Delay with Vue.js v-bind causing form submission to occur before the value is updated

Question

Delay with Vue.js v-bind causing form submission to occur before the value is updated

Trying to update a hidden input with a value from a SweetAlert modal, but encountering issues.

The following code isn't working as expected - the form submits, but the hidden field's value remains null.

HTML:

<input type="hidden" name="input" v-model="value">

JavaScript:

this.value = websiteId;
event.target.submit();

On the other hand, the code below seems to do the trick. However, it raises questions about the necessity of using Vue.js over plain JavaScript.

HTML:

<input type="hidden" class="input-value-web" name="input" value="0">

JavaScript:

document.querySelector('.input-value-web').value = websiteId;
event.target.submit();

javascript vue.js

Answer №1

When you modify a Vue instance's data property value, such as with this.value = websiteId, the associated element won't reflect the change until the next update cycle.

However, the update won't happen until all actions in the method are completed.

To address this issue, utilize the $nextTick method to ensure that the Vue instance has updated before triggering event.target.submit().

Check out this sample code:

methods: {
  submitForm() {
    this.value = websiteId;
    this.$nextTick(() => {
      event.target.submit();
    });
  }
}
