vue.js实现自定义输入分页

效果如下：

html：

<input type="text" value="1" v-model="page.page_my_selected" @blur="onBlur">

js：

dara(){
    return {
         page:{page_my_selected:1}
    }
}

onBlur() {
      if (
        this.page.page_my_selected == null ||
        this.page.page_my_selected == undefined ||
        this.page.page_my_selected == ""
      ) {
        this.page.page_my_selected = 1;
      }
      let reg = /^\d+$/;
      // 输入字符串
      if (!reg.test(this.page.page_my_selected)) {
        if (reg.test(this.page.page_my_selected.substr(0, 1))) {
          this.page.page_my_selected = parseInt(this.page.page_my_selected);
        } else {
          this.page.page_my_selected = 1;
        }
      }
      /    / console.log(reg.test(this.page.page_my_selected))
    },
