关于input框只能输入纯数字问题

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

 inputChange(e) {
      let timer = setTimeout(() => {
        this.form.name = parseInt(e)
        clearTimeout(timer)
      }, 100)
    },




环境：vue ,elemnt ui
