Perform an action upon a successful completion of an AJAX request using Axios by utilizing the `then()` method for chaining

Question

Perform an action upon a successful completion of an AJAX request using Axios by utilizing the `then()` method for chaining

I'd like to trigger a specific action when an ajax call is successful in axios


    save() {

      this.isUpdateTask ? this.updateProduct() : this.storeProduct()

      this.endTask()

    }

When the ajax call to update or store the product succeeds, I want to execute the endTask() function.

I only want the endTask() function to be executed if the ajax call is successful.

How can I achieve this?

The store function:


    storeProduct() {
      return axios
        .post("products", this.getFormData())
        .then(
          response => this.products.push(response.data.data)
        )
        .catch(
          error => (this.serverErrors = error.response.data.errors.detail)
        )
    },

javascript ajax vue.js axios

Answer №1

If you want to implement these methods within a new promise, you can use the example provided below:


   save() {
      Promise.resolve()
      .then(() => {
        return this.isUpdateTask ? this.updateProduct() : this.storeProduct()
      })
      .then(() => {
        this.endTask()
      })
    }

There are other approaches as well:

save() {
  (this.isUpdateTask ? this.updateProduct() : this.storeProduct()).then(() => {
    this.endTask()
  })
}

You can also assign it to a variable:

save() {
  const promiseUpdate = this.isUpdateTask ? this.updateProduct() : this.storeProduct()

  promiseUpdate.then(() => {
    this.endTask()
  })
}

Alternatively, you can use async/await:

async save() {
  await this.isUpdateTask ? this.updateProduct() : this.storeProduct()
  // This code will only run if everything happens successfully
  await this.endTask()
}

The reason why the endTask is executed even when the response is not successful is because you handle the error within the storeProduct function.

.catch(
  error => (this.serverErrors = error.response.data.errors.detail)
)

In this case, it is necessary to re-throw the error:

.catch(
  error => {
    this.serverErrors = error.response.data.errors.detail
    throw error
  }
)

The catch method in Promise has the same effect as using try/catch in JavaScript.
