How to call order function from successCallback ? The code is vuejs

Answer 1

Would be easier if the code you posted would be complete but my guess is:

Use arrow functions

var successCallback = payment_id => {
 // now "this" refers to this vue component instance so:
 this.order()
}

or store reference to this and use it like a variable

var that = this
var successCallback = function (payment_id) {
 // this is *this* function
 // "that" is a vue instance
 that.order()
}
