electron中使用 alert和comfirm等弹出框都会致使input无法获得焦点

问题如题所示

解决方法：

const {dialog} = require('electron').remote;
alert = function(str){
  var options = {
    type: 'warning',
    buttons: ["Ok"],
    defaultId: 0,
    cancelId:0,
    detail:str,
    message: ''
  }
  dialog.showMessageBoxSync(null,options)
}
