怎么在app上添加图标和文字

 window.showAddMenu = this.addSearch
    let data = {
      type: 'ICON',
      text: 'https://static-image.lexing360.com/vehicle-menu-add.png',
      functionName: 'showAddMenu'
    }
    try {
      window.JSBridge.navigationTo('menuText', JSON.stringify(data))
    } catch (e) {}

  addSearch () {
      navigationTo('/searchCar/addSearchCar')
    }

import router from '@/router/index'
import vThis from '@/main'

function navigation (route, closeBefore = false) {
  if (process.env.NODE_ENV === 'dev') {
    router.push(route)
  }
  if (window.logInfo.mobile === 'iPhone' && window.JSBridge && !closeBefore) {
    window.JSBridge.navigationTo('web', window.location.protocol + '//' + window.location.host + '/#' + route)
  } else if (window.logInfo.mobile === 'iPhone' && window.JSBridge && closeBefore) {
    const version = 0x01040400
    if (vThis.GLOBAL.appInfo.version >= version.toString(10)) {
      window.JSBridge.navigationTo('singleWeb', `${window.location.protocol}//${window.location.host}/#${route}`)
      return
    }
    window.JSBridge.navigationTo('web', `${window.location.protocol}//${window.location.host}/#${route}`)
  } else {
    router.push(route)
  }
  // router.push(route)
}

export default navigation
