去掉element中input type=number尾部上下小箭头以及上下滚动，input框里值变动的效果

引用element中的input type=number组件

<el-input type="number" v-model.number="numberData"></el-input>

去掉input type=number尾部上下小箭头采用CSS样式重置的方式

/* element样式重置 start */
/* 去掉input尾部上下小箭头 start */
input::-webkit-outer-spin-button,input::-webkit-inner-spin-button{
  -webkit-appearance: none !important;
  -moz-appearance: none !important;
  -o-appearance: none !important;
  -ms-appearance: none !important;
  appearance: none !important;
  margin: 0;
}
input[type="number"]{
  -webkit-appearance:textfield;
  -moz-appearance:textfield;
  -o-appearance:textfield;
  -ms-appearance:textfield;
  appearance:textfield;
}
/* 去掉input尾部上下小箭头 end */

去掉上下滚动鼠标，input type=number框里值变动的效果
在el-input加上@mousewheel.native.prevent来阻止鼠标滚动

<el-input type="number" v-model.number="numberData" @mousewheel.native.prevent></el-input>
