Solved using cordova-plugin-file.
Replace:

const url = window.URL.createObjectURL(new Blob([response.data]))
        const link = document.createElement('a')
        link.href = url
        link.setAttribute('download', fileName)
        document.body.appendChild(link)
        link.click()

with:

 var blob = new Blob([response.data])

 if (typeof cordova !== 'undefined') {
     saveBlob2File(fileName, blob)
 }

cordova file plugin code:

     function saveBlob2File (fileName, blob) {
        var folder = cordova.file.externalRootDirectory + 'Download'
        window.resolveLocalFileSystemURL(folder, function (dirEntry) {
          console.log('file system open: ' + dirEntry.name)
          createFile(dirEntry, fileName, blob)
        }, onErrorLoadFs)
      }

      function createFile (dirEntry, fileName, blob) {
        // Creates a new file
        dirEntry.getFile(fileName, { create: true, exclusive: false }, function (fileEntry) {
          writeFile(fileEntry, blob)
        }, onErrorCreateFile)
      }

      function writeFile (fileEntry, dataObj) {
        // Create a FileWriter object for our FileEntry
        fileEntry.createWriter(function (fileWriter) {
          fileWriter.onwriteend = function () {
            console.log('Successful file write...')
          }

          fileWriter.onerror = function (error) {
            console.log('Failed file write: ' + error)
          }
          fileWriter.write(dataObj)
        })
      }

      function onErrorLoadFs (error) {
        console.log(error)
      }

      function onErrorCreateFile (error) {
        console.log(error)
      }

Thanks @metalsadman

Now it works!
My lack of understanding how next.router works.

<script lang="ts">

import { defineComponent } from 'vue'
import { useRouter, useRoute } from 'vue-router'

export default defineComponent({
  setup() {

    const router = useRouter()
    const route = useRoute()

    function onClick() {
        router.push({
        path: '/home'
      })     
    }

    return { onClick };
  }
  })
</script>

How can I get a router reference inside a click handler ?

<template>
  <div>
      <q-btn color="primary" label="Submit" @click="onClick" />
  </div>
</template>

<script lang="ts">

export default {
    setup() {

    function onClick() {
        console.log('onClick'); 
        //router.replace({ path: '/home' })       
    }

    return { onClick };
  }
}
</script>

Thank you @s-molinari !

There is something strange about the ordering in the QTable examples in the documentation (V1)

see Basic example

It seems that by pressing on a column the sorting passes cyclically

1. ascending
2. descending
3. not ordered

It’s not what I expect.

If I always click on the Calories column I expect:

1. ascending
2. descending
3. ascending
4. descending
5. ascending
6. descending
   …

In the declaration of a column the sort field is defined as:
function (a, b, rowA, rowB)
Why not add a descending parameter (true / false)?

The only example in the QTable documentation that behaves as I expect is the Custom sorting

Did I miss something?

Hi all,
my spa application download a file with the code below:

this.$axios.post('/api/v1', { url: url, retType: 'excel' },
        { responseType: 'blob' }).then(function (response) {
        const url = window.URL.createObjectURL(new Blob([response.data]))
        const link = document.createElement('a')
        link.href = url
        link.setAttribute('download', fileName)
        document.body.appendChild(link)
        link.click()
        $q.loading.hide()
      }).catch(function (/* error */) {
        $q.loading.hide()
      })

It works fine even in chrome on my android phone (pie).
I built the android cordova app; it works but when I press the button to download the file it silently fails.
Do you think the problem is some permission missed on the manifest or do I need to use a cordova plugin ?

Is this the problem?

window.URL.createObjectURL()

Thanks

Thank you mKomo, it works!
I’m just a newbie.

Hello guys,

I’m struggling with my first electron app.

A button triggers a rest api call:

this.$axios.post(’/api/v1’, …

It fails (Network Error) …

Where do I configure my app to use the real url?:
http://<server>:<port>/api/v1

I have had no problems with the spa version.

Thanks
