Using Parseint in a Vue.js method

For instance, let's say this.last is 5 and this.current is 60. I want the sum of this.last + this.current to be 65, not 605. I attempted using

parseInt(this.last + this.current)
but it did not work as expected.

<button class="plus" @click="plus">+</button>
<input class="res" v-model="current" maxlength="24" disabled>
<input class="res2" v-model="last" maxlength="24" disabled>
button{
width:200px;
height:200px;
}
data:{
  last: null,
  current: " ",
  plusClicked: false
}
methods:{
  plus:function(){
   this.last = this.current;
   this.current = " ";
   this.plusClicked = true;
  },
equal:function(){
  if(this.plusClicked == true){
   alert(parseInt(this.last + this.current));
   this.plusClicked = !true;
  }
}},

Answer №1

To start off, it is recommended not to set this.current as " ", but rather as 0.

Another important step is to adjust the input field type to <input type="number">.

In order to sum up both numbers, you can use:

  • parseInt(this.last) + parseInt(this.current)
