js逻辑：

//窗体加载

window.onload = function () {

var onoffswitch = document.getElementById("toggle-button");

onoffswitch.checked = true;

}

//测试开始

function SwitchClick() {

var onoffswitch = document.getElementById("toggle-button");

var label = document.getElementById("batteryIconContent");

if (onoffswitch.checked) {

//调用后台

}

else {

//调用后台

}

}
