Vue3新增时自动获取当前时间的操作方法
作者：小宋1021
这篇文章主要介绍了Vue3新增时自动获取当前时间的操作方法,本文通过实例代码图文相结合给大家介绍的非常详细,感兴趣的朋友跟随小编一起看看吧
如图，点击新增的时候自动获取当前的时间来作为创建时间
时间组件：
<el-form-item label="创建时间" prop="createTime">
<el-date-picker
v-model="createTime"
type="datetime"
value-format="x"
placeholder="选择创建时间"
/>
</el-form-item>formData：
const formData = ref({
id: undefined,
courseType: undefined,
subject: undefined,
fileType: undefined,
appendixName: undefined,
creator: userStore.user.id,
createTime: undefined,
})const createTime = ref('')打开弹窗时给创建时间赋值：
/** 打开弹窗 */
const open = async (type: string, id?: number) => {
createTime.value = dateFormat()
dialogVisible.value = true
dialogTitle.value = t('action.' + type)
formType.value = type
resetForm()
userList.value = await UserApi.getSimpleUserList()
// 修改时，设置数据
if (id) {
formLoading.value = true
try {
formData.value = await ResearchingManageApi.getResearchingManage(id)
formData.value.createTime = createTime.value
} finally {
formLoading.value = false
}
}
// 获得登录人名称
userList.value = await UserApi.getSimpleUserList()
userList.value.forEach((item) => {
if (item.id === userStore.user.id) {
creator.value = item.nickname
}
})
}获取时间方法：
const dateFormat = ()=>{
let date = new Date();
let y = date.getFullYear();
let MM = date.getMonth() + 1<10? ('0' + (date.getMonth() + 1)) : date.getMonth() + 1;
let d = date.getDate()< 10 ? ('0' + date.getDate()) : date.getDate()
let h = date.getHours() < 10 ? ('0' +date.getHours()) : date.getHours();
const m = date.getMinutes()< 10 ? ('0' + date.getMinutes()) : date.getMinutes();
let s = date.getSeconds() < 10 ? ('0' +date.getSeconds()) : date.getSeconds();
console.log( y + '-' + MM + '-' + d + ' ' + h + ':' + m + ':' +s)
return y + '-' + MM + '-' + d + ' ' + h + ':' + m + ':' +s
}为了怕大家找不到代码应该放在那里，我就在下面放上完整代码，大家自行查找，谢谢大家。
