方式一调用：
window.protocolCheck("hyvss://", () => { alert('检测到当前电脑未安装,确认是否下载！') });方式二（Vue中使用）：
export function openUrlWithInputTimeoutHack(url, failCb, successCb) {
let target = document.createElement('input')
target.style.width = '0'
target.style.height = '0'
target.style.position = 'fixed'
target.style.top = '0'
target.style.left = '0'
document.body.appendChild(target)
target.focus();
var handler = _registerEvent(target, "blur", onBlur);
console.log('focus')
function onBlur() {
console.log('blur')
successCb && successCb()
handler.remove()
clearTimeout(timeout)
document.body.removeChild(target)
};
//will trigger onblur
location.href = url
// Note: timeout could vary as per the browser version, have a higher value
var timeout = setTimeout(function () {
console.log('setTimeout')
failCb && failCb()
handler.remove()
document.body.removeChild(target)
}, 1000);
}
function _registerEvent(target, eventType, cb) {
if (target.addEventListener) {
target.addEventListener(eventType, cb);
return {
remove: function () {
target.removeEventListener(eventType, cb);
}
};
} else {
target.attachEvent(eventType, cb);
return {
remove: function () {
target.detachEvent(eventType, cb);
}
};
}
}
引入文件：
import { openUrlWithInputTimeoutHack } from '@/utils/arouse'
方式二调用：
openUrlWithInputTimeoutHack('EaglEye:\\', () => {
console.log('未安装');
window.location.href = 'xxx软件下载路径'
}, () => {
console.log('已安装，自动唤起');
})
