硬件开发工程师薪资网站seo的优化怎么做
在前端的处理中，表单的处理永远是占高比例的。在BOM+DOM+js的时候是这样，在Vue的时候也是这样。Vue的表单处理做了特别的优化，如值绑定、数据验证、错误提示、修饰符等。
表单组件的示例：
<script setup lang="ts">
import {ref} from "vue"
import axios from "axios"const name=ref("");const gender=ref("");const birthDate=ref("");const phone=ref("");const applyReason=ref("");const scopes=ref([]);const luckyNumber=ref(1);function submitForm(){axios({method:"post",url:"",params:{name:name.value,gender:gender.value,birthDate:birthDate.value,phone:phone.value,applyReason:applyReason.value,scopes:scopes.value,lunckyNumber:luckyNumber.value}}).then((res)=>{console.log(res);});}function resetForm(){name.value="";gender.value="";birthDate.value="";phone.value="";applyReason.value="";scopes.value=[];luckyNumber.value=1;}
</script><template>
<form><div><div>姓名:<input v-model="name" id="name" placeholder="input your name"/></div><div>性别:<input type="radio" value="male" id="male" v-model="gender"/><lable for="male">男</lable><input type="radio" value="female" id="female" v-model="gender"/><lable for="female">女</lable></div><div>出生日期:<input type="date" id="birthDate" v-model="birthDate"/></div><div>手机号码:<input type="text" v-model="phone"/></div><div>申请理由:<textarea v-model="applyReason" placeholder="add reason here"></textarea></div><div>涉猎范围:<input type="checkbox" id="reading" value="reading" v-model="scopes"/><lable for="reading">阅读</lable><input type="checkbox" id="sports" value="sports" v-model="scopes"/><lable for="sports">运行</lable><input type="checkbox" id="dreaming" value="dreaming" v-model="scopes"/><lable for="dreaming">冥想</lable><input type="checkbox" id="playing" value="playing" v-model="scopes"/><lable for="playing">操作</lable></div><div>幸运数字:<select name="select" v-model="luckyNumber"><option selected>1</option><option>2</option><option>3</option><option>4</option><option>5</option><option>6</option><option>7</option><option>8</option><option>9</option></select></div><div><button type="button" @click="submitForm">提交</button><button type="button" @click="resetForm">重置</button></div></div>
</form>
</template><style></style>v-model在Vue中有三种修饰符：
v-model.lazy ：由原来的input事件之后更新v-model的值改为change事件之后更新v-model的值，这对复合组件和计算属性有很大的作用
v-model.number ：用户输入的内容会被自动转换为数字，输入框有type="number"时会自动启用
v-model.trim ：用户的输入内容会自动去除两端的空格
