//vue
data(){
return{
name:"test",
age:18,
}

methods:{
getData(){
$.ajax({

type:"post",
data:{
"name":this.name,
"age":this.age,

} because this is written in $.ajax () parentheses, here data is only equivalent to an incoming object parameter (the data format here is an object), and I misunderstand that the method is not called.
and the this in the subsequent callback function points to one of the built-in objects in ajax that calls his object rather than the other. The this of the
callback function points to the AJAX configuration object ajaxSettings of jQuery. Inside jQuery, s.success is used instead of the callback function passed in, and the calling object of success is s, which is the abbreviation of ajaxSettings object. Also note that the ${this} in the callback function does not point to this jQuery but to the object s above.
