 这里有一个片段，你可以看到它的行动：

 var array = [{"name":"whoopsie","status":"active"},{"name":"acpid","status":"active"},{"name":"apache2","status":"active"},{"name":"apparmor","status":"active"},{"name":"apport","status":"active"},{"name":"avahi-daemon","status":"active"},{"name":"bluetooth","status":"active"},{"name":"cron","status":"active"},{"name":"cups","status":"active"},{"name":"cups-browsed","status":"active"},{"name":"dbus","status":"active"},{"name":"grub-common","status":"active"},{"name":"irqbalance","status":"active"},{"name":"kmod","status":"active"},{"name":"lightdm","status":"active"},{"name":"lvm2-lvmetad","status":"active"},{"name":"lvm2-lvmpolld","status":"active"},{"name":"apache-htcacheclean","status":"active"},{"name":"network-manager","status":"active"},{"name":"networking","status":"active"},{"name":"postfix","status":"active"},{"name":"procps","status":"active"},{"name":"resolvconf","status":"active"},{"name":"rsyslog","status":"active"},{"name":"smartmontools","status":"active"},{"name":"smbd","status":"active"},{"name":"speech-dispatcher","status":"active"},{"name":"ssh","status":"active"},{"name":"thermald","status":"active"},{"name":"tlp","status":"active"},{"name":"udev","status":"active"},{"name":"ufw","status":"active"},{"name":"lvm2-lvmpolld","status":"inactive"},{"name":"mysql","status":"active"},{"name":"alsa-utils","status":"inactive"},{"name":"x11-common","status":"inactive"},{"name":"apache-htcacheclean","status":"inactive"},{"name":"avahi-daemon","status":"inactive"},{"name":"console-setup.sh","status":"inactive"},{"name":"cryptdisks","status":"inactive"},{"name":"cryptdisks-early","status":"inactive"},{"name":"cups-browsed","status":"inactive"},{"name":"grub-common","status":"inactive"},{"name":"hwclock.sh","status":"inactive"},{"name":"kerneloops","status":"inactive"},{"name":"keyboard-setup.sh","status":"inactive"},{"name":"laptop-mode","status":"inactive"},{"name":"lvm2","status":"inactive"},{"name":"lvm2-lvmetad","status":"inactive"},{"name":"anacron","status":"inactive"},{"name":"network-manager","status":"inactive"},{"name":"nmbd","status":"inactive"},{"name":"plymouth","status":"inactive"},{"name":"plymouth-log","status":"inactive"},{"name":"pppd-dns","status":"inactive"},{"name":"prometheus","status":"inactive"},{"name":"rsync","status":"inactive"},{"name":"samba","status":"inactive"},{"name":"samba-ad-dc","status":"inactive"},{"name":"saned","status":"inactive"},{"name":"speech-dispatcher","status":"inactive"},{"name":"unattended-upgrades","status":"inactive"},{"name":"uuidd","status":"inactive"},{"name":"unattended-upgrades","status":"active"}]; array = array.sort(function (a,b) { return a.name - b.name }) console.log(array.map(function(i){ return i.name })) 

这是输出：

我在nodejs中运行这个代码

Answer 1

你正在通过expression式a.name - b.name进行sorting，这对于你的数据总是NaN 。

如果您尝试按字母顺序sorting，则可能需要查看此文章：
Javascript – 在数组的一个属性上按字母顺序排列对象

 var array = [{"name":"whoopsie","status":"active"},{"name":"acpid","status":"active"},{"name":"apache2","status":"active"},{"name":"apparmor","status":"active"},{"name":"apport","status":"active"},{"name":"avahi-daemon","status":"active"},{"name":"bluetooth","status":"active"},{"name":"cron","status":"active"},{"name":"cups","status":"active"},{"name":"cups-browsed","status":"active"},{"name":"dbus","status":"active"},{"name":"grub-common","status":"active"},{"name":"irqbalance","status":"active"},{"name":"kmod","status":"active"},{"name":"lightdm","status":"active"},{"name":"lvm2-lvmetad","status":"active"},{"name":"lvm2-lvmpolld","status":"active"},{"name":"apache-htcacheclean","status":"active"},{"name":"network-manager","status":"active"},{"name":"networking","status":"active"},{"name":"postfix","status":"active"},{"name":"procps","status":"active"},{"name":"resolvconf","status":"active"},{"name":"rsyslog","status":"active"},{"name":"smartmontools","status":"active"},{"name":"smbd","status":"active"},{"name":"speech-dispatcher","status":"active"},{"name":"ssh","status":"active"},{"name":"thermald","status":"active"},{"name":"tlp","status":"active"},{"name":"udev","status":"active"},{"name":"ufw","status":"active"},{"name":"lvm2-lvmpolld","status":"inactive"},{"name":"mysql","status":"active"},{"name":"alsa-utils","status":"inactive"},{"name":"x11-common","status":"inactive"},{"name":"apache-htcacheclean","status":"inactive"},{"name":"avahi-daemon","status":"inactive"},{"name":"console-setup.sh","status":"inactive"},{"name":"cryptdisks","status":"inactive"},{"name":"cryptdisks-early","status":"inactive"},{"name":"cups-browsed","status":"inactive"},{"name":"grub-common","status":"inactive"},{"name":"hwclock.sh","status":"inactive"},{"name":"kerneloops","status":"inactive"},{"name":"keyboard-setup.sh","status":"inactive"},{"name":"laptop-mode","status":"inactive"},{"name":"lvm2","status":"inactive"},{"name":"lvm2-lvmetad","status":"inactive"},{"name":"anacron","status":"inactive"},{"name":"network-manager","status":"inactive"},{"name":"nmbd","status":"inactive"},{"name":"plymouth","status":"inactive"},{"name":"plymouth-log","status":"inactive"},{"name":"pppd-dns","status":"inactive"},{"name":"prometheus","status":"inactive"},{"name":"rsync","status":"inactive"},{"name":"samba","status":"inactive"},{"name":"samba-ad-dc","status":"inactive"},{"name":"saned","status":"inactive"},{"name":"speech-dispatcher","status":"inactive"},{"name":"unattended-upgrades","status":"inactive"},{"name":"uuidd","status":"inactive"},{"name":"unattended-upgrades","status":"active"}]; array = array.sort(function (a,b) { var textA = a.name.toUpperCase(); var textB = b.name.toUpperCase(); return (textA < textB) ? -1 : (textA > textB) ? 1 : 0; }) console.log(array.map(function(i){ return i.name }))

使用localCompare按字母顺序排列。

 var array = [{"name":"whoopsie","status":"active"},{"name":"acpid","status":"active"},{"name":"apache2","status":"active"},{"name":"apparmor","status":"active"},{"name":"apport","status":"active"},{"name":"avahi-daemon","status":"active"},{"name":"bluetooth","status":"active"},{"name":"cron","status":"active"},{"name":"cups","status":"active"},{"name":"cups-browsed","status":"active"},{"name":"dbus","status":"active"},{"name":"grub-common","status":"active"},{"name":"irqbalance","status":"active"},{"name":"kmod","status":"active"},{"name":"lightdm","status":"active"},{"name":"lvm2-lvmetad","status":"active"},{"name":"lvm2-lvmpolld","status":"active"},{"name":"apache-htcacheclean","status":"active"},{"name":"network-manager","status":"active"},{"name":"networking","status":"active"},{"name":"postfix","status":"active"},{"name":"procps","status":"active"},{"name":"resolvconf","status":"active"},{"name":"rsyslog","status":"active"},{"name":"smartmontools","status":"active"},{"name":"smbd","status":"active"},{"name":"speech-dispatcher","status":"active"},{"name":"ssh","status":"active"},{"name":"thermald","status":"active"},{"name":"tlp","status":"active"},{"name":"udev","status":"active"},{"name":"ufw","status":"active"},{"name":"lvm2-lvmpolld","status":"inactive"},{"name":"mysql","status":"active"},{"name":"alsa-utils","status":"inactive"},{"name":"x11-common","status":"inactive"},{"name":"apache-htcacheclean","status":"inactive"},{"name":"avahi-daemon","status":"inactive"},{"name":"console-setup.sh","status":"inactive"},{"name":"cryptdisks","status":"inactive"},{"name":"cryptdisks-early","status":"inactive"},{"name":"cups-browsed","status":"inactive"},{"name":"grub-common","status":"inactive"},{"name":"hwclock.sh","status":"inactive"},{"name":"kerneloops","status":"inactive"},{"name":"keyboard-setup.sh","status":"inactive"},{"name":"laptop-mode","status":"inactive"},{"name":"lvm2","status":"inactive"},{"name":"lvm2-lvmetad","status":"inactive"},{"name":"anacron","status":"inactive"},{"name":"network-manager","status":"inactive"},{"name":"nmbd","status":"inactive"},{"name":"plymouth","status":"inactive"},{"name":"plymouth-log","status":"inactive"},{"name":"pppd-dns","status":"inactive"},{"name":"prometheus","status":"inactive"},{"name":"rsync","status":"inactive"},{"name":"samba","status":"inactive"},{"name":"samba-ad-dc","status":"inactive"},{"name":"saned","status":"inactive"},{"name":"speech-dispatcher","status":"inactive"},{"name":"unattended-upgrades","status":"inactive"},{"name":"uuidd","status":"inactive"},{"name":"unattended-upgrades","status":"active"}]; array = array.sort(function (a,b) { return a.name.localeCompare(b.name) }) console.log(array.map(function(i){ return i.name }))
