本篇內容介紹了“ant design vue的form表單如何取值”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！
因為不是很熟悉，所以還是查了文檔找了一下使用方式，剛開始查到的文檔是這樣寫的
然后返回了undefined，后來又查詢了一些文檔，發現我多加了一個props屬性，然后使用第二個方法成功了，代碼如下：
1、可通過 v-decorator 進行表單驗證
//內置驗證規則
<a-form-item label="課程名稱"
v-bind="formItemLayout">
<a-input placeholder="課程名稱"
v-decorator="['name', { rules: [{ required: true, max: 50, message: '必填項，最大50字符' }] }]" />
</a-form-item>
//自定義驗證規則01
<a-form-item>
<a-input size="large"
type="text"
placeholder="手機號"
v-decorator="['mobileNumber',
{rules: [{ required: true, pattern: /^1[34578]\d{9}$/, message: '請輸入正確的手機號' }], validateTrigger: 'change'}]">
<a-icon slot="prefix"
type="mobile"
: />
</a-input>
</a-form-item>
//自定義驗證規則02
<a-form-item v-bind="formItemLayout"
label="手機號碼">
<a-input placeholder="手機號碼"
v-decorator="['mobileNumber',{rules: [{ required: true,max:11,message:'請輸入正確格式的手機號碼',validator:MobileNumberValidator}]}]" />
</a-form-item>//在methods中設定方法
// 手機號驗證
MobileNumberValidator (rule, value, callback) {
const idcardReg = /^1(3|4|5|6|7|8|9)\d{9}$/
if (!idcardReg.test(value)) {
// eslint-disable-next-line standard/no-callback-literal
callback('非法格式')
}
// Note: 必須總是返回一個 callback，否則 validateFieldsAndScroll 無法響應
callback()
}2、可通過 v-decorator 進行內置的雙向綁定（詳情可看下文的數據獲取與填充）
數據填充（所有項） this.form.setFieldsValue(data)
數據獲取（所有項） this.form.validateFields(async (errors, values) => {
console.log(values)
});3、可通過 v-decorator 的initialValue設置初始值
<a-form-item label="課程名稱"
v-bind="formItemLayout">
<a-input placeholder="課程名稱"
v-decorator="['name', { initialValue:'姚峰', rules: [{ required: true, max: 50, message: '必填項，最大50字符' }] }]" />
</a-form-item>4、下拉選擇框的 labelInValue 屬性
通常情況下，通過this.form.getFieldValue(“courseTeacherList”)，你只能獲取一個數組包含value值，形如[‘7’,‘10’]，而通過labelInValue屬性可以得到[{key: “7”,label: “王鳳”},{{key: “10”,label: “姚峰”}}]
key表示value
label表示顯示值
<a-form-item label="教師"
v-bind="formItemLayout">
<a-select mode="multiple"
labelInValue
placeholder="請選擇教師"
v-decorator="['courseTeacherList', { rules: [{ required: true, message: '必填項，請選擇教師' }] }]">
<a-select-option v-for="item in teacherList"
:key="item.id"
:value="item.id">{{ item.name }}</a-select-option>
</a-select>
</a-form-item>5、type類型檢驗
Type string: Must be of type string. This is the default type. number: Must be of type number. boolean: Must be of type boolean. method: Must be of type function. regexp: Must be an instance of RegExp or a string that does not generate an exception when creating a new RegExp. integer: Must be of type number and an integer. float: Must be of type number and a floating point number. array: Must be an array as determined by Array.isArray. object: Must be of type object and not Array.isArray. enum: Value must exist in the enum. date: Value must be valid as determined by Date url: Must be of type url. hex: Must be of type hex. email: Must be of type email. any: Can be any type.
//獲取一個輸入控件的值 Function(fieldName: string)
let myDate = this.form.getFieldValue("startDate");
//獲取一組輸入控件的值，如不傳入參數，則獲取全部組件的值 Function([fieldNames: string[]])
let value = this.form.getFieldsValue(["startDate","endDate"]);
let value = this.form.getFieldsValue();
//設置一組輸入控件的值
this.form.setFieldsValue({
startDate:res.result["startDate"],
endDate:res.result["endDate"],
})
//設置一組輸入控件的值 加了labelInValue屬性
this.form.setFieldsValue({
userName:{
label:res.result["userName"],
key:res.result["userNameId"]
}
})
//設置表單數據 對日期、下拉框含labelInValue屬性的form控件的數據設置要特殊處理才能綁定
//對于日期控件需要將string類型的數據轉換moment類型
//對于下拉框含labelInValue屬性控件，數據需要轉換成key、label的對象格式
import moment from 'moment'
setFormValues (record) {
// 控制教師
if (courseTeacherList && courseTeacherList.length > 0) {
record['courseTeacherList'] = courseTeacherList.map(item => ({
key: item.teacherId + '',
label: item.teacherName
}))
}
const fields = ['courseTeacherList', 'certificateNo', 'cardTime', 'termValidity', 'documentStatus', 'remark']
Object.keys(record).forEach((key) => {
if (fields.indexOf(key) !== -1) {
this.form.getFieldDecorator(key)
const obj = {}
if (key === 'cardTime' && record['cardTime'] != undefined) {
obj[key] = moment(data[key], 'YYYY-MM-DD')
} else {
obj[key] = record[key]
}
this.form.setFieldsValue(obj)
}
})
},
//關閉表單清空表單數據
this.form.resetFields();
//提交表單獲取數據
//通過this.form.validateFields函數進行表單驗證以及數據獲取
//對于日期控件，獲取的是moment類型數據，需要轉換成字符串儲存，
//形如values.birthday = values.birthday ? values.birthday.format('YYYY-MM-DD') : ''
handleSubmit () {
const { id } = this
this.form.validateFields((err, values) => {
if (!err) {
this.submitLoading = true
values.birthday = values.birthday ? values.birthday.format('YYYY-MM-DD') : ''
// 處理教師
values.courseTeacherList = values.courseTeacherList.map(item => {
const obj = {}
obj.teacherId = Number(item.key)
return obj
})
if (id) {
// 修改
updateCourse({ id, ...values }).then(res => {
if (res.code == 0) {
this.$message.success('保存成功')
this.form.resetFields()
this.$router.back()
} else {
this.$message.error('保存失敗，請稍后再試')
}
}).finally(() => {
this.submitLoading = false
})
} else {
// 添加
addCourse(values).then(res => {

this.$message.success('保存成功')
this.form.resetFields()
this.$router.back()
} else {
