如何在 Vue.js 中将输入保存到本地存储中的输入

Question

例如，我从官方 Vue.js 站点做所有事情。但我需要使用框架 7。在输入中我显示了 [object InputEvent]。当我尝试写一些文本时，也会显示 [object InputEvent]。

如何将名称保存在本地存储中并在输入中显示出来？

PS 框架 7 中的 v-model 不工作

  <f7-list form>
    <f7-list-input
      label="Username"
      name="username"
      placeholder="Username"
      type="text"
      v-bind:value="name"
      required validate
      pattern="[3-9a-zA-Zа-яА-ЯёЁ]+"
      @input="persist"
    />
  </f7-list>

<script>
export default {
data() {
    return{
        name: '',
        }
    },
mounted() {
  if (localStorage.name) {
    this.name = localStorage.name;
  }
},
methods: {
        persist(){
            name=$event.target.value;
        localStorage.name = this.name;

    }
}
};
</script>

that's what output to input

Answer 1

简单：

localStorage.setItem('name', this.name)

this.name = localStorage.getItem('name')

Answer 2

使用正确的 localstorage 方法更新了代码并删除了导致您的问题的一行

替换

name=$event.target.value;

和

this.name = $event.target.value;

请在下面找到包含更新方法和重构代码的更新代码。

 <f7-list form>
        <f7-list-input
          label="Username"
          name="username"
          placeholder="Username"
          type="text"
          v-bind:value="name"
          required validate
          pattern="[3-9a-zA-Zа-яА-ЯёЁ]+"
          @input="persist"
        />
      </f7-list>

    <script>
    export default {
    data() {
        return{
            name: '',
            }
        },
    mounted() {
      if (localStorage.name) {
    //retrive name from localstorage here.
        this.name = localStorage.getItem('name')
      }
    },


     methods: {


                 persist(){
           /* set name to localstorage here
  using setItem is recommended  way of doing but even without that yourcode should work.*/
                    localStorage.setItem('name', $event.target.value)

            }
        }
        };
        </script>
