判断设备是否在充电
navigator.getBattery().then(function(battery){
if(battery.charging) {
alert("电池正在充电");
}else {
alert("电池没有充电");
}
})
获取设备电量
navigator.getBattery().then(function(battery){
alert("电池电量" + battery.level * 100 + "%");
})
电池状态监听器
navigator.getBattery().then(function(battery){
battery.addEventListener("chargingchange", function() {
console.log("电池状态:", battery.charging);
}) battery.addEventListener("levelchange", function() {
console.log("电池电量:", battery.level * 100 + "%");
}) battery.addEventListener("chargingtimechange", function() {
console.log("电池充满还需:", battery.chargingTime + "秒");
}) battery.addEventListener("dischargingtimechange", function() {
console.log("电池电量还能支撑:", battery.dischargingTime + "秒");
})
})
