javascript - vuejs方法中的Parseint

Question

例如让 this.last 为 5 和 this.current 60 ，我想要 this.last + this .current 为 65 而不是 60 5. 我尝试了 parseInt(this.last + this.current) 但它不起作用

<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

首先，不要初始化this.current至 " "但到0 .

您还应该将输入字段的类型更改为 <input type="number"> .

要将两个数字相加，请使用:

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