How to save data in Vue instance
The question is quite simple,
All I want is to get the data after the AJAX post saved in Vue instace's data.
Here is my code:
const VMList = new Vue({
el: '#MODAL_USER_DATA',
data: {
user: //,
//userAcc:
},
methods: {
getUserAcc: function ( userID ) {
this.user = { _id : userID };
var self = this
$.ajax({
url: "/listuser",
type: "POST",
data: this.user,
success: function(data) {
this.user = data ;
//this.userAcc = Object.assign({}, this.userAcc, data );
alert(JSON.stringify(this.user));//show the user correctly (e.g user = data)
$('#popupDeleteModal').modal('show');
alert(JSON.stringify(data));//show data,the entire json object,everything is good
},
error: function(err) {
console.log('error: ',err);
},
});
}
}
});
And after I trigger the getUserAcc(id) method,I try to verify the VMList.user value in browser console,and I get only the id.Seems like after the function is over the data is reset.How could I store the data from the AJAX post request in the user object from data:{...} ?
Thank you for help!!!

The problem is that this inside your ajax return function doesn't refer to the vue instance anymore.
The solution is to save the this keyword into a variable inside the function. Example:
getUserAcc: function ( userID ) {
var that = this;
this.user = { _id : userID };
$.ajax({
url: "/listuser",
type: "POST",
data: this.user,
success: function(data) {
that.user = data;
//Rest of your code
},
error: function(err) {
console.log('error: ',err);
},
});
}
