What is the process for updating information in Vue.js?

I need assistance with displaying the updated data in a modal. When I trigger the testing(data) function through a click event, the data appears correctly within the function. However, the template does not update and still shows the previous data. How can I resolve this issue?

Here is the script:

 function testing(data) {
   const testingLink = new Vue ({
     el: '#test',
     data: { selected: data }, 
     methods: {
       showDialog: function() { $("#test).modal() }
     }
  })
  testingLink.showDialog()   
 }

Answer №1

It is not recommended to instantiate a Vue Instance within a repeatable function. Consider the following approach instead:

   const exampleLink = new Vue({
     el: '#example',
     data: { selected: null }, 
     methods: {
       openDialog: function(data) { 
          this.selected = data
          $("#example").modal() 
       }
     }
   })

exampleLink.openDialog(YOUR_DATA_TO_BE_PASSED)
