How do I get the return value of this function to be inserted into the field where you are running KeyUp?
<input type="text" v-model="valor_calc_dinheiro" v-on:keyup.stop.prevent="mascara_dinheiro($event.target.value)" ref="valor_calc_dinheiro">
mascara_dinheiro : function(valor){
v=valor.replace(/(\d{1})(\d{1,2})$/,"$1.$2")
alert(v);
},
Pass only the event and thus you have the event.target available for example ...
That is:
<input type="text" v-model="valor_calc_dinheiro" v-on:keyup.stop.prevent="mascara_dinheiro($event)" ref="valor_calc_dinheiro">
And then in the method:
mascara_dinheiro: function(e){
const v = e.target.value.replace(/(\d{1})(\d{1,2})$/,"$1.$2")
alert(v);
e.target.value = v;
},
Note: Note that I put const v and not only v . You should avoid global variables, it is always important to declare variables before using them. You can read more about it here: var, const, or let? Which one to use?
