I am trying to call a controller function from js and use the result for validation purpose.
Unfortunately, the result getting as `undefined` because of the result line is printing before the completion of the ajax call.

here is my code:

***.js**

send: function(e){
e.preventDefault();
var self = this;
var is_submit = self.$target.find('#is_submit').val();
var mobile = self.$target.find('#mobile').val();
var phone = self.$target.find('#phone').val();
var data = self.ajaxcall(mobile,e);
console.log('dddddddd',data);// here it prints undefined.
if (data == false){
return false;
}
this._super(e);

},
})


ajaxcall:function(mobile,e){
var value = {
'flag':'mobile',
'number':mobile
}
ajax.jsonRpc('/checkexisting/','call',value).then(function(data){
console.log('isnide ajax call',data);
return data;
});
},

Here is th console output:

Have you tried $.when() ?

Grep for examples in the mail module js folder...

@Pablo Guerra, I searched this in the source code and found it. But i didn't understand. Could you give a concrete solution?

I'm not sure if it works. something like

var xyz

xyz= ajax.jsonRpc('/checkexisting/','call',value) //I'm assuming that this returns some value from server.

$.when(xyz).pipe(function(result){return result}))
