关于input框只能输入纯数字问题

1  <el-form-item label="支付商户号" class="pay_number">
2         <el-input @input="inputChange" v-model="form.name" type="number" ></el-input>
3       </el-form-item>

1  inputChange(e) {
2       let timer = setTimeout(() => {
3         this.form.name = parseInt(e)
4         clearTimeout(timer)
5       }, 100)
6     },
