#是否安装某个软件

baidumap://        百度云

var isInstall = isInstallApp.isInstallApp(url);
uni.showToast({
    title: JSON.stringify(isInstall),
    icon: 'none'
})

#打开某个软件

plus.runtime.openURL(appurl, function(res) {
        console.log(res);
});

#使用浏览器打开网址

plus.runtime.openURL(url)

#获取APPID

uni.showToast({
    title: plus.runtime.appid,
    icon: 'none',
    duration: 3000

#设置APP角标

number：提示数据，0则清空
plus.runtime.setBadgeNumber(number);

#打开文件

//相对路径
plus.runtime.openFile('/static/zsdx.pdf')

#发出蜂鸣

number:次数
plus.device.beep(number)

#震动

plus.device.vibrate();//默认500ms
uni.vibrate({
    success: function () {
        console.log('success');
    }
});
//400ms
uni.vibrateLong({
    success: function () {
        console.log('success');
    }
});
//15ms
uni.vibrateShort({
    success: function () {
        console.log('success');

});
iOS上只有长震动，没有短震动
iOS上需要手机设置“打开响铃时震动”或“静音时震动”，否则无法震动
vibrate只适用于钉钉小程序、支付宝小程序
